Hello. My name is Rob, from Australia.
I recently upped my home stereo to a pair of RT1000i powered towers, and set them up on my dedicated Yamaha 2 channel amp (for music only at this stage, not HT).
I've had them one week and they're single wired on monster cable, the amp is soon to be upgraded, but when going to sleep, i noticed an electronic humming from the speakers, one in particular. It seems to come from the power amp at the back, even when unactivated (they turn on when they sense amp signal), and signal cable removed. When I switch them off at the wall they stop humming, ofcourse. Down the back, and from the bass port is where the noise comes from. Is this normal? Has anyone else experienced this? And should I turn them off at the wall all the time when not in use? It is reasonably quiet, but has me worried!
My second question is recommendation of amp power per channel. I'm interested to consider NAD at the moment, or marantz? I'd rather the no bells - and - whistles option and go 2 way. Does anyone have a similar setup and recommend a particular model? The speakers are rated at 250w peak, suggesting i'd probably want about 120 / 140watt per channel amp I guess. I have a particularly dynamic sound taste, in that i like the highs and lows, and I want something with grunt that'll out-pace the towers before running out of steam. I'd rather a single amp, with no pre amp as finances are restrictive, and bi wiring option would be nice.
Lastly, much of my music collection is now stored on computer for daily use, as I prefer the navigation. Is anyone else using such a setup, running computer into amp? Is there a way to restrict the sound to the standard input signal without upgrading to an external USB input? I am concerned to damage amp and speakers. Is this concern valid? And have any reputable brands developed such USB devices inbuilt to amps? As yet I have held out, using only the CD player. It's difficult!
Thankyou for your help.:)
