DVD-A player - while they still exist


My Denon 2910 is on its last legs. It no longer plays SACDs or CDs. I fear it won't play DVD-As much longer. I also fear DVD-A players will disappear from the market. I only know of two still around - the Ayre universal and the Oppo 95. Even Meridian seems to have given up on the format.
I only have a few DVD-As, but they're important to me. I don't want to lose the ability to listen to them.
So I'm wondering if I should buy a good player while I still can. Maybe one of the last Meridians, used? Or a new Oppo? I'd have to keep it under $4,000, preferably way under $4,000, unless it was also the best CD player I had ever heard.
Any suggestions?

Yes I would have a backup of course.
But I still think the hard drive will crash sooner if I was accessing it for music. Here's why: I sue the computer for at most two hours in a given day. The rest of the time it's asleep. If I were to add a couple hours use to it, but listening to it through the stereo, haven't I just halved its lifespan? And if I crash my hard drive, I've nnot only wrecked a component in my sound system, in this set up, but I've not got a computer offline, which is always a huge pain.
Why do you say the hard drive is being constantly accessed?
You must have aleady thought through this. Let me know your ideas.
Thanks.
Michael--why not get one of the releatively inexpensive Universal Players, such as the NAD that I mentioned, or the Oppos (range $400-1200), that play DVD-A?
Why not just put the music files on a Nas drive, or a USB drive and access the music files from there.. no wear and tear on the computer...
