If you buy another CA-101 , you can flip it to mono and have 2 mono blocks at 300 watts per.

I would agree with Darrylhifi if you were to change amps though I would suggest vertical bi-amping instead of running them as monoblocks. But I don't think a more powerful amp is going to make a huge difference. Sounds like what you need is more gain so a pre-amp would be the place to get that. There is usually a 10 to 20 dB gain in most pre-amps. That will give you volume.
