tube phono stage upgrade


Looking to upgrade my Project SE II Tube box as I think this is the week link in the chain. Currently using;
1-Wright AU-1000 preamp
2-2a3 Power Amp
3-Thorens TD-124 TT
4-Klipsch Heresy HBR

Any suggestions in the 1000-1500 dollar range used?

Thanks Bachtovinyl. I am a little confused as you state that the AU-1000 is a phono amp. Mine is not, it is a preamp with no phono input. That is why I have the Project phono amp. I am still leaning toward a tube based phono amp which would have options in mm and mc.
Fromunda: My apology! I typed in AU when I should have typed AG-1000 which is the phono-pre-amp. My offer still stands. Rob.
What is your offer exactly? Im in SF Bay Area(Home of the World Champion Giants!!)
