I recently upgraded my home theatre setup to a modest Denon receiver with KEF surround speakers (and a 4K UD 65"LG TV). This has made me really go back to the studio albums that have been released in 4.0 and 5.1 and I am enjoying them a lot.
It's like the old days when I first discovered Floyd and heard the albums again and again.
I listen to Meddle a lot and a little bit of AHM. The ones I listen to the most are DSotM (in 4.0 and 5.1), WYWH (in 4.0 and 5.1) and Amused to Death.
There is something so delightful in being surrounded by the music. I enjoy AMLoR and TDB a lot as well.
The setup really makes me want Animals 5.1 more now!!
