Need recommendations to replace ARC VT100 MkII


Looking to get an amp that is a bit easier to maintain. Also possibly looking to downsize/simplify:
I am considering two different approaches.
1: Sell both the VT100 MkII and my preamp (ARC SP3c) and replace with an integrated tube amp; choices would be
A. ARC VSi60. (Used), or
B. Primaluna dialog premium integrated
2: Keep the preamp and get a new power amp; choices would be
A. First Watt F6
B. Liberty Audio B2B-100
C. Primaluna dialog premium power amp

My speakers are Acoustic Zen Adagio.
Any thoughts or recommendations would be appreciated. Thanks

Mabonn-

which cables/cords are you using? This is an important facet, which, most people over-look. Happy Listening?
Jafant, my cables and interconnects are Analysis Plus. I don't recall exactly which model. Thanks, Matt
Thanks for all your responses. Music Reference sounds interesting. I had not considered it before. I think Ayre may be out of my price range.
What is your range? I've seen the Ayre AX7e for around 1700 shipped (used). That's an integrated and the sound has beaten any integrated I've head it up against in stores etc...
My range is the value of my VT100 plus maybe $1k. Looks like Ayre is in my price range. I will put it on my list. Thanks, Matt
