My entire system took a giant leap forward with one change...
I have Emerald Physics 3.4 OB speakers all components were in a Solid Steel vertical rack for 2+ decades, but have long thought about replacing it and going horizontal, thinking the tallish vertical rack was screwing with the sound stage. The opportunity finally arrived early this week, as I was able to pick up a sold maple table top (5 x 2 x 2") locally. OMG the improvement in overall sound is so much more organic and 3 D then it ever was in the rack. This of course affects my 6000 CDT. Now I am aware that owners of the 6000 moved up to the Pro-ject RS2-T and report how much better it is, and I don't doubt it, but going horizontal on solid maple is for me a giant leap in enjoyment
