SET shortlist to drive tweeters in active system


Hello.

I'm building a DIY 4-way active system and thinking an SET for the tweeters might be a great choice. But wanted to get input from knowledgeable users.

The 20 to 600Hz range will be handled by active subs plus 10" drivers with their own 700W class D amp.
I'm still undecided about the midrange driver, but likely to be driven by my McIntosh MC275. It will be a 6.5 or 8" cone, though.

The top end will be through a Beyma TPL-150H, a pro ribbon with a horn playing from 2 to 23 kHz, spec'd as 102 dB (@1W, 1m) and a pretty constant impedance of 4.9 to 5 ohm.
I'm thinking it looks like a great place to use a SET, right? Which amps should I include in my shortlist?
Looking for SET holographic magic with dynamics.
The signal will come from a balanced IC, so XLR input would be preferred.
Reliability is a must, and the more the better. I will import this into Argentina, so sending the unit to the manufacturer would be difficult.
Price range: under 4k.

Thanks!

I don't see it mentioned but you will probably need some kind of external active crossover to get decent sound.

To me it just seems unnecessarily complex and violates the KISS prime directive. I'd bet you could get better sound any way by equalizing the active subs and simply using the MC275 for the rest of frequencies.
