It seems that interesting things happen only when you are away from keyboard and not when you are refreshing the browser every 10 secs to check if there are any news.

No problems updating my Meridian Prime on my Mac (actually it's a hackintosh). Didn't have a PSU to test upgrading with that connected. The 4th LED lights up now when playing MQA files in Audirvana.

Yes, they do sound different (probably better) but need more apples-to-apples testing. Not that I will lose my sleep on it. I like music but I won't pretend that I could ever replace an orchestra with just a high-end system in my house, no matter how many thousands I will spend on it. But, me being practical, I will need to consider if MQA is worth investing (and extra spending) on buying new albums and subscriptions from now on. Might even repurchase a few favourite ones but I am not going to overdo it.
