JonM Posted November 13, 2021 Share Posted November 13, 2021 (edited) I have finally ordered my Quatros and M5 amps. While they are being built, since I have nothing to do buy study and read, I will occupy my time by preparing the house and room for them. Maybe I can help add content to the forum too and help someone else. Job 1. Minimize HVAC noise This house has 2 minisplit compressors mounted on the exterior wall of the house. This is nice to keep leaves and debris out, but when the compressors and fans are running, I can hear NVH in the living room. They are all direct-coupled to the wall. To address, I replaced the rock-hard molded bushings that Mitsubishi provided with soft, thick units from McMaster Carr. I also torqued the nuts properly, unlike the ham-fisted installer did. I tethered the tops of the units to the house with stainless safety lanyards, in case of a top-over, if that is even possible. I yanked on them pretty good, and while they move, they are very secure and stable. This mod reduced the NVH in the house to about 1/4 or less than it was and cost about $50. Job 2. Power and Data I previously paid an electrician to add a dedicated 20 amp 12/2 line for future audio. Plans have changed since then, so I re-routed that power to the wall where the Quatros and amps will live. I also installed floor-mounted boxes from Lew Electric, which are really nice US-made parts. I installed a duplex outlet for each speaker/amp, and a third one for the rack which also has 2 Cat6 lines, which I re-purposed and moved from over the fireplace. Couple of notes here. I initially regretted not having the electrician run 10/2 cable. But, in the course of working these and installing these outlets, I was pleased I did not. 12/2 is hard to work with! Especially if like me you insist on wrapping the copper around the screw terminals instead of using the quick terminals. Also, I thought I was slick and fancy with box covers with removable plug caps (they do look nice) but I discovered when I was done that my Furman 20-amp cable cannot fit through the opening in the cover. Lew sells flip-up caps, but they don't look much bigger. Maybe the Vandersteen power cables will fit through, but I am not betting on it. So I will probably have to run without any covers so the cables fit, which is a little bit of a bummer. Maybe I can come up with an alternative. Also. I used Hubbell outlets, which are quite nice I think for $18 apiece. I had one Pangea in stock from my previous system, and it's more or less about the same as the Hubbells. More mods to come, I will keep updating this thread as I go. These are the easier ones. Edited November 13, 2021 by JonM 3 Link to comment Share on other sites More sharing options...
