Give the AVA Vision a try. Nothing to lose with a 30 day money back guaranty.
There are some nice preamps on Audiogon right now but they will have more than your basic inputs which will be difficult to find.
There is an ARC LS9, Cary Audio SL100, Primare Pre 30, PS Audio GCP-200 and a couple of Krells for sale on Audiogon. All very good SS preamps
