Audio Research or Macintosh?


Could I have comments/opinions on the two tube/hybrid amps on my short list, namely the Audio Research VSi75 and the Mcintosh 252.

Thanks.

Sorry, that is obviously the other way around, from Ayre phono preamp to Settanta.
Great choice, I’m sure you will totally enjoy!

I have audio research equipment and used upscale audio For my last set of replacement tubes. Very satisfied. 
Also have not had any problems with my audio research gear.
It's nice to hear that you have experienced reliability biketony, lots of naysayers out there criticising the longevity of AR products.
Also had good experience with Upscale Audio for replacement tubes in my AR preamp.  Using AR components throughout my system.
Early ARC tube amps had little protection and gave them a reputation that is still around but totally unfounded today. I think you made a nice choice with the VSi75.
