So good news...my Lyr shipped out today (thanks Jason for the quick shipping). I paid for Express shipping to Canada, so hopefully latter part of next week it'll arrive and I can hear my HE-6s (and LCD-2s for that matter) with this powerful amp.
FWIW, last night, I did plug my HE-6s into my 5.1 home theater Pioneer Elite receiver (thanks Rob for the suggestion) and I finally got a good appreciation for what the Hifiman headphones can really do. All I can say is wow....they are great world class cans and wow...they need a LOT of power.
I usually run my 8 ohm Energy speakers (with 6.5" woofers) at about -25dB for television and -15dB for Blu Ray movies....but I needed +6dB with the HE-6s to really get them going. And when they did...wow. Now if the Lyr can do that in that small package (my receiver is quite large), kudos to Schiit Audio (and based on Jude's review....looks like I will be quite satisfied with it).
