What is the best 2 channel listening chair?

That's a nice piece.....good price also

Stressless by Ekornes.

Aesthetics aside, I've found the Steel Case Leap V2 (version 2. The V1 is no good) is a remarkably comfortable and offers the most adjustable chair I've used. I have purchased them for home office / listening, personal office, etc. I like the cloth better than leather which I found too firm. Add an ottoman of your choice and you'll be pleasantly surprised. Madison Seating offers great prices and service although shipping can be complicated. But, they sell for significantly less than Steel Case dealers. https://www.madisonseating.com/leap-chair-v2-by-steelcase-sale.html If you want to spend a bit less, the Steel Case Think is good but does not offer as many adjustments. 

Stressless are good...but very expensive and not as adjustable. In addition to that, they don't stay put because of that round base, and always need to be adjusted. I know because I had another brand of chair that looked just like a Stressless.

Finally, at least in my 11x13 listening room, the separate footrest was always in the way. Now, if I'm not reclining the chair is just a chair. 

Most commercial listening rooms employ a padded backless bench. There are no sound reflections around the listener's ears and it has the added effect of being uncomfortable enough that the listener will not linger there.
