Then there were 2

OK I have 3 amps on my short list but one is not available due to supply chain issues.They are ARC Ref75SE, Rogue Stereo 100, (and not available is Quicksilver Mono KT/120)
Question sin it is down to the Rogue and ARC are the comparable (or as they say a coin flip?) or is one considerably better than the other.
I like the fact that the ARC use KT150 and the bias is accessible on front panel.
