I agree with Elinor, it all depends how many Mono records you have. I have a mono switch on my K&K phono stage, it is a bit better with mono records. I am sure a Mono cartridge woulf be a bigger improvement, but think of the cost. Are you going to change the cartridge each time you want to listen? The only easy solution is a second arm, if your deck can accomodate it. Even a replaceable headshell, arm wand, needs VTA, tracking weight adjusted each time. The cost of doing it properly is'nt cheap.
