Peramp suggestions needed

Just looking at whats on A'gon now I see 3 pres I've heard a lot and/or owned that sound good.
1. Belles Audio OCM 55 @ $399
2. Hafler DH 101 @ $125$
3. Hafler 945 tuner-preamp @ 179$

IMHO the best pres available that show up from time to time around 500$are Dynaco modded PAS 3 and Bottleneck Foreplays.

Thanks Schubert I would keep in mind your recommendations. I also keeping an eye on B&K Reference 30 and a Parasound 2100.

There have been many threads about pre-amps. Did you try to do a search? I think you'll find a wealth of material on the topic.
