I find it easier to focus on details with XTC. But it depends a lot on
the recordings. Some are horrible, others are wonderful. With
conventional stereo, I find that everything is equally smeared, like a
kind of glorified mono with a larger stage. I'm waiting for a pair of
very directional speakers that should (hopefully) help me enjoy
conventional stereo.

I have one recording of a Scarlatti opera that sounds very nice (and
detailed) with XTC. But usually I prefer mono for operas (listening on
the radio).

Why? I have no problem with off-center bass; I use 2 small speakers
with XTC and 2 subs with normal stereo.

True! I prefer mono or stereo for organ, or the real thing (in my
city there's a lot of good organs and a yearly festival)

XTC can do very strange things to bad stereo recordings, and there's
a fair amount of those in circulation. The worst I heard are recent
piano and harpsichord recordings that are considered masterworks by
critics. They were made to sound "glorious". XTC can reveal a lot of
bad tricks, and can destroy many mediocre recordings. Pop and jazz gigs
are a lot of fun with XTC. Anything with artificial reverb from the
80's is a catastrophe (what a terrible decade). Conventional stereo and
mono, on the other hand, are very forgiving.

Ambisonics enthusiasts are also using strong words; to them, anything
not ambisonics (or "blumleinish") is flawed, and simple questions are
often received as direct attacks. 

I use XTC to improve some of my listening skills, not to replace all
other listening methods. I have nothing to sell, and I sometimes use a
home-made physical barrier because it's still the best XTC method.

Presenting ambisonics as a scientific tool, a sound engineering secret,
or a surround system for museums or stadiums, are not very good ways to
promote it to home listeners, especially considering the quasi-absence
of ambisonics material in circulation.

If you could help me understand spherical harmonics, I'd be a "MAG
fanboy" in no time. The best didactic resource I found is a very
strange article titled "Notes on Basic Ideas of Spherical Harmonics".
It's so good that I barely understand 10% of it.
