Clavil, How do you know when you have a speaker controlled "perfectly"?
The truth is you may never hear the true potential of a speaker like the Apogee. Because this is a hard speaker to drive there is no amplifier happy with the Apogee load therefore any amplifier connected to this type of speaker will never sound it's best.
than let's replace perfectly by best possible ;-)
obviously, a strong and stable amplifier at low impedance and with a high damping factor will do a better job than a weak one, and most of tubes or class A ...
considering the budget of our friend your suggestion choice of the Rowland 5 is good one and I am sure he will notice a big improvement
once again: I have been driving my Infinity for 14 years with an David Belles OCM (200 watts) + Treshold pre ... the day I tried Rowland (1000 Watt into 4 Ohms and Damping Factor 1000 at 1 kHz I was just schocked ... I couldn't believe my ears !
I discovered after 14 years how my Infinty can sound !!
