In the office went the more vintage pieces, where they complement the old boatanchor Collins radio gear (Mom bought those for Dad for Christmas the year I was born). A while back I rearranged the office, consolidating all the ham gear on one side of the desk, and adding an Ikea cabinet (clearly the choice of discriminating, yet budget-conscious audio mavens the world around!). I shortened the Ikea piece by 1-1/2 "units" to leave room for hanging some guitars on the wall. The wife approves of the aesthetics, so here is how it will stay. Oh and yes, the rightmost KT88 on the amp is popped. I think the power supply caps have finally let go on the 275, and will be replaced soon.
You and I are on the same wavelength I think. I've got McIntosh & Collins gear too (although I've sold off some of the Collins - the 30L1 and 62S1). I also have vintage Marantz components and would like to finish a comparable Audio Research system. You can't go wrong when you collect the best!
