If you are going to upgrade amps, at least get double the power. If it is already more power than the speakers can physically handle, its useless.

Thank you for the frank reply. Thatís exactly the type of information I find useful. To clarify, I'm not wanting "louder", simply better SQ. seeing how I will have to buy something to drive them; I want better than I have now, not the same or worse. Make sense? For example, the stereo in my truck. My subs are rated at 500 wpc 4ohm ea. the first amp I had was 1000 watts. I replaced it with a 1500 wpc amp and they sounded completely different. Tighter, fuller and just plain better. Not any louder, just better.

Well I woke up around 4 am this morning with an epiphany. If the 272 doesnít do it for me power wise, Iíll buy another one and run the two in bridged mono. That would give me 300 wpc with 1132 wpc IHF dynamic power. Donít think Iíll need to do that, or even want to, but itís an option that would only be a couple hundred than the Rotel 1080.

So I went ahead and placed an order for the 162 / 272 combo a little while ago. Hopefully, theyíll be here before the weekend so I can set them up and play with them and have a couple days to do some comparative listening between the HK and the NADís. What really tipped the scale toward the NAD over Rotel was the pre-amp. I like the tone controls better and I also like the variable pre out 2 that the NAD has.

And seeing how Iíll need somewhere to put the new toys, I ordered a cool EQ rack to set this stuff on that will go very well with all the stainless I have in this area. I bought it from AV123. If youíre curious, itís the silver one with glass shelves. The friggin shipping costs on the rack was as much as the rack, so they gave me a pretty good deal on the rack to help ease the pain.

After I get this stuff set up, Iíll let yíall know if I can hear a difference.

You will not be able to run the NAD amps bridged pushing a 4 ohm load.When bridging any amp the load the amp sees is cut in half.So if you were to try it with the 80s then the amp will see a 2 ohm load.

Well crap....

I can still use two amps and bi-wire them, can't I? One amp to the LF and one to the HF?

Yes Mike you can but you will still be pushing the 150 watts to each speaker.A waste IMO.

excuse my ignorance (and if it isn't obvious by now, I'm completely audio ignorant). but.... wouldn't I have 150 wpc going to the LF drivers and another 150 wpc going to the HF drivers? for a total of 300 watts into each speaker...what am I not understanding here?

You would have 150 going to the lower side and 150 going to high side.You would have that just leaving the straps on the binding post in place and just run the one amp.

I feel like a dumbass now. Can't believe I didn't think of that. the olí parallel/series wiring rule.....there'd still be twice as much available current though. Or am I wrong there as well?
