I paired a similar tube setup with Fritz speakers, and Fritz remarked to me once that Cayin worked really well with his. You might ask him about a home trial.
@dz13 you are welcome!
Portugal is a great little country, with great weather, mostly with simple and friendly people. All foreigners are very well received and almost everyone speaks English at conversation level. You have the immense coast, beautiful beaches and also the countryside, diverse according to the region. I am in Alentejo, essentially the more important agricultural region, of renowned beauty, although in the summer we get up to 45 degrees hot days, and cold nights, like in the desert,
Then have the north, with a rocky green landscape or the south (Algarve) with all the amazing beaches, so you have very much to choose. I all depends on what are you looking for :)
