Hi Michael,
You described exactly what I heard about 17 years ago from the first true audiophile's system I experienced. That was tube amps, planar speakers, very heavy turntable and hours of empirical tweaks on his part. There were tape marks on the floor, he told me to lean back on the sofa in exactly this spot, then pull my head forward until.... No missing it when you heard it! I always thought the super-sensitive sweet spot was a planar speaker issue until your post.
The first week with my M3Ti's has been impressive enough. The Avia disc was already on order & now I'm getting impatient.
Many thanks.
