You mentioned with a 16 ohm IMP speaker system, amp consideration is important.@blindjim 16 ohms reduces distortion in all amps. If **high quality** audio is your goal, your amplifier investment is better served by a higher impedance speaker, if that is the only variable.
In what respect?
As I would think an amp with 20wpc > should be enough to push them. Albeit the caveat as usual would be any amp’s voice/performance falling in line with one’s own preffs.
IMO I’d visualize a setup of T3s with 30 or better glass monos, or something akin to one of the Pass labs similar but SS monos.
I forget exactly what JW said when he mentioned they enjoyed power in the ranges of 30 to 60wpc.
Perhaps for the lower end 15 in. Driver to perform best/better?
Only hearing his T1s with your 60wpc monos was impressive. Especially in that immense room, standing well back and far off center as we spoke.
20 watts does work, but a lot depends on the size of your room, how lively it is and your personal listening habits. I found that 20 watts simply wasn't enough- I could run that out of gas. In my old space I used our S-30 amplifier which makes 45 watts into 16 ohms and still felt like the additional power or our M-60s was helpful. If you are running the amp out of gas or even coming close, the distortion will be higher. Its best to have the amp working at a 'moderate loaf', no matter what amp it is.
