Speakers "Disappearing"

@georgehifi Hi, can you pls advise if the "audiophile" test albums are very helpful in testing a system's capabilities and help with setup?  I came across these two on HDtracks and was wondering if they're worth buying:

The Chesky one I mentioned was the only one I’ve come across that centred on getting imagining and depth right with your speaker positioning.
Let me say right now though if you have all your audio gear on racks in between your speakers, say goodbye to your depth of image.
The best is nothing between the speakers and as back as far as you can, a speaker guru Neville Thiele (rip) told me this, who with his mate Richard Small invented the Thiele and Small T/S speaker parameters , and I’ve never looked back.

Michael Green, welcome to this forum. I have used your products for many years and am enjoying your "RoomTunes" in my current room now.

All things equal, the electronics also make a big difference. Same speakers, music/source, room, cables, and now throw in a good class A SET tube amplifier in the mix and the speakers will just melt in the room. A good tube preamp will also paint a very different picture of the music between and around the speakers.
