192/24 versus 96/24 sound wise
HDtracks is offering now Files with different Bit rates (resolution). Did someone do a comparison between 96/24 and 192/24 files on a DS? Is it worth to spend 9-10$ more?

1. KDS/1/d, LP12, KK/1/d, Akurate 242MkII new Stand aktive with AV5125(d) (Bass), A3200(d) (Mid), A4200(d) (Treble), Akurate 226, all silver IC, QNAP TS-239 II Pro +, AV5103
2. Classic Movie(d) with 3 Zones: 2x Roomamp, 1x Roomamp2, Komponent

I'm also curious, especially in case of Rolling Stones. I wonder if I will hear enough difference between 176/24 and 88/24 (e.g. Beggars Banquet). HD tracks should offer 30-second clips for comparsion. Otherwise, you even don't know what you are buying (and I'm not sure if you can trust 100% when paying for ultra HD tracks while they might be just upsampling from standard resolution).

marker, I believe you mean the sampling rate. '24' in "96/24" is the resolution (bit rate, aka bit depth). In general with high-res audio, the bit depth is more important than the sampling rate. 96 khz is usually more than enough and a jump to 192 khz usually does not yield a noticeable difference. 192 khz recordings take up a lot of memory as well.

As for HDTracks, it is offering hi-res music at lower sampling rates than 192 khz which in theory is okay. In general I have found the recordings superior to their corresponding redbook versions. Most recently I was very pleased with the Beethoven 5th and 7th by Kleiber.

Sample rates of 88.2 khz do get me suspicious sometimes since it is exactly twice that of a redbook CD's sampling rate.

88.2 is also half of 176.4 that is the sampling frequency of the Reference Recording HRx disc (more info here http://www.referencerecordings.com/HRx3.asp). It's also the frequency of choice when the digital master derive from a DSD if I remember correctly.

There are a handful of free sample tracks on http://www.2L.no in several formats, including 192 and 96 FLAC.

I found the 192 was more detailed and instruments were easier to follow, more instruments could also clearly be perceived. Albeit this was with orchestra pieces where the benefits are perhaps more marked. I always buy 192 when it is available.

RE: 192/24 versus 96/24 sound wise
I listed today to some new downloads from HD inkl. Diana krall, jane monheit (96) and Louise Rogers (192). I have to say that the 196 from Louise Rogers are the best sounding tracks I've heard till now and I have a lot of high res ones. Soundstage, channel separation,... The only however is that I couldn't compaire the same tracks with different resolution.

Actually you can ...... as I did recently for a meeting of the Shanghai Audiophile Society. With the dbpoweramp software and using as a "master" the HR file, is possible to downsample it to the resolution you want and be sure that the only difference will be in the bit number/sampling frequency and not to difference in the mastering process.

192/24 versus 96/24 samples
WRT HiDef files, here is a site where they have offered some prof. produced files from the same recording sessions with the same mastering at different sample/bit rates for comparison:

If you are going to change sample rates look into dithering.
