What better to power my 82db Magico Q5

If it were me, if size, weight, power consumption or overall cost of ownership over time are factors at all, I'd be looking for a Class D amp that can double down to 4 and 2 ohms best. There may be a general correlation between this and current delivery capability but I would not go on current delivery specs alone.

Then of course, how loud you need to go will determine how much power is needed as well along with all the rest and also most likely how much the right amp will cost in the end.

BTW the sound of my system these days on all my speakers running off teh Class D Bel Canto ref1000m monoblocksreminds me a lot of teh sound I heard a few years back for reference with Magico Mini II driven by VAC amps and DCS digital source in a smaller dealer showroom. Very liquid sounding midrange, good dynamics and detail without being etched and excellent 3-D soundstage and imaging. Only higher output levels of the same possible as well even in my largest room as needed. I used other SS amps prior. The BC Class Ds have a lot to do with this "signature sound"
