Dynamics, both micro and macro, are truly an important and major characteristic of music reproduction, live, and through an audio rig. I am not speaking of rock concert loud ( which can be distorted to the ears ).......As the op says, to be able to go from soft and quiet, to loud, shows more of the passion of the work, by the composer, conveyed through the conductor and the orchestra. Without it, realism is lost.....This has been my continued experience for over 50 years, and without deviating from the purpose of this thread, my tweaked and modified Lascalas, allows these characteristics to shine through, with any and all amplifiers. Captivating, for sure...and with all types of music. It is wonderful that the op experienced this, and a welcome to the Audiogon community, to share in this excitement. Bravo ! I am yet to hear an audio system, that captures what the op ( as well as myself and others ) has experienced, as the recordings themselves are a major limiting factor. Enjoy, and my best....always, MrD.
