How good is Benchmark DAC1 comparing to......

The "adjustment" is aftermarket and even then its not much.

I'm with Zenguy. Should we wait?

No, don't wait to purchase a DAC1 because of the forthcoming "adjustment". The "adjustment" does not in any way change the DAC1 itself.

Dne, am I right in assuming that the 'adjustment' is one of the permutations of the settings discussed in the user manual, as opposed to involving an adjustment not discussed in the user manual? That is, the 'adjustment' is some combination of front toggle, back toggle, rear volume calibration, internal gain setting, internal bypass of input select, etc?

I can't quite see the mystery and reason for the secrecy, which in one email I have received on this implies a commercial motive behind the secrecy. Can you please clarify?

That is part of it but there is some more.

I can certainly understand all the interest. But, I have to say that I didn't discover all this and so I really can't comment further -- the other party will have to do so. I don't know all the facts here and I have nothing more to add so please don't address any more questions to me on this subject. Sorry.

Hopefully all will be divulged soon.
