mono vinyl- which way to go?

go both ways, it assures you of always having a date...

Bwaahhhhaaaahhhhaaa! That was great!

Before you decide on any two arm setup, I suggest extensively auditioning with one arm and then compare with the second arm mounted. However, if you really do listen to 90% mono then why do any stereo at all? There is no real benefit to stereo unless you're just in to mind games like the rest of us.

If you have a Phantum go with an extra wand.

Both wands must be made of the same material.
I did this with my 2.2 and made the mistake of ordering the second wand without making sure thay were both made same material. Ceramic wands at one time had 2 differant core materials. I had to sell my origial wand and buy a new one again so they would be the same weight. The original ceramic wand was 10 grams heavier than the new one.
I ordered the extra wand when I ordered my phantum so it would not happen again.

Then you can have both stereo & mono.
Thats how I did it.

while i do not listen to mono much(at all), the one thing i miss is an extra arm, by all mean if you can aford it, two are better then one.
