Even though I'm not a smoker, I've found that cigarette smoke makes my speakers sound sort of dry & harsh, while cigar smoke makes them sound somewhat coarse, but in an interesting, earthy way. The best smoke, smoke that SERIUOSLY improves both PRAT and Air, is from glowing jasmine-patchouli incense sticks held up by a burned-in shatki-stone holder. The stone needs to have a green-marker stripe on it at 45 degrees to the sticks while the stone itself sits on a large block of unfinished rock-maple that's spiked into the floor. The incense sticks themselves must be of hand-hewn myrtlewood and seasoned for at least three days in the urine of a in-season booroola-marino ewe...though I've heard that yak-urine also works.
