What problems? These are single stream discs in the main, with one stereo mix in LPCM & 2 lossless codec forms as well for some bizarre reason (sponsored deal somewhere, maybe, with Dolby & DTS)
Have you had problems with any of them? If not, then I am sorry but I fail to understand the question or even the reason for it.
It's generally better to buy the record than to look for a problem before you even try!
The problem is that there seems to be no problem.
I was curious if the question would bring out any real gripes and version wars like we see sometimes with SACD v DVD-A. (I suppose I was playing Devils Advocate)
Apart from the lack of video and lack of "extras" all seems to be well apart from the odd report of certain disks not playing on the 105 (I think).
IMO the lack of video is not an issue, I listen to music on pure Audio settings so any video is off anyway, if available it might be watched once but that would be about it. Also there was no video on LPs or Tapes.
The lack of "extras" also does not worry me, it seems like a call to "King Size" it at McDonald's.
I would think there is more chance of getting Hi-Rez to the masses via this medium than any other which has to be a good thing.
As for the lack of 5.1 hopefully that will come in time but the uptake has to be there for a medium with the capacity to carry it.
I own three HFPA disks (Sea Change, Breakfast In America and Nevermind) have one on the way GYBR (plus a copy for LizardKing) plus the DSOTM Blu-Ray and have no issues with any of them.
Owning the SACD of a OOP rarity such as LoveBox has a kind of magic to it but I could have bought six or seven HFPA disks for what I paid so a format that appeals to the masses and encourages the labels to release more has got to be good.
Yes they could be seen to be gouging more cash out of our pockets by re-releasing old albums but the real market is the great unwashed. We, erm.... audiophiles, are only a minority they certainly haven't been released purely for us.
