Thanks for all your comments about amp pairing with the LCD-X. This next question will probably show you why I'm a Jr. Head-fier.
I was all set to order the Bifrost/Asgard 2 stack, until I read comments about how great the X sound with the Gungnir/Mjolnir stack. I understand the difference between the amps and the X are rated for 1-4W. However, I don't understand the difference between the two DACs. As the G/M stack is double the price of the B/A stack, I wanted to ask for a little more input. Is the G/M stack worth the extra money?
Thanks also for the comments about the Lyr amp...
All the Best -
Gungnir/Mjolnir setup is so called 'balanced setup'. Here is an excellent explanation : http://www.headphone.com/learning-center/balanced-drive-faq.php
I have a nice balanced setup with Onkyo, Dacmagic + beta22, only problem is I just cannot sense any difference against my single-ended setup, but others say/claim they do.
One thing to consider is that, Mjolnir do not have single-ended output. It means headphones that do not have balanced out (read: a lot of them without warranty-void recabling work) won't be usable with Mjolnir.
It means while LCD-X will work with Mjolnir, your Edition 8 won't.
Just go for fully upgraded Bifrost/Asgard 2 or equivalent performance discrete solid-state amp, as far as I concern there aren't much difference between fully-upgraded Bifrost and Gungnir except Bifrost is not balanced-output DAC, and Asgard 2 is really excellent even against higher-priced ones including Mjolnir itself.
I do have B/A2 combo myself now and I use it more than my balanced setup, since it is much easier/convenient to use.
