Got some HE5-LEs in today. Must say, these are really nice, balanced and quite neutral sounding. I am very pleased, and I have got to say that I definitely prefer them to the HE-500 I previously owned.

I am just using my Leckerton UHA-6 MkII, which does a decent job driving these.

Personally, never was into HE-6. I can agree it does a lot of things right, but I can't get over the brightness. It ruins everything to me.

One odd thing however happened on my Lynx HA61 and HE-6 - it is one and only time when I heard HE-6 as dark headphone. I did not hear any ringing or anything, and mid to highs was even recessed. Never saw that kind of odd change again with that amplifier or with he6. It was during some local meet-up, when we compared Lynx HA61 and Beta22 amplifiers. On Beta He6 sounds typical, but on Lynx it was like totally another headphone. But I can't say I liked new sound also. Really it was some very odd pairing. I wonder what happened there. Lynx have an amazing ability to control headphones, it just chains them down, and not allow a single wrong oscillation. Seems HE6 was not prepared for this, heh

To be pretty blunt, the HE6 sounds bad on the beta22. You need better amping comparisons.

Possibly. Overall its one of the best amplifiers I heard, but I indeed do not think it is the best choice for HE-6, I heard better. But then again, there are a lot of Beta versions around, and most of them are a bit different. But I'm not interested in either of those really.

I really found the B22 to be a tad sharp and bright in its signature. Not what I'm looking for in my sound.
