Help Choosing Headphone Amp for Audeze LCD-2

Ron I was about to head down that rabbit hole / merry go round in search of a headphone based system and thank goodness I happened to come across Bob Katz in-depth review of Audeze LCD 4 and the Mjölnir Bipolar mk2 amplifier .
Being familiar with Katz’s engineering work over the decades and having read some of his published books I’d take Katzs word over most anyone.
However I opted for the Audeze LCD 4Z instead of the standard LCD4 and of course the Mjölnir amplifier which retails for $2,100.00 , it’s truly a great match with Audeze phones .
 
More information and back ground can be found about Mjölnir Audio along with other premium builders of electrostatic and dynamic headphone amplifiers on Headcase forums .

Thanks @in_shore I will give that a look see as well!

We've been using the Bryston BHA-1 as our reference headphone amp for Audeze demos. It's also too bad the OPPO HA-1 was discontinued, because its balanced headphone output is excellent with Audeze.

I've heard great things about the Moon Audio Dragon Inspire headphone amp, and if it's anything like the Dennis Had built Inspire SEP power amp I have, it's likely to be real good. Plus, it looks cool.
