Hattor Audio Autoformer Reference Preamplifier


Hattor Audio is now offering a Reference Preamplifier using autoformer attenuation (link) instead of resistors.  Think Slagle, EM/IA, and Pal Nagy's icOn.

I have successfully used their flagship, The Big Preamplifier, in passive mode to provide volume control for my system.  The Big Preamp has both RCA and XLR inputs and outputs, an outboard  power supply, a large display, and remote control of power, inputs, display brightness, mute, passive/active operation, adjustable gain, and volume for each channel (i.e., allowing control of balance).

The new autoformer based reference preamp is priced reasonably like all Hattor gear, and offers four autoformers for the balanced version.  Either copper or silver autoformers are available, but the silver version more or less doubles the price.

Anyone here tried one yet?

Hey mitch2,

It’s interesting that you made this post. I just recently inquired about setting up a review for Stereo Times on the Hattor silver version of this preamplifier. If they are interested and set up the review with me I will have the information you are seeking

Hey Teajay, thanks for reaching out. I purchased the copper version and it is currently being built.  I didn’t choose copper particularly because of the price difference but because I have not read overwhelming consensus that silver is better wrt AVCs.

Arek knows me as a long-time customer so, if you are game, maybe we could ask him if we could swap units after your review and then we could both directly compare the silver and copper versions.  We could even schedule the hand-offs so that each of us would have both units in our houses at the same time for a week.  It would require him to treat both units as demo models and I would commit to either staying with the copper version that I already purchased, or sending it back and upgrading to a silver version, either the demo unit if you don’t buy it, or  a new unit. Of course, I would do Audiogon write-ups on both and the comparison.  Let me know if that sounds interesting to you and, if yes, we can reach out to Arek.

@mitch2 I also run the Hattor The Big Preamplifier and am looking forward to your comparison with the new autoformer pre. Also would like to hear your experience with how The Big Pre has compared to other brands.
