Is your image centred?

Perfectly normal, and if you increase resolution you will hear this even more. Vinyl playback is not perfect, but it still makes beautiful music. So if one insists on rock-solid, pin-point images there is always the IPod. ;-)

Stringreen,

I agree with you regarding most every classical LP I own, which isn't much, and with jazz. But with most other recordings (pop/rock/country) this shift in image and soundstage happens most often. Usually it is done as a gimmick. At least that is what I experience, even after Minting.

Analog could be more fun but also more hard work to get it right!!!

Yeah, well. Where ya' been? ;-) Digital does a few things well. In some cases, very well. But to get that real, you are there sound. Analog is the way to go. For the record I do work at and enjoy both mediums.

A mono recording is good for helping to set azimuth, and maybe trouble shooting a system problem. But I suspect that for someone who seems to be sensitive to imaging, you probably won't enjoy mono. Hopefully, in spite of all of this mind trick image stuff that some place so much importance on, you will find a mono recording of music that you enjoy. Regardless of the medium that is still what all of this is about.

Couldn't improper azimuth shift an image?

It may, but it would have to be grossly off. Usually, azimuth just makes the image sharper. However, that is not really what Luna is asking about.

Raul, when the image shifts differently while the LP is playing and differently from LP to LP, to me that does not act like loose wires or worn caps. Have you never heard a singer's voice centered at one point in the soundstage and then shift to somewhere else during another passage of the song? Not just LPs, I have many CDs that are mastered this way. But we don't really know exactly what Luna is experiencing without hearing it for ourselves, so it doesn't hurt to check everything.

Luna, changing the interface to your table and hearing improvements does make a lot of sense. Different materials resonate in different ways and can sometimes smear the notes causing all kinds of havoc. I've been through that with hard maple, granite, Stillpoints, etc. All tables are different so it does quite often require experimentation. For me, about 1/2" of aluminum as a shelf has so far worked the best with my table.
