Neuance or Z Slab shelf for Zoethecus rack???


I am buying a Z4R rack from Zoethecus. Is it worth the effort to go extra mile to get the Neuance shelves instead of the factory Z slab shelves??? I have heard different stories about both shelves' sonic effects. I am very confused and can't make up my mind which way to go. Thanks much for your kind inputs.

*but if you can, I urge you to try upturned spikes under the shelf*

And I did. And the benefit was not big enough for me to put up with
instability. Some of my components weigh under 10 lb with 20lb cables
attached to it. ( you get the idea )

At any rate, his new shelves are just as fine to be used as a stand-alone.

Or, perhaps, I can't hear that well. :-)
Ken claims the newer Neuances are 3dB quieter in addition to not needing upturned spikes. We'll see....
Does Ken Lyon of Neuance typically take awhile to respond? Realizing that he's presently heavily backordered that might explain the non-response to my weeks-old email inquiry, but several days ago I tried inquiring again via his website order-page & have still not received any acknowledgenment. Meanwhile the folks at Mapleshade have already processed & delivered my shelf order within the same timeframe. Perhaps some form of motivation (Neuance bribery) might help? I'd phone or write to Neuance but there's no contact information on their website.
Would some kind soul here please email me with the Neuance phone# & mailing address contact information? I'd really appreciate any helpful hints.
Hi Bob,
I just just saw this post and have resent my reply to your enquiry of 4-08-03,8:31 PM to which I replied the following morning ,in less than 12 hours of it's receipt.
I have not received any other communications.
Regards,
Ken
OK Mr. Lyon thanks I'll try again - perhaps I entered my email address incorrectly as nothing was rcv'd here; thanks for your repeat efforts that's appreciated. I'll try to use the Audiogon remailer this time. I left my order detail info. @home - my email is @work. best rgds, bb
