don sach's custom kt88 tube amp

Guys,

I received my modified DS2 last week with Don’s latest Polish made Deulund copy oil caps and 6BY5 rectifier and it sounds amazing! I am hearing more transparency, better sound staging and imaging, more depth, lower floor noise, more air/ambiance. Bass is tighter, midrange is purer/more organic but you are going to be knocked over by its ”HOLOGRAPHIC” presentation; sounds emanating beyond the boundaries of my loudspeakers…

It is astonishing how you are immersed into the music with Don’s DS2 Tube Pre; his original DS2 is Amazing but the updated version is “UNBELIEVABLE”! For those of you who are in the market for a new pre-amp, I highly recommend that you put this pre on your short list. If you already own one of Don’s creations, get this updated version done ASAP!

I am not aware of any mods that can radically change the sound of a system for a very small investment. Act now and get your units in or orders placed soon…

Gents,
I have been using Don's amp in my system for a few months, but with the advent of the 100+ degree weather here in CA, I swapped back my excellent McCormack SS amp into my system to ease the burden on my air-conditioning load, as any KT88-based amp generates a lot of heat.  
OMG, the magic is now gone in my system. Don's amp is infinitely more musical and revealing, with a far greater sense of realism with the music.  It is a night and day difference.  

Just spent the last hour catching up on this thread, and AudioCircle, and dsachsconsulting.com
Sounds like the real deal. 

I would love to try his pre and amp.  Keep it coming folks! I'm enjoying hearing about your experiences.  

Any more updates on people's experiences with Don's amp and/or preamp? I have had the preamp for about three weeks now, and will take delivery of the amp a week from Monday. It has shipped, but now has to travel cross country. Needless to say, I'm really looking forward to hearing how they sound together.
