Which Amp for uppermost freq' in tri-amped setup?

I need to choose an amp for the upper frequency range in
my tri-amped system, and I may be making this decision more
complex than I need to. Crossover frequencies will be 150Hz
and about 4000Hz. I have two Marchand crossovers (XM-9),
two NAD 2600a amps for the woofers, and a Linn 5105 amp
for the mids. (I may only use one of the NAD's, but could
run two in mono if desired.) So,the amp requirements for
the top end should be easy to satisfy, no? High wattage
or current flow should not be necessary. I would think
low distortion up to, say, 50KHz should be a more important spec.
I'm leaning toward a Linn LK85. I know this is an
unusual question; I sincerely welcome your suggestions and
comments.

There was a Spectral DMA 50 offered here the other day for a reasonable price. I find it an ideal amp for the high end of the musical spectrum. It does not necessarily have to be run with MIT wires. Just an idea. Cheers,

Try a Pass Aleph 3 or equivalent Volksamp.

If you get an LK 85, use that on the mids and use the 5105 for the tweeters, sounds backwards, but Linn is fanatical about using the best amp on the tweeters. The 5105's a great amp, have you given any thought to buying another one of those?? Or two and selling the NAD's? You might find it easier to set up and use with all matching amps.

Just my .02, I run 6 of the 5105's in my system, hell I even have a spare one I was going to sell, but decided to keep in case one of the other ones fail. These should start to show up used more frequently now that they are discontinued.
