I auditioned this one tube preamp that sounds really good on a speaker system which is not designed for headphone use. I am wondering if I could feed the RCA output straight to a headphone using a RCA pair male to 1/4" female cable to my HE-6. Here are the specs of the mentioned tube amp:  ...

Saw these two on a second hand store, which is better balanced? Like, I want to listen all kinds of music on them, thanks.

Can someone suggest the best headphone and amp rig out there for the following preference? My music pref: Classical, Orchestra Requirement: Not too much on extreme highs (18~19kHz), Huge and realistic soundstage reform, detailed, not too much bass; instruments have their own "space" Yeah...

Can you guys suggest some good connector for my PA2V2?

Man, I bought the PA2V2 from Ebay and the first thing I do of course is plug it in to my Iaudio M3. Whoa......crap. My super.fi sound worse than anything at that point. Is there anyone who have experience using this amp? I want it to sound better, but is there a way? Peace out~
