Hi Erik,
Coming back to the title of the thread, I have listened to PCM vs MQA files from the 2L website via the mqa-capable Meridian 808v6 player in my home system.
I found that the 808v6 renders the PCM version beautifully, and there is an incremental improvement with the MQA version. Having said that, I couldn’t compare DSD vs PCM or MQA versions of the same files as the Meridian does not do DSD.
But comparing PCM vs DSD via my non-MQA Esoteric N-05 dac, I preferred PCM. Needless to say, I can’t listen to MQA via the Esoteric.
That said, comparing the PCM versions through the Meridian 808v6 and Esoteric N-05, I preferred the Esoteric. The Meridian foreshortens soundstage depth, bringing me to rows 1-3 while the Esoteric places me at rows 7-9 which I find much more pleasant and natural. Meridian’s Explorer 2 does the same thing according to a Stereophile report while RH of TAS observes the same thing in his review of the 808v6. Also, the highs are airier via the Esoteric.
The only way to compare DSD vs PCM vs MQA, would be via Meridian’ s new Ultradac which does all 3. Now, that’s progress. I have not brought home the Ultradac simply because of its prohibitive cost.
Best regards.
Jon.
