Phono Preamp Question


I have a Dynavector XX2 MKII cartridge (output voltage 0.28 mV) running through a Fosgate Signature phono preamp. The gain provided by the Fosgate does not appear to be high enough as I must turn volume up very high and that adds noise. Can any of you recommend a phono preamp that provides higher gain for me.
The rest of my system: VPI Aries Extended, ARC Reference 3 preamp, Magico V2 speakers.
Thanks.

"I'm going to roll some tubes in and out of the Fosgate..."

gmsasso-
As stated in the manual,the tube the makes the most audible change is V3(12AX7) 

Changing the other tubes will be very subtle at best. Very subjective. Over time, I've changed all of them including the rectifier, can't say it's "better" just different. The most important factor is installing QUIET tubes.

The Foz also seems to respond to a decent power cord. I also use AC regen(PS Audio Power Plant)

This is an old thread I read when I decided to buy to Foz.

There is some tube rolling discussion. Choice in tube is a YMMV thing and subjective. I tried a few, and presently have a Raytheon Blackplate.

The owners manual also mentions you can try a 12at7 as well in V3http://www.musicdirect.com/documents/pdf/AFOSSIGPHONO.pdf

The tube rolling thing will not help with your low gain concern for your cartridge.
