    You want OCD? I got yer OCD!  clown

    +1 on the DAC, and +1 on the Maverick as well.

    I notice you mention having several hundred albums ... put together a nice digital server, add an ADC, and rip your vinyl to digital. That'll certainly kill some time. Been there, done that, and I still spin the records, but it's nice to be able to just click a mouse when I'm feeling lazy. With a good DAC, you're really not losing any SQ if you're using quality digital rips.

    Big fan of the Maverick TubeMagic here. I'm using their D1+ which also has analog in - something they dropped with the D2 - but I like to get some of that tooby magic on the turntable too. The D1+ acts as a tube buffer as well, allowing me to tailor the sound of the Latino. That opens up a lot of combinations that would be otherwise lacking something. Fer example ... current tube set in the ST120 is a Sylvania 12BH7 center, with Sylvania 5814's in the channels. These would be a bit too dark for my tastes, but swapping a Tesla 6CC42 into the DAC livens it right up ... a match made in heaven!

    Good timing ... I'm currently putting together a late winter project to improve the DAC ...

    - Install a Burson v5 discrete op amp, guaranteed to run rings around the current set.
    - Swap in a Sparkos regulator to lower the noise floor
    - Upgrade the primary couplers (Elna Silmic II)
    - Install a dedicated USB channel (Paul Pang) in the HTPC to clean up the other end of the signal chain. That will be driven by an Acopian dedicated 5v power supply. The card itself is super low noise and tightly clocked, and the only equipment attached to that will be the DAC and ADC. This should completely eliminate any crosstalk or chatter from competing USB devices.
    - Upgrade the USB interconnect (Pangea)
    - Recap the power supply.

    By the time this is done, I'll have doubled my original investment in the DAC, but still figure to be ahead of the game, as even stock, the Maverick outshines a lot of much more expensive options.

    Sounds like the start of a plan. I've got an Emotiva DAC and quite like it; XLR outs for the preamp, too.
    What type server we talking about? Any old Windows/Mac Linux PC work?

    Any FAST computer ... with fast memory. You do need to keep any buffering to a minimum.

    My current build is a fairly current generation ITX motherboard using a 60 watt APU chipset with integrated sound and video. Less load = less heat = less fans = less noise. I went from six case fans howling away on the old build to just the "smart" fans on the chip and power supply. Those barely tick over, keeping the box ultra quiet. I can just barely hear it holding my ear right to the case. Especially important using the dbx expander, as any noise is extremely noticeable.

    I'm also using a full size ATX case for more air and better heat dissipation, once again, all about keeping the fan noise down. Video rated hard drives as well - those are fast and quiet.  

    Fun fact - an ITX board will mount right up in an ATX case, leaving acres of free space. The little black box lower left is a 256 gb solid state drive, completely silent and loaded up with all the programs. There's also two 2 gig drives hiding in there as well, set aside for the music.



    You can also see the ONE expansion slot, which is all I need for the Paul Pang USB card. That's currently hosting a generic USB expansion card with just the DAC and ADC plugged in. Worth keeping in mind, the PP USB card is quite wide, taking up a couple slots, but there's plenty of room to the side.



    As mentioned earlier, that's all about minimizing competition and interference from other USB devices. I do know that even the generic card made a BIG difference in digital noise and jitter.

    The larger case is what will allow me to mount the USB power supply inside, and it fits right in with the rest of the audio gear. Also good to use a heavy duty case to minimize any resonance or sonics ... every little bit helps. This old Bach Media case weighs like a dead horse with a whole lot of internal bracing.



    Oh. Don't forget the front end software. I really really like jRiver's Media Center. If MC can't do it, it don't need to be done. Bit of a learning curve for the advanced features, but basically plug 'n play if all you want to do is roll some jams ...

    Guitar Amps are way fun. They break all the rules to make an Audiophile cringe. But Hey, that's Rock and Roll. I'm going for the Sunn 200s / Dynaco MK3 design for a very clean sound in order to gently break my OCD tenancies and work from there.

    I believe my current mild case of OCD is more a result of cabin fever. A week of springlike weather, then got socked with a foot of widow maker snow overnight. I can feel the walls starting to close in .... brrrrrrrr ...

    "Cabin fever" has, of late, been remade into "seasonal affective disorder, and the literature on this grave medical disease makes no reference to "cabin fever" of course. Why? "Cabin fever" by it's name implies a social/environmental basis, not physiological.

    But my own obsession with the improper rampant medicalization of the human condition begins to show through.

    I suggest experimenting with DIY interconnect recipes.  I have had eye opening results with reasonable expense.  For instance, VH audio's fine silver wire recipe for between phono-stage and pre-amp was incredible over my prior DIY cable which I still like in other areas. You can go crazy if you want!

    Crazy, indeed. I've been using some of Paul Laudati's Clear Day Cables silver RCA interconnects (http://www.cleardaycables.com/) between the power amps and preamp with great success and they're not expensive. Also use them in the phono circuit. They're unshielded so you have to route them carefully past the AC lines, but do deliver a loverly sound.

    Maybe I should set about building a full set of DIY. Will investigate VH. Thanks for the advice.

    Heheh.

    No, I meant we're a bit valve-like, ourselves.

    There are some days when I could just use a little extra filament voltage

    Putting all tube gear up for sale. Will buy a little Class D amp (hopefully with volume control), iPod and earbuds. The hell with you lot.

    Death by transistor. I fear the end is near. OTOH, you oughta hear my 6H8Cs in the front Big Bopper driver holes, and antique Sylvanias in the front holes of the preamp. Maybe I will swap out rectifiers with Mullards and do some bi-wiring. I may live another day, Virginia . . .

    I approve of this Sanity by Sylvania. A benefit they never realized, back in the day, their tubes would one day provide.

    I best get me a set for the ST70, and for the pre amp as well.
