@soix @kalali Yes between the three pre-amps I have heard in my home environment, I like Don Sach's 2 as the best of the 3 , again this is very subjective based on my listening tests and "ears"
Build Quality: better parts, point to point wiring , to me DS 2 is very revealing, no brightness, realism in voices, vocals are good , bass is just about right ! do not hear any tube sloppiness sometimes you get with lower class pre amps, very quite. However the unit is not cheap but considering the fact it competes with higher priced units and is custom built it is perhaps fairly priced at its price point . Hope that helps.
