Albert has his monitor on rollers & actually removes it from the listenng room altogether for serious 2 channel performance, then rolls it back into place for video. Realize that's not what you wanted to hear but there it is; the blanket method is better than nothing though.
Why not just try it with / without blanket/ vs. completely removed, & find out what happens?
