Picking a Tube integrated amp

I have a Raven Reflection MK2 Integrated tube amp that powers Sonus Faber Amati Tradition Homage speakers.  Outstanding sound, beautiful pieces to display.  You should look up Raven Audio and call Dave the owner.  You did not indicate what your budget level was.  Raven have a couple of integrated options.  He also uses a lot of rare tubes in his amps.  Plenty of power! 

Be careful if you buy a used VTL.....  they don't treat you like a "real" customer if you need support.

"Kalali:

Prima Luna is made by Cayin in China (Cayin goes by Spark in China).

Cayin is owned entirely by the Chinese government so all profits will go to them.  Prima Luna is only made in factories owned by the Chinese government in partnership with Prima Luna. 

If this kind of thing bothers you, then it is something to consider.  If not, just a "fun fact".

You should also consider (as mentioned above) Cayin and Line Magnetic. Both are Chinese brands, Cayin being a government owned company and LM a private one. 
Both Cayin and LM are the makers of several respected western brands, like Primaluna and others. 
I own one amplifier from Cayin (MT45 MkII - push-pull) and one from Line Magnetic (LM219ia - SET). Both are superb in terms of sound, design and built quality. And much cheaper than the equivalent western brands. 
Up to you. Go have a listen if you can. 

AndySF:

Cayin, Primaluna and LM do not bother me.

However, I do avoid food/pet food, cookware/dishware, vitamins, personal care products, clothing and pretty much anything made of plastic/including car parts from China. 

I listened to an "updated" Cayin PP integrated amplifier a long time ago and thought it was pretty good.

Other than upgraded caps it had a triode switch and a pot/knob that somehow seemed to adjust the damping factor.

Forget who did the mods, but it wasn't Upscale.
