5-27-14: B_limoAren't the Line Magnetic models integrated amplifiers? It appears that B_limo is looking for a power amp, to use in conjunction with his Lightspeed attenuator.
... it's time to start researching tube amps in the $1500 price range.
I'm looking for something that looks good, has more power than my Prima Luna 5, and has that charecteristic warm, lush, textured and detailed sound.

LM Audio 211 or 219. The former uses EL34, the latter KT88!
Also, I believe "219" should be "216," with both model numbers being followed by the letters "IA." And neither meets the stated criterion of being more powerful than the Primaluna Prologue Five.
Finally, I'm not sure that a tube amp would be an optimal choice for use with the particular speakers. If the speakers are the same model or have an impedance curve similar to that of the Paradigm Reference Signature S2 (see the first figure) the interaction of their impedance characteristics with the relatively high output impedance of most tube amps will result in an over-emphasis of the 1 to 2 kHz area, and an under-emphasis of the mid-bass, assuming (as I suspect) that the speakers were designed with solid state amplification in mind.
