Recommendations for Integrated Preamp Migration to Separates?

You'll be able to get much better sound from a good integrated like a Raven Blackhawk or Reflection than just about any combination of separates you can put together for the same total cost. https://www.ravenaudio.com/product/blackhawk-mk3/ But while I will do everything in my power to talk you out of throwing money away on separates, I wouldn't for a minute want to discourage you from upgrading to the Herron VTPH2A phono stage. That's a true no-brainer. http://www.herronaudio.com/vtph2specs.html

Thanks for the feedback. The Raven products are gorgeous indeed; however, I should clarify my post.  The Audible Illusions Modulus 3A is a preamp with an integrated MM phono; my AIM3a is interfaced curently into my power amp already; so not looking to replace the power amplifier right now.

I am trying to determine which part of the Modulus preamp would be a better upgrade path by separating the phono and line stages by either 1) purchasing a new phono preamp and use the AIM3a just for its' line stage OR 2) keep the AI preamp to use as just the phono stage and into a new preamp (ex LTA)? I have read that many early Modulus owners bought the preamp for the phono.

Read many excellent reviews regarding the Herron VTPH2A.  However, I wonder whether the AI Modulus 3a if used then as just a line stage would be up to task for all that the Herron could provide?
