Is your image centred?

I'm with Dan_ed on this one, this is soundstaging. Images are never always going to be centered, producers and engineers fool with this stuff all the time. If a hard or medium panned image was centered this would be wrong.

Also, these images often shift within a song, a voice on the right side may shift to the left side over the length of the song. Cds do this as well.

On the other hand, one may have issues with a weak center image, this is generally due to room interaction issues. It could also be setup or electronic issues.

I think Luna is experiencing mixing anomalies on lps. If he never has a strong center image then it is something else. The one thing I don't get, is why he doesn't seem to have this issue with his digital.

Hi Sns,
Thanks for your comments,
I do have good imaging with my set up. In fact, very good! I noticed there were imperfections in CD mixings as well but most of my CD collections are newer than my LPs. Well, only a small amount of CDs are like that. On the other hand, I noticed many of the Lps have problems. That is why I start questioning my analogue rig. I have to confess that I had abandoned my turntable for many years, I had it stored up. Lately, I have got a chance to buy a whole lot of good quality Lps of the 60s, 70s and 80s, so I am giving my turntable another go. May be the recordings of that time were the problem?
During these few days, I have been playing around with the set up and brought some improvements. Azimuth does make a different, Anti-staking only slightly. Even what is under the turntable helps with imaging! I was using some cones at the bottom but when I took them off and used a marble platform, the imaging is more solid. Some of the imagers that were way off before are now much closer to the centre. One interesting thing I found is that on those disks, the tracks at the middle seems less affected than the first few ones! (note: not all disks, some played good from start to finish)!

Your variations from track to track point to cartridge alignment issues, you should have very little variation within a single LP. I suggest if you're going to keep your present turntable for some time, get the MintLp Tractor alignment device, about $100, your deck will sound a lot better. I found it better than VPI alignment jig and DB protractor. Just google MintLp tractor.

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.

I have made some improvements again! It is the null point there was out! I found the template and reset the arm. The overhang may be out but I can’t do anything. The two albums that I listened last night were centred, not shifting around as I remembered. Just a little distorted at the last track. May need to fine tune something else?
I am getting excited!
One thing I noticed is that the sound stage has grown much wider. There is much more spatial information coming from the speakers. More music fidelity means more to worry!!!...Just joking, I am enjoying all the way. Will up-date again.
