I have one that’s got all the upgrades and the tube stage as well. It’s a superb preamp for sure. In my system, the tube stage adds a lot to the sound being amazing. I recently compared to the Benchmark and there was no comparison, the Hattor is worlds better. This piece oozes quality and sounds incredible.
Hattor Audio preamps?
Got my eye on one of these. And yes, my system is passive friendly. I've had resistor based passives before, as well as transformer, autoformer and LDR preamps. So I know I like the sound quality which can be had with a passive. Anyone out there have any experience with the Hattor stuff?
