Schiit Yggdrasil A1 versus A2 Upgrade

Anyone have an Yggdrasil A1 that they have owned and then upgraded to the A2 version? I currently have an A1 that I have owned for a couple of months. I bought it from the original owner so I know all its history. Its fully broken and been constantly kept on. Initially I found that leaving the Yggy off between listening sessions simply make it sound horrible. It needs to be at working temperature all the time.
Upon extensive listening to digital sources and comparison to vinyl and RTR the Yggy simply doesnt come close. Lacks dynamics, bass!!!. 3D space, lacks punch and power. It sounds like a compressor is attached to it. It has lots of detail and a rather balanced sound to it but thats about it, I dont see what is so great about it. Its lifeless, has no sparkle, it doesnt come out and grab your senses. its boring.
I sort of feel I am at a point of selling or upgrading. Heard so many good things but now that i have it Im not sure an upgrade will fix all the Schiit that Schiit screwed up on in the first design. Its also annoying paying for upgrades that essentially are design flaws.
I was hoping some of you members had done the upgrade to A2 and had some A1 to A2 experience you would like to share.
