I disagree. I don't think that MQA has any bearing whatsoever on Meridian's future success.
Meridian still has (very) high end consumer products (is it making any profit from these?), but the core business it's targeting is clearly the custom install market. Will the likely purchasers of these custom installations care about MQA? I doubt that 99% of them will have heard of it.
You may well be right.
However, don't forget that two of Meridian's latest products, the Ultra DAC and the 857 are not intended for the install market. The DAC is certainly at the high end but the amp is in the middle of the market. This represents Meridian's return to the analogue market by cleverly adapting technologies and products to extend its reach. This is a very welcome development.
And as Meridian are the inventors of MQA, and likely to be the most advanced in its implementation, it seems perverse to throw away that commanding position by not fully exploiting it.
