Thinking about moving to a tube pre - suggestions.


Hello all,
I currently have a classe ssp-25 preamp, connected to a Hafler 9500 driving B&W DM640s. Sources Oppo 981, and Technics 1200SL TT (Ortofon 2M red) via a Bellari vp-129.

In your 1st hand opinion, would a tube pre w built in phono stage improve the sound from the Bellari / Classe ssp-25?

I'm considering the following..
Mapletree Ultra 4A SE
Quicksilver Full Function Pre

Any other options at similar price ranges are appreciated.

Also I read that tubes should be changed every year or so, because the sound quality decays slowly.

Thanks,

As to the question about tube replacement. Power tubes in amplifiers need to be replaced about once a year, depending on amplifier design and how often you use them. Tubes in preamps often last 3 to 4 years or more, also depening on design and usage.
Elevick: Your right about that..Great all around piece..I owned sp6,8,9,and SP11 for years .Any of the SP6,8,10 or 11 would be great............
There's an SP9 listed right now here. Any first hand experience with it versus the other AR models, and the Mapletree / Quicksilver products?

THanks
