    Hey all. Has anyone ever compared these two amps side by side for sonic differences? I currently own the st-120 and Roy's SP-14 and the combo works very well. I recently purchased a McIntosh D100 digital preamp which I use as a dac. Wow, my ears woke up when I heard this thing. I'm wondering how the entry level McIntosh stuff (C-220 pre and MC-275) may compare. Any thoughts?

    Thanks,
    Leigh

    Hi Leigh,

    Indeed, I have a ST-120 and a MC-275/V and.... I'm using it with a C-2300 and a D-100 as DAC...
    I have read many comments on this forum about both amps and I always wonder.....are people comparing
    both amplifiers with 100% tubes ?..... If either amp has worn tubes, it will likely sound less....
    My 275 has all McIntosh selected tubes and my St-120 has 12BH7 and 6550 by Tube Amp Doctor...
    (Alternatively I have 12au7 and either KT-120 - very hot ! - or Gold Lion KT88 - different rectifiers like GZ37NOS, 5U4, etc.)

    Both are used on rather easy to drive Tannoy Glenair 10 with supertweeter (4 Ohm total).

    So, does the ST-120 "blow the Mc-275 out of the water"? NO, at least not in my opinion.
    Is it far more value for money? YES ! It does sound as good for far less money ( a 275MkV costs
    the equivalent of 6.300 $ overhere in Europe, while the ST-120 comes to about 2.100 $ built....
    (we have 21% VAT, import duties 10% .....)

    IMHO, you can't go wrong with either one in terms of sound....but when considering price.... at 1/3th....
    As so many I do love McIntosh, their history, the "pride of ownership" etc.... if this is worth the
    money is something each individual has to decide for him-(her)self...

    In my experience it is worth the effort to compare 4-8 Ohm taps..... in my situation, on both amps,
    4 Ohm tap sounds better than 8 Ohm......ST-120 is wired accordingly.

    The ST-120 is a magnificent amplifier and is worth every penny. Sound is marvellous!

    Somewhat related ... I got the ST120 to replace an MC2205 (solid state - 200wpc) that was in need of some shop time. Bought that new back in 1980ish. I know that had some issues, mostly with lights, meters, and the power guard system. Can't really say how well it compared with it's original spec, but I can say with the Latino, there hasn't been much incentive to git er done on the Big Mac.

    One important observation ... the MC2205 would hard clip at the same system levels that I drive the ST120. I (may) get some distortion now, but not so you'd notice. BIG advantage with the tubes. It was also common to see the caution lights on my XR16 speakers - now I'll see those once in a blue moon.

    One day I'll get the MC2205 to the bench so I can do a true comparison ... have to find my back belt first though ... right now, it's still in the rack, just taking up space.

    The MC-2205 is a very fine amp in its own right. At this moment I'm listening to Chet Baker through two
    old MC-50 mono's. (both revised by McIntosh TS)
    Do they compare to the ST-120 ? No way, the sound is less defined, less dynamic and even a bit "coarse"
    at times.
    But that does not diminish my musical satisfaction. These are 45 years old (after all...) and are a perfect
    sample of what was possible in those days..... which was a lot. It is just great fun to listen to them....

    Thanks so much for the input on the Mac-275 and the ST-120 people. So much appreciated and well received. I now think I have a hankerin' to check out the M125's over the Mac. And a special thanks to Bob for the link!

    And in the US, that $6,500 for the MAC compares to about $1,500 for the ST120 - over 4x the cost!

    Yes, McIntosh products ARE expensive. But...

    Their build quality is second to none. For example, the switches are magnetically activated blades inside a nitrogen-atmosphere glass bottle. No oxidation. YEARS of reliable service.

    There are no analog pots & wipers in Mac products - Instead, digital ladder switches mate to pairs of attenuator resistors (laser trimmed for accuracy).

    Some don't care about component longevity - but if you do, McIntosh offers it. At a premium price...

    Further, if resale value is of interest, the resale on Mac gear is some of the highest around.

    I won't argue that TFHF gear provides as good a performance for a quarter of the cost. But I can understand how someone willing to pay for McIntosh could say that they got their money's worth.

    The Mac will meet its factory specs after 10 years or even 20 years of use. (ignoring replaceable items such as tubes). Most other gear won't. And the more complex the item, the greater the advantage of "overbuilding" becomes.

    Now before anyone jumps on me for being a "Mac Moron," let me say that I don't own any McIntosh gear. But I have in the past (and may again). Whether or not Mac justifies its cost is debatable. Whether or not it's better-built is NOT.

    My amp just gets better over time. When I originally bought my vta st 70, I'm sure there had been no comparisons to legendary gear like the Macintoshes made here abouts, and I wouldnt have dreamed up the question myself. So it comes as a time-delayed bonus value to learn how this gear stacks up in such comparisons.

    I picture Roy and Bob grinning from ear to ear.

    I have not had the opportunity to hear some of the newer McIntosh gear. Some may not know that McIntosh, since October of 2012, was bought out (100% buyout) by an Italian holding company Fine Sounds SpA. Over the last 4 years the Italian holding company has had the final say on all McIntosh products. Actually, since 1990, McIntosh has been wholly owned by some foreign (outside the USA) company. You can read about how McIntosh was sold in 1990 and resold again in 2003, then resold again 2008 and then again in 2012 at the link below.

    I love both my Mc275-V as well as my ST-120, so forgive me, please..... There must be a reason why McIntosh is so much sought after and holds its value even after 40 yrs.
    There must be something good about is.

    The company, just like the amps they make, is something people want to buy!

    There's obviously a lot to like about those amps. I saw one in a hi fi store back in 1981, and had no idea what it was, but was smitten just by the looks of it. Boldly, unapologetically sporting those tubes for all to see!

    I'd surely have one if I weren't cheap. I think I'll stick with the dynacos, but I sure admire those Macs!

    Despite the changes in ownership, McIntosh still honors its warranties. I have an authorized repair shop less than an hour from my home. I've NEVER taken an item in for repair that they couldn't find parts for, no matter how long ago it was produced.

    When Mr. Latino passes away (heaven forbid, but it's inevitable eventually), will there be anyone to take over the warranties on Tubes4HiFi products? Will the brand even survive the original owner?

    And what does that say about the future resale value of the TFHF products?

    I'm NOT trying to cast aspersions on the quality or value of TFHF. But I am stating facts.

    McIntosh has a much longer history. Despite multiple changes in ownership, there is continuity of customer care and warranty service. Mac parts are available in virtual perpetuity. Mac resale prices reflect these advantages.

    Now all that said, I'm the new owner of a TFHF ST-120. And I'm expecting great things of it!

    Let me attempt to put your mind at rest.
    Were, Dog forbid, Mr. Latino to be hit by a falling meteor tomorrow afternoon, we would mourn first. BUT - there are bright lights at the end of the funnel! Bob's (and Roy's) designs are not secret fornulae, known only to them. There are many among us ready and able to take up the VTA torch. Audiobill comes to mind first. But he's not alone. Any one of us who's actually built an amp knows more than any Mac owner about his hardware.
    What would happen to the Big Mac if same were to occur? Think about THAT...You'd eventually pay shipping to some country you've never heard of to replace a diode, which in the VTA universe, would be accomplished before you could say "Svengali". Ever deal with Audio Research, a company with similar pedigree? I have. You don't want to.

    I think you'll find our support system is at least as secure - and certainly more economical - than any McIntosh can offer. And We Will Survive.

    Kentley says: "Bob's (and Roy's) designs are not secret fornulae" - so THAT's why there are no schematics!

    Kentley says: "Audiobill comes to mind first. But he's not alone." - and he's just as old as Mr. Latino?

    Kentley says: "Any one of us who's actually built an amp knows more than any Mac owner about his hardware." - True - but the MAJORITY of consumers haven't "actually built an amp."

    Kentley says: "And We Will Survive." - And I say "time will tell..."

    PeterCapo says: "As long the documentation stays with the amp and Mouser and Digi-Key are in business, there shouldn't be a problem" - Unless the owner isn't competent to diagnose (the hard part) or fix (the easy part) their own equipment.

    So ultimately, the question is: "Is Tubes4HiFi a kit company, or are they a finished-component company?" I'd argue that the majority of stuff sold is probably sold pre-assembled and to consumers who wouldn't know which end of a soldering iron to hold onto. And for THOSE consumers, having warranty service and authorized repair centers are going to be IMPORTANT.

    Although TFHF has those things right now, what confidence can ANY consumer have that those things will be available in five years? In ten? The answer, whether you like it or not is simply "none."

    So buy a TFHF product if you can fix it yourself - buy a TFHF product if you plan on keeping it forever - but if you want service, warranty, and resale value - buy a McIntosh.

    Now having said all this - I'm going to reiterate again (although I know it'll go in one ear and out the other) that I don't own any Mac gear. I own TFHF gear because it's a better (much better) value, and because if I need to, I can diagnose & fix it myself. But I'm NOT the average consumer (nor are you, Kentley & PeterCapo). And although I'm comfortable with the choices I've made, I wouldn't recommend TFHF gear to "average consumers" who wouldn't be able to fix their own problems in the future.

    The older the company (despite ownership changes) the more confident people can be that service will be there when it's needed. And sooner or later, every audio component WILL need service.

    Boomzilla,
    you forgot that all importent arts ( transformers etc) are clones of a very well known and copied
    amplifier - dynaco. Noone is worried that one won't find dynaco parts, noone is worried that
    a "dynaco-type" amp cannot be fixed due to lack of documentation. ( give or take obsolete
    tubes ( 7199 ) or some parts, but they all have well-known substitutes).

    I would be more concerned if i had a MAC where the transformers are single-sourced and propetary.

    My authorized Mac repair shop has had transformers before for products as far back as the 1960s (MC240). What they don't stock, they've been able to get.

    And I'd also point out that TFHF transformers are NOT Dynaco transformers. They're bigger.

    I own (and love) McIntosh myself, but there is one thing to consider.....In those turbulent
    days, socially, economic and commercial, WHO can assure me that McIntosh will still exist in 5 years from now ?
    Maybe they will be baught by Samsung or some large Chinese investment cy.....don't say this is impossible..
    Stockholders, certainly those of the younger generation, will most always put profit and cash before brand recognition.
    When the "old school" at Mc retires, I wonder what will happen...

    In the meantime, I enjoy both ST-120 and MC275 in 2 different systems.

    Hi MarcVBelgium -

    I'd contend that the McIntosh name is valuable enough that although owners may change, the brand WILL be in business. How many times have they already changed hands? Maybe a dozen? But their customer service, warranty, and authorized repair centers are unchanged.

    In contrast, what normally happens with "garage brands" is that when the original owner retires or passes away, the equipment owners are left holding the bag. No warranty, no authorized repair centers, no parts. Done. That means that when a component from one of these companies does break (and eventually, they all will) that it's worth whatever a broken component is worth and no more.

    A broken McIntosh unit, by comparison, has residual value because parts ARE available via the authorized repair center network. I can get a brand new glass faceplate, for example for anything Mac has ever made.

    This is the ONLY point that I'm making. I'll not impugn Tubes4HiFi's quality, engineering, or current support network (all of which are exceptional). I'm only saying that if there's any business continuity plan in the works, I've not heard of it.

    May i repeat : dynaco has sold more amps then anyone and these amps ( or clones ) are still
    sold by several firms. Transformers are also made by several firms, large and small.
    The probability that anyone would lack a sparpart for a dynaco-clone is minuscule ( unless
    the amp is munged to an unrecognizable state).

    How many mac-clones exists ? How many sources of transformers ?

    Let's keep this discussion about the audible performances and not keep throwing distrust around please!

    Now having said all this - I'm going to reiterate again (although I know it'll go in one ear and out the other) that I don't own any Mac gear.  I own TFHF gear because it's a better (much better) value, and because if I need to, I can diagnose & fix it myself.  But I'm NOT the average consumer (nor are you, Kentley & PeterCapo).  And although I'm comfortable with the choices I've made, I wouldn't recommend TFHF gear to "average consumers" who wouldn't be able to fix their own problems in the future.

    The older the company (despite ownership changes) the more confident people can be that service will be there when it's needed.  And sooner or later, every audio component WILL need service.

    Cheers - Boomzilla



    Hi Boom...I am the owner of a pair of m125's. I had posted a story some months ago about my local postman dropping in giving a listen to my Latino amplifiers b/c HE is the owner of a McIntosh 275 stereo amplifier. While he was not overly impressed by the m125's aestheticly he was VERY much impressed with there performance, and quality construction. Heavy duty...Industrial. He paid close to $6000.00 for his McIntosh and as you know Bob'amplifier are much more affordable to the average audio enthusiast.
    Now I realize that you admitted the value of Bob Latino's amplifiers are a good one at least for the the consumer who knows the difference between a screwdriver and a hammer.
    Saying this I will admit I am not a student of electronics. If something did happen to the m125's my first call would be to audiobill, however Bob Latino has more than one person with hands on experience and therefore if audiobill was not unavailable I am sure I would be directed to someone else knowledgeable with the mechanics of the m125.
    If nothing was available thru TFHF I am fortunate to have a electronic service store available to me within driving distance who works with tube amplifiers.
    No one can predict the future as to what will happen with any company big or small. I think it's wrong to put everything in one basket to say that purchasing an amplifier or kit (whatever label you choose) from Bob could result in a customer throwing his money out the window if he or she is not mechanilly knowledgeable and handy with a soldering gun.

    That in part is what I got out of your read, which those remarks or impressions IMO are a black eye to a company with a good track record.

    I like reading your posts BOOM but I think you may have stepped over the line a bit with this post.

    I think Boom's concerns about what happens if Bob and Roy go out of business were a little too pessimistic.

    First, it's not true there are no schematics. If you google "VTA ST 70 schematic" you'll see the net is littered with them, so one need not depend on the continued viability of this website or Roy and Bob's companies for that info.

    Second, I think the popularity of these amplifiers is underestimated. VTA amps, most commonly, followed by other modern iterations of the venerable ST 70, are frequently discussed on all the audio boards.

    I suggest finding someone with the technical skills to troubleshoot and repair these things will be an easy thing (so long as there is an internet) for years to come. Maybe decades, if the original ST 70 and how it has fared gives us any clues.

    Compare this to the longevity of a commercially made piece of kit, especially one that runs on silicon. The bits and pieces that go into those things go out of production all the time. I suspect the chances of having a salvageable piece of commercially made/sold gear 20 years from now is more of a crap shoot than a Dynaco-based kit.

    Of course, Boom is in the enviable position of being able to hedge his bets -- he's got the VTA gear he enjoys, as well as a commercially made Macintosh, which appears to be a well supported product.

    The performance of VTA amplifiers vs any other brand is fair enough, but the 'company' comparisons are going to be apples vs oranges comparisons. I think that just about anyone who buys gear from VTA is not going to be a typical consumer of electronic gear. More so, they are going to be boutique buyers who want something different, and probably, but not always, are going to be more hands on with their gear.
    And probably are more of the mainstream income buyers who have some extra money for toys, but not the big buck guys who can buy the latest thing, get excited for a short while, then get rid of it for the latest and greatest from some 'established' company that just blew away the last thing they had.

    I know of one established audio company that was bought out and when that happened, disposed of parts inventory only for reasons that it improved it's balance sheet in some way. So, a lot of parts that were proprietary to the companies products out there were now in the trash. As stated earlier, if I ever need a part for my M125's I can get any of them at just about any electronics parts house. The sole exception would be the output transformer.

    If I were to buy new audio today, and was willing to spend big money, I'd go with Bryston of Canada.
    I like their products, and they back them. But they are not going to sell new for what VTA costs me. And again, I wanted to have the experience of building a system myself and see what it would do.

    VTA fills a nice niche market. At one time Heathkit, Eico, etc offered decent kits. Until I heard of VTA products, I really wished that I was around when you could buy a kit and have fun building it and have something to be proud of at the end. VTA is filling this niche for me, and I am thankful that Bob and Roy have put the effort into all of this.

    Again, it makes sense to compare performance, but it should be obvious that VTA is not a conglomerate, and the stuff offered is simple enough to keep going for decades by a lot of technicians out there.

    Lastly, as for resale, for the amount of money VTA charges, you could spend more on a cruise and have nothing after that to show for it. Resale on this stuff doesn't seem to be much of a consideration for me.
