The McIntosh MQ108 is exactly what you are looking for. You can do a million adjustments with it between 20 and 1000 Hz. It was designed to resolve your standing wave problem. The MQ107 will do all freqencies but you have to swap out plug-in caps that come with it. Ljgj is right - hard to find now but I have seen them on ebay now and again.
Equalizer for McIntosh preamp - advice, please
I just received a McIntosh C200, which is an amazing preamp, but which does have no equalizing possibilities, as its smaller brother, the C42, does. It does have, however, a possibility tu use a sound processor with the preamp, which can then be turned on and off. As I do have a problem only with a nasty bass standing wave at 40 and 80 Hz, which is audible mostly with dynamic pop music, I think about including an equalizer. Does or did McIntosh produce such equalizers - maybe even for the bass only? And in general,
which good equalizers are there around? I am happy with the sound, and would not like to spend thousands of dollars line for a Tact room correction system. Any good equalizers with good bang for the buck?
