Yes Tom’s city system. I was very impressed by the (big speaker-sized) diminutive 545s. They ran out of gas (bass flapping) but at SPLs much higher than I normally listen (or even comfortable). Tom’s room is quite a bit liver than mine, so I think the 645s will sound fantastic (at least I hope so!)
I also ordered the MA-1s. I’ll keep my eyes peeled for a used Benchmark or 2 as it might be nice to have a low-heat option to drive the SLs in the summer!
No new car for me for a few years!
