The amps you listed use different power tubes and sound quite different. If I were looking for a tube power amp for this system it would be a mac MC225. Sounds sweeter than the MC240 IMO. New Tung Sol 7591A power tubes are relatively inexpensive and sound great.
My next choice would be an EL84 amp. The Shindo Montille is superb but there are other, less expensive options.
