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
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?
