Many of these posts (such as this one) suggest that the easiest and least-expensive way to accomplish this (if your amp/receiver/preamp doesn't have a mono button or you're not using a mono cartridge) is to connect the turntable to two "Y" adapters connected together — one male-to-female, one female-to-male. Most of these posts go on to suggest that doing this results in better audio quality and reduced noise (compared to playing mono records in stereo).
I tried it today for the first time. I do notice that the surface noise of the record is no longer in stereo, and the music seems to be perfectly centered, but I'm not really noticing any other improvements in audio quality... and although the surface noise is now centered, it doesn't seem particularly quieter to me.
Am I doing it wrong, or is this just a case of the technique not living up to the hype?
Where does your mono summing device go in the audio chain?
Between the TT and preamp or between preamp and amp input?
Putting the summing network between the cartridge and phono stage gets the phono stage out of the equation.
