    No Secret
    Its a California Audio Tempest 2 [Special edition] It has a true all valve directly coupled output stage, and even uses valves for the current to voltage conversion from the Dac chips.
    Its easily the most analogue sounding player I have heard, whether thats a good or bad point" depends on ones personal taste I guess.

    I think this is a very critical point and I'm glad you brought it to everyone's attention. It hadn't struck me but this is a very real restriction on digital performance.

    Interesting. So the argument kind of goes like this: recorded sound ends up being stored as a signal that could be used to reproduce the original sound. That signal is very simple. But hold on, there is a temporal dimension to it, so it is actually very complex.

    That is the most confused argument I've ever heard. It must be either simple, or not simple. It cannot be both simple and not simple at the same time.
    Don't you just hate it when you cannot detect where the post ends and a signature line begins?

    Actually the digital element is the easy bit. The majority of CDPs and DACs sound shit because they use 10p opamps - 50p in posh ones - in the output stage. Sort the output stage, which I would say is 50% of the overall impact, and the chip is maybe 10% of the overall sound, most of the the remainder being down to power supply. The vast majority of crap digital is actually just crap implementation.

    I'm prepared to agree with this.

    "His PhD investigated radial velocity using absorption spectroscopy and doppler spectroscopy of zodiacal light using a Fabry–Pérot interferometer based at the Teide Observatory in Tenerife. His research was initially supervised by Jim Ring,[2] Ken Reay[2] and in the latter stages by Michael Rowan-Robinson.[1] He graduated at the awards ceremony of Imperial College held in the Royal Albert Hall on 14 May 2008.[citation needed]"
