"I think it's delusional to try and fit an orchestra or anything like it into a small sitting room."This is where a nearfield setup, where the soundstage is totally decoupled from the room, is the only way to attain such scenario.... I did this sort of thing back in college to great effect..... Although it was not exactly a system that performed well outside the listening "sweet spot".
"And when you include the voice I have no doubt in my own mind that the ideal is a single ended amplifier with no feedback - could be tube or solid state such as SIT amps. But as Paul Joppa says, not easy to put this into practice without sensitive speakers."
Although there are a select few push-pull amps that might do justice with 90 dB efficient speakers, I think going high-efficiency, roughly 96 dB minimum, just opens up so many more options for amplification. It is otherwise so difficult to get the dynamics of an orchestra right, due to the fact you can only get so much out of an AC mains outlet. (You can get a lot of power out of that outlet, but at the expense of "dynamic linearity".) I've rarely heard 100 WPC driving 90 dB efficient speakers with "dynamic linearity" like I've heard 8 single-ended WPC driving 100 dB efficient speakers.
I don't think dynamics and tone are mutually exclusive. In fact, if the tone is lost, it's probably due to the dynamics perceived as "exaggerated" relative to the real thing. For the higher distortion during dynamic swells/peaks will make them seem "louder" than they should be. (Or in other words, if the music "blasts" during loud passages, the dynamics are not quite there, in regard to linearity.) IMO, this is the most common failing in home sound reproduction, and the most frustrating part of home sound reproduction to get right.

Todd, your comments regarding tone and dynamic linearity are consistent with my experiences also, though I had not really thought about it.I agree that dynamics and tone are not mutually exclusive; however, accurate tone at live levels in a domestic environment might be. Well, it is at least challenging, expensive... and undesirable in my case. I don't want a system that sounds balanced at live levels then lifeless and lean at levels I normally listen.
My preferences are for ease, musical flow, nuance, convincing tone and vitality... up to a volume level I might listen to a couple of times a year but, but not live levels. This is achievable in a domestic environment using simple systems comprising lowish power SET amps and well-designed efficient speakers.
Thanks for the contribution.

From what I've heard (and reproduced live music, quite often I go to opera and symphonic concerts), I do not think dynamics and tone are mutually exclusive. In my opinion the aim of music reproduction is the most faithful approximation of live music in all audio parameters. Last time I heard my reference Prokofiev LP Decca SXL-6620-2 through expensive tube amp + expensive speakers, dynamics were much worse than via my several times cheaper apparatus, as seemed to me that I listen to other LP, music that does not have the dynamics bores me.
Very good site about reproduction of Music are: http://www.high-endaudio.com/ .
I will sometimes inspire by them, I am grateful to the creator for it.
