Go for it. I have had several pairs of ML speakers over the years. I was powering them with a pair of Krell monos and I didn’t know what I was missing until I borrowed a Cary Audio 120 amp which simply destroyed the Krells. One of my buddies was there when I first hooked up the amp and he couldn’t believe the difference. He ended up purchasing the amp which he still has and I went with a pair of the Cary monos. Neither the 120 or the monos ever ran out of steam no matter what type of music I played. The panels would always reach a point where you could turn up the volume but they wouldn’t get any louder well before the amps reached their limits.
ML states that the Neoliths are 90 db efficient at 4 ohms so you should have more than enough headroom unless you are playing them in a huge room. Also, does the woofer section have its own amplifier like other ML speakers? If so you are only powering the panels. If they aren’t self powered I still think you will have more than enough juice with the Bats. If Neos don’t have built in amplification for the woofer section you could try using your Krells for the bass where they do excel and the Bats for the panels and get the best of solid state and tubes.
Good luck with your system which I would love to hear.
