Edd,

Meridian announced that they would stop further further development of Sooloos in March of 2019, just a little over a year ago.
I like many people here on this forum certainly did not expect new features, i.e. "development", but I certainly expected a company that makes and markets a "luxury" product would not abandon their customers that not too long ago purchased MC200, MD600 and C15's, at well above average expense for a audio product. BMW, Jaeger, Apple and many manufactures of "Hi End" audio products would never treat their customers this way.

I'm very sad to say that this is the sort of thing a company whose principle owner is a Private Equity Firm would do. Their investors always come first, never the other stakeholders.
This is not speculation on my part, I have too much personal experience in these matters than I would like to think about.
