Any members have experience with the 1055/1056 receiver driving four ohm loads? I am considering buying a 1056 to drive a five channel home theater with Martin Logan Aerius and Cinema up front and Axiom QS 4s for the rear. My room is smallish (17 x 13) and I do not listen a very loud levels. Is this receiver up to driving four ohm speakers? I note that the manual does not recommend four ohm speakers with this receiver.
1056 and 4 Ohm loads

While the Rotel's should be able to power the 4 ohm loads those Martin Logan's deserve more power then the receiver to really make them shine.- Bottom

Hey guys!
Actually really good question here...I was or am lookin' into buying some Angstrom speakers that were 4 ohm... :cry: I realized....problemo with the 1056....I know I could go buy a really sweet 2 channel 4 ohm amp driven by the Pre amp of 1056....but still what are the problems that could happen driving a 4 ohm speaker on a 1056.....You are doubling your wattage are you not. Therefore you are doubling your amperage....Could be a Problemo...Yes or No ?
Merci. :Got a nice rack to show me ?- Bottom

Bam! that's technically true so long as the power supply can keep up with the current demands and handle the extra heat generated...typically what happens is that the powersupply can't double its output so you usually don't get double the power into 4 ohms even though there's less resistance shown to the amp...even the mega buck amps that on paper show a true doubleing are sometimes just deflating the actual 8 ohm rating to make it appear as if it can double up. Anyway to the Rotel's at hand...they won't shut down with a 4 ohm load but they will run much hotter and will need all the cooling space you can give them. My point above though was that Martin Logan's shouldn't powered with any receiver as they deserve cleaner more robust power then most receivers are capable of generating- Bottom

Well, in the past I have driven these speakers with a Denon 4800 and B&K 307 with no problems and lots of power. However, the feature set on these receivers does not compare with the 1056. The local dealer claims he has cutomers with these speakers and the 1056 and they work fine together, but I am skeptical.- Bottom

Reality occasionally raises its head from time to time. :roll: I am well aware of the effect of good amps on speakers, but my current financial situation will not allow a separate amp now. I need to know if this receiver can drive four ohm loads or not and if it can do it well. As I mentioned earlier, my previous Denon had plenty of power for these speakers but the sound quality left something to be desired.- Bottom

Well I'm sure they do work "fine" together. But do you want them to work "fine" or do you want them to sing? You, your ears and your wallet have to figure that one out
Get your dealer to do a demo (preferably with your model ML's) and if not at least with some similarly difficult to drive speakers with the 1056 alone, with say a 1080, a 1068/1075 ... etc..
