I've an older Onkyo 905 and lately I've been toying with upgrading. I've looked at the latest Onkyo offerings and might go with a NOS 5090 or the current 3010. But for about a grand more I could go with a separate pre-amp and power amp outfit. Anyone else go this route? Is it worth it? Would I gain anything except more cables cluttering up my AV furniture?


Also what's the deal with balanced XLR inputs and outs.


Worf...
