Marantz vs. Emotiva

dbw1, I'm just a "fly-on-a-wall" with this thread because while I have no familiarity with either component you mention herein, I do have two pieces of Emotiva gear I'm happy with, so I'm concerned with the lack of servicing you have experienced. Have you asked for a replacement? FWIW I have a ERC-3 CD player and CMX-2 power conditioner.

dbw1, irrespective of your intention by virtue of this thread to understand if the Marantz would be a step backward in terms of sound quality, if you have purchased an Emotiva product and are not completely satisfied because of a manufacturers defect while the product is still under warranty, you should be entitled to a refund or replacement. My recommendation is to call Emotiva and ask for Lonnie Vaughn. Explain your situation and at least make an attempt to be fairly compensated.  

@dbw1 I have some presumably favorable news for you. Emotiva just announced - not on their website but via email to certain subscribers/customers - today their "fall trade in" deals. They are offering $150 for your UMC-1 even if it is out-of-warranty and/or not working. Caveat is (a) you must be original owner (b) must purchase something of equal or greater value and (c) offer expires 11/15/16.
