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?



No apology necessary.  Just wanted you to understand that what I hear in my system could be very different than what somebody hears in a system using low-powered tube amps with high efficiency speakers. 

I loved my Hattor passive The Big (dual mono), but sold it as I got a great deal on a Audio Alchemy DDP -1, dac/pre (see Absolute Sound review (March 2016. Later I purchased the optional PS 5 outboard PZ which is an amazing addition

FYI: Hattor offers a input board for it

I own 3 of his KHOZMO DUAL MONO and I own 2 of his HATTOR WITH ACTIVE AND PASSIVE CHASSIS HE CALLS IT the big HATTOR preamp with the full on best packages on both active and passive….I Took it one giant step forward  and replaced all the capacitors in the active with DUELUND and I really cannot express in words the level I’m at now ….the 25K level…..that’s all ill  say…..you will have to raise the roof on the active to accommodate the duelunds but it’s easy just get longer screws and spacers and you don’t even notice it when on shelf….TELEFUNKEN TUBES ARE AWESOME IN IT ALSO…IF YOU DONT feel,like raising the roof the next best musically is the V-caps CuTF CAPS THEY JUST TAKE LONGER to break in if you don’t believe duelund or v- cap are the best ….well….. that’s ok …..

Hi   I'm confused as to the differences between the Khozmo and Hattor passive peamps - is there a simple answer? :-)



"- is there a simple answer?"

Sort of. Two companies run by the same guy (Arek Kallas) from Warsaw Poland, offering a couple of different types of discrete resistor volume controls, but Hattor has the more upscale, complex products with better looking casework while Khozmo offers more simplistic solutions, at lower prices, in more basic looking casework.

Because Arek will customize the builds from either company, you really can have it your way. I use a Khozmo volume control in my main system, but it is made from two separate volume controls (i.e., dual mono operation), has a display and full remote control of L/R volume and mute, plus on/off and display illumination. The attenuators are Hattor/Khozmo’s best using Amtrans AMRG resistors. It is in a Khozmo metal/wood case and has no switching, only a single balanced input and a single balanced output with Furutech connectors.

So, it is a very well made Khozmo badged unit but also very simplistic and in modest but nice-looking casework. The sole purpose is to passively control the volume ahead of a unity-gain, solid-state buffer that feeds my amps, and to allow me to remotely operate volume/balance/mute for my system and to see the result on an easy-to-read display. I also own two Hatter "The Big" preamps, which are very nice sounding units with much more functionality than my Khozmo by providing various single-ended and balanced inputs and outputs, and both passive or active operation with switchable gain from 3 to 9 dB. I used to own their Tube Buffer, which was very nice sounding as well.
