Hello, I currently own a nice balanced setup (Audio-GD Roc + Ref.5), driving some HE-5LE.
The sound is alright, but I feel is too 'cynical' and analytical: good recordings are fine, bad ones are thin and harsh.
Also, for problems unknown the sound is inconsistent, even using same recordings, some day is fine, some other days is only OK. it could be a power problem or maybe my ears simply need some rest :-)
I'm selling my HE-5LE, because they're too heavy for me, I find them uncomfortable. I think I'll go for some HD650 or DT880/600ohm (I'm leaning toward the latter), I used to own them, I like the sound (though they're different) and they're extremely comfortable.
I can't afford (and I don't want) to have two headphone amps, so I'm going to sell my Roc (I think I'll keep the Ref.5 because is very very good), and buy a good tube amp. I never had tubes before, so I'm looking for some good suggestions.
Budget is below $1000.
I listen mainly to classical music and I want a warm signature, rich midrange, I'm not after tons of detail: I want to listen to the music, without analysing it..You have to listen Mozart's music with heart not just ears and brain :-)
In my short list:
Woo6 (but I have the feeling the 6 is "too neutral")
An XLR input would be great to use the balanced output of my Ref.5, but it's not mandatory.
