I realize that this thread hasn't been replied to for a long time but I wanted to comment. I have been into audio for longer than I care to mention. I've owned KEF, B&W, Quad, SOTA, Linn, ARC, CJ, Theil, Pass Labs, etc. System price tags have ranged from $100 to over $80k.
My current system: Wilson Watt Puppy 8, Accuphase A-50V amp, Accuphase C-390 preamp, Accuphase T-109V, Esoteric P-05 and Esoteric D-05. Good but not overly expensive cables.
This is a very solid sounding system with little or no listener fatigue. Bass definition, sound stage, mid-range clarity, etc is very very good.
I recently took the opportunity to purchase the lesser priced word clock from Esoteric, the G-03x (used). It is wonderfully built, easy to connect and more importantly, superb in the added differences it made to my systems sound.
Bass definition - I didn't think it could get better than the combination of the WP8s, Accupahse amp and P-05/D-05 - I was wrong! The bass definition got even better with the word clock - Outstanding, articulate, defined, deep and tight. Zero bloat here..
Sound stage - huge improvement. Wide, airy, deep, incredible.
Highs - even my 55 year old ears can pickup on the subtle detail changes wrought by the G-03x. Highs are smoother, more natural, more three dimensional.
Overall system changes - as good as the system sounded before the word clock the system is now more natural and effortless sounding. Instead of thinking "damn that sounds great" I think about the person singing the song, picturing them behind the mike, etc.
The G-03x made a large improvement to an already excellent sounding system. Good stuff...
