I have owned the Merlin VSM's in a couple iterations and I have owned the two amps I am going to suggest...but I have not owned them together (amps and speakers) so my suggestions are based on educated guess as opposed to real experience.
The Bel 1001 MkV would likely be a good choice as Bobbie suggests...very good amp.
The Stellovox PW-1's would as well IMO....perhaps even better than the Bel.
I have used the Stellovox with many speakers that were only supposed to work well with tube amps and the Stellavox has been excellent in each case.
This of course does not assure that they will sound good with the Merlin, but if I were a betting man....
I have heard that the Golmund SRM 125 mono's are at least as good as the Stellovox but I have not heard them or owned them and they are rare and more expensive than the Stellovox.
