What Integrated Amp do You use

I think we're in a golden age for integrated amps. A lot of great ones already mentioned. I'm in love with my Boulder 866, which also has an incredible digital add-on that will allow you to sell your DAC. I was a separates guy for years, but the simplicity and all-around excellence of the Boulder put an end to that. It's just astonishing.

I own a Gryphon Diablo 300 because of my power hungry Thiel CS 3.7s speakers.Perfect match.

The last 14 months a Douk Audio 15wpc.Class A amp based on the Sugden A21 but I am getting ready to get either the Sugden A21SE or the Pathos InPol Remix MkII to drive my Harbeth M30.1's & ProAc Tablette Anniversaries...

Raven Blackhawk. Finally.

Decware SE34I.5.  Granted you need some highly efficient speakers with 6 watts/channel.  Love what an EL-34 tube can do regardless.  Something about what has been done with a pentode tube ran as a triode is magical.  Hands down, the most musical set up I have ever listened to.
