I am considering going with all HK stuff or all Sony ES stuff for my HT. I've been an avid Denon/Onkyo user for a few years, but it seems that their latest stuff just isn't all that its cracked up to be unless you buy their top $1k+ machines. I'm not really crazy about seven channel stuff as I don't think my room size would benefit from it nor do I like the idea of buying more speakers. So, I don't have much of a problem with buying an older Sony ES unit like an STR-DA50ES or a STR-DA333ES. I've been looking at a few HK receivers as well such as the 110, 120, 210, 220, 310, 320, 510, etc. (they don't seem to be much different from the new 'xx5 series other than price and I don't mind buying used). SO, I would like to know if anyone out there has experience with both the ES and HK receivers and why you chose one over the other. No one around me carries both ES and HK in the same store so I have not been able to make an educated AB listening comparison yet so I would like some experienced thoughts from some of you gurus out there. Thanks!
