With a crossover of 225hz, you need MORE power ABOVE then BELOW if you intend to run out of gas about the SAME time.
Also, unless you are using a LINE LEVEL crossover, you are NOT gaining any power. BOTH amps are STILL required to reproduce a full bandwidth signal.
A line level crossover, either of the Passive or Active type will net you as much as 3db additional power.
Your example with nearly 8db of output difference between the 2 amps AND the crossover near the theoretical 50:50 point of 350hz, means the tube amp SHOULD run to cllipping first. Way First.
I LIKE the idea of disconnecting AC before doing cable swaps. Real workmanlike.
You MIGHT have, as someone suggested, simply run the fuse near death. A 25 watt amp trying to keep up with that Parasound is a losing proposition and I'm sure you ran the tube amp near redline much longer than you suspect. With nearly ZERO headroom.
Too much is never enough
