Tubes or stick with S/S


Right now I have some Cornwall III's that I am happy with. Driven with an McIntosh MC 7106 that works quit well. I am kicking around the idea of buying a PrimaLuna integrated amp, any suggestions? And replacing the McIntosh.

Manley Mahi Mahi monoblocks.  Beautiful sounding, quick as hell with great imaging and natural timbre.  Vocals and acoustic instruments sing.  Can be found for about 2K used.
Several customers of ours have commented to us that our M-60s make the Tannoys sound the best of any amplifier they've tried. I get these comments but its rare that they tell me what the other amps are. It does appear though that if the amplifier is low distortion that the speaker benefits from having more power. When the power is clean it does not sound loud- IMO/IME that is a sign of a really good system.
If I had a pair of the K-horns, only one place I would be looking for an amp....one of Dennis Had's Inspire Single ended KT88 amps...they work great with efficient speakers.
Go with tubed OTLs with higher power. 30W per channel as a minimum. In my experience, OTLs are in another league when you compare them against SET and push-pull designs on higher impedance speakers. 
I have come to the conclusion the best compromise is to use Tube and Solid State in combination. Tubes for Pre-amp, and  Tubes for Power Mid range and Highs, and Solid State for Bass. This can be achieved by bi amp or Sub-woofer. I prefer Sub-woofers. I would recommend SET amp. There is no right answer - I guess.
