Og det som i siste instans endelig skal lede til at dette 25-år gamle slagordet går i oppfyllelse er ei supernøyaktig klokke og ei ekstern, totalt støyfri strømforsyning til klokka som gir den optimale arbeidsbetingelser for minimalt med jitter. Teac har jo levert sitt bud på ei sånn klokke for bruk mellom drivverk og converter. Pris ca 100.000,-. Allen Wright og Vacuumstate i Sveits vil snart levere et bedre produkt til en mye lavere pris.
En kar som er til troende har lagt ut en lytteomtale av den snart produksjonsklare nye power supplyen til "superklokka" til vacuumstate. Det svært interessante for min del er at jeg har den samme Sony SACD spilleren selv, med omternt de samme modifikasjoner. Og jeg forstår utmerket godt hva mannen ønsker å formidle i sine lytteinntrykk. Og det er en sånn type digitallyd som vil få den siste Lp-freak til å omvende seg til digital! ;D
A month or two back I installed the latest modification to my Sony 940 player from the fertile minds of Jo Rasmussen and Allen Wright. Joe calls this the "terra firma mod" and I supect Allen will call it "level 7".
In rough terms the modification involves an innovative new power supply to power the VCXO in the machines modified by Joe and VSE. I have my self installed every mod VSE have come up with for my machine and each time it has made an appreciable and sonically worthwhile improvement, not just a difference.
This time I believe the mod is a breakthrough in digital sound, at least for me. Those who have heard the level 6 modified VSE machines will know they are great but I have to tell them that they haven't heard anything yet!
There is an improvement in definition across the entire spectrum but while this sonic improvement is important , what is more important is how the machine loses the last vestiges of what I can only describe as a "mechanical" presentation, which I have heard in every single disc player I have heard until now, and replaces that with ease. Music simply breathes; expands and contracts in volume without strain, is achingly pure yet full bodied. I am now hearing more than ever but without any sense of etching or overemphasis of detail. SACD's on this machine fullfil the promise of the medium, and surpass what I had thought possible.

Det er sånne type lydforbedringer som Rob her beskriver, jeg oppfatter som utrolig spennende, fordi dette definitivt gir deg større musikkglede.
Selvfølgelig blir jeg igjen å sende spilleren min ned til Sveits for oppgradering, når denne modifikasjonen blir kommersielet tilgjengelig. Og denne klokka kan brukes på mange spillere.
Fra Vacuumstate sine nettesider:
Vacuum State has manufactured and sold our Reference MasterClock
Module (RCM) for SACD & RBCD players for some years, and it
certainly contributes to the sound of our Upgraded players. But never
wanting to rest on our laurels, we have made some fairly major
improvements recently.
These relate mostly to the power supply for the clock itself. We have
always used a completely separate power supply for the RCM and
now have focussed on making it as completely free from noise as
possible, as any power supply noise adds jitter to the clock signal.
A further advance is that we are developing a new, unique clock that
will be in a completely separate cabinet, and will feed the player by
matched coax cable using BNC connectors.
This allows us to make an ultimate power supply without any need
to worry about the space or temperature limits of having the clock
inside the players case. This of course allows us a completely free
hand with the clock design, and take it several levels ahead.
Esoteric make a $15,000 (!) external clock, and while it has great
reviews, we believe they are going in the wrong directiontheir
rubidium source may have stunning long term frequency accuracy,
but digital audio needs ultra-low short term jitter, not GPS satellite
long term frequency stability. More details on our website soon!
