I'm so happy. Got the setup working,as described, using the multi channel phono line out from my Onkyo hdmi-capable receiver to the far superior amp section on the Sunfire UR-II via its 8ch analog input section. The 8ch. Input is used, and I have tuned the sound output levels so that the old receiver powering the side channels only is in line with the sunfire driving the rest of the speakers- via my trusty radio shack sound level db meter. I have even tuned the setup so that signal level out to the sunfire is offset -10to -12db, set in the hdmi receiver, so as to gain the maximum possible output level wise headroom overall. When the Onkyo only drives the side channels, it might be able to follow the Sunfire driving the other speakers via 6 amp sections. (6.1Setup, biamping the main L + R stereo speakers using 4 amp channels). The channels run from the onkyo receiver is sent as phono signal at a relative lower level, and the sunfire boosts the real output via its own volume. Thus I gain more headroom by using the superior amp power from Sunfire to the maximum potential...EEspecially driving a direct stereo signal I hope to gain max level and quality. (And the onkyo I hope can follow in SS, driving only two medium B&W 600-series speakers..) (The more the signal can be amplified, starting low at phono line level, the more space to the top level - output wise, via 2x200w. pr side for the main speakers. And I think the sunfire far surpasses my onkyo, no matter the more than10db signal level difference This way I hope to get a maximum sound pressure level in stereo .. that's probably as high as I dare drive the old trusty B&Ws. Thanks for the help guys. Johannes

I Plan on using bananas for speaker wire termination, since there seem to be only small holes for bare wire?!

Ideas and info regarding splitting signal to front speakers?Will a Y splitter be best, but with a lower signal level, or does the UR2 line out follow the input so I can input from there to another two amp sections directly via the 8ch input.. From where the front l/r input is then used as line out source on the fly. What about levels and speed of signal etc? Level settings volume wise?, And perhaps sound mode when planning to (?)/use the 8ch analogue input sets Thx in advance Johannes

Link in question regarding trouble with UR2 as power amp: http://www.avsforum.com/forum/90-receivers-amps-processors/1953769-sunfire-ultimate-receiver-ii-power-amp.html#/forumsite/3207/topics/1953769?page=1 It's not me, but basically same question..RegardsJohannes / offcourse_dk26

Thx for reply. I'm asking since another guy had problems with connecting the sunfire UR2 to another receiver via the 8ch inputs. So specifically I wish to send front speaker signal out to use 4 amps to biamp the B&W, and then use two channels more for rears, and the last channel for the center speaker. My last rear center in the 6.1 setup can run from the Onkyo. My Sub is the Sunfire signature 12" eq. Rest is b&w- either 800 series matrix our newer 600 series rear side and center. Hoping to get even more oomph and iron control, slam and power. Regards Johannes

Im looking into using the UR-II as power upgrade via the 8 CH input. I wish to Biamp my speakers (b&w matrix 803 s2)with 2 x 200w. Pr. Side/ speaker. My plan is using a more modern HDMI receiver as controller, and the Sunfire urII as power AMP. Would this Work? (Sure hope so Thougts: Wish pure signal, but pure direct mode is 2ch. Only? 8ch. Input is also sort of pure, described as a "short analog Path".. Will auto on Work, and should I use a preset of Max volume, or what? ( audio out signal from other receiver is not fixed, but follow that first HDMI-receivers general volume level) (Its a weakish onkyo tx-sr 805) I Think I should split the phono audio output from the onkyo ( rca/ phono ) to double to input cables to the needed 4 desired power channels - instead of the 2 outputs L/R.? Will this halve signal strength? Can I just turn the Sunfire up?or let onkyo auto correct via mic test and then bypass dsp via direct mode afterwards for pure Sunfire bliss? Thanks in advance Hoping for advice / correction/ confirmation of the above. Offcourse_dk26. /. Johannes - Denmark

Im looking into this as Well, using the 8 CH input to Biamp speakers is my plan, using more modern HDMI receiver as controller and the Sunfire urII as power AMP. Would this Work? Sure hope so
