Looks like PCM96 kHz would be enoughHere's the average power spectrum of the sample track:

what's that thing (singularity) at 150 kHz?
Yes, proper 768 khz music. From Sound Liason which does make very high quality recordings. I'm not aware of commercial offerings at this rate before though maybe I just missed a few. Alas it is only 24 bit instead of proper 32 bit recording.
You can download a free sample track which clocks in just under a gigabyte in size. Pleased to see if you've purchased it at a lower rez, they offer to deduct the cost of that from buying again in the higher rez format. Of course they are transcribing the master tapes from their Studer A80 RTR.Carmen Gomes Inc. - RAY!

Here is a quote from a promotional email as I'm on their mailing list.
Ray! in 768kHz The RME company is highly regarded by audio professionals.
Before we started working with Merging, RME was our converter of choice. So when we got offered to test the RME ADI-2 FS, a compact 2-channel AD/DA converter we gladly approved.
The first comparison with our Merging Anubis was immediately positive. Lots of definition, a beautiful soundstage with perfect placement. And after powering it with the Ferrum Hypsos external power supply, a sense of calm and control was added to the experience. This is clearly a serious converter. The RME has a maximum sample rate of 768kHz. To really see what the RME ADI-2 is capable off, we created a 768kHz/24bit file straight from our Studer A80 tape recorder playing the ¼" reel to reel master tape from our latest release.
Listening and A/B comparing with the Studer the result is quite convincing. In our opinion the sound is very close to the analog master tape.
We would like to share the results with you.
Therefore we have made one 768kHz track from the album available for free for a limited time period.
The only favor we ask in return, is that you give us a bit of feedback; Is this a way forward?
Do you also hear an even greater sense of realism compared to the lower formats or are you perfectly happy with the formats you have been using so far?
For anyone who would like to purchase the entire album in 768kHz but has already purchased the album in a lower resolution in the past week, the price difference will be refunded. Send us an email and you will receive a refund within a few days.
Happy New Year and best wishes!

Probably ADI2 Pro FS.How did they get 768 kHz out of an ADI-2 FS? I thought this was a 192 kHz device.
Well at one time it was fashionable for speakers to have super tweeters. You'll need an ultra super tweet for that.Look what I found googling 150khz tone: a blind test!

I think Sound Liason probably has the best or among the best microphones. Everything is top notch except going to tape. I would have thought they record digitally, but I'm not sure of their workflow.It would be nice if these fancy recording companies got serious about their craft and spent more time on mikes, and mike placement, and setting up the musicians for sucess rather than using a silly mix of obsolete tape machines and overkill digital sampling.
Frequency response specs on professional tape machines tend to be more on the conservative side. Almost any good machine can in reality get to at least 20kHz flat providing proper setup. Also, they are surely using a more modern mastering tape than the 3M 202 (which is not made anymore) in the spec sheet for these recordings. Analog tape machines have more of a problem in the low end with higher amounts of gain needed which can increase noise, and head bumps. Ironically, the faster the tape speed, the worse the low frequency response.Here is the spec sheet for the Studer A80... nice machine and I am sure it it more than adequate to make great recordings but 768 Khz sampling when the tape is only good to -2 dB @18 Khz ?... they just lose credibility with me and I do own some of their recordings.

Of course they are transcribing the master tapes from their Studer A80 RTR.
I had a Studer A77 Mk II with 15 ips capability. It had been refurbed just before I got it around 1990. Very similar to the A80 actually. Spec'd at SN of 66 db which I thought odd. My measures of it ( I didn't have as good a way then as now of measuring such) were around the 60 db mark.That was the giveaway for me. 30Hz-18kHz @15IPS and a S/N of ~61dB.
