Drummers! Which amps do you use for best Timing & Dynamics?


Many audio systems fail to deliver a really tight groove with correct dynamics and rock solid timing. The timing must be coherent from lows to highs as well. Some amps time well in the mids but lag behind in the bass. The amp must be lush or free of any hardness at the same time as well.

Please share your choices for amps , sources and speakers. 

In my case I am looking for great low volume performance, huge soundstage that opens up in direction to the listener, and the tight groove of course. Speaker efficiency 88db, minimum impedance 3Ohm.

I have the impression that amps which double into 4 ohm, have zero negative feedback and have high idle power consumption are the best for high current low volume performance.

I also prefer single solid core cables for best timing.

Price up to 5k used.

As bang for buck reference I want to mention the Kinki EX M1 integrated or M7 power amp which has excellent low volume performance and timing. It is slightly lean, cool mechanical and I am interested in other alternatives ( neutral or warm)

For the Magnepans I run  Classe CAM350 Monoblocks.  On the Acoustat Spectra's,  Acoustat TNT200's Monoblocks 
I had Maggie 3.5Rs but my room is volumetrically large. I added 2 SVS powered subs (Ultra & Plus) attempting to get them to blend I went through 3 Beringer and one DBX crap active XOs. I couldn’t afford a high price XLR active XO.

Current speakers are Emerald Physics 3.4s, which are open baffle 12" concentric drivers with 1" polyester tweeters. After going through a number of class D amps, including a EVS 1200 based on dual mono IceEdge AS 1200 modules, which took me closer to what I need. Then I got a LSA Voyager at 350/600, surprisingly it sounds much more powerful (and continuous) than the EVS1200, which is twice the wpc. What does this have to do with clean bass...

Emerald Physics also made a 2.8s which uses the 3.4 mid driver and 2 @ 15" carbon fiber woofers. I expect they will bring fast and powerful bass
If you're looking for the best natural sound setup for drums, you need to go Planar, as in Magnepan. No other type of speaker can compete with the speed and transparency of a Planar speaker.
Planars with permanent magnets won't be as fast as a driver with a field coil. This is because as current is applied to the voice coil, the magnetic field of the permanent magnets sags a bit. This causes the diaphragm to slow down.
