    I know this amp uses the Roy's board, but has lots of mods. I was wondering if anyone has experience of this amp vs a VTA120. Thanks in advance!

    I cannot speak from any experience regarding Don's KT88 amp, but I purchased his preamp over a year ago with zero issues. Don only uses premium parts in his builds and the result is beautiful sounding equipment. I am responding here just to say that you can trust that Don will sell you a quality amp and back up his product with a warranty. You will get better quality parts and sound from his build than purchasing almost any major brand. It is great that Roy and Bob sell amp kits so that we/anyone can build these amps any way to our choosing, but if you like and trust their designs and products but would just prefer to upgrade with some premium tubes, caps, resistors and wiring, you can save a few $ by building yourself or save a lot of time and trust that Don will assemble everything with reasonable labor costs. I have no problem saying that anyone purchasing one of Don's products will be at minimum satisfied with their amp and should have no fear that they are making any mistake with their purchase. At best you will join the many customers of Don that use and love their audio equipment that they purchased from Don.

    Good luck with your decision... Mike

    Thanks, for your response. I would still really love to hear someone's opinion of the Don's vs the a VTA 120 or pair of M-125's. Obviously, pricing on Don's is almost triple a VTA 120, so I would just love to hear the thoughts of someone who has heard both...if that person exists Very Happy I would even be OK hearing someone's assessment on the design differences between the 2.

    We had someone who had one of those apps but unfortunately he’s passed on.
    He had some problems with the auto bias board, after losing a set of tubes worth $1200, Then having another set of tubes taken out he got rid of the Kooteney and went directly to Holger and picked up a couple of his mono blocks I think.

    I have Don preamp and love it.

    PM me for more details.
