This is great.....I can drop right down in the middle of this...the tone controls are there for a reason, and if you can maximize your listening experience by a simple turn of a tone control, I suggest, why not? Purists may say not, but as duly pointed out by the two highly respected long players above, there are so many variables that must be considered between the wishes of the engineer and the realities of your listening space, equipment and personal preferences, that IMHO, the question of occasional usage of the controls to remedy a poor presentation by an album becomes invalid. Without available tone controls, the options are limited to changing equipment or components, but then that sound change will apply to all future playings....a definite personal preference choice. The right answer, as noted in a previous post, is please yourself, it is your listening experience that matters. Personally, I only very occasionally use tone controls, and only exactly for the reasons mentioned above. Enjoy the music!
