Amplifier Recommendation for Spendor D9.2 Speakers

of course what @soix says is key and @hilde45's comment is spot on, the speakers are not hard to drive, many many amps will work well from a power output perspective

my personal view is that the spendor d series offers a lively fairly detail oriented sound, so i would err on the side of smooth, very high quality solid state gear (for better bass control) - think pass, hegel, classe, accuphase, ayre and so on

other option is to use stronger tube amps to get a more natural beauty to the music produced by the spendor towers, like better audio research, c-j, bat, vac, the like

better mcintosh could do well too, they have both ss and tube amps obviously, they impart a warmth and richness to the sound at some expense of ultimate resolution

Atma-sphere Class D.

You might like the Circle Labs M200 power amplifier. Here's a thread on Audiogon from other members who own Circle Labs.

Thanks everyone.  I do notice that the speakers seem to fill in at higher volumes, something I did not anticipate.  Would Pass X260.8 or 250.8 do a better job at lower volumes?  

Pass X250.8 is excellent at low volume. Essentially Class A operation
