Audio Horizons TP 2.0 Preamplifier

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.

Hi fellow TP owners, I've been hung up on the subject of Reverse Polarity. I came across the subject on the soundstage site. It was written revering speaker leads for reversal will change the flow directions and will also affect resisters caps and so on here is the link for interest it's very informative!http://www.soundstage.com/maxdb/maxdb101999.htm

My take on cryo is a conservative one. I chose zero degrees or above as the "safe" area to treat the preamp. No its not full Cyro treatment which reach -300 degrees. Risky without Joseph's approval.

The preamp (tubes included) has so much room inside that it creates its own ice box from all the metal. I have to say the preamp has improved with no adverse effects.

I am grateful to Rx8man for recommending the preamp to me I am forever grateful to Joseph for making it possible to evaluate the TP 2.0.

The improvements are in immediacy and 3-Dimensionality. Voices have realistic character and subtle details are more apparent. This is amazing to me at this stage of the break in period.
