"NEVER" is a strong word so of course my answer is a "soft" never (meaning if it meant my kitten's life or the end of civilization as we know it then I'd give up the can in a heartbeat) -- the Qualia. We'll likely not see its kind again for a very long time. Along with the HE90, it represented a rare balls-out effort to make the best product possible in its day, regardless of price. These kinds of borderline-arrogant efforts don't always succeed in the business world (and in the case of these two cans the efforts arguably didn't), but they sure are fascinating from a historical perspective as well as an aesthetic one. Of course, they sound pretty good too!
