Audio Horizons TP 2.0 Preamplifier

Sherod and Rx8man,
As you know, Joseph has created an upgrade path in the design of the Audio Horizons preamp. To which configuration of the Audio Horizons preamp are you listening? Are you using the TP 2.0nB?

Mine is the n version which has the added noise filter on the power supply and the upgraded Hovland caps. Victor tried to talk me into the balanced mode, but I decided to hold off on that as my monoblocs are unbalanced. I did upgrade the e88cc tubes to Siemens, early 60's, which made a nice improvement.

I have the 'I' version with the noise filter, Hovland caps, upgraded transformers, Siemens falcon logo tubes, but not the extra XLRs.

The 2.0 uses 6DJ8 tubes correct? How many?

Anyone have a tape loop installed?

Tvad,

4 tubes (two per channel) of the 6DJ8 / 6922 / 7308 variety.
