Why mono?


Can someone explain why the need for a mono cartridge when all I have to do is throw the switch on my preamp in the mono position?
Thanks

Mike: Thanks for the link. Unfortunately, due to the language gap but also what I perceive to be a near total lack of genuine attempt at explanation or justification on the part of the author, it doesn't tell me anything useful. But if you think their carts sound great for the money, that at least is something.

Thom and Jazzdoc: Again, all well and fine impressions, but what is the comparison (if you know) to simply summing the channels of a good stereo cart that you already own? The more the folks who champion mono carts post like the question doesn't exist, the more I wonder whether they know the answer, or even to ask the question...Maybe everyone ought to state for the record (sorry!) whether or not they even have a mono switch available in their rig (or summing Y-cables, but less good for the obvious reasons), because I realize that these days many don't.

Jrtrent: I also used to take advantage of channel/groovewall-selection capability with mono records back when I was using a C-J PV8 full-function preamp, and older McIntoshes had this too...Just like a mono switch (and also an absolute polarity switch), I'd like to see modern standalone phonostages incorporate this "L to L + R"/"R to L + R" feature (since linestages won't ever again, as mono is only really important for vinyl playback). It can also be useful for certain diagnostics even if you never use it for listening to music.
Thom, Mike, Jazdoc:

Would each of you state if your experience with variability in mono playbacks happens with newer mono reissues, with older original monos, or with both?

Thanx
Zaikes, the Herron line stages offer both mono and phase switching, even by remote. And there may be others, I know Joule-Electra has a mono selector on their linestage.

So saying linestages won't ever again provide a mono switch is not correct. Of course many brands don't. And a disturbing number (to me at least) omit a balance control as well.
My experience is with original, older monos.

Recently snagged a mono first pressing of Mile Davis' "Round About Midnight" from 1955 and it absolutely wipes the floor with my other two stereo versions.

Another recent purchase was Barney Kessel, Ray Brown and Shelley Manne's "Poll Winners 3" from 1962?...one of the best sounding LPs I own.

I also recently rediscovered some original Mercury Living Presence monos and they are spectacular.

Again (and similar to current vinyl releases) pressing and recording quality will vary.
I was with Win at Robin's and the Miyajima Mono is one of the best cartridges made, perhaps the best. It was certainly the best sound that I have heard from vinyl and at it's asking price that's pretty darn amazing
