No, there's certainly no problem with the bass of DVD-A. This urban legend could only be due to the lack of understanding of bass management & the poor manner in which many (most) manufacturers implement it.
As to whether it's "worth it"- that's a little tougher. I absolutely love DVD-A (and to a lesser degree, SACD). The best discs sound so much better than any LP or CD that it's almost stupid. But- you're right, there's very little material. $25 for a 30 year old
Yes or
Foreiger disc? Yeah, that's gonna sell players...
I do have Beck's "Sea Change," the two newest Steeley Dan discs, Porcupine Tree's "In Absentia" & The Flaming Lips "Yoshimi Battles the Pink Robots" and I think they're absolutely SOTA.
It's hard to say whether it's worth it or not. There's a lot of material out there if you like classical, but again it's mostly vintage stuff reissued. Some of the MC remixes are tremendous, but many are dreadful. Is the format growing or dying? It's hard to say- there's a trickle of new releases, but every week there's an announcement of another delayed or cancelled release. My local Best Buy has scaled back their SACD section by over 50% and reduced their DVD-A section slightly. That can't be a good sign.
I guess my best advice would be too look over the inventory at
Music Direct- they have nearly every disc in print in DVD-A & SACD. If you like what you see then you might want to take the plunge. You'll have to assume based on current evidence that an explosion of titles is unlikely given the maturity of the format, so base you decision on what's already out there.
FYI, I listen to DVD-A almost every day, and to me it's worth it just for the great discs I already have. YMMV.
