Belcanto Power Amplifiers

Dgaylin would you say that the difference in quality justify the substantial difference in price between the S300 (or M300) and the Ref 1000.
I am ATM hesitating between the Nuforce 9 SE v2 and the Belcanto Ref 1000 or the M300 as an alternative). The rest of m system is a RA Opus 21 and a pair of Gallo ref3 vII.
I probably will onlybe able to test these amps in different places and with ancillaries I am not familiar with, that is the reason why I am asking

Many thanks Dgaylin,
I will be audioning the Ref 1000 and the S3000 tomorrow (5 hours of train round trip!), although unfortunately again with CDP and speakers I have never heard. Life for audiophiles is not so easy here in the UK.
I will then try the new Nuforce SE v2 and then I'll make my choice. Will keep posted
