So I am re-designing my system slightly and trying to decide which amp to use to run my front stage as I have 3 different amps sitting around. My speakers are ADS 335is's and between the head and the amp I will be running an EQX. My choice of amps are:

1. ADS PQ20.2
2. PPI 4480
3. USAcoustics 4080

All 3 amps are rated for the same 4x80 power and pretty much the same bridged power. I will probably run the amp in bridged mode but I could run 4 channel mode to have more control over the 335is seperates. The PPI and USAcoustics have built in 12db/octave x/overs and the ADS doesn't. I have been running the ADS PQ20.2 to run the front end but have had people suggest using the PPI or USAcoutics instead as it's a better amp all around gives me more flexibility.

What are your thoughts.

 

I would personally go with the zed audion USAcoustics.

 

I had a US2150 great amp not complaints!
