Experience with Zesto Andros Allasso SUT?

@three_easy_payments   I found your thread about the Zestro Andros Allosso.  I am very interested in getting one for my system and would like to know if you did acquired one and by now what your evaluation is of its sound quality and how it added to your system. 

Thank you very much. 

@three_easy_payments   Thank you for the prompt reply.  That's a very good answer.  I have several cartridges and will likely add another one or two.  The Allasso provides plenty of load and gain matching options that should satisfy my needs.  How did you find the sound quality of the Allasso with the variety of cartridges you mentioned above?  If not going with a specific SUT/cartridge combination would you still be running with the Allasso?  Thank you very much for taking the time to reply to my questions.
