The amp will work fine like virtually any other amp that is 20 watts per channel or more. Damping factor is not an issue in choosing an amp. It is measurable but not audible.

Answer ?

It would be a lot more interesting if you could find a power amplifier that just won't work with KEF Q900s so we could point that out.


Finding a amp that won't sound great with Q900s is like going to a grocery store and finding an egg that isn't any good for making scrambled eggs. If you look for broken ones before you buy, it is just about mission impossible.


If you want to figure out how much power you at minimum need we would need to know:


Where in the room you intend to put the speaker (distance from the nearest wall).

How far you intend to sit from it.

What your desires are for peak SPL.


And then you wouldn't even need to tell us anything, you would just proceed to this web page and use it in a self-evident fashion:

Both Arny and I are of the belief that most amplifiers sound the same and that electronics are close to being meaningless in terms of affecting sound quality. Sound quality comes from speakers and the rooms in which they are placed. Sound quality is not a reason to choose an amplifier.

.  all speakers giving different sound with different amps ..

The above is probably due to the way that the listening evaluation was performed.


(1) Level match within +/- 0.1 dB with a voltmeter?


(2) Quick switching under listener's control?


(3) Nobody visible during the evaluation knows what amp is playing at any time?


Fail to control any of the above and I can virtually guarantee that all amps will sound different, even if they are the same amp.

What about a ATI 1802?


As for power amplifier sound, I'm not sure, I've had Audiolab, Arcam, Rotel, NAD, ATI and can't say for sure if there is a difference.

Don't choose speakers just because it has more drivers. Go and have a listen to a pair of £1500 Kef Q and £1500 Kef R and see which one you prefer.


If you can get the Q900 for 50% of price (like I did with Kef Q) then sure...but if I had the choice of say Kef R standmount, versus Kef Q floorstander, I'd choose the Kef R.
