Why do you need to wait 3 months to buy it? if you know you want it?
Do you plan to go in there several more times to look at it in the next months, see if it helps make up your mind?
It’s not that big a deal, just a preamp and a pair of monos that gets sold en masse around the world. It shouldn’t cause you so much anxiety and mental chatter.
I plan on buying a McIntosh system C12000 and 2 MC611 monoblocks in a about 3 months from this Stereo shop I have chosen. I’ve been to the store about 4 times over the past year and half to listen to various components trying diff equipment.
