I've decided to stop messing around searching for a dedicated headphone amp for my current headphones. That amazing sound I've been looking for all along has been right in front of me or better yet right next to me on the left and right sides of my bedroom. The Kenwood VR 7070 drives my Sennheiser HD 515s so well and with a richness of soundstage and low end that in my mind can't be bettered by much. The Sennheiser HD 515s are only 50 ohms. The Pioneer VSX-1016TXV-K coupled with a Soundblaster X-FI Titanium Fatality edition sounds incredible as well with the HD 515s. My room resembles the Bat Cave as I have 6 PCs in there including a 24" monitor, 30" Monitor, a 42" 1080p 120 hertz HDTV, and a 6' * 8' screen with a Sanyo PLV Z5. I also have a fully functional 7.1 surround setup with two low wattage power efficient 10" Yamaha powered subs, Onkyo 606 model receiver, and 6 matching Sony SS 550 speakers. (6 are 8" 3 way speakers and I also have the matching center speaker) I can't listen to my full size setup late at night at reference levels so I am exploring the headphone option.
I've done head to head comparisons with a variety of low cost options from Behringer including the HA400 headphone amp, the MA400, and AMP800. In my humble opinion I have found that the ultra low cost HA400 and MA400 are only very good options for unamped sound cards such as the X-Fi Xtreme Audio, Audigy SE, Xonar DS, and X-Fi Surround USB. For my purposes I have found that the only thing I really enjoyed with those amps is my 32 ohm Creative Labs MK II. That set of headphones seems to get no love. They even sound great with my moms Insignia Ipod. They may not have the best soundstage but they cover a wide frequency range and are so comfortable. They do get your ears hot after hours of use. When amping the Sennheiser HD 515s the sound is much thinner than using either of the headphone outputs on the Pioneer or Kenwood receiver. Keep in mind that both receivers cost about $500 when I bought them. So they better damn well sound a lot better than $30 headphone amps.
Realizing that ultra low cost amps were not going to offer what I was looking for I decided to make a slight step up in the Behringer AMP800. That offers about 2 times the power output of the MA400 that is rated at 60mw into 100ohms. The AMP800 is rated at 124mw into 100ohms. Well in testing the Behringer AMP800 on 2 separate PCs I've come to the conclusion that it is not a good amp for the Sennheiser HD 515s. In short the output is too hot/bright and does not sound as balanced as either of the receivers output. As a test I put on Michael Jackson's Thriller and Wanna Be Starting Something with the AMP800. I most recently tested with the X-Fi Titanium Fatality as a comparison to my other setup with a Xonar DS. It sounds almost exactly the same as the Xonar so I concluded that it is the AMP800 that is messing with the mids and highs causing fatigue after some time of listening. I'm not really sure whether this is a case of over amping or under amping but the bottom line is that it doesn't quite sound right. I don't think it is right to call the Behringer AMP800 a POS but it just does not suit my needs for audio heaven. I'll probably see if I can salvage great sound with my Creative MK IIs. They are geared more to the bottom end so an amp that favors mids and highs might offer a good experience. I'm not even going to attempt to try my Sennheiser HD 202s. I don't want to be as deaf as a World War II vet.
Listen to the music!!!!!
