I too am very pleased with the Tp 2.0 preamp. Joseph Chow is extremely gifted. I have only had the preamp for a little over two weeks, but each day it seems to get better. The clarity, transparency, dynamics, harmonics, tonal balance,timbre,soundstage,presentation of voices,etc. is the best I have ever experienced with any preamp, mostly solid state. I fell in love with the sound of tubes when I was a young man and it looks like I'll stay with tubes now until I'm an old man. The preamp is so revealing that it very easily shows both the weaknesses and strengths of the cables and power cords used with it. I am so pleased with Joseph's work that I'm sending my last tuner to him to have him work his magic on it. This tuner, a Citation 18, was recently modded by a very reputable tuner modifier, and in this version, it pales in comparison to the Citation 14 tuner that Joseph modded for me last month. I'm still undecided on Joseph's power cords. I am having very good results, however, with his budget Premium cord on my tuner. I just got in some older and supposedly better e88cc tubes that I'm going to drop into the preamp for evaluation, but I'm so happy with the present sound that I've procrastinated doing it. Stay tuned for more developments...
