@bluorion I had an MA252 for about a month and sold it. It is okay but that is it. If I were to go Hybrid I would look at Pathos or Vincent or Canotr ($$) .
The Raven Blackhawk will be a good jumping off point for getting into tubes. It will drive your Tektons fine and if you decide to go another direction (upgrade) you have a product that will sell well in the Gently Loved market. Also I think Raven has a trade up program if you want to stay in the Raven Family...
@millercarbon is right the Blackhawk is a good mid to entry level integrated that you could live with for a while. Beats SS unless it is AVA M225's.
