As regards Trifield, I would also find that it is beneficial on about 40%-50% of the music that I listen to. It's very dependent on the material and sometimes even different Tracks on the same Album can benefit (or not) from Trifield

As regards Upsampling (and Resolution Enhancement) I always find this to be beneficial and not just because it is smoother

And to return to the Thread topic: While I've enjoyed the accessibility and ease of use of our Server fed "Thru house" music system for the past 3+ years now, I would always return to my 800 for CD Music replay and critical listening on our main system. There are subtle differences that I can quite easily hear and for me, these differences outweigh the accessibility and other advantages of Server based music

I think Meridian can bring something to Player end of future systems, I'm not so convinced on what they can bring to the Server or Back End
