Don't let tubes put you off. I'm running Pathos Classic One MkII tube hybrid integrated (can be stereo or bridged mono) and they are incredible. Best move in amplification I have ever undertaken. Opened a whole new world of enjoyment! I absolutely adore the sound of the Pathos inegrateds in bridged mode! No issues with heat, adjusting, etc. Just plug and play pure sonic pleasure! Make sure you get a remote if important to you! Also, if expandability/upgrade is important make sure the amp can be set to bridged/mono mode. Then you can later ad second one and biamp. Another incredible leap in performance!
It is truly an economical way to achieve wonderful sound. To give an idea how lush the sound is, I also have a Naim Nait 5i integrated. No slouch of an integrated, and about the same price as the Pathos when I bought it. But when I put it into the main system I could only take it for about an hour. Had to remove it and put the Classic One's back in. I didn't expect the Naim to sound better than the tube hybrids, and it didn't. There is a richness (imho) in a good tube hybrid that an all ss integrated has trouble achieving, unless perhaps moving significantly higher in cost.
