There are lots of preamp s I have Custom built preamps far better then commercial where 70% of your hard earned money goes into the unit s parts . Did you know less then 25% on average hoes
Into any commercial product the rest ovrrhead,and 40-50%
Dealer markup. I owned a store and know about nodding,
And quality. Used you can find good equipment
But first you want very good quality coupling capacitors installed
Very important under 10 years old , any older capacitors of thst era start drying out on lesser brands, if remote control most use alps volume which you loose a lot of inner detail .look for resistor based , or processor . There are a ton of variables. Being in audio since the mid 70s ,I have a college education .
