Thanks Sherod and Rxman for being pioneers on these units. It will be another week before I get my DAC back (having it modded by Mauimods, then will get system up and running and be ready to explore new things with the AH 
Anyone going to see Loreena McKennitt?
In Asheville we are paying 49.50 for premium seats for her concert, so I guess location matters

To me the tube changes are to fine-tune the preamp to one's musical preference, room, and equipment. I could be very very happy with the preamp with the stock EH or Siemens provided, but it is fun to see what other sounds can be experienced.

I received four matched Amperex 7308 White Lable PQ's today. Initial listen is wonderful. Best I can describe they seem a bit wetter and warmer than the Sieman gold pins (provided as TP upgrade) with a nice sound stage and localization of instrume...

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-c...

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 woul...
