I have spent decades as a hardcore audiophile. Have had at least 15 preamps and that number or more amps ranging from solid state, class D, hybrids, and tubes. I peruse these threads all of the time which is how I found out about Sachs preamp which I have in my main system. The reports of the Sonics from the Supratek preamps is also quite impressive. Sachs and Supratek both sound like they have disruptive products that audiophiles will hear and ask themselves., why should I spend more. In my exercise room I have the even cheaper Schilling preamp that is quite good.
I often have my equipment modded so the internal layout is important to my modder. I have no desire to mod the Sachs preamp as it sounds phenomenal. Since I have the audiophile disease in a bad way, I want to try one of the Supratek preamps and possibly one of the dehavilland preamps just for comparison. However, I dont give a rat's ass about the internal aesthetics of the gear when considering these purchases.
I am a sensible audiophile. This descriptor though is probably an oxymoron lol. I would hate to be a manufacturer of high end preamps going up against the three (two of which I own) previously mentioned preamps. Just my two cents from a non-insider...
