Best Phono Preamp under $300 ?

Cambridge 640P or Musical Fidelity V-LPS.

He already has a Cambridge 640P. Look at his system.

Rootmann would make a great detective! I currently have one & was wondering what else would be good. I like the idea of the Acurus P-10 & Bottlehead also. Thanks for the great responses! The great thing about Audiogon is being able to try a couple of different things & sell what is left over.

Try Vista Audio if MM is all you need. Don't let the size fool you. It plays big. Comes with a trial period too.

I used both Yamaha CX1 & CX2 previously and loved them. Iam not sure which, but I believe the CX2 had a button on the back to switch from MM to MC type phono cartridges. Very quiet and appealing pre. They should be fairly cheap on the used market by now.
Good luck, John
