My current system consist of HK AVR-525, RTi150s (front), CSi40 (center), and RTi38s (surround). Although (to me) I seem to be satisfied with the way the RTi150s sound in 2 channel mode (HK AVR-525 puts out 90 watts per channel in 2-channel mode), I have this itch to buy a 2-channel amp to drive the RTi150s - for now using the pre-outs (front channels) of the HK-525.
I am thinking of getting a NAD C272 (150 watts x 2) power amp. My questions to all the polkies out there are:
1) Will the NAD C272 do a better job than the HK-525?
2) Is this worth doing?
BTW, I recently had a chance to try out a pair of the NuForce Ref 8b (mono amp which puts out 100 watts per channel). After a week of doing A/B comparison between the HK-525 vs NuForce Ref 8b driving the RTi150s (in 2-channel mode without subwoofer), neither I or my wife could tell the difference. I could not believe that the HK-525 sound so good in 2-channel mode.
One thing I need to mention is that I recently had a dedicated 20-amp circuit put in for my HT room and I think that this is what makes the HK-525 sound so good (as compare to previously when I had all my components connect to the old 15-amp circuit).
Thank you very much for reading my post!
