Picking a Tube integrated amp

I thought Prima Luna was made in Germany....perhaps not...

You might look at Quicksilver Audio's integrated amp. If 20 watts per channel is enough. Their amps sound really nice. They have been around for more than 30 years, and are made in the U.S. And the price is very reasonable

I’m intrigued by the Octave.  What do those who’ve recommended it like about it?  I’m thinking about the 110. Oh and by the way, I ended up selling the Vivid’s and bought the Focal Kanta No2 for speakers. My room was too big for the Vivid’s.  The Kanta is amazing. 

Not sure what the buzz is surrounding the KT 150. The question I would ask is how do they sound? Not how much power they put out.

What don't you like about your McIntosh? Why do you want to move to tubes?  The Vivid 1.5's have been characterized as clean-sounding speakers delivering masses of detail.  If you are looking to inject a little warmth by introducing tubes then the Octave may not be what you are looking for, as it has often been characterized as having a more up-front sound that is vivid.  Could be a little bright depending on your room and phono cartridge. In any case, would help to know what you are looking for when switching to a tube amp.
