Speaker choice for 50w push-pull tube integrated


I have a Graaf GM50 tube integrated paired with relatively inefficient Sonus Faber Cremona Auditors (88db, 4ohm), and may begin to look for a more full-range speaker with an efficiency rating better matched to the amp (maybe 90db, 8ohm). My budget is $6,000 or less--used would be fine.

Does anyone have a suggestion for speakers that would be a synergistic match with the 50w push-pull Graaf? My system fires across the short dimension of an 11" x 30" room.

Thanks in advance for your input.

Totem Forests with 50 watts?
I ran them with 200 and they sounded good.
I don't think 50 will cut it.

Jaibo-
Have you ever heard the Graaf GM50b integrated? Not sure how you can make your assumption without having heard it first.

On the other hand, I know what you mean about Sonus Faber. I started listening to my girlfriend's Minuettos, bought a pair of Signums (which I just loved), then eventually, after trying lots of other stuff, tried the Cremona Auditors with an REL Strata III sub. I may just move up to the Cremonas or keep what I have. Just thought there may be a better synergy out there somewhere.

Everybody--many thanks for your replies. You ought to check out the Graaf equipment though. The integrated is a very special piece.
