so Andreas is not god's word after all
after listening to the 49720NA very carefully, I don't really see what the fuss is all about.
if you can justify the US $75 a pop to go burson, they simply seem to be a no-brainer...otherwise for a couple of bucks the 49720NA will hit the spot. I read on a french forum that if the 5532 is 0%, then the 4562 is 70% and the burson 100%.
like these ppl having zillion pairs of headphones, why not just a very good one instead? like a HD800 or a R10? why collecting/paying for zillion op-amps when you can get a bunch of burson, and simply move on..
I'm highly doubtful that the LT1358/LT1364/LT1028ACN8 will make me forget about that magical sound the LME49720NA manages to output...but never say never I guess
