Using a Rotel RSX-1055 as a pre/pro? Best way to incorporate external amplification?

    Right now I have my RSX-1055 running Dynaudio Audience 122 mains (6 ohm) and Dynaudio Audience 42 surrounds (4 ohm), with a Dynaudio Audience 122C (6 ohm) to arrive this week. This is quite a load for a one-box solution like the 1055. I'm thinking about picking up a multichannel amp to decrease the load and I'm torn between two options. 1) A more powerful three channel amp for the center and mains with the 1055 running the surrounds and a set of rears that I plan to add in the future - another set of 4 ohm Audience 42s. 2) A more powerful seven channel amp at roughly 100-120 Watts per channel at 8 ohms with the 6/7 rear channels being added in the future.
    Which option would be a better route? Would the savings on a three channel amp (over a seven channel) be worth it, even though I would still be running four 4 ohm speakers on the 1055?

    Advice is needed.

    Ryan,

    Someone on this forum is selling a pair of Marantz MA500 125 watt monoblocks for ~ 300. Get these, add a 3rd monoblock (see audigon & ebay) and you would have three nice amp channels for your mains and center for ~ 450. The Rotel should be fine with those four rear speakers.

    Going with a series of MA500 Monoblocks, if I can find quality used units, would be an affordable way to get the power range and headroom that the Dyns demand. Thanks for the tip.

    If it was me...

    How about a Rotel 1095?... 200W x 5... will let your low-impedance speakers sing (and keep any future speaker choices flexible)... can't go wrong with more power... will also facilitate DVD-A / SACD, if you're interested.

    The 1055's configurable amps can drive the rears (ch 6/7)... mostly ambience, easy on the receiver.

    I see used 1095's on Audiogon once in a while.
