Re: Eclipse XA4000 or XA5000
The channel separation is fine on the P900.4, meaning it's within inaudible limits. I ran a P900.4 for a year with an RTA tuned 3-way active system and the only reason I got rid of the amp was to get twice as many channels in the same underseat location. It's hard to say for sure, but I believe the P900.4 has a slightly quieter noise floor than the Massive BX4s I'm running now. Either way, they both sound great.
