Onkyo PR SC886 can't drive my prosound amps

Hi All,

I bought the Onkyo PR SC886 used and have it connected via XLR to Ashly FTX 2001\2000 and 1501 amps for surround sound plus a Crest 1500 for subwoofer. With the volume control reading -10 or louder the amps are barely pushing peakes at 20 watts. The preamp sounds poor with the volume control reading louder than -10. Is there an adjustment to get more gain on this pre\pro? It sounds great in the -20 range but as it gets pushed quality goes downhill fastand it isn't that loud.

Any sugestions would be great?

Thanks,

Scott

This pre realy shows off the quality differences in formats. Direct DSD is hands down the best sounding format\setting on this pre. I'm using a cheap $99.00 Sony blue ray player via HDMI for source. I'm certainly not going to run out and my a big $$ player.

I looked up the manuals on the Onkyo and Ashly 2001 amp and at a quick view couldn't find any settings to make when using the XLR connectors, and the amp only has XLR. So I'm almost thinking you have a bridging switch set incorrect? Or perhaps there is something in the Onkyo settigns that I (or you) didn't see regarding using those outputs.
Can you borrow a "regular" (non-XLR only) power amp from somebody with RCA cables and see if that works for you? Just to test where the issue is coming from. If the non-XLR amp works then you've narrowed it down to that set of outputs at least.

  yes, I'll try that. I was hoping there was some dumb setting I missed and a member could direct me to. The mutes are fine.
  
  I think the Ashlys sound a little better driven fully diff then with a non-ballanced converter.
  
  My cheapo adcom tuner/pre can drive the amps to peak red at half volume.
  
  I like the sound of the Onkyo but it sounds best below the -10db mark.
  
  Thanks,
