Yeah, I decided to go the multiple amp route...having an OTL amp for my high impedance headphones and SS for the rest. If you envision getting some more of these types of cans, then an OTL amp may be a good investment for you. Otherwise, the Lyr may be a better play. My personal thought was I'd rather get the Valhalla 2 and then upgrade my SS amp...was thinking Asgard 2 prior to the Jot being released; probably will go with Jot now
FWIW...don't have much Hip-Hop / Electronic but took the time to listen to several songs from The E.N.D. by The Black Eyed Peas with the HD800's and the HD650's on both the UDA-1 and the Mimby/Vahalla 2.
A few observations:
- Not a fair fight between the Sony vs the Schiit...that said, I paid $200 for a new UDA-1 on Woot vs $950 for the Mimby/Vahalla 2 stack...sometimes, you get what you pay for.
- The Black Eyed Peas on the HD800's / Schiit stack sound pretty darn good to my ears -- enough bass, etc....so do the 650's! On the UDA-1...Meh.
- I wouldn't spend any time with the HD800's on the UDA-1 (and haven't) but it's not what I bought it for.
- TBH, the Sony is a solid, swiss army knife for a computer desktop system including DSD and the ability to drive speakers. Jack of all trades; Master of none.
A question/consideration:
- If the SE846's (known to be bass heavy) are your preferred signature and the HD800's sound 'thin/harsh no bass etc etc', why don't you sell the Senn's and get cans closer to SE846's signature?
Below is an FR graph with the 650's, SE846's, SRH1540's, and HP50's. As an example, the SRH1540's seem to come fairly close to the SE846's and hopefully share some Shure house sound similarities
(innerfidelity review here). Never heard them but they appear to have a sound signature quite different from the Senn's. Another option would be NAD HP50's
(innerfidelity). Just two of many options...
