Got this from one of our new dealers that specializes in Headphones and Headphone amps:
"So just spent some time this morning with a few phones on the Bryston. The Audeze LCD-3, Beyerdynamic T1, Fostex TH-900 & because someone asked the UE11pro. I used the same set up from CanFest. PS Audio Perfect Wave Dac w the bridge card as the input, pulling data stream from our HP Media Server. I used Black Dragon Balanced Headphone cable to be consistent on the T1 and LCD-2. The Fostex is not re-cabled as this is not mine and has to go back to Fostex. I used balanced inputs form PWD and balanced output on the LCD-3 and T1. Others where via 1/4" jack.
The LCD-3 and the Bryston are ridiculous together. Just absolutely WOW!!!! I used all types of music. Volume control on the LCD-3 and Fostex where at about 9-11 o'clock depending on original track recording volume. And the T1 was at about 10:30 to 12 o'clock. The T1 and LCD-3 had the most bottom end weight and wow factor. However the Fostex was crisper, not bright just sizzled more. Man do I like the new Fostex. So much level headed across the frequency spectrum over the D7000. So clean. I would say of the 3 it was the best for critical listening. But the LCD-3 was just liquid awesome. So musical....The T1 was no slouch, it is still my vote for best bang for the buck over $1000. All 3 of these phones are fantastic choices for this amp. The great thing about Bryston gear has always been it's neutrality. None of their gear over colors the sound. Always very clean sounding.
So the UE11pro in low gain setting did not exhibit any hiss which usually happens when using such a high sensitivity monitor with a full size amp. The background of the amp is dead quite. I mean darker than dark quiet. There is not a lot of gain flexibility with the IEM but there is no reason you cant use it."
