Best sounding phono preamp under $600

Hi Bob,
re the Musical Fidelity - I ran one of these for years, added the X-PSU and was stunned by the difference.
Asked long and hard on here re thoughts on Phonomena vs. Camelot - varied opinions as one would expect.
Just occured that buying a stage that has the option of a power supply upgrade at a future date has to be a sensible idea as every time I have went this route, the improvements far out stripped my expectations.
I think any review you read be it Musical Fidelity, Musical Surroundings, Channel Islands, Creek and all, will say the same thing.
Happy Trails

Simon - thanks for your comments; there's obviously several good phono preamps in the $600 range and lots of opinions on which one is the best. I've seen the Musical Surroundings Phonomena mentioned quite a bit and will probably give it a listen.

Bob, I was using the standard walwart with the Phonomena. The fellow I bought it from owned the battery power supply at one point in time. He said the sound improvement was subtle at best and, in his opinion, wasn't worth $600. I don't think you can go wrong with the Phonomena. It's much better sounding than the X-LPS, in my opinion. Good luck on your decision. Best, Mark

Thanks Mark; I don't think I'll bother with the battery power supply for the Phonomena.
