Opinions on Esoteric clocks ......

Hello Garebear,

Correct, the external clock cannot improve the jitter of the internal clocks; it locks them to the same reference frequency.

I understand that frequency stability/deviation specification of external clocks is extremely tight (this is why they are so expensive) and there is benefit using them with multiple synchronous digital audio components, but that has nothing to do with improving the short-term stability/jitter of the internal clocks, which is critical for optimal D/A conversion.

Technically, this is all pretty much over my head. All I can comment on is what I hear. So I have to take issue with the comment above that "if there was a clock output from your P05 so you can feed D05 with it, you wouldn't need external clock because the benefit would be the same." Unless I misunderstand, this seems to be saying that if you can slave the transport's clock to the clock in the DAC, the result will be the same as with the external clock. (If I misunderstood, sorry.) When I ran the P03 and D03 by themselves, of course the P03 was slaved to the D03's clock. The very substantial improvement when the GOR-b was added was over the P03 slaved to the D03.

......and let's not forget - ahhhhh - the cost of 2 BNC cables - and the cost of another power cord which from what I have been told does make a difference on these clocks. My system is witred with Purist Audio 20th Anniversary's ...not cheap !
