CJ 2300A VS 2500A W/ALON IV'S......

I recently had to change out amps to put my 2500a in the shop for repairs (assoc equipment)

1st system:
cj 2300a, cj pv10, nad 565bee,and alon II's

2nd system
cj 2500a, cj pv12, rotel 975, and alon IV's

I had to have the 2500a serviced so I changed things around a bit. I found the alon IV's sound better with the 2300a and pv12 combo. I didn't think the 2300a would be able to handle those IV'S without those bipolar outputs but I was wrong. as a matter of fact, they sound cleaner and clearer.
