I am fortunate to hear one regularly as the main Source an the System of the Owner which is all Valve with Stacked ESL 57's. I know this system very well and have heard it numerous times with different CD Sources and the odd added on TT.
I have also heard the Acute in use in a few other Systems using Valve Amp > ES Loudspeakers and Cabinet Speakers. Where it maintains being extremely attractive in use.
I have heard what can be achieved using a selection of configurations for the Valves in use.
It is a exceptional CDP, used via a Pre Amp or used as the Pre Amp-VC
The regular group have also heard it as a DAC only and as a XLR into SS Amp's and maintained their great appraisal for the Source.
