As an ex-professional drummer, I always knew that placing several bronze cymbals around the drumkit made the drums sound better - warmer and more ambient. With this in mind, I purchased a 12" or 13" Opera Gong from Gongs Unlimited for about $60, complete with stand and tried placing it on the table in front of my listening seat, midway between the speakers. I'm really past the point of conducting numerous A/B comparisions, but I tried listening to the music with the gong covered with a blanket and without. My experience was that the gong gave the music a more open and harmonically rich presentation. At least that's what it seemed. Could I tell in a blind A/B? Who knows and who cares. I just felt it was worth a try and, at worst, I'll be left with a dinner bell. BTW, it happens to be a very nice gong for $60 with the stand.
