Martin Logan Summit and Classical music.........

If your dad likes dynamic impact and energy in classical, then the ML would be borderline -- so yes, it's worth auditioning.

I.e., did your dad LIKE your Innersound "ribbon" sound?

Absolutely would have him audition them, BUT, be forewarned their placement needs a fair bit of tweaking to get the most out of them... lots of breathing room (at least 3-4 ft from front wall and 2 ft from side walls), plus need to experiment with toe-in and front tilt/rake angle. With 400 watts of ice-powered woofers per side, the Summits are a new breed of ML. I mainly listen to acoustic and jazz, with some classical thrown in. Everything sounds FANTASTIC.

Thanks as always for the info!

As the owner of the very first set of "Monoliths" and the Clarity, I would give serious consideration to a set of used Quests. In my opinion they ar perhaps the best value ever produced by Martin Logan! They have a very wide and deep soundstage and excelent tight bass.

Summits are great with classical music.. great timber and great coherence. The beauty of the Summits is the fact that most of the fundamental frequencies and the remainder of the harmonic frequencies are all taken cared of by a single transducer.

Pair the Summits with a good tube preamp and a solid Class A amplifier/tube amp, position correctly, get a good source and you're on your way to world-class sound!

Absolutely recommend the Summits!!!
