I only ever heard the Kandy LIII and K2 with the B&W 684's, QUAD 22L2's and the M/A RS and RX6's
All were superb; the QUAD's again being the best of the bunch as I felt they tioned down the slight forwardness of the Roksan amps; the QUAD speakers are smooth so they suit the likes of Audiolab, Cyrus and Roksan down to a tee IMO
Unfortunately I havent heard the MS speakers with Roksan, just Audiolab, Rotel and NAD and for me they just didnt work full stop
