I find the hd700 unbalanced and not natural. The hd600 is still the sweetspot In the senn line. Very coherent, great mids, Speed AND body. The hd650 needs brutal power , otherwise its not as good as the hd600. The hd800 is bright and can't do the body as easy as the hd600 does. Get an lynx hilo or grace 903 with the hd600 and you will have a fantastic setup.
Sennheiser hd 650 vs hd700
Does anyone have a strongly held view on whether the 700 is worth 2x the 650? I will be using computer source thru a rega dac and rega ear. I know it is not twice as good, but given my tendency to buy things 20 per cent different. My plan b if I don't get the 700 is to get the 650 and wait on a deal for beyerdynamic t1s. Thanks.
