Why would anyone use HD Tracks for Downloads?

I really enjoy hi-res computer audio music files I've downloaded from Liaison in Europe. These files were recorded direct to digital and I download them as 24/96 FLAC or WAV files. There is an obvious improvement in dynamics, soundstaging, noise floor and detail over CD that make it worth the small increase in $$.
My understanding is that all, or at least the vast majority, of downloads offered by HD Tracks are nothing more than existing older standard resolution analog masters transferred to PCM or DSD format digital files. Standard resolution recordings transferred to a hi-resolution format cannot produce hi-res music files. An analogy is transferring a steak served on a small plate to a larger plate; the steak will still taste the same and there is no improvement in taste. Music originally recorded on a multi-track analog reel-to-reel recorder will have limited dynamic range, a higher noise floor, a limited frequency response and less detail than the same music recorded directly to digital.

I know there currently is a lack of major artists taking advantage of hi-res, direct to digital recording of their music. Most of the truly hi-res music seems to be coming from lesser known artists. I've found that i Trax in California and the Liaison Music Shop in Europe are 2 good sources of true hi-res recordings.

So, my question is to those that have downloaded supposed hi-res music files from HDTracks: Are you disappointed by the sound quality of your purchases from HDTracks? I would think you would be, since I believe you're listening to standard resolution files that should sound no better than CDs or records you may already own of the same material.

I'm very leery of buying HDTracks downloads not only because of the above, but also because they fail to list the source of their downloads; there's no mention of whether they're simply transfers of standard resolution masters or are recorded direct to digital and actually are hi-res.

I'm interested in readers' thoughts on avoiding standard resolution files advertised as hi-res.

Thanks,
