I wonder how a pair of AD797's or the AD8397 would sound? I have often found the 4562 to be a little HiFi sounding but it is also in the implementation so I am glad it sounds good in this setup. In looking at the board it sure appears you are getting very much for your money. This is more like a low wholesale price. I have seen amps in China selling for 40 dollars and have no idea, even with their low wages and living cost, how they do it. My friends in China just say, "this is China, we can make thing cheap". I bought a soldering iron there that I still favor using over everything else I have. The cost, $2.25 and tips were 25 cents and the first one is still going strong (much better than my Weller tips that cost 6 dollars or more.
Has anyone compared this to headamps costing much more?
I keep finding myself listening too it and enjoying it, when I could have listened to something else. Have a good one!!
