It is impossible to duplicate what sound engineers heard in the studio. They make adjustment after everything is recorded to take into consideration of public media playback. What you do want is a system that can reproduce the detail and dynamic range very well. The piano, cymbals and kick drum are a good indicators of the fidelity of the system. Depending on the source, the sound retrieve feature has a role in improving the overall SQ of a source. The two features that I do not use a lot are pure direct and direct since most rooms are not perfect and these mode will not get me a better sound. Some people feel MCACC mask some of the sound but, this is volume dependent and a simple turn of the dial is all that is needed IMHO.
When people talk about warm sound they are talking about coloration by the avr or distortion. I own tube and SS gear and they sound very similar at low and moderate volumes. The warmer sound from the tube gear is more noticeable at higher volume. The thing I like about tube gear is the vacuum tubes glowing, not that is pretty cool, lol.
