Harmonic Resolution Vortex vs HRS Nimbus Couplars and Spacers

Hello Audiogon members  - and yes I am going to kick start this old thread of mine again as Uncle Sam is going to send me some money back on my tax return. I am looking at the HRS Vortex's again and there does not seem to be a lot of press or any conversations for that matter here on Audiogon about this product. I would like to hear from members here on what their thoughts were on this product and if it did replace their HRS Nimbus Couplars and Spacers. Thank you.
