highest damping factor amp

Perhaps the best little woofer amp ever made is the Electron Kinetics Eagle 2.

I didn't know the Aleph 3 had a very high damping factor. What is it?

Don't know the damping factor of the Aleph 3, it's just a high quality small SS amp. Other's to consider: Bedini 25/25; BEL 1001; Bryston 2b; ????? I like the Eagle 2 idea, thanks. There's a new amp from JOB that's TINY in size physically and 50 watts.

damping result 2711the k2 is now intalled on the subs side with the terminals close to the driver terminals

You don't need a high damping factor to control TAD woofers. My amp has a very low damping factor and works great with the dual TAD 15" woofers (1602s) in my system. Now they are in series for a 16 ohm load, so nearly anything can drive them. And they are very satisfying as they go to 20Hz in my system :)
If you wire them in parallel, **any** solid state amp that can make a few watts and many tube amps will drive them just fine.

Now if you over damp them by using an amplifier with a very high damping factor, you'll actually get less bass and no definition. There aren't any speakers out there that really need more than about 20:1 damping factor. IOW, the damping factor thing is a bit over-rated. What you really need is the amp's ability to make power, and with the efficiency of the TADs, that really isn't all that hard.
