Trying to understand MQA by reading their patents is risky endeavor (Jim Luserf's excellent article, and similar). Meridian should allow expert dissemination of their approach. Either they are onto something or not. Their patent has issued (see below) so they have protection. US Patent 9,548,055 "Doubly compatible lossless audio bandwidth extension" issued January 2017 to Peter Craven of Meridian.

MQA Discussion
Quote:
Hi clpetersen, Thank you for the kind words. And please let me share a few personal comments. First, in my experience I have found that results are very system dependent. Second, in terms of whether DSD is yesterday's news I have to mention my recent extended experience with several DACs: Aqua Formula, NAGRA HD, Playback Designs MPS 5, and the Pacific Microsonics Model 2. The former two were on long term loan and the latter two are my long term references. All listening comparisons were done with the Sound Galleries Monaco 2015 server and the new 3.16.0 version of HQPlayer which upsampled the native file resolution to the maximum that each DAC could handle. Without getting into DAC to DAC comparisons, what I can say is that the performance of each DAC was an order of magnitude better with the new 3.16.0 version (and the highly computationally intensive xtr filter) than the previous baselines. These were jaw-dropping differences in each case. Yet it required only a software change in the SGM/HQPlayer - a zero marginal cost that was on the order of a major component change. And the DSD DACs? Well the two DSD DACs, Playback Designs and NAGRA HD, made me pause and rethink my previous PCM centric perspective. Perhaps a DSD DAC coupled with the powerful and transparent SGM server, and the advanced signal processing HQPlayer filters, could be the future. DSD DACs yesterday's news? Nah. At least not in my music room. Last edited by cmarin; 04-12-2017 at 02:33 AM. |

Hello CMarin -
thank you for the update. I agree, in the digital realm, advanced signal processing can have significant benefits. In fact, I listened to a Lynn Klimax system with your model speakers (Magico Q7 II) demonstrating their room correction software. It was impressive.

FROM AURALIC:
“This pretty much means we at AURALiC are saying no to MQA. We are no longer interested in their technology. We want to keep everything open but they want to keep it closed. We are not in the same boat. I don’t believe the very High End will benefit from MQA as it only degrades sound quality, not improve it.” “We do not use any MQA technology, this is not MQA certificated or MQA licensed. We are up-sampling the file using our algorithm, applying our own in-house developed filter, to optimize sound quality, not just for a particular DAC but all devices.” “There is a MQA pass through function which allows you to output an untouched signal to an MQA-certificated DAC. I suggest you compare our decoding and MQA decoding but only after the final firmware release. The current version is only a test version as we are still optimizing its sound quality, especially the resampling plug-in.” |

James,
You posted sometime ago that Bryston was going to reach out to the MQA folks. Anything you can share as to whether Bryston will come out with MQA-enabled products? Thanks. |

I have finally lost all interest in MQA and will not be seeking any MQA enabled components, or seeking to buy their so-called authenticated music, just like I did with SACD in 2002.
