In regards to "whimpy" pre amp..... National semi conductor developed a series of lo-noise hi gain LM3xx series of chips that became a workhorse in all kinds of stereo and audio systems.
The chips have hi-gain and 75khz band width so equalization doesnt degrade the performance with .05% distortion.
I bought some on ebay for about 22˘ each think of what a mfg would pay for them.
