To answer your question, I have started purchasing SACD's since end 2005 / early 2006 when I got my Denon A1. At that time, I had specifically chosen a DVD player with SACD playback. Less than a year later, I added the NAD M5 (2000€ no less) in order to have a specific, dedicated player for SACD's.
From 2006 until today, I have bought more than 300 SACD's, including 288 classical or orchestral (see my library). In this period, I have purchased exactly 2 RBCD's of classical music and one of them was a listening nightmare...
In the last two years, my amount of RBCD (non classical) purchases has dropped to maybe 1/4 of what it was before, and still dropping.
You do the math...
Punyversal, DG, EMI and Naxos have gone to my blacklist, for having dropped SACD and in general not being interested in producing quality products, only dragging our money.
As a matter of fact, I didn't know your label before starting to buy SACD's.
There is currently one RBCD reference on my maybe-maybe-not list, that is your Sibelius integral series. If you had released them on SACD, even stereo only (that hurts for a multichannel supporter like me to say that but it's the truth), even non-hybrid, I would have bought them immediately, without any hesitation.
Considering the many people who visit this site, even without logging in or posting on the forum, (I did that for more than a year before registering on this site), and the currently more than 20 millon SACD players in circulation I would be surprised you could'nt find the 600 more customers you need to cover your additional costs.
As conclusion, if I need to buy every new BIS SACD title to keep you issuing them, I will. At the very least this would make me discover music I might have (probably wrongfully) overlooked...
... And by the way, I'm also interested in SACD reissues of your back catalogue, as it has been suggested earlier in this thread, even if they are stereo only (Oops I said it again).
Keep up the good work, thanks to you music listenig remains what it should always be : a very important pleasure !
