That is an excellent point, and you can hear that effect all the time in Hollywood scoring. Somebody writes utter, nearly infantile claptrap and the orchestrators and generally excellent studio orchestras make it sound like music. Play the same thing on a piano and everyone would laugh it out of the room. You can fill in the blanks for whatever current composer you wish to accuse. There are lots of them.
I also agree on Svetlanov very strongly. My example is the Borodin B Minor symphony. I heard this played by another big shot conductor and major orchestra (non Russian) and it sounded pathetic and limpwristed. Then I heard this performed by Svetlanov and the USSR and it was like night and day. Extremely powerful and definitely an example of one's heart being in it.
