Von Schweikert VR9 SE Mk2 new foundation amps and Ultra Masterbuilt internal cabling. I've heard maybe 1000 audio systems at shows, dealers and homes. The Ultra 9 and 11s were magical with my LPs and CDs rendering the performers in front of their mics as mastered (classical and jazz acoustic music). Coupled with superior dispersion, sit, stand, lay down and 90% of the center seat sound is heard, with a wide seating area. I heard four other earlier versions and my friend's VR35 export. I can't afford the Ultras but purchased the best version of a then 8 year old SOTA speaker. So satisfying. Agreed to purchase prior hearing them, auditioned with my nearly future pre-amp (Lampizator Horizon DAC, older EAR 912 pre), future amps (Westminster Labs REI) and a Lumin streamer. The dynamics of that combo was absolutely stunning, as real as live acoustical performances.
