My new Sennheiser HDVA 600 headphone amplifier and Sennheiser CH 800 S balanced headphone cable arrived today. It didn't take me long to get the Musical Fidelity X-Can V8P headphone amp out and the new HDVA 600 installed. The headphone rig now consists of a Sony Vaio/JRiver Media Center 19 via USB to the W4S DAC2, Oppo BDP-83 as a transport feeding a digital signal to the Wyred 4 Sound DAC2 which is feeding the Sennheiser HDVA 600 with balanced Wireworld Silver Eclipse interconnects, Sennheiser HD800 headphone with CH 800 S balanced headphone cable. I have 13 hours on the HDVA 600 amp and about 28 hours on the HD800. Considering that break-in is on going this setup is sounding outstanding. Listening to Lee Ritenour - Rhythm Sessions hi-res download (24/96) right now. Just fabulous.
Congrats. Thats an envious set up you've got there!
