No one was more amazed than myself at the performance of the TP 2.0. The noise floor was much lower, channel separation better, soundstage wider and deeper, bass punchier than my previous preamp. There was a humanity to the music that few other components in my experience can achieve. In fact, the measured specs rival those of many high-end solid state preamps. Truly remarkable since the 2.0 employs vacuum tubes. As to the tubes, I had purchased several matched pairs of NOS Siemens E188CC gold pins several years ago to use in my previous preamp. I am using them in the 2.0. I also have the EH 6922's that come with the preamp, and really they are pretty good. I'm not sure I would ever again spend the exhorbitant amount some of these NOS tubes are commanding these days. As to power cords, I am using Joseph's Transparency cords exclusively in my system. They replaced some very highly regarded power cords. Please e-mail me privately and I'll identify which ones. For the record, I am merely an enthusiatic fan of Joseph and his products. I try to promote his efforts whenever I can, but receive no compensation whatsoever other than a hearty "thank you". I am constantly amazed at the level of performance he achieves at relatively modest prices, and he and Victor are completely straightforward people to deal with.
