@spenav thanks. The idea for the room and the setup has been evolving for a long time, starting before I even had a physical space to build it. Frankly, even though 5.1 Blu-ray soundtracks sounded great pretty much from day one with multichannel DSP correcting for any latent room issues, it took a long time and a lot of work to get two-channel direct stereo to sound great even though the Arcam has a decent amplifier section. It wasn’t until fairly recently that I determined the flatscreen was a big part of the problem. I never listen to two channel music without the screen covered anymore. Now both analog and digital two channel sound much better in direct stereo sourced from my external front ends than two channel digital processed by the Arcam, due in large part to substantial improvements in those sources combined with the screen covering trick.
Good luck with your efforts to get better sound.
