Attached are several clips for vinyl rips, each in (24/48) and (16/44.1) -- I have many more but 7 I filled up my attachment space.

I used Izotope's SRC and MBit+ algorithms to do the conversion, I converted sample rate first and then bit rate.

The rips were done using Thorens Turntable, Lyra Delos cartride, Parasound phono pre, Burl B2 ADC, Lynx AES16 card, Pure Vinyl software.

If anyone has better conversion technology than Izotope I would be interested to hear those samples for my own comparison, as a practical matter I would like to have the best possible bit reduced versions in my library in addition to my 24 bit versions.

If anyone is interested in specific notes on what I'm hearing as the differences in my playback system then let me know.

The sources are:

Dire Straits "Romeo And Juliet"
Prefab Sprout "Faron Young"
Yes "Roundabout"
The National "Bloodbuzz Ohio"
Cat Stevens "Father And Son"
Roxy Music "Running Wild"
John Lennon "Mind Games"

Thanks for checking these out.

OK, I have listened to Gretschguy's vinyl clips and done a cursory ABX test with Foobar.

I was unable to hear any difference between the 24 and 16 bit versions. The playback was via an M-Audio AP2496 soundcard and modest Sennheiser HD435 headphones. I will acknowledge that the playback chain is perhaps not adequate, but I am not in a position to perform proper ABX tests on my main system (Slim Devices Transporter into ATC SCM100A speakers).

Notwithstanding my failure to distinguish 24 and 16 bit versions (which frankly does not surprise me), I do want to say that these are very nice vinyl rips. I have three of the tracks on CD and prepared the same 30s clips from those in order to compare. I also measured the RMS-to-peak ratio for the CD and vinyl rips:

1. Yes/Roundabout. My CD is an original (pre-remastered) British pressing. It has a bit more weight, whereas GG's vinyl rip has more sparkle and sounds more "airy". Perhaps the impression of "weight" on the CD is simply due to the lack of top end. RMS-peak ratios: CD=16.5dB, vinyl=17.1dB.

2. Prefab Sprout/Faron. My CD is an original (pre-remastered) US pressing (where the album is called "Two Wheels Good" instead of "Steve McQueen"). There is very little difference between this and GG's vinyl rip. The vinyl rip seems to have slightly better defined bass, but only on careful listening. RMS-peak ratios: CD=17.0dB, vinyl=16.7dB.

3. Dire Straits/Romeo and Juliet. My CD is a the first British remastered version. (I suspect there have probably been more remasters since then). The CD clearly has more dynamic range compression than GG's vinyl rip. Apart from the compression, the balance and detail seems very similar. RMS-peak ratios: CD=15.9dB, vinyl=19.0dB.

It interesting to note that there is precious little difference in RMS-peak ratios between the CD and vinyl for pre-remastered CDs, whereas there is a marked difference in the case of the remastered Dire Straits CD. Which pretty much confirms what a lot of us think about remastered CDs.
