Audio Horizons TP 2.0 Preamplifier

I am leery of the freezer treatment of anything. Freezing is 32 degrees F. I don't know if there is scientific evidence that this temperature is sufficient to change the molecular structure of the item. I know there is evidence of true cryo treatment making changes on a molecular level, but true cryo is substantially lower than standard freezing. There are a couple of threads regarding freezing and double- freezing, wrapping in a plastic bag, etc. but it all seemed ludicrous to me. Maybe freezing does work, but I'm not comfortable enough with trying it out just yet. I have other tweaks in mind that to me would make a bigger difference, in general. YMMV

I agree that freezing at zero is risky at the very best. One can buy a quad of nice Bugle Boy tubes used for $65 and get a warmer more organic sound without any risk of damaging the $3000 amp.

I know that cryo does seem to help the sound as I have done that to a Belles pre, wires and tubes. Zero degress in my home freezer is not cryo however.

This whole thing is most interesting to me to be honest. I am open minded, but must say it sounds very risky to me.

Victor is sending these questions to Joseph but reports that they already cryo some of the components within the preamp. They have not ever cyro'd the whole thing. So - how brave, adventurous is our little club? Perhaps La45 is our pioneer! I would at least check if it voids the wareentee and probably, as an official cyro woose would go tenth instead of second in this grand experiment.

There's some circuit board isolation going in my preamp tomorrow.

I have some other tricks in the making, following my isolation procedure (safe, even better sounding and totally reversible)

Details will follow later upon completion.

Here is the preamp designer, Joseph's response to the cyro idea
"Joseph has gotten back to me and enumerated what hardware in the TP 2.0 he does cryo: The IEC, RCA's, XLR's and tube sockets. He is not comfortable with a complete unit cryo or semi-cryo and doesn't know what affect it would have on the unit in terms of performance or reliability. Each individual would have to decide for himself whether to chance it. More details about the means of semi-cryoing would be appreciated."

We are fascinating creatures. Given how great we think the preamp is and this inspires us to make it even better through tubes and tweaks. But is surely satisfying to start with such a wonderful product.
