Audio Research versus McIntosh tube amps: anyone experience or compare both?


As stated in the title of this thread, considering both brands.  I'm looking for a new or near new tube amp to run my Joseph Audio Pulsar's.  Have been using a Pass XA25, which sounds a little lean with this speaker.  Looking for a touch of tube warmth and bloom, but still good detail.

Considering a new McIntosh 275 MkVI or possibly a preowned ARC Reference 75SE.  New ARC costs more than I want to spend ($6K range or less).  Preamp is ARC Ref 2 MKII BTW.

Would appreciate any insight for those who have experienced both.  Thanks!

I haven't listened to ARC amplifiers. I prevously used McIntosh MC275 MK VI and it lacked details and bass. It was weak. If you want dynamic, you won't have it. If you simply want tube warmth, it may work. Good luck!

@ghdprentice  hit the nail on the head. Currently I'm using a REF75SE and absolutely love it. ARC just gets everything right top to bottom. Preamp is Ref6.  

@bobbydd - I’m with Mazian’s comment above. As you mentioned warmth, I recommend the Conrad Johnson Classic 120. That amp uses EL34 tubes and brings a wonderful warmth to the music. I alternate it with an Audio Hungary power amp. The preamp is a Linear Tube Audio Microzotl, which has a tube tone, wonderful soundstage and imaging, with some solid state detail. 
 

The above components, at least for me, have delivered what I was looking for - which it sounds like what you are also looking for - tube warmth with solid state details. Highly recommended combinations.
