I read the little dot spec as throwing 5wpc. That is close to enough, if the amp can swing current/voltage rapidly and in large buckets (which some tubes amps seem to be able to do).
Never heard the Allnic with a HE6, but folks that have tell it does a fine job with 5wpc.
The WA5 with 8wpc does a great job with the HE6. Folks that have compared the WA5 with a thumping huge wattage solid state amp tell me that it gets 99% of the performance - just drops a sliver of the bass response.
You mean even the WA5 with 8WPC it gets just 99 of performance and dtops slightly of the bass response?
