Audible Illusions modulus 3A, what would be the next level of up grade?

I had been running an Audible Illusions MA3 for 10 years when I sent it back for some updates and repairs, I took advantage of AIs very liberal trade in policy and took possesion of the new pre 16 months later. Both pres had the John Curl phone boards and needless to say I loved them both dearly, with that said I did not want to go into my retirement with a piece of gear I could not count on the builder to repair and get back to me within a reasonable amount of time. I went through 9 very good preamps and an equal amount of phone preamp to settle on a Lamm LL2.1 Deluxe and an Allnic H1500se ll phono. I was really surprised at how much cash it took to better the Modulas 3B, other pres that I used and really liked were the 1st Sound Presence Deluxe lll.
