It took two months of burning in and finding the right aftermarket cables to make these my desert island cans! My system is made of an old Rotel cd player(9 + years) for digital out put and my pc with JRiver Media Center for flac files of my cd and vinyl recordings and high res audio files. I have had my Melos SHA-1 tubed headphone amp/preamp for almost 20 years! Transparent Audio Super cables for interconnects and Ultimates for speaker cables. From my PC to Pangea USB to my M-Audio Fast Track to Tara Labs RSC digital into my Bryston BDA-1 to said Melos SHA-1 headphone amp. I have HD600s, 650s as well as the 800s for ear pleasure. Recommended Moon Audio cables are use with all my 'phones. Audio Prism mkII power conditioner and Tara Labs, PS Audio and Cardas cables for power cords. I use Mapleshade Isoblock equipment stands. Speakers by Eggleston Isadoras and power amplification by Balanced Audio Technology's VK100. I've been a sound head for 30 years. I always have played with cables to get my sound as full and accurate as possible.
 
The music I listen to goes from David Sylvian, Brian Eno to Coltrane and Shostakovitch...
 
After my DH800s broke in with their stock cables I figured it was time to see if I could get them to sound fuller and less over bright. I shopped around until I found Drew Baird's website moon-audio.com, man was I impressed. Not only are his cables made of impressive materials but the terminations and construction quality are the absolute first class. I think I could use these cables for many, many years to come! With his Black Dragon cables sourced for the HD800s I was able to get very rich, warm and accurate sound from these cans! The highs were put into place with liquid highs and warm linear mids to full bodied bass(maybe not the end all bass but...). Image separation is amazing and the depth presented is unbelievable!
 
So it's happy ending for me. Don't wanna know 'bout the latest plannar Magnetic cans out there. I'm done,,,,, for now!
