Zesto Andros PS-1 Tubes

If you actually own the Andros, I believe you must have just purchased it as I remember you considering it in a recent post. If so, why not try to enjoy it with its stock tubes? It's a $4,000 piece of equipment and every single review has been very positive, if not exulting. I don't quite get the urge to change sonic character of components off the bat.

Yes, I have put in 1 set of NOS tubes which are Seimens ecc83 from the 1960's which made for a more airy detailed presentation.I my try a full set of Telefunken's with the diamond emblem on the front at a later date.

I really like the sound of the Zesto Andros. It was ggod with the stock tubes, however, I prefer the sound with the 2 matched Seimens tubes.

Yes, I actually do own the Andros. I simply asked a question for owners that have tried it and what their results were.

Moonguy-
Thanks and keep us posted.

Is this the model which uses 12AU7s and 12AX7s? There has been a lot written in general about rolling those 2.
If it's the Phono Stage then certain commonly tried substitutions may not work. The switch I am thinking of in particular is using in 5751s instead of the stock 12AX7s. In a Phono stage, the loss of gain using 5751s may not be desirable. That does not preclude many other common rolls. If you like your sound clean and strong then vintage Telefunkens might sound good. If you want a rich full sound then older Mullards might do the trick, but they are getting truly scarce. The current production Gold Lion 12AX7s have been prized for their rich full sound.
A really special 12AU7 sub are the uber expensive Amperex Heerlen production 7316s. The Stock tubes are pretty good BTW they seem to like the current JJ803S replica, for their 12AX7.
