Dear Experts, Afficianados and Enthusiasts, I am the proud owner of a HD650 for about 3 years now - and enjoy it thoroughly (though I frequently switch to HD595 for a polar opposite immersive experience :) ). I use it mated with an iPod Classic LOD to Headroom Micro-Amp / JDS Labs O2 amps, and only use high quality bit rate inputs/ALAC.
I have been reading tons of material about how well tube amps complete the union with the 650. Have narrowed down to Schiit Valhalla. My question is - am I really going to experience a wow factor difference before i drop down the 400 bucks? All views and as many as possible welcome. Thanks and happy listening! Chris.
I have not heard any better amp for the 650 than the Bottle Crack. If you have no diy skill, I'd find someone who does and ask them to build it for you. That's what I did.
