Copland also used to make Valve hybrid amps CSA-28 I think was the last model number,well worth a look if you can track one down second hand,even better is the CTA 402,lovely sound,excels in the Midrange,vocals,and goes beautifully with the Cal DACs,low maintenace,built like a tank,beautiful amp.

 

  The AA puccini doesn't compare,I found it:SLEEP:in comparison.
