The room is large - diffusers help scatter the sound giving it a sense of even spaciousness - the sound is also less colored - first reflections points towards center of wall are absorbed by the three 6” roxul absorbers - the overall sound in this space is large more enveloping with less localization - micro dynamics and the jump factor are also enhanced - room acoustics in the space have evolved over many years with as many errors.
Some absolutely stunning dedicated 2ch set ups and a lot of beautiful H.T. set ups doubling as 2ch. I love the different efforts on room set up.
I also have an H.T. doubling as a 2ch rig. A pair of PolkAudio RTiA9's powered by an Emotiva XPA-2. With an Oppo 103 running through an Onkyo 807 for CD play back. IC's and cables are nothing fancy, just the basic.
