I just got a Oracle Delphi Mark IV off of Ebay a few weeks ago. Much to my surprise (well after the surprise of bent suspension pillars) was a non-stock mat. When I took a closer look, it turned out to be a Goldmund. I also have an old Oracle rubber mat from my Oracle Alexandria. Haven't had a chance to hear the Delphi with either mat yet as I am now waiting for new pillars from Oracle. Perhaps I will post a comparision once I get the table up and running. I concur with the previous post, that it is quite interesting that Oracle has now switched current production to a mat that is at least superficially similar to the Goldmund.
Anyone ever use the Goldmund Reference Mat ?
Someone left one of these at my house.I know usually they just leave their sunglasses or car keys.Sometimes they just leave(Hooray).Anyway,the mat is about 5/16" thick made of carbon fiber acrylic.It is coupled to the platter with an audioquest sticky sorbothane sub mat.I put it on my Oracle Mark II,Magnepan Unipivot,Ortofon kontrapunkt,into Music Reference,Audio Research,Music Reference and finally to Acoustat 2+2.Certainly added detail.I played "Stagefright" by The Band which seemed a bit muddy to me last time I spun it.Clean and more focused now.Then i played"Nightwings" by Bucky Pizzarelli w/ Joe Venuti.This is a mid 70s flying Dutchman LP.A duet of Bucky on 7 string Electric and Venuti on Violin of course.Initial impression is very favorable to me.I had to raise the arm,but the Unipivot has VTA on the fly so no problem.The only problem is that the mat is so tall that the record is at very top of spindle where Oracle has threading which is of smaller diameter than spindle.Record needs to be centered visually.I'm working on adapting a spindle from junk turntable to heighten spindle .shouldn't be too difficult.Imagine I'll need to recalculate downforce with added heighth as well.Need to spin personal reference LPs to get bigger picture,but seems to have possibilities.
