Audio Horizons TP 2.0 Preamplifier

Sherod. Yes the fellow audiogoner is happy to take the cca's back. But thanks for the tip. Being new to tubes the variety of choices within just the Siemens and Amperex family, pricing, and policies for audition are a bit daunting. But I am just letting the learning curve happen while enjoying the music. My wife has never seen me taking the top on and off so much with a piece of equipment and she is intrigued (have to keep assuring her that it isn't broken and I havent lost my mind. lol)
Grannyring - thank you for the description of the Amperex. I think I will have to listen to some, given I have a fully ss system as well.

Thanks Grannyring, appreciate the input, I will try them.

Joe, just a brief while back I was very "green" about tubes. I learned quite a bit about them in general from reading through the Tube Asylum on the Audio Asylum website. I still go through some of these threads from time to time to refresh my memory. One of the things I found out about tubes is that the best ones, which are usually NOS( but not all) are like a seasoning to the circuitry. It's amazing how so many audiophiles have so many different preferences in sound. Bottom line is what sounds best to you. There is no one best particular tube. IMHO

Yes, I have looked through the tubes threads at Asylum and found them helpful. Victor is very sincere in his conviction that the cc'a's and, short of that, the gray plate Siemens are best in the TP 2.0. And he is very knowledgable and dedicted to the search for "absolute sound" and an expert in the TP 2.0. Yet, from what I hear that the Amperexs can give, they sound intriguing as well. Beside musical perferences (I want to tune my system to awesome classical, though I listen to other genres as well), equipment, and room synergy, you have the personal taste mentioned. Given all this there is plenty of room to experiment. To paraphrase "so many tubes, so little time".

Ahh, the joy and expense of tube rolling...
