You’re correct, Bob Stuart and the Meridian team have always worked on sound engineering principles, which is why he/they have been pioneers in the field of digital reproduction and encoding for decades. Just an observation, but it seems contradictory that you trust Meridian to do the right thing with DSP volume control (which, by the way, is a hybrid digital/analogue control to avoid the worst of both technologies) and don’t trust their claims that reducing jitter to the absolute minimum possible is beneficial to sound quality.

I'm quite sure reducing or eliminating jitter is beneficial to the sound quality. I have two opinions though:

1. Jitter can't cause squish bass.
2. HDMI doesn't introduce jitter.

I also suspect that dissing HDMI is a marketing ploy to hide the fact that Meridian doesn't have enough money (or market, or willpower) to build a blu-ray card for the 861 and license all the technology required (ironically).

I'm at the far end of the used market, and the "hand me down" pipeline used to be 861vX cards -> 861vX-1 cards -> 568.2mm -> 561. There was always something coming down the pipe, but it seems like the current head of the "used pipeline" for home theater is a Trinnov, not a Meridian.

I couldn't find the thread, too old, but I did read about measurements for jitter of many mainstream BD players, it shows HDMI carry much higher jitter than coax.
