    Hi Guys,

    Im currently considering either of these amps but there is a large likelihood that my centre channel speaker will only be 6ohm and the rears are likely to be 4ohm only. Will this prove a problem to either the Denon AVR3803 or Pioneer VSX D2011?

    Cheers

    Steve

    I would suggest 6 ohms is borderline for the 2011 and 4 Ohm is a definite no-no. It is not designed for speakers below 6 Ohm nominal impedence.

    The 3803 should be fine. You might want to have a look at the Sony 333ES and 555ES which have a switch on the back for 4 or 8 Ohm speakers.

    Check out the Nad Range. The Nad T762 is well specified and goes down to 4 ohms load on each channel without overheating or giving any trouble to the Power Amps.

    Daneel - are you sure that the AVR3803 can manage 4ohms? I just took a look at the spec sheet on the Denon home page and can only find power references at 6ohms?

    How can I find out for sure if either of these amps will handle 4 or 6 ohms?

    Cheers

    Try it for yourself, ask your dealer or email Denon.

    I have been given the impression in previous threads asking pretty much the same thing that you have that the 3803 will handle 4 Ohm speakers but no, I am not sure.

    My 2011 happily drives Kef 60s (4ohms) as rears and Tannoy R1s (8ohms) or Castle Harlechs (8ohms) at the front.

    The power amps will be on a workout as more power is required to Drive a set of speakers. This could result in early faults within the unit itself due to overheating etc.

    No problems at all with my Pioneer 2011 driving 6 ohm Monitor Audio silvers.

    Big confusion as to which will drive lower impedance speakers better. The Pioneer has a more sensitive protection circuit than the 3802 model, but probably has greater actual power (it's a bit of a darkhorse in power terms). Both are supposed to be pretty good at driving low impedance loads, as far as one box systems go.
