Just a quick reply on the initial responses.
My post was simply on whether Trifield really sounds better than stereo, which seems to almost be taken as a given in post after post on this site.
I would agree Trifield improves the stereo image, particularly if off axis. While this is clearly a plus, what I was getting at is the articulation of instruments and voices does not appear to me to be as clear with Trifield as with Stereo direct.
Bass in particular does not appear to be as articulate rather than just loud which makes me think it may be more what I might describe as a phase masking issue that just turning up the base setting does not completely satisfactorily address.
Looking forward to more comments...
