What separate tube phono stage do you use ?

Agree with Chip on the Eastern Electric (sadly available only on the used market AFAIK).  I've owned mine for more than 15 years, fitted with NOS (circa 1960)  Mullards, and it is in use almost every day.  Great sound and (knock on wood) no problems. 

Allnic H-3000, new model is H-7000 I believe. Excellent phonostage.

Bottlehead Eros. It's awesome if you're willing to do the work.

At the price level the OP suggested I would consider the TRON Convergence. Fantastic unit that punches way above its' asking price imo..
