phono pre amp giant killer?


I'm in the market for a used phono pre amp. I'm considering the pro-ject tube box II and the clear audio nano (because of some positive reviews and the fact that I use a Clear audio Vertuoso Wood Cartridge). My question is how much do you need to spend on a used phono pre amp in order to get to the level of truly top flight performance? My budget was going to be 350 but that may change with this thread.

thanks

I'll echo Stanwal on the Dynavector P75. Unbeatable for the money, both for sound quality and flexibility.
Gram Slee Era Gold mkV - a little above your price range on the used market at ~$450, but I owned it and compared it with a few other phonos in the $1.5k-2.5k range(new) and it held it's own.
Thanks for the advice on the Dynavector p75 and the Gram Slee Era Gold mk v. I'll be looking into those.
I don't know if there's still one up for sale here, but the phono stage in the Klyne SK-5A is a very nice one indeed and the whole preamp is a find at its going price of around USD$1200.
