The best speaker you ever heard?
The best sound I've heard was from a dealer system in Plano, TX featuring JMlab Grande Utopia speakers driven by Levinson and Wadia electronics. This would have been in the late 90's I believe. I haven't heard any uber exotic systems lately so tha... 
Recommendations for a "summer" amp?

W7 to answer your question, I have some tube preamps (Audio Research LS-16mkII and Cary SLP-98 F1) and an older Forte solid state preamp that I rotate in an out. The Forte provides by far superior bass performance over the tube units, and I am sur... 
Pre amp for Pass Labs XA30.5 – Tube or SS
I've tried both SS and tube preamps with my X250.5 and I believe I prefer the solid state for the better bass quality. The x250.5 does bass so well that it's a shame to not have a preamp that can do it justice in this department. Depends on your m...

ARC LS25 with PASS X250 - bad match? Seems bright.
Did Marktomaras ever come back with his comparisons? I would like to know how it turned out. 
Affordable SS amp that has tube characteristics
In listening tests by Stereophile golden ears, a prototype of what would become the Carver M-1.0t production model was found to be sonically indistinguishable from the Conrad-Johnson Premier Four tube amp. I don't see how you could get any closer ...
