Tobes, I finally found out last night how good the Sennheiser HD 600 cans really are. I received yesterday a Benchmark DAC 1 Pre. I'm floored by it. After listening through my system all evening, I decided to plug my 'phones in, I was just amazed how good they sounded
I'd been using Musical Fidelity X-Cans for around twenty years. This will probably induce me to do a bit more headphone listening, though I prefer listening my speakers more.
I've read a lot of good things about Benchmark's AHB2, one may have to go on my long-term wish list.
Regards, and enjoy,
Dan
