Of course, you'd need to have all the "stuff" (sans speakers) disconnected this way too for the test.
I don't remember the buzz before installing the outboard amps. Could be that it's the amps (doubt it though,.. B&K is WAY higher quality stuff than Pioneer,... and there's no buzzing sound when I play my Adcom CD player through them.)
Another possiblility is the in-board amps have less gain than the B&K amps do (when the B&K gains are cranked all the way up),..... so I just don't notice the buzzing with the internal amps, just as you don't now with the B&K amp's gains at 1/2 volume.
Who knows. But as long as the Pioneer's pre-outs can put out enough level to fully drive the amps with the gains where they are,.... it's all good.
I am also working on cleaning up some cables. At the moment I have a Samsung Blu-Ray player AND also a region-free Bubugao DVD player. The DVD uses massive Monster Cable component video cables AND a coaxial digital for the audio (4 cables, each 6' long) and the Blu-Ray uses a 6' HDMI cable. (sp a total of five, 6' long cables).
Today I ordered an OPPO 93 Blu-Ray player that's been modded to play all region DVD's. So I'll replace 2 units and 5 long cables with one unit and one 3' HDMI.
I also ordered 3 each of 3' and 4' HDMI cables so I can shorten some lengths.
I'll keep working on it,.. but I'm pretty sure the Pioneer is just noisy. Pioneer lists their IHF signal-noise as 103db,.. and the Marantz claims 105 db. Of course I learned years ago to not believe anything a Japaneese manufacturer says about their electronics (or motorcycles). 45 watts x 4 in a car head-unit. Yeah right! With 200% distortion, using a 4,000 hz test tone and measuring the current at the inputs of the output devices,.... MAYBE. Actual RMS output 20 hz-20,000k is likely to be 18 watts or less.
Sure would be nice if McIntosh produced an AVR that did everything the Marantz AV7005 does,.. and then sold them new for $1,500. LOL
