Heymikey, I have tried the Ultra SSs and the Ultra Fives under both Tidal Contrivas and BMC Arcadias. I am on a suspended wood floor with no carpeting under the speakers.
The SP Ultra SSs were dramatic, almost unbelievable. The sound stage took on great realism. I bought many more for use under components. Then I went to CES where the Ultra Fives were introduced. I heard a demonstration with the Fives substituted for the SSs. I took home eight Ultra Fives. On both speakers and my amps the SP Ultra Fives literally made the SP Ultra SSs sound broken or in effective. It is like going from a $5k amp to a $10k amp and similar for speakers.
I should note that I reviewed both and said most of this.
