For a quick good time, blankets...

Good point. :-)

Both have their drawbacks. Sheep are disorganized and require herding dogs (German Shepherds, Collies, Rottweiler, etc.) while stewardess are unionized but they do tend to favor the smaller dogs. Much to ponder....

When using sheep I've found it best to stay clear of the Merino, English Leicester, Shetland and Awassi breed as they tend to seriously over damp the sound, while the Lleyn, Charollais, Wiltshire, Shropshire and Hampshire tend offer the best compromise in absorption. 

My only caveat is that on rainy days it gets a bit gamey and tends to ruin the whole affair.

I used to drape an old army wool blanket over my TV flat screen since it sits between my speakers and it does make an improvement but I've gotten so lazy that I stopped doing it. The trick is to not overdo it. Case in point: I replaced an overstuffed sofa with some lounge chairs and the sound improved noticeably from the mids on down to the bass. I would never have sold my old speakers had I replaced that sofa first. You never know until you try.

All the best,
