Picking a Tube integrated amp


Hey all. Trying to figure out my amp situation and am looking at a few integrated to upgrade to. 

I currently have a McIntosh integrated and want to move to tubes. I have the vivid v1.5speakers and a Clearaudio Concept. Looking at the following:

—Primaluna Dialogue premium or HP.
—Audio Research VSi60
—Octave v40SE

Question...does the AR still hold up? It’s likely it will be a used model, but curious if it’s still competing with the others I listed. Any others to consider?  

Thanks!

Perhaps a bit off topic, but can anyone detail whether there are any real issues with buying a Chinese made amp (Line Magnetic, Cayin, etc.) - which were build for 220v ?  Can you just purchase a 220/110v converter [box] and be done?  Or is it more complicated? And will it always be a little sonically different than a made-for-110v product ? TIA
From all I've read, the Pharaoh is not the most forgiving/"tube-like" of hybrids; I'd be very inclined to drop some NOS Mullards in there to give it every advantage.
gillatgh- Let us all know how you like the Rogue. Tubes are addictive IMO. 
Keithtexas- Good question. From my experience good deals can come from used gear, but good quality customer service is from a reputable dealer. In my case, my dealer assured me he would handle problems with my amp, if they occured. He was good for his word and so was Line Magnetic Audio. They are a small company.
Received the Rogue today, all hooked up ready to go. Initial impression is positive but not conclusive. Gonna let it burn in for next couple of days before some serious listening. I'll post results when I have a better feel/ear for its good and bad points.
One of the best (and worst) addictive habits one can acquire is the new old stock NOS tube search. I like old Sylvania military grade tubes and old RCAs. But there are so many with Telefunken and Mullard as favorites with many tube fans. Have fun!
