So after being delayed by UPS & Sennheiser (but - to their credit - not ALO Audio for their cables and Woo Audio for their incredibly sturdy HPS-R headphone stand), I've finally gotten my entire system, and I am so incredibly thrilled. I've got my Sennheiser HD 800's, the Senn HDVD 800 amp, the ALO Audio Green Line with 4-pin XLR attachment (which is well worth the purchase over Senn HD 800's included 1/4" standard cable when using the HDVD 800... The standard 1/4" cable doesn't compare), AudioQuest NRG-X3 10' power cable (I needed the extra length for my setup, and my HDVD 800 didn't include a power cable... Odd), and AudioQuest USB Digital Audio Forest cable (yes, it's overkill, but - at this point - might as well keep my system and its cables top end)... I'm also using Amarra for digital playback. Anyway, this system is more than I could have ever asked for.
This combination is incredibly fast, detailed, transparent, and - for me - incredibly absorbing. I understand and appreciate the desire for that warm tube sound... However, I'm a film and television editor and - when given the choice - I prefer a more "transparent" sound (we can argue all day long whether a tube or solid state sounds more "natural," I know)... I'm using my headphones and amp for both personal and professional reasons. It's a ridiculous cliche - especially posting on a site like this - but I've tested the HD 800's before and never quite experienced my favorite albums like this before now. If you want to hear your music (and other audio) as they were intended by the source, give the HD 800 and HDVD 800 combo a try.
I'm currently listening to my favorite album of all time - Pink Floyd's "The Wall" (yes, "Dark Side" is more consistent, but "The Wall" reaches for such greater heights, in my opinion) - an ALAC from the 2011 Re-Mastered CD - and it's glorious. The last time I was this affected by this album was when I was 4 years old and asked my folks to play "the baby song" (Track 1 "In The Flesh?" of "The Wall"... which ends with a plane crash and a baby crying. I was a strange child.) Listening to this has been so incredible, and mostly, I just wanted to post my reaction to say thank you to the folks who suggested my new system - and who expressed their opinions of others...
The truth is, music (and audio in general) is such a subjective experience... But whether you agree with my preferences or not, I just wanted to say thanks to you all for your valuable experience in evaluating my decision. I love it. It's one thing to be able to experience a pair of headphones in the store or from a friend... But there's so many variables and combinations of equipment, it becomes something of an obsession (and a fun one at that) to find the perfect one... And all of you, your experience, and insight made it possible. Thank you so much,
