The Clux was available in two flavours, 3x or 4x SPDIF.

Whilst few people actually have the ability to fully utilize the 4x it might help folks to know which this one is.

Good luck with the sale.

Sooloos, Roon, G series (with LPS upgrade), 800 series (with LPS upgrade), HD621, AC200, Prime and PS, DSPs old and new.

Purdeys, Moke, Leica, 'Blad. Only the best.
