When I said serious, I meant in large quantity with large sales volume. While there may be some small companies still pressing vinyl for the niche market, it is insignificant in terms of the overall market and in terms of the market for vinyl that once existed.

As for convenience versus quality, I don't think that holds up. Cassette tapes are far more convenient than vinyl. You can play them in your car, while you are traveling, or just about anywhere. They are far more durable and less prone to damage too. Yet cassettes even with the advantage of Dolby never replaced vinyl records. Vinyl was king until CDs came along. And it didn't happen over night. CDs used to cost nearly $20 each when vinyl was $3 to $10 and the cheapest CD players were $1000 and up. It was the adoption by the market that drove the prices of the players and the discs down. Vinyl was doomed even before you could record your own cds but if there were any lingering doubts, that cinched it. Small wonder then that at about age 22 vinyl is viewed by most cd buyers the way 78s were viewed by LP buyers when LPs were about 22 years on the market. That would have been about 1972. At that time, 78s as anything more than a curiousity were considered a joke.

The endless debate over which sounds better cds or vinyl will go on as always just like all the other debates such as tubes versus transistors, class A versus class B, moving coil versus moving magnet etc. You won't settle anything here.
