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?



I just wanted to update this thread. I received my preamp about a week after ordering it. Working with Arek was a pleasure. It is extremely well constructed and solid. When you factor in the quality build and the flight case it ships in, you can understand he’s not getting rich at this.

It is very transparent as you might expect, but dynamic as hell too. Just gets out of the way and let’s your amp do it’s thing, which is exactly what I wanted. Highly recommended.

I still own two of the Big Preamps and more recently had Arek make a custom Khozmo dual-mono passive using his best Amtrans AMRG resistors and volume control from the Hattor, upgraded connectors, and only a single input and output (i.e., no switching) that I use to remote control the volume and provide a display into my solid state, unity-gain buffer.

The Big Preamp is IMO hard to beat for the money and for what you get wrt the volume control, remote, display, balance, connectivity (RCA and XLR), flexibility (i.e., passive vs. active with variable/switchable gain), and of course sound quality.  I also owned the Hattor Tube Active Stage, which is quite nice as an option to their op-amp active stage (my Hattor preamps have the NewClassD op-amps).

Do you have specific questions?
