Elizabeth, with you listening preferences I would have thought you’d have preferred German. Or maybe Italian.
I have a large leather arm chair with ottoman. I'd say that for me comfort is the number one priority. No matter what a chair means to the acoustic equation if it isn't pleasant to sit in then its useless.
It has a high back, but I am tall. I can sit with my head fully above the back or slumped down so that the back is higher than my head. There is no sonic difference whatsoever.
