I hope you got the front handles for your 28's! They aren't just for show.
When I move my 28's - which is rarely - I ask a friend to come over. We each take a side and can get it without straining our backs. Those handles front and back are super appreciated. 85-90 pounds each and it's almost always a weird angle of approach, so two people are better than one.
Don't worry about vacuuming under them, hah!
Regarding size, I came from a Bryston 4bsst-2 and it took a while to get used to these two silver beasts.
Last Fall I put them on 3" platforms with cones. Poor things had spent several years atop scrap plywood, oh the horror of it. Natural maple dyed black, not stained, and 6 layers of satin lacquer topping. The added height really stuck out, took a while to get used to it.
Once the music starts you'll forget about it anyway.
I did notice a slight tonality change for the better atop the maple platforms. Just before the New Year I replaced all the 3/4" fiber board on my Solid Steel shelves with 2" maple and noticed a similar improvement. All from Timbernation. Great people to deal with. 10year customer.
Happy New Year, enjoy your new thrill rides, welcome to Club 28!
