I'm afraid my A/V receiver may be on the way out. It's suddenly taking a lot longer for it to output audio. I don't think it's anything else in the chain since 1) it happens on both my PC and PS3, and 2) my mains are powered by the ADA-1500, so if it was that or the LFR1100 DSP, the surround speakers would start playing before the mains. I may have to get a new unit sooner than planned. Grr.
