Pro-Ject phono preamps?

Does anyone have experience or opinions on the Pro-Ject phono preamps? I'm interested in possibly getting the solid state RS or the tube DS. I'm a bit torn as I'd like the superior resolution of the RS but would want the lushness and holographic sound tubes offer.

I also considered the Ear 834 but thats a big jump in price. Also, as odd as it may sound, I'm completely downsizing, hence my attraction to the mini sized Pro-Ject line.
If you really want to downsize (the unit is small) and get great sound try a Ray Samuels Nighthawk F=117. New $795, but they show up here used occasionally.
I'm afraid I don't have a lot of experience with different tube buffers, but the one I've read a bit about is the one Grant Fidelity / Yaqin. It's relatively inexpensive and small.
I use the Phonobox 2 and Phonobo 2SE. Both are excellent for the money but I have have two Clearaudio ones.

I think the Pro-ject ones are very competent but not exceptional. The RS offers a lot of flexibility but I went for the 2-box Clearaudio Basic Plus which was more even sounding and a better fit with my Clearaudio tables.

If you are running a Pro-ject tables, the RS is a great choice. Add a nice Ortofon cartridge and play lots of records.
