Is phase control switch a deal breaker for you?

In all of my years in the audio hobby I have only had
a phase switch once. It is on my recently acquired Octave
jubilee preamp. I have experimented several times
and have concluded it makes a difference on certain
material. For example, I was playing an LP
that I thought sounded kind of thin and closed in
Now for most of my lp's, they do not exhibit this
anomaly. This one LP did and I reversed the phase
on the preamp and what a difference. Generally speaking
most music can be played back without thinking about
phase settings. Every once in a while you come
across a situation where you wish you had or
just carry on. The fact that I did not use a phase
switch before does not mean that I do not
want it when I need it. It is like having a spice
or something of that nature. You probably could live
without but if you had, use it. So, a phase switch
is not a deal breaker for me, but, since I have
found usefulness in having one, I may be more
Inclined to seek out that option in any future
upgrades, which at this point I do not see happening
to soon.
