Phono preamp suggestions; can I improve upon my Aesthetix Rhea Sig ?

Congratulations on your new upgrades,

That is a tough call, because only you will be able to determine if something will be better in your system. Yes, typically, a more costly, or the next higher device in a lineup should sound better, but; that is not always true, depending on the system. 

If it were me, I would wait until you have the VPI HW-40 and Crimson setup and played for a while in order to make an informed decision to determine if something can be improved. You will not know which way to upgrade unless you listen first. However, many have taken a leap of faith, to include myself, to purchase what we felt would be an upgrade. You win some, you lose some. If you already like the Aesthetix sound, then it might be the next logical step to upgrade to an Aesthetix IO Signature or Eclipse. Of course, the XP-27 is also a nice choice. Take your time and enjoy the system for a while in order to inform your decision. Have fun listening to your new setup. 

Skinzy,  Nice table you got there , maybe try add step up tranny to use with MM .

im believer for that set up and cost cheaper too depends what brand .

Bobs devices have SUT that integrated with VPI mount so no add wires.

Enjoy spinning 👍

Definitely will do a wait and listen approach with my current phono pre which I've owned for the last 15 years.  It's a tough question I know, but was hoping someone out there has heard the mentioned equipment and could comment. Recently upgrade my Classe power amps from their last series to the current Delta Monos.  While there was an improvement in SQ it was not as much as you may think. Thanks for comments and Happy Holidays!

Congrats on the HW40. I'd love to upgrade my 10 year old Classic with one.

You could get one of these. HW thought it was one of "the best" he's heard. Personally, I'd just enjoy your already fine setup.
