Audible Illusions Modulus 3A an upgrade?
I'm using a Tube Audio Design TAD-150 signature series preamp with a Rogue Audio 90 power amp feeding a vintage pair of JBL 4311 speakers. I listen to mostly "classic rock" and blues.
I've been reading about how nice the AI Modulus 3A preamp is. Would it be considered an upgrade over my TAD-150?
Please forgive what might be an "ignorant" question from, but I am pretty much a "newbie" to high end audio.
thank you so much for your ideas.
