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.

Jtwrace,
You have a beautiful, brand new component, made with advanced, top quality parts and materials that many would be ecstatic to have. It's like having a new, super hot girlfriend who turns heads on the street, and asking your friends whether she would be better with DD rather than D. I'd myself would enjoy her first just the beautiful way she was before asking for suggestions about improvements, if ever.

Directly on point here, I recently spoke with a successful tube power amp designer and asked him why he decided to go solid state with his phono preamp for a change. He said he was never fully satisfied with the prototypes, and he added that many of his clients who had great sounding tube phono preamps were nonetheless never fully content with the sound and forever continued searching for even better sounding tubes. He offered this was not for him. Perhaps that's something to think about.
