Your 50% right : my source and amping are quite good but I had to used the stock cable as it is what the customer has.Link to review?
"not that bad" seems like You didn`t feed them with proper source gear and amping? And did You use stock hideous-high-impedance cable?
I'm very worried by stock cables, bad on most cans including the UTOPIA. sAME FOR THE hd650 with a $18 stock cable.
I would like head manufacturers to sell a combo headphone + cable of the same level.
Thanx for your interesting answer.
