My personal listening experience on the TEAC line is largely limited to Esoteric single box X-01 Limited, X-01 D2, and P-03/D-03 combo players. Heard these players by themselves and with G-03 G-0S, and some 3rd party clocks. Clocks appeared to have significant audible benefits on the combo players, but negligible effect on the X-01 single box units if at all.
It has been suggested that this might be systemic, at least on Esoteric players.... Clocks may not be effective on Esoteric Single box unit in general... but I have no proof of this statement. Bill Feil has much more experience than I do on the whole Esoteric line, and perhaps can shed some light on the admittedly murky clocky issue.
