Only the music is in mono. Any clicks and pops and other groove noise is in stereo. Therefore, if you want to hear all the groove noise in mono, you need to use the mono switch.

all these disks are flat and quiet.
i have tried the mono switch on my preamp vs a mono cart unsummed as well as mono records played /w stereo cartridge unsummed and my preference is to not use that mono switch.
there may be a technical reason underlying this preference but soundwise the mono switch tends to dull the presentation.

You probably own a very expensive stereo cartridge in which the manufacturer has purposely asymmetrically damped the cantilever to create interchannel phase shift in an effort to enhance the soundstage. I owned a Dynavector XV-1 that was built that way and every time I activated the mono switch on a mono record, the cymbals and high-frequencies dropped down about 3-dB. It was very annoying and I finally got rid of the cartridge. Harry Weisfeld said he has encountered a lot of expensive cartridges built like that when he conducts Lissajous pattern oscilloscope tests that are supposed to produce a 45-degree line but produce ovals or circles instead. That's one reason I don't have much use for any cartridge that costs more than $1000. All my cartridges perform just fine when I activate the mono switch because they are built correctly and exhibit negligible interchannel phase shift all the way out to 20-kHz.

i have a Denon DL-102 and DL-103R. the 102 is a mono cart and is very lively going thru a Jolida JD-9. The 103 now goes thru a Hagerman Bugle. I previously used a Cornet which had a mono switch. Most expensive cartridge i've owned was the Ortofon Black.
So, which cartridge sounds dull with a mono switch? If it's the DL-102, then you definitely have a problem with your phono stage containing the mono switch because there should be no difference in sound one way or the other with that cartridge. A stereo cartridge with significant interchannel phase shift in the upper frequencies will sound dull when using a mono switch because the phase shift causes a reduction in high frequency output when the two channels are blended together. With asymmetrical cantilever damping, phase shift normally begins around 1000-Hz and gradually increases with frequency. This can occur with any stereo cartridge, but I've only measured it on my old Dynavector XV-1. All my other cartridges work just fine.

it occured /w my 103 on the Cornet. no matter because i use the 102 now.
