Affordable US Made Tube Pre/Power or Integrated Options


I'm considering switching to tube amplification from solid state. I'm fine with separate pre/power or an integrated. I'll be driving Enzo XL's in a smallish room (17x14) and listening levels are almost always <90db so 30-40 watts should be more than enough. My budget is fairly modest, $2-3k all in. I don't need phono or more than 3 inputs but I would like remote for volume at minimum. Quality build and sound is a priority as is ease of support/repairs if needed. The one unique requirement is that my preference would be for US made if at all possible. Obviously, this limits the options quite a bit but I'd like to see if I can make it work. If not, I'm willing to look at other options.

Here's what I've found so far

Preamps:
Mapletree Line 2CRM, $800 (not US but close)
LTA MZ2- $1595

Power Amps:
Tubes4hifi ST70-35w, $1300
Audio by Van Alstine Ultravalve-35w?, $1599
Quicksilver Mid Mono-40w each, $1995/pair

Integrated:
Rogue Cronus- 100w, $2395
Any others?

I'm open to any other options you may know of. Also, if there's any insight or positive experiences with matching pre/power amp please share. I'm new to tubes so I have a lot to learn.

I have the MicroZOTL MZ2 with the Pass Labs XA25. Might also look at one of the first watts. 
There is a used Cary CADSEI 300 listed on audiogon right now. I'm using one of these 15 watt SET integrated amps to drive Wilson Sasha 2's, and it's wonderful. 3 inputs and a volume only remote. I sold on a more expensive tube preamp and ss amp combo because I loved the SET midrange, particularly on vocals. And personally I don't feel that I sacrificed anything in the bass reproduction.
Check out the Aric Audio site. I own one of his preamps, the Special.
Strongly considering one of his amps.
Should add that Aric is easy to talk to and will answere any questions you have. Also does some mods on his gear at buyers request.  
As for having enough power, I use my Decware with Zu Omen speakers and Reference 3a Decapo’s which are about the same sensitivity as your Enzos and have had no problem with lack of power.
