Well as I mentioned in some detail in the previous thread on this subject, as far as I'm aware you would have to send your SCD-1 to Germany - sounds radical I know but a friend who got his 9000ES "done" said, whilst it took a few weeks before it was returned to him, the results were/are remarkable. There are plenty of threads discussing vacuumstate on the highres forum on audioasylum [URL=http://www.audioasylum.com/forums/hirez/bbs.html]www.audioasylum.com/forums/hirez/bbs.html[/URL] there are also a few pages I also came across an interesting account of someone who had the well known Richard Kern (audiomod) mods undertaken to his SCD-1, the account describes a comparison between the Kern modd'd one a vacuumstate version and the Meitner SACD player and the vacuumstate SCD-1 was considered the best (in the opinion of the three guys running the comparison). I cant yet re-find the link or the page though unfortunately. I dont have any affiliation with vacuumstate so I would recommend you contact Allen Wright (see their website) if you want correct info.
