Stockfish Records is a very highly regarded German record label that produces new recordings of acoustic music. They release their products on CDs, SACDs and vinyl LPs. A recent comment regarding the quality of their recording brought me to their website where I discovered another new format announcement. The format known as DMM-CD\/SACD was announced last summer.<\/p>\n

I’ve already talked about DMM or Direct Metal Mastering (read Direct-to-Disc<\/a> but this new format takes the freshly cut copper metal part immediately back to the digital domain and results in a CD\/SACD hybrid disc. Clever idea…maybe.<\/p>\n

Here’s the introductory blurb from their website:<\/p>\n

“More and more music lovers are discovering the unique sound of a vinyl record. We have thought about whether it is possible just to make the sound creation factors of a vinyl record audible. A pressed record however has many artefacts arising from the vinyl pressing i.e. distortion, rumble, groove noise, vertical and lateral aberrations, clicks, etc. and other artefacts that are detrimental to a good sound. Having said that, music lovers have already become accustomed to these disadvantages.”<\/p>\n

I find it interesting that Stockfish, a provider of 180 gram high quality vinyl LPs, includes a discussion of all of the bad attributes of vinyl pressings in their statement. And they’re right about the shortcomings of vinyl. The sound of vinyl may be desired but the hassle and compromises required to produce one make it too difficult for me.<\/p>\n

The DMM-CD\/SACD uses a state-of-the-art cutting lathe (a Neumann VMS-82) running at 45 rpm to cut a fresh blank copper substrate. The RIAA equalization curve is required, of course, and the usual sonic modifications are applied as the signal is sent to the cutting head. Things like summing low frequencies to mono and hyping the high frequencies are typical modifications. Only a small portion of the entire disc surface is cut to optimize the geometry of the pick-up arm…minimizing angular distortions during playback.<\/p>\n

Then they “playback” the copper master from the cutting lathe with an EMT\u2019s Broadcast TONDOSE TSD-15 cartridge into a EMT JPA66 valve pre-amplifier to apply the RIAA reverse curve and then digitize to 1-bit DSD 64 using a Meitner EMM Labs adc 8 MK IV analog to digital converter.<\/p>\n

“The DSD signal is then recorded at a sampling rate of 2.8224 MHz on to our SADiE DSD8 mastering system. Later, on the finished Hybrid-SACD, you will find this true 1-bit DSD layer and also a generated CD format at 16-bit\/44,1kHz.”<\/p>\n

In essence, Stockfish Records is giving you the best possible vinyl LP fidelity as a digital file…and they’re calling it a new format. Well, it;s not really a new format, but it is an interesting idea…if you’re a fan of vinyl.<\/p>\n

It reminds me of the Volkswagon automobile company. The VW bug was originally designed and manufactured in Germany during WWII. The novel ideal behind the VW beetle was to perfect it year after year until the ultimate automobile emerged. While other auto makers were busy doing expensive aethetic changes to their models, VW was actually refining the bug. In the end, the VW beetle is the perfect 1940s car. Rather than adopt new materials, technology and engineering processes, they perfected a design that is decades out of date.<\/p>\n

Isn’t that what Stockfish has decided to do? They’re offering the “fidelity” of a vinyl LP in a digital container. While I haven’t tried it,there are various vinylizer applications or plug ins that you can use and presto…out pops a euphonious version of the original with the low frequencies folded to mono, lots of high end and limited dynamic range.<\/p>\n

Their decision to capture the output in DSD 64 is a questionable decision (I would use 96 kHz\/24-bit PCM) AND then to extract a downconverted 44.1 kHz\/16-bit PCM file for the CD from the DSD file, argh! A well-down CD from the outset would save them a lot of time, expense and trouble.<\/p>\n

You can get a copy of this hybrid SACD\/CD for only $33.<\/p>\n","protected":false},"excerpt":{"rendered":"
