Hi Pdreher,
I had on hand a set of NOS Amperex 6922 Mirror Matched very low microphonic tubes from Andy that I had been using in a phono stage till I sold it. So they went in the 6922 position. Now it was time to replace the stock 12AX7 tubes. Two recommendations from Andy. Either some matched low noise Amperex or Telefunkens. I could have Amperex tubes and sound all the way through which Andy said you absolutely could not go wrong. Or use the Telefunkens which did all the same good things that the Amperex does but has a certain vividness to them. Andy was able to assure me that the vividness did not equate to brightness which I knew I would not like. More like a bit of life to the music. Andy said he can not prefer one over the other so he goes back and forth and back and forth over the two and enjoys them both equally. I settled on the Telefunkens to start and they are excellant. I also will be getting the Amperexes too at some point. I would enjoy comparing the two and using them to enjoy the music. Andy also applauded the purchase of the Calypso and felt that with good NOS tubes it performs and competes at a level soo much higher. Also I am new at posting and noticed that "system" can appear with posts. This can be useful when asking advice. How do you have "system" appear with a post?
