Yeah I've actually read Mike's comparison of the two, seems to be the only one online unfortunately. Was just wondering if anyone else has heard them both. I plan on getting either the Studio Six or the LAu, though I am leaning toward the S6 right now. I plan to pair it with my Auralic VEGA and Auralic Aries as a source when that is released. Headphones will be the LCD-3, HD-800 & Alpha Dogs, I'm kind of leaning in the tube direction right now but this LAu interests me very much, just wish I could hear them both.
Darko:
I gotta say - (and this was said to me by my cousin Kenny, who've you met, my older cousin that works for Stevie) I have NEVER been as excited about an amplifier as I've been with the LAu!!
Not only does it sound like a hybrid amp to me (A link to
my Head-Fi review HERE - my full review coming at Part Time Audiophile w/ Scot) - really - when I first heard it I wanted to check out the Liquid Glass, but a couple was listening to it at CanJam last year. So, I went over w/ my own LCD-3s and checked out the LAu. Since my E.A.R has tubes within the chassis, I'm used to hearing a tube amp where I don't see the tubes - and upon my first track, I thought it was also a hybrid like the Liquid Glass, but, IMO, was way more airy, and downright dynamically engaging as all F___! Even with the Abyss - which I'm not a big fan of - I have one here right now - and its just not for me: KILLER bass, high end sparkle, but not much in the middle to me - and Michael Goodman, surprisingly, without knowing my opinion of it - told me he heard the same thing! But the LAu made that sing and my LCD-3s were just a musical time machine at that point!

I couldn't stop listening - even Alex Cavalli (now a friend, and a wonderful man) said to me "man, Michael, you were really lost in it for awhile" while I was auditioning the amp.
I told him that the Liquid Gold was the ONLY other headphone amp that reminded me of my E.A.R HP4 - and, that it MAYBE better in terms of musical engagement - and, what I look for most in an amp: it might've been better than the E.A.R in terms of what I call "emotive transference" - when the sound draws me in deep, and I get a serious emotional reaction to it - whether that means it drums up memories, or makes me tear up, you get the idea...
When Alex heard that, he asked if I'd like to review it. I said hell yes!!
When I got it installed at home I put it through everything I could think of (different DACs, cans, even switched out my Luxman deck for my VPI Traveler to try and see if it was really that magical) and it kept on grabbing me like no other headphone amplifier. I didn't just wanna review it, I HAD to have it! My wifey was ready to KILL me! I had a big spending year last year with audio - but, I sold some gear to make it happen - and I get excited listening to it EVERYDAY!!
I can't think of a higher headphone amp recommendation I could offer you my friend - I think you would love it - though I know our tastes in gear sometimes stray from each other - we both loved the Studio Six at Newport that year (after they fixed the issue from CanJam the year before)! And our musical tastes fall in-line often.
I think you MUST check it out!!!!
