I have LS60 + two KC62 subs, Marantz SA-10 SACD player, Manley Chinook phonostage, Yamaha PF-800 turntable with upgraded Analysis Plus Silver Apex cabling in my secondary system.
My primary has Revel Salon Ultima 2, Parasound JC2+ monoblocks, McIntosh C1100 preamp, D1100 DAC, McIntosh MCT450 transport, SME20/3 turntable with HANA Red cart and Manley SteelHead phonostage.
Bottom line: I have never found KEF LS60 lacking in resolution, missing bass (even with subs off) and/or not musical comparing with the primary system. Phenomenal speakers - and not just in their price range! I can happily live with this system as a primary one. Internal amps, speakers, paired woofers, cabinets, internal DAC, and DSP are designed to work together - which cannot be achieved with the separates in the similar price range.
P.S. I had some issues during initial setup - but the resolution is simple: one needs to make Google Chrome a default browser in your Android phone settings (omission in the manual).
