I have heard some say it's gone for more than $100 or even $200. But who knows from what time this was noticed, as the market for demand changes, or if it's even true.
It's a great CD, and people have to hear it in lossless to understand how strong it is (this goes for any good orchestral production), but I'm not sure a rather obscure orchestral 90s arrange album is in that high of demand these days when ppl can find MP3s of the thing quite easily. Also, since then the market has been flooded with similar orchestral releases from many other companies; so this album struggles to find its identity. Another problem is that the cd is pretty short for a symphonic album.
What can't hurt it though is the fact that it is still the only official orchestral arrange album from Konami for Castlevania. You won't hear "Vampire Killer" or "Wicked Child" this way anywhere else. There's a bit of that 90s new age flavor peppered over the production, so its decidedly a different sound from most other CV albums.
SOMEONE out there would be willing to buy it decently high, and you literally have next to no competition: like I said I've never seen a sale of it. But it could take awhile to find a buyer. My advice is to just keep reposting it, lowering it a little each time.
