New Head-Fier
The HD6xx IMO is one of the best bang for the buck bargains in this hobby,assuming you enjoy a warmish sound signature. The next step up would be the LCD-2 pf and then the ZMF Aeolus for similar sound signature.
LCD-2pf when new was $1000.00.
ZMF Aeolus-$1200.00
Thanks...I'm going to head over to the guy's place today for a listen.
