Yes I think they do great with trance. They do well with pretty much everything though.

Thought I'd post my 2 hr impressions here as well, since this seems to be the main GP thread.. As I stated prior.. The amp seems to be more efficent power wise. More volume & drive on a lower setting.. Cleaner.. Much blacker canvas.. My DT48a with 50 adapter has no hissing at all.. I notice a difference in how instruments decay.. higher resolution, & they seem to slowly fade into the black ground better, more naturally, & more convincing then before, especially during complex passages. Just seem to extend to it's full 'cycle'. Theres a bit more resolve, & more to see so to speak.. The strengths of the amp all get a bump with the upgrade.. Bass is even more controlled with a bit more thump, & full body texture to it.. Not a great improvement in that area, but you will notice it.. & in general the amp is even more detailed, with a more effortless clarity. IMO, the upgrade is well worth it.. No down side.. Albeit, with my amp I notice the clicking to be loud, distractingly loud when I change the volume.. Before the upgrade, the loudness of the clicking was minimal.. I emailed Arn my concern.. Hopefully, it's just my amp & has nothing to do with the upgrade.. & isn't that much of a concern unless you constantly change the volume.. My main concern is the clickings loudness leading to some other problem. I already emailed Arn about this.

My DAC is a modded & balanced BC2.. & PS3 as my CDPer.. Which is excellent for a console, maybe it's the cell chip.. But runs circles around the 360 as a transport.. Have yet to try it with my Denon 5900, which is a nice improvement over my PS3 interms of lowered noise floor, more detail, & higher resolution..

Would definatly control the D7000's bass.. Reduce the 'bloat' many talk about..

Before trying the amp again, I plugged & replugged everything.. The clicking loudness is back to a bleep instead of a stomp in the forest.. Not sure what happened.. The upgrade really transformed my Technic Ortho's into a beast.. Makes me want to hear all my music again.

Thanks kool bubba ice, for the first hand impression about the latest iteration of the Headphone Pro. I have been sitting on the fence waiting to see if it is worthwhile to spent the money (shipment back to USA is significant). I was told this latest version is version 5 and the one I have is version 3.

Arn did say about the improved resolution and control - that makes me tempted. The volume pot related noise is worrying though.

After listening more & more.. The clicking gets louder when you raise the volume, & also seem to vary by headphone.. Less clicking noise with higher ohm, less sensitive headphones.. But, when I first took a listen I tried 2-3 headphones & all the clicks were loud regardless.. So the loudness has diminished, since I first got it.. like I said before, you only get the click when you raise/lower the volume.. I know, all Stepp Att have a small click.. The loudness just seemed to be more after I got it back.. slowly Changing the volume with a 1-2 second pause in between always diminishes the loudness to a small bleep.. I'm sure it's just my amp.. From my Business dealing with Arn he is always extra cautious & is a perfectionist. I wouldn't have any concerns sending it in.. Just the wait..

^ But you are in the USA. I too was intrigued with the upgrade but after doing the math did not carry on. The mod itself is cheap but shipping both ways + import taxes (real killer) made things too expensive for me (had to buy the Buffalo ).

Arn is working on my v5 right now. Hope to hear it soon.
I´m not inclined to worry about the clicking when changing volume. It´s what attenuators do.

Ofcourse, but you missed my point. Why would the clicking be louder after I got my amp back. I'm aware of clicking.

Because he changed the cirquitry of the amp maybe?

Interesting developments.

Not a deal breaker.. Just the first half hr it was really noticeable.. The loudness has seemed to subsided back to it's normal click in the past 2 days.. Maybe 'break in.' Not sure..

I just tried out the amp with my Denon 5900 being used as a transport. I would label the PS3 as being more 'fun' sounding, while the Denon adds a more dark, serious presentation to the music.. Better focus with higher resolve, especially the little details involving the mid range.. In one song, the p word was more prononced by a vocalist using the 5900.. The 5900 is better, but was expecting a bigger bump.. & a lot of it is preference based.. 'fun' vs 'serious.'

I really wish this amp was more popular. Would love to hear side by side impressions with the GS1 ans SPL Auditor. Arn is a great guy to deal with, and I wouldn't be afraid to put his engineering skills against Dusty, Ray, or Justin.
