SET on JBL Everests - Mouse breeding an elephant?

I have a set of DD67000s and I’ve been running them on a pair of bridged Mac 275 amps.  I’ve been quite happy with the results even though most advise a lot more juice.  Lately, I’ve been hearing interesting things about the Elekit TU 8600s and I’m curious how that would work on the Everests.  Most of my listening is to acoustic guitar, jazz ensembles, piano (classical and bill evans jazz), and intimate vocals at fairly low volume with the remainder being orchestral/symphonic, early rock, big band, Texas swing at higher volumes.  Room is 22 X 40 with vaulted ceiling.  I’m thinking of adding the SET for the smaller scale stuff and leaving the 275s as they are for the rest.  Thoughts?

A couple 9V batteries in crossover? I just read the D67000 manual and it says the internal crossover has a couple 9V batteries to keep the crossover energized. Has anyone heard of this approach before and does any other speaker manufacturer do this?

The 9 volt batteries keep a constant charge on capacitors in the crossover. Similar to a class A amp were the transistors are always on.

Vandersteen have been doing this for two decades. The amps use 128 v on the IC and speaker cables. Keeping a cap fully formed is important to sonics, including in delicate small signal electronics. There the approach is proprietary..

Thanks for the info, much appreciated. I just recently started upgrading and had never heard of this approach.
