Ayre CX7e: Is the final mp upgrade worth the money

I finally landed an Ayre CX7e CD player, and it sounds great. I have read a review in Stereophile that the "mp" upgrade is not only worth it, but brings the sound closer to analog and to another level of performance.

Would like to hear from a few Ayre owners who own or owned a CX-7e player, and had the final "mp" upgrade done. Was there a noticeable or marked improvement in the sound quality to warrant the expense?? Thank you!!!
Pt consulting, do you know if they are using the same Pioneer transport on the CX7e as they used on the C5xe?
Another positive vote for the"MP" update/upgrade. Go for it! Sounds wonderful and is worth having Ayre check your transport to boot. Keep me posted & Happy Listening!= JA
I know the new transport is different from the original - different manufacturers. The original develops an intermittent problem with age where it just won't read some disks.
Thanks to all who have responded so far. PtC, thanks for the heads up about the transport.

After talking to MiKe at Ayre, I anticipated the cost to be about $250 plus shipping to Boulder Co. I am a little concerned about the install of a newer transport. However, I am not doing streaming, downloading, or ripping CD, just old fashion CD playback in the hope that it will sound excellent despite the half-ass recording of and re-mastering of many CD's
