Post Subject: Optimal Sample Rate.Posted by Romy the Cat on: 7/15/2016

The most interning in Larvy writing was the article about Optimal Sample Rate. Dan Lavry begin to advance this subject in his post at various audio boards from I think 2008 and then in 2012 he convert it into his “papers”

In my view it is very intelligent and considering from whom it is coming is the most credible position. Still, Larvy as any other industry participant I am sure protects his serf. At the time he begin to advocate his position Larvy did only 2X converters and was losing competition to 4X makers. So, he introduced a public idea of inferior sound with excessive rate. The funny part is that Lavry might be very much correct in in the subject but I do not know how to detach his position with him defending that his company never moved to 4X world with top of the line products.

I am very much NOT in position to debate with Larvy. I kind of agree with his and I feel that 2X with no post-recording DSP of any kind (seldom seen) is all that we need. However, I have my own negative experience with my agreement with Lavry. A few years back I had my custom Stelovox with ½ inch master tape at 15 in/s. The quality was very nice and I decided to digitize it. I used Lavry AD and Pacific AD at 88kHz. I was not able to get the identical quality to the quality I was getting from the tape. Then I switched the Pacific to 175 kHz and it was significantly better. I do not know why it was but it was. So, even I agree with Larvy regarding his Optimal Sample Rate position but I also feel that supporters of 4x have a merit.
