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.

Ive owned serveral Audible illusions preamps all the way to the latest m3a. I was a jbl nut also. Spend your money else ware. The stepped attens on those are a joke, the sound is great, You know a great speaker is the L150 my son. That will be a big diffrence. Keep your preamp. Use the money elseware. L150's. Its too easy to upgrade electronics people should do more speakers.
Thanks for the great ideas. I'm thinking I'd best stand pat for now and just relax and enjoy the tunes!
you have a great system. those jbl's are better suited for classic rock than pretty much anything out there. they(along with their sibling the 4312)are still considered classics. they were used to master more music during the our lifetime then all other monitors combined. the 4312 is still sold in japan and retails for nearly 2000 u.s. dollars. even at that price its a bargain.
Wow, I couldn't disagree more. No imaging, shrieking highs, colored mids and sloppy bass. They do thump and play loud which made them a popular rock speaker. Whatever floats your boat.
Thanks Jay! The I love my 4311's and would be hard pressed to part with them. The may not be "high end," but, as you mention, for what I listen to, they're best for me.

I met Richard Vandersteen (of Vandersteen speaker fame) at an audio store where he was demonstrating his newest line, and got to talking with him about my favorite albums and artists. It was he who suggested the 4311's to me in the first place because of their use in mastering all those great classic rock recordings.
