I had a $6 k Krell vanguard and bought the Marantz ruby integrated .
i know the musical Fidelity’s latest 6 , it is fast and pretty musical
but the KI Ruby is for sure more fleshed out and involving especially instrumental
depth and soundstage depth.saying it is harsh as with all quality equipment these amps take a solid 250
hours to fully run in ,and for sure use a quality power cord , as well as replacing the 2 fuses in there which is a noticeable step up in resolution .and being in Audio for over 40 years ,observing the matched parts quality is much better then MF for sure the preamp is also active with seperate power supplies ,not passive the KI is a dual mono design direct coupled to the Copper speaker terminals, just look at the pictures,the others use cheap brass connectors also preamp is totally isolated and ,volume is regulated microprocessor much better resolution then the plastic carbon volume pots on the MF and copper chassis is $$ for its anti magnetic isolation they put in over a year designing it and voicing it it is a bit tube like but with SS grip and dynamics
the Ncore modules put out not the stated 100 ,actual 170wpc into 8 ohms 280 into 4 and the negative current feedback design truly controls Loudspeakers impedance loads. We played maggi 3.7s to the Amphion 3S monitors with great control and musicality.Ken Isawata died last year
just after retiring after 40:years with Marantz . This was his last effort,
and a very good one at that.RIP Ken, a true Audio pioneer.
