Mono Switch in Phono Stage


Since most of the mono carts are exorbitantly priced, I wanted to get a phono stage that offered the toggle switch that allows you to choose mono or stereo instead (i.e. ModWright or K&K...) Does the sound from the mono-switched phono pre compare pretty favorably to the mono cart sound? Or is it not even close?

No, it is not. There are some economical mono cartridges such as Grado and Denon.
I don't know much about the Denon, and am curious, but I generally don't like the Grado house sound. Has anyone tried the Shelter mono cart?

Plus: can the owners of K&K, ModWright or Art Audio phono stages comment on the usefulness of mono switch function, even if it's not to compare w/ mono carts?
I am just about to fit the mono switch on my K&K, I will report back. If anyone is interested, you can retro fit it to older models
