I haven’t heard the Don Sachs but it looks nice plus he’ll work with you on upgrades to my understanding, a big plus. I have lived with a 6SN7 based output tube preamp up to a few years ago, still have it but it doesn’t hold a candle to my Bill Thalmann upgraded Vintage CJ PV9a in any parameter of performance. The Classic 2 SE with the teflon caps used, no longer available new is killer for the money and beyond but no remote, definitely worthy of consideration.
Tube Preamps.....
I am running 2 GFA 565 Musical Comcepts modded Amps with Vandersteen 2ce v2. I am looking for a good quality tube preamp. With or without a built in dac. Should I stick with shopping for a used Mac? Or should I look at others also. Suggestions? Like to keep it under $3000. Could stretch to 3500. Thanks for your input.
