I'm very disappointed in the usage of DVD-Audio logo on this box set, when in fact I discovered that the discs are authored as DVD-Video spec.
I'm not against DVD-Video discs for surround sound audio. I have all of the Jethro Tull box sets, for example, and how they do it is how I recommended Cherry Red & Esoteric do it.
I have the 2021 Jethro Tull A La Mode box set next to me right now, and it has the DVD-Video logo on the back, to accurately represent the three DVDs contained within. DVD ONE is also very transparently described on the back as well:
DVD ONE (Audio Only)
Contains Steven Wilson's 2020 remix of the album, and 5 associated tracks (3 in surround), in DTS and Dolby AC3 5.1 surround and stereo 96/24 LPCM and flat transfer of the original LP master in 96/24 LPCM.
That's very clear and unambigious. Please use that as your example, and do the same, Cherry Red & Esoteric!
Beyond that complaint, I'm also disappointed in the sound quality of the discs. They sound very bright to me, to the point that I could not listen to them more than 10-15 minutes. I quickly put some other surround discs into my system, worried that something had gone wrong with my setup, but fortunately (or unfortunately, depending on perspective) the brightness and harshness seemed isolated to just this box set's discs.
Since I have never heard this music before buying this box set (these deluxe editions are great opportunities to hear something from the past I've never heard before), my hypothesis then turned to "well, maybe this album was just really poorly recorded on shoddy equipment?"
I quickly ordered an original pressing of the vinyl LP of this album, and happily it sounds so much better than the music of this box set. So I know this album was recording well enough, and was mastered/cut well (by Wally Traugott, in the case of the original LP).
That leaves me to conclude that this box set is not mixed or mastered to my liking, compared to other surround sound titles in my collection (of which I have hundreds).
Finally, I did hear the rumbling of the discs in my Oppo 105D player that others are complaining about on this thread.
Last time I remember experiencing that disc warping problem that is suspected, was with the Richard & Linda Thompson CD box set from a few years ago. That box set used similar cutout slots to hold the discs, and as best everyone could piece together through investigation, there was some sort of issue after the discs were put into the slots in which weight(?) pressed discs against the unevenness created by the slots, thus warping them. I was among those who stacked the discs for a photo, which clearly showed how warped they all were. In the case of Richard & Linda Thompson box set, an entire new run of discs were manufactured, they were placed in much more secure "clamshell" cases, then mailed out to everyone who requested replacements.
