Audio Mirror Preamplifier

No experience with the preamp but had Vlad's 45-Watt SET power amps for many years. Outstanding product from one of the best in the audio biz. Vlad stands out as a true gem of a person. 

Thank you Vlad @audiomirror for providing accurate guidance and a solution for people with subwoofers!

I'm having a preamp made for me and the designer is keeping the preamp out for the sub separate, load-wise, from the one going to the amp.
