First Impression (detailed ones coming - just bangin' away at another article I gotta get done to pay the bills):
Considering how much I enjoyed the liquid-like (sorry for the product name-pun there fellas) midrange textures of the OG Liquid Carbon:

- along with the extended, controlled bottom-end and, IMHO, crystalline highs - I have to say the Carbon has, thank God, met all my expectations, and is actually exceeding many of them! Unlike Audeze's LCD-4, in my limited time with it (sorry - had to ventilate freely for a second)...
The final product, compared to the units available for audition at CanJam SoCal, is superior out-the-gate when it comes to it's resolving capabilities. It's also got more dynamic bite in the lower-mids, and sounds more forward, more direct but it's not aggressive or harsh at all.
Admittedly, I haven't read back for other impressions, and of course I'll do so as always - but I like to scribe a bit about my first impression before reading anybody else's - like I do w/ gear and music reviews...
Now - I own (and YES, bought) Cavalli's awesome LAu - which is my current top-ranked reference for all my work. I never say "best" as peeps who know me realize - as it's all subjective cuz we're listening to music, no matter what, at the end of the day. But I've been around a long time. Cavalli's got this magic in the mids in his solid-state designs much like Tim DeParavicini does in his tube gear. It holographic, but not overly-analytical. It's resolute, but not too damn polite like so many audiophile systems. If I were to be pressed to try and describe a Cavalli "house sound" - which I F___in hate - but if pressed: I'd say his use of the word liquid in his products could be one of the most befitting product names I know of. All his amps, to me thus far - and the Carbon is no exception - exhibit this soulful, sweet sound, but its isn't overly colored or veiled in order to achieve some sort of sonic masking that some will love, and others hate. Cavalli seems to design like a true DIYer does (which is his background in headphone amps, let's not forget) - he seems to chase the music and not the latest curve or sound signature that's popular at the moment.
I'm a freakin' music addict who got into hi-fi and the music biz cuz I found out that higher fidelity enhances the musical experience.
To me - as of now (a full day) I can't think of another desktop amplifier, large-scale or transportable like this, near this price range that even comes CLOSE.
Just my 2 cents thus far. And I'm just using the lil' ALO KEY USB DAC (up to 32-bit/384kHz) - and this combo is so freakin' cheap - especially when I consider othee products in that range? It sounds like a no brainer to me.
I'm also using my MrSpeakers ETHER-Cs, Audeze LCD2Fs, and Sennheiser HD800s - all wired w/ Double Helix Cables Comp4 spore.
