Hattor Audio preamps?

I do not own the Hattor but own Arek's Khozmo passive. Excellent passive but definitely prefer the Dave Slagle autofomers!

I purchased a Khozmo preamp a few months ago.  I had been using a 12AU7 tube buffer.  I did not like the volume control.  Not linear but sound was good.  I bought the Khozmo to keep the cost down(vs Hattor)  I have upgraded resistors.  The build quality is superb.  Aesthetically, this is a unique and nice looking piece.  Sound is transparent.  Their equipment is customizable with the intent of unaltered sound.

Arek is very easy to deal with. I emailed Arek and hoped everything was OK in Poland.  He is housing a Ukrainian mom and her child.  What a noble gesture.

I have exchanged several emails with Arek over the last two weeks. He is very responsive and I have no doubt the transaction will be seamless.
