Many people have measured with an sound level meter the peaks at the listener position during concerts and rehearsals. The highest peaks are about 105 db(A) at the listener position (not on the stage!). Very many Hifi systems can manage that. Some, with bigger loudspeakers, can mange that also without distortion.
I bet that during the loud tutti of a big orchestra you wouldn't be able to hear what several instruments are playing. Actually depending on the recording on many hifi systems you hear clearer certain instruments than at live performances.
I agree with warmer and more natural but detailed not often. What is heard much more in detail is the projection of the instruments in the hall. The acoustic of the concert hall is on the recording something that has not much to do then the one at the listener position during the concert. There are some systems that can reproduce well and in good details the characteristics of the hall recorded on the media but this will never be the same as the one on live performances. Is this so important? Anyway for those who are used to go to different halls can relativate this aspect.
Well especially big systems do fill the space with sound. I must say this point is for me very important and everyone who visit me noticed this and was impressed I heard though several very big hifi systems which are able to to that.
Having a sweet point or not has not much to do with "filling the whole space wit sound". I just wonder why is it so important not having a sweet point: anyway even in a concert hall you sit in a place and don't move. Or do you walk around, turning your head around when they are performing?
With certain acoustical changes in your listening room it is possible to enlarge the sweet point a bit. Most of it depends though on the characteristics of the loudspeakers.
Definitively not: it goes to about 32 Hz. Timpany goes down to about 70 Hz. There are many big systems where you feel the lower frequencies in your body much more than in a concert hall. But also speakers like Tannoy do that job, for me not in a natural way.
You will never be able to get the original. But there is no original: if you move 4 seats to the right, to the left behind or in front in the concert hall, it will sound anyway different.
Still you can come close to a realistic perception. In any case there should be a bit of compression in classical music: the position of the microphones are much more closer to the instruments than any listener. I hope your ideal is not to hear an orchestra 2-3 meters away form the performers.
I don't have any big issues with recordings, also modern ones. Most of my x thousands of CDs play on my system with great dynamics and enough details. It is certainly a question of what system one has.
Interesting. May I ask amps and speakers you use?
