Ayre QB9 Dac . Upgrade to the new QB20. Vs competition In the $4-5k range or less


Hello I am looking to find out regarding the New Ayre upgrade for All QB9 dacs to the New QB20 Dac 
i see 1 review and  reviews many times are in part swayed with $$.
how good is this new upgrade ,and how would the QB20  and Schitt Yggsdrusil stack up 
and compare with each other . For these are my 2 options , please do chime in ,Thanks much.

sorry for a minor threadjack, but i have a quick question...

the qb9 is USB input only, yes?  i have a codex, really like it... but i don't use usb as input (have streamer not computer doing the streaming)... would like to hear ayre's evolution of their DAC's but i can't use the qb9 (upgraded or not) if it is USB digital input only...  

thx
