In Reply to: RE: REVIEW: Vacuum State Electronics VSE modified Sony SCD-XA5400ES with Terra Firma Lite SACD Player (Modded) posted by Disbeliever on September 13, 2009 at 05:12:34
Certainly half of the Upgrade would be pointless, because it's a completely new audio section, and if using the HDMI output, that would be redundant.
I believe the TerraFirma clock would improve the sound, even from the HDMI as it is far better than the SONY clock, and sounds it. Jitter numbers are basically meaningless in context, as they are all measured differently - and it's not the DAC's jitter that we are focussing, it's the clocks jitter.
But I have no way to test the HDMI output, and certainly zero interest in buying a SONY receiver to use it when I have $35,000 worth of state of the art tube electrocnics to feed the Upgraded 5400ES analog signal into.
I truly doubt if a receiver could compete...

I HAVE NOW HEARD FROM A DIGITAL EXPERT THAT THE SONY CLOCK IS EXCELLENT AND IT IS VERY UNLIKELY THAT ANY OTHER CLOCK WILL IMPROVE THE PERFORMANCE VIA HDMI HOWEVER PROOF OF THE PUDDING IS IN THE EATING AND THIS DOES NOT TO POSSIBLE AT PRESENT>
...the SONY clock in the 5400ES is absolutely BASIC, with a cheap 50 cent xtal driven by a logic gate contained in IC152 in a very conventional two capacitor bridge network. This is obvious from the schematic on page 30 of the PDF Service manual.
How any "Digital Expert" can consider this to be good is beyond me, and many alternate clock manufacturers, not just Vacuum State, have made a good living from suppling much advanced clocks to replace this minimalistic setup in a wide range of players, not just the 5400ES.
Your opinion is your opinion, and maybe someday you will get your hands on an Upgraded 5400ES to test in your SONY receiver setup. Then you will know if it is an improvement or not - until then your comments are just OPINION!

Perhaps you will be good enough to let us know the jitter figures for your Terra Firma clock compared with the low mesured jitter by HFN & RR of ONLY 121 psec CD and ONLY 34 psec for SACD for the Sony BASIC clock ? regds Disbeliever

... to be unimportant if the sonic results are there.
Our basic clock has a published jitter figure of one (ONE!) picosecond, if that's relevant. And that's before it's powered by our ULTRA low noise powersupply.
There is no point in arguing numbers, as they were proven to be irrelevant to sonic results years ago. Remember the battle of the low distorion solid state poweramps of the 70's - 0.001% against 0.0011% etc etc, and all sounding ugly!
But we plan to have an Upgraded 5400ES in England with our UK distributer soon, and maybe you can borrow it and test it with a HDMI setup, against a stock 5400ES. I am not able to make such a test, but would be interested in your feedback.

Hi Allen
I shall be most interested in comparing your modified player with my stock XA5400ES via HDMI in my system and look forward to hearing from your UK Distibutor . Apart from my Sony receiver I have a very high quality stereo integrated amplifier and room voiced or room compensated transmission line speakers . Regds. Gerald Bearman
