It seems they punch above their weight, so to speak!

Not in my budget, but if they were, I'd be racing out the hear them.

They seem like a cool benchmark product, did they go back or are they sticking around for more comparisons?

Really, a pretty exciting product.

Added: JA1's measurement section was also pretty darned interesting. Just don't let Golden Sound get hold of these. ;-D

... the measured output power at clipping was 1322W @ 8Ω and 2250W @ 4Ω.
They also made instantaneous peak power measurements which resulted in outputs of 1640W @ 8Ω, 3130W @ 4Ω, 1790W @ 2Ω, 960W @ 1Ω.

They also tested the S5 two-channel version ($7K) and the measured output power at clipping was 670W @ 8Ω and 1170W @ 4Ω.
Instantaneous peak power measurements were 691W @ 8Ω, 1390W @ 4Ω, 1780W @ 2Ω, 902W @ 1Ω.

"Also on the back panel is this warning:" "Speaker impedance 4 ohm minimum." Uh oh: According to John Atkinson's measurements, the Wilson XVX "remains between 2 and 4 ohms for almost the entire audioband," with a minimum value of 1.5 ohms between 310Hz and 340Hz. He concludes, "The Chronosonic XVX should be used with amplifiers ... that don't have problems driving loads of 2 ohms and lower."

Doesn't mean they will sound crap, just won't get the "very best" out of them at those impedances, like say a Gryphone Antillion will. Which supposedly doubles down to 1ohm.

Cheers George
