haven't heard the 450's and although i own a pair of JC-1s
which have given me much satisfaction,i also believe as others have stated that you should probably lean towards your preference for tube amps.
the JC-1s seem to favor balanced SS preamps and your Supratek may or may not give you the ideal synergy.
also it is my belief that the amp should be chosen in accordance with your speakers strengths,weaknesses and requirements.in this case both options appear as overkill.
