If its not full bandwidth how can it be natural?? Real sounds are full bandwidth. Real sounds are natural. So there's the disconnect.
I'm not saying you can't get a lot of enjoyment out of a system that isn't full bandwidth. But let's not be fooling ourselves- its not natural by any stretch. I've restored a variety of older radios and tuners that I use about the house and really enjoy playing them but I don't think for a minute they produce anything natural.
So perhaps you could explain how something that fails to produce the entire signal is 'natural'? I really do want to know.
Could you make a recording of a human voice anyway you want and play it back on any system you want and make it sound natural? you’re in charge of all decisions and the voice does not go to the bottom octave. Can you make that voice sound natural from a recording?
