Congratulations on an exceptionally beautiful plinth under your 301. The rest of your system is very well matched, and must provide nothing but hours and hours of rewarding listening pleasure.
I built my own Garrard (a 401), wall-mounted it, put a sandbox under it, and used Edensound Bear Paws under it. In your case, I think some isolation might be in order, between the granite and your plinth. You can experiment by trying out some inexpensive Vibropods, and see if it helps.
That would isolate your table from any energy transfer from the granite to your plinth. Might be worth a try.
Best of luck, regards,
I may try the Vibropods as a temp idea as they are relatively inexpensive while I do some research on others like the Townshend Audio Seismic pods. the ability to adjust height is a plus.
Any other suggestions ? I've seen a few doing searches but to be honest a lot of them out there are rather hokey looking and or plane ugly.
Daedalus Isolation Devices (DiD’s) is your answer. Contact Lou and ask him where best to use them...
I don’t know how he got to this certain combination of woods and metals in all the right place but they really are good --and I tried Stillpoints Ultras and many many others.
The DiDs do all the ’rights’ that other fosters do, with none of the ’wrongs.’
He also has them available integrated into a platform.
@glennewdick, that plinth looks luxurious! Superb!
I also use a Garrard 301 (restored by Loricraft) on a Birch ply plinth. I did not like the way it sounded isolated by squash balls or any such softer material. It sounded best properly coupled to the rack via Track Audio Footers. If you have an issue with footfall (suspended floors) then coupling would not be an option. I have no experience in decoupling though.
Thanks for the heads up noromance I've considered this already from a friends advice i'll be upgrading the bearing when and if I go to a heavier platter. I've been running it stock as for now and i'm quite happy i'm in the middle of other upgrades so mods are on hold for now.
I had the need to upgrade my phono section when I sold my Luxman and went to a SET 300b tube integrated amp. I'm also in the middle of having my wood guy bore another hole in the rear for another arm set up, 9" or 10" this time for the lighter weight carts. so lots going on.
I don't seem to get that effect but mind you my slab of granite is 165lb and sitting on a three legged stand with pin point isolation on every shelf. I also have the plinth on three pin points on top of the granite. That said I have my wood working guy boring another hole for a second arm and also making me a 4" think bamboo shelf i'm going to try under the table mostly for esthetics but may help in sound as well.
Yeah, years ago I moved my 401 off the concrete floor to my new oak table and was dismayed by the loss of ...everything. Sat it on concrete slab on top of oak and that helped. Switching to granite brought it all together. Adding steel points between granite and plinth snapped focus into shape. Can’t imagine a Loricraft plinth working well with those squash balls.
