kubla, no, the o-l motor-p/s was *not* a "whoo-hooo! Whoopeeee! ai chihuahua!!" kind of an upgrade. ;~) more subtle, for sure, but still worthwhile, none-the-less. better pitch definition, quieter background. i tink it was worth the money, especially seeing that the original motor is ~20 years old, and mine was quite noisy - who knows how much longer it wooda held-out.
re: "whoo-hooo! Whoopeeee! ai chihuahua!!" - if yu've not experienced this quality analog in yer home system, or are only listening to digital, even in the form ya have now, i predict ewe *will* get this type of reaction from the rig yust as it is. this was definitely *my* reaction when i 1st hooked-up my oracle, even w/the grace 727 tone-arm, which wasn't really well-suited to my 11-gram ortofon cartridge. :>) (i'm now using the o-l modded rega rb-250). my prewious 'table, a highly-modified cj walker cj-55, w/a re-wired sumiko premier ft3 arm, was no slouch in its own right, but the oracle blew it away... and, to be honest, even if it dint, i'd have been happy (as long as it wasn't *worse*!), yust cuz it's so cool-looking, & i've always wanted one, since i 1st saw one when they came out. the fact that it *did* make such a staggering improvement was *way* cool - someting that even amazed the wife... ;~)
happy listening, doug s.
ps - i dunno anyting about the goldmund mat/clamp; i got the upgrade oracle mat also, when i 1st bought the 'table...
