Tube amplifier suggestion for 101 dB speakers


Hello All,

I've been using the Tyler Acoustics PD30s with Classé Sigma solid state preamp and amp combination.
These speakers have two 15" woofers and a horn tweeter, 4 ohm, sensitivity 101 dB.
The above combination is not the best, especially for complex rock music, the highs start to distort, they are harsh, just bad. Never had tube gears, but after reading a bit, these speakers apparently scream for tubes. Actually somebody brought over a hobbyist-made tube amp and yes, the speakers were tamed.
I'm willing to switch to a tube amp but prefer to keep the ss preamp.
Can anybody recommend a few good tube amp matches here, for a max of 3K new or used. Room is just a good medium size. I want something that I can keep for many years if possible and being somehow flexible to tube rolling.

Thanks.

I have a friend who drives his Klipsch Cornwalls using a pair of SET monoblocs with I think somewhere around 12wpc and they sound glorious and can handle loud classical orchestral music passages with ease in a relatively large room. They sound particularly engaging when we listen to more intimate venues and instrumental music like jazz trios and/or music with vocals. He also has a Pass XA30.5 and we both prefer the lower powered SETs even though the Pass has a slightly better bass definition particularly on tougher orchestral content. I would have probably been quite happy with the Pass had I not heard them side by side.

Have you thought of a tube preamp or buffer before you give up the Classe amp?
You mentioned that you'd like to keep the ss pre, however I'm going to recommend that you try a tube preamp for a couple reasons. The preamp tubes can and will tame the treble. Preamp tubes generally live much longer. And lastly, rolling preamp tubes is MUCH more feasible, for example there are basically no nos 6550( a popular power tube) tubes left anywhere, whereas even the most sought after preamp tubes are available.
