Hi guys, not sure if this is the most appropriate forum, but here goes... I have a new Pioneer VSX-1018 hooked up to a Jamo a102 5.1 speakers/sub package. I've run through the MCACC setup a couple of times, playing around with the settings, etc. From what I've read on here, Pioneer's MCACC is considered quite a good auto-calibration? My question is a very newbie one, on the speaker channel levels. MCACC has set all mine to in or around -5.5db or -6db. I'm wondering, why the negative (below zero) values? If I manually increase them, the amp's volume obviously increases. Why does MCACC seem to prefer to set them to quieter levels? I sometimes find that I have to crank up the volume a lot more than I would have expected to, depending on the source I'm watching, e.g. -30db to -25db for Sky+, and at least -25db to -15db for blu-rays or DVD's. I would have thought that using an Amp with this spec, I'd have had to turn it down a lot, but I tend to find the opposite! I suppose, being a newbie, I'm hoping I have it all set up optimally! Joe.
