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'm surprised I'm not getting any reply. Maybe I asked a stupid question? If so, would appreciate learning how it was so. Wouldn't be the first time, though :-)
Lewinskih01- I think what has me baffled is why you would want to use an SET on the tweeters in a 3 way. The vast majority of the musical information is conveyed by the midrange and that is where SETs really deliver their magic. Also, I believe that one of the knocks on SETs (I don't know if it's true) is that they are bandwidth limited, which again would argue against using them at either extreme in a 3 way.
Fair enough.
Maybe I was jumping to conclusions.

My 4-way would be divided as follows:
20 to 80 Hz by active subs
80 to 600 Hz by two 10" midbass woofers per side, driven by class-D amp.
600 to 2500 Hz by a midrange. Was assuming my MC275 for this. Most midranges are somewhere in the 94 to 100dB sensitivity and 4 ohms.
2.5 to 23kHz by the TPL-150H at 102dB sensitivity.

Do you think I'm better off using SET in the midrange and having the MC275 do the higher frequencies?
