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 agree with the Rogue ST-100 recommendation especially with Gold Lion KT-77 tubes for 70 wpc.  Also suggest you not take speaker manufactures specs at face value as they have been known to fudge them quite a bit.  For example my Spatial M3 TM's have a stated efficiency  93 db until you look at the fine print a see that that is only over 300 hz as it's twin 15 inch woofers are no where close to 93 db efficient.
I had been happy with Rogue Cronus Magnum II for 6 years.

With tube rolling it is a very good amplifier.

ST100 is very similar to  Cronus Magnum II.
Mike Sanders of QuickSilver uses JBL horns with woofers I think they are at least 10 " woofers ( 4 in each speaker unit). I have QuickSilver mono 60 and just love them or  if money is no object you can go for the EAR 509  mono or Viva Solista 18 watt Set integrated amplifier , my speakers are 97.5 efficient Daedalus Poseidon
