    a. Power Amp - rotel RMB-1075

    b. Processor - rotel rsp 1066/1068 or better

    c. New Surround Receiver - yahama 2400 /2500

    d. Integrated Stereo Amp.- arcam or roksan


    The main issue is to improve the overall sound quality both multi channel and stereo. I like the sound of my old yahama in 5.1 but the pioneer is very good in stereo but not so lively in 5.1 or 7.1. I take it that improving the dsp processing will improve the overall sound much more than improving the amplication.

    £800-£1000 to spend.

    What speakers do you have ? I have a 2011 that I nearly got rid of but a quick demo turned up the source of the whooly sound was the CD player. Turns out my "it's an AV amp - it don't do stereo" 2011 works brilliantly with stuff all the way up to a Cyrus CD8x and you still keep hearing the diffence in source quality (though perhaps not as much as if it were wired to a Cyrus 8 amp or similar with 2K speakers but hey - I've only got so much to spend on hifi).

    One thing I did find with the 2011 is it doesn't like the 4ohm setting. I had a mix of new and old kefs - Q7 and Q35s (the latter 6ohm). When I replaced these with Qcompacts - no difference. Then I remembered the ohm setting on the amp and bingo - whole new dimension of sound appeared. I guess the amp isn't hugely powerful (the newer KEFs are all sensistive easy to drive speakers).

    Only thing I would say after a demo I had last week - go listen to some kit - it really does clarify the source of the issue and then you can get the right piece of kit.

    Acoustic Energy 109 (biwired A+B speakers 2011s) floor standers.

    Mind you they are a few years old, but were oustanding speakers in their time. Will check the ohm settings though!

    Centre Mission 75c 6 ohm, Front AE 109 6 ohm and Rear Mission 750 LE 6 ohm and my 2011s was set at 6 ohm! Speaker cables: QED Silver Anniversary: Biamped on Front AE109 and Biwire on Mission Centre 75C.

    Hmmn. :confused:

    Might be the source of the problem - the Pio I guess doesn't have enough juice to do 6ohm stuff well perhaps - so it probably is the amplification rather than processing that's the problem. You need a mate with a power amp to lend you to see if it makes all the difference - just taking the load of front left/right speakers might make a big difference. I didn't try this route myself as the other half wanted rid of the floor standing rears. I'd definately want to do a home demo of a £1K piece of kit first though just to confirm if it solves the problem.

    I'd looked originally to sell the 2011 (one sold on ebay for £500) and upgrade to arcam avr300 but I wasn't impressed with it at all (in fact prefered the 2011 in stereo !!!! now if that doesn't buck the trend to the arcam - both runnning direct source, no processing etc).

    Best of luck

    The Pio should be fine for 6ohm speakers.

    Pioneer 2011s is rated at 100w into 8ohms!

    How much do get from 6 ohms speaker settings? :confused:

    Power amp, but perhaps something a little higher up than the Rotel 1075. You might consider a second-hand 2 or 3 channel amp and leave the rest with the Pioneer.
