There are several issues lyin' there.
First, is the source credited to anyone? We're on 10 years of quad to "something else" (dts cd, dd dvd, dvd-a, multichannel flac...) and for the vast majority of the early years output, which was 99% dts cd, you may have a hard time to understand who did a specific conversion. Sure, Tab did *the* lot, but it wasn't alone: the dts scene was ruled by Tab but many followed, with different degrees of success. Other than Tab... probably a dozen of converters. many times discs were without any cover or specific info of who did that, so you may just guess who did that, especially when checking out the Tab list and that specific title wasn't there.
The real problem was in the success factor. Some were happy to record to wav from a misaligned Q8 deck, at the wrong speed or with a flutter that will make sick even the most trained sailor, and likely with a very worn head - hope that *at least* the head was clean.
I'm not exaggerating: i still have something done that way lying on a hard drive. Pretty unlistenable... unless you do some hard work.
I did it twice on the same fileset, a CCR Gold q8 transfer, first to dts, years later for a dvda, and pushed it well over the edges to have a decent sound. Neil can confirm how lousy was this source and how stunning was the result compared to the source.
Of course when i got the real q8 in my hands the results were a lot different but... heck, it tooks me 9 years to put my hands on that Q8! Meanwhile, at least i could groove with the proud mary even if it wasn't so good as the others.
Said that, if someone can do a better job from my work i'm more than willing to listen. I did what i could with the tools that i had at the time. Things can improve, both on the "tool" side and the "expericence" side, as i've seen by myself the second time i did the CCR workout. The source file were the same, some tools were new and i had 4 years more of experience to clean out things while keeping the sound. After all, if someone can improve what someone else did first, we all gain something better.
Currently i haven't seen someone doing that, other than the few RQR releases. I'm missing something?
