Today I was listening in my room without the AC being on and as many of you know, it has been fairly hot here in S.Calif. I quickly noticed that the imaging seems to suffer a little ( never mind the listener, LOL) depending on the climate in the room. I have noticed this phenomena before, usually at audio shows. Since we are about to be experiencing some MAJOR heat here in S.Calif in the next few days, i wonder how this is going to impact our listening sessions. ( I for one, will NOT be using the system during this time). OTOH, running the AC and listening at the same time is an option, BUT who wants to hear the AC fan/ vents while in the listening session. ( One of my pet bugaboos at many hotel rooms that are used for high end shows). To climate control or not, that is the question...
