... regarding the preamplifier gain issue, 35 db is far too much for virtually any audio system to utilize. You’d literally have no range of the volume control i.e. one click above the 8 o’clock V.C. knob and it’d be too loud even in systems with very inefficient speakers.Sorry, but you are completely mistaken. There is no inherent correlation between the position of a volume control and the actual output of a preamplifier. Different volume controls have varying tapers, and it's the taper that establishes the link between the control's position and the output of the preamplifier. You can design a control's taper to set the output anywhere you like along the control's rotation.
