I am used to it, actually rolled two preamps in as well, the Hovland has a certain charm, a certain naturalness that I have not heard with other gear I have tried.
Nervosa? Nah, I needed a preamp because I had none, I sold mine to buy a Micro Seiki turntable, (best purchase to date)!
If you can't hear the difference between tubes within a day, then you should switch hobbies
When the right combo comes you know it, you don't wait for it to come on its own, you have to make it happen, eventually you will find the right combo.
Ok off to find some Mullards..................
thanks guys
