Orthodynamic headphones, Anyone?

You'd probably have better luck at Head-Fi on that query. I have a pair of LCD-2's that I like very much, but they are not without flaw. That said, they're one of the very best headphones I've heard. I cannot speak for the Fostex as I've not heard them.

Jax2...what headphone amp are you using with your LCD-2s?

Asgard amp by Schiit Audio has a good review and cheaper than Burson HD160.

I wonder if Jax has a chance to compare the two.

Jax2...what headphone amp are you using with your LCD-2s?

I use a Woo WA6SE maxxed. It has very good synergy with those cans, but it is quite literally the only amp I've personally tried as I only received my LCD-2's in late September. Wait time is current around 6 weeks if you preorder.

I've not tried the Schitt Asgard nor the Burson. Schitt (pronounced how you'd hope not) is coming out with the Lyr amp which is a hybrid that is designed specifically with orthos in mind. They are currently taking preorders (just under $450 as I recall) and say they'll be shipping the first ones in March.

I'm going to be trying another hybrid; the Apex Peak Volcano with the Audeze pretty soon. I'll post a review and comparison over on Headfi (I am "Jax" there). That amp is also a respected partner for LCD-2s. Other than the Woo, which is excellent, no other amp experience to share. The LCD-2s do a whole lot right. The only place I can fault them, and this is to my ears, is that they have a fairly dramatic shelving down starting at 1K. The highs can sound a bit recessed in that regard. OTOH, I've listened to cans that err in the opposite direction, like the original HE5, and they require a Costco sized bottle of Aspirin for the headaches that accompany them.

Again, there is far far more input on the headphone-specific forums than you'll find here, especially on the Audeze. I'm sure the OP will find some input on the Fostex as well. As anything on Internet chat sites - take it with a bag of salt and make your own judgments with your own ears.
