Best U.S. made integrated tube amp under $2500?

Because we have a minimum wage here in the US, and we don't beat our children for not reaching their production quota's, it is quite difficult to produce quality gear at an affordable price. With that in mind, DIY kits can save some labor costs. I do know that Dynaco clones are on the market from various manufacturers; I am not sure but I think that there is a reissue of the Dyna SCA 35 which is a tubed integrated amp.

Hmmm. I would look into the Manley Stingray and the Rogue Cronus. I assume 40-50 tube watts is more than enough to drive the Dulcets. What I would buy for the price, and better than all of them in my opinion would be a Lightspeed Attenuator and Music Reference RM10MKII for $2,500 total, new. Don't think any of the other three options would be as good - but not an integrated and while the RM10 is handmade in California, the Lightspeed comes from Australia, but handmade by the owner so certainly not the product of "cheap" labor. The RM10s have enough power for my Merlin VSMs (89db, 8 ohm) so its's 35 watts might be enough to drive the Dulcets if they are not to be played to loud, in a smallish room like yours; I assume if you own Dulcets, you are not a headbanger....that would be a significant step forward IMHO. I think you would be more than impressed with what the Lighspeed/Music Reference could do for your wonderful speakers - the combo is cheap, but SOTA for a 35 watt amp.
