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,
alex333
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
Alex333 : The SP9 in my opinion would be a "Bad" mistake..The SP 9 in my opinion are threadbare and very lean sounding...This would not be the direction you asked about...An Audio Rsearch SP 6,8,10 or 11 is a whole different story...
Thorman, Thanks so much for your input.

Still wondering abour the mapletree or quicksilver options.

Regards,
How many Mapletree preamps have you seen on used market????
There is your answer.
The lack of any product for sale on Audiogon can be due to a number of reasons that may or may nor have anything to do with quality of a product or its popularity.

An item may sell only a handful of units in a given year, making the pool of available used units very small. Also, some products are sold primarily through word of mouth or through non-internet channels. Doshi preamps are an example that come immediately to mind.

Also, owners of a given item might not be frequent users of Audiogon. For example, I can think of certain manufacturers that have a much more avid following on AudioCircle, and therefore used examples of their products will be found more often on AudioCircle.
