Rather than do a new post, I’ll join the thread here as I recently bought a used, but ordered at the end of 2023, Hattor Big dual mono active/passive preamp. It has the AMRG resistors and New Class D opamp. Top of the line stuff based on my limited knowledge of the techie stuff. The remote controls every function. It’s solid and beautifully made like the main chassis and smaller, external power supply. My guess is very limited use on this piece and it’s sounding a bit better each day.
As is usual for me, I just play music and let my brain assimilate things over time. The Khozmo attenuator is more revealing than the Alps Blue Velevt pot in my beloved Supratek Chardonnay tube preamp. The Chardonnay has been under the weather for a couple of months now, first with a silent left channel and now with both channels being mum. It is under warranty, but there’s a part of me that wants to have a Khozmo 64 step attenuator installed. I have yet to find a very good tech who’ll look at it. And yes, that would wipe out future warranty service. So I’m just pondering at the moment and continuing to appreciate this very fine Hattor.
The Hattor sounds, full, rich, natural, very revealing, but not quite as airy and holographic as the Supratek. But it’s an apples and oranges comparison as I’m not A/Bing the same music. Arek at Khozmo/Hattor is a sole proprietor and also makes a tube buffer to mate with the Hattor Big. That would really be fun to listen to as well.
I’m listening without subs and just keeping things as simple as possible for right now 🎶
