Dartzeel or Tenor for Marten Coltrane speakers???

All,

I've recently bought pair Marten Coltrane speakers and the next proces will be to optimise my amps.

I currently use the Levinson 33H, Nr 32 combo but am not sure if that is the best combo to go with my Marten speakers.

The two amp that came to mind are the Dartzeel combo or Tenor (not sure which pre-amp to take than).

Anyone to advise me on a great amp and pre amp?

Thanks for your help.
