What good tube preamp match for hafler 220 amp?

I use to sell these and I don't remember them being very demanding in pre choice. I would think any good tube would work fine. If you see a rebuilt PAS3 Dynaco that might be good as Dave Hafler designed that as well. Otherwise I would look at older models from established companies like CJ or AR. Smaller companies like Blue Circle make good ones also. I would look for the best bargain if I didn't have a specific sound in mind. The matching Hafler 101 was a good pre for its time although it is SS.

Might want to take a look at the Quicksilver line

When I had a Hafler DH-220 it was paired with a stock McCormack TLC-1. It was a very sweet sounding combination that I liked very much. I don't know if budget is a factor but the cost of a used TLC-1 is probably more than double the cost of a used stock Hafler DH-220 right now.

Thanks for your suggestions.I do have a Quicksilver L/S mated to a McCormack modded .05 amp with a Rega apollo.The Q/S was modded by RHBdezigns.The sound is divine and has converted me to tube sound,therefor wanting tube warmth sound in 2nd system.Thx
