Help with Acoustat Model 1 + 1


I recently bought a pair of Acoustat Model 1 + 1 with Hafler Mk121 transformers. I foolishly bought 'em without testing, and of course, the transformers were near-DOA, but I was able to get 'em repaired and the speakers working. However, I'm struggling with the following and would very much appreciate your counsel:
1. Am I best served leaving the transformers plugged in? Do they need to stay charged? They seem like an electrical fire waiting to happen.
2. I've been testing the speakers with a 150w/ch 80s HK integrated; high voltage/high current, but still need to crank the amp up to get decent volume level. Is it possible I'm underpowering even at 150w?
3. The Acoustat passive sounds marginal; will I encounter any special difficulty trying to integrate a modern powered sub?
Thanks in advance for your insights.

I had MY Accoustats catch fire. I was luckily in the room when this happened, and quickly unplugged them, and returned the transformers to Accoustat for repair. I then sold them. I believe I was driving them with an amp called Ampzilla which was 200 watts a side. I don't remember the sound per se, but I remembered being pleased with them....no bass problems that I can recall
