Luxman M-10X Stereo vs. Mono or C900U


Anyone with the M10X can quantify the difference in stereo mode vs. monoral  mode? 
I currently have a Lumin T2 which I can use to connect directly to M-10X and use it as a preamp. The speakers are Kef Blade One Meta.  Is it better to put the money toward a second M-10X and run them in mono than getting a proper preamp C900U?

You want a true mono cartridge that reacts only to horizontal movement in the groove.

Any vertical movement is ignored. There is a surprising amount of vertical movement in true Mono LPs, new or old: small warps, surface scuffs, dust/dirt in the grooves, ...

When I sell Mono LP’s, I let buyers know: playing Mono with a Mono Cartridge: surface scuffs are not that apparent, a musical experience results,

but those surface scuffs (and ...) are definitely louder/detracting when playing using a Stereo cartridge. (even using Mono MODE on your preamp does not quiet it down the same).

I have some very old mono LPs. Playing Stereo Cartridge Preamp in Mono Mode, they were like a history lesson, not enjoyable, wouldn’t play again. Now, with my Mono cartridge, they are enjoyable, I play them for me and my friends.

another day I awake feeling smarter than many, only to have my bubble burst before I reach the coffee pot.

Lol. I ended up buying another M-10X and preordered the C-10X. Using a loaner C-900U with the two M-10X monaural mode.
