Welcome to the forum btrbcomposer!
The ACB Doubler, Mack Brass 1150 and Wessex Dolce are in the same relative price range. I own the Wessex Dolce and it is a fine horn for the $1200 I spent a few years ago, it is a little bit more now. I also tried out the ACB Doubler at home recently as part of a traveling try out experiment between ACB and 4 of us here on the Forum. It, too, is a fine horn for the price point. I find these two horns fairly similar in quality and playability. One more similar to a Yamaha, the other more similar to a Besson. The Mack Brass, from all accounts, is also a fairly nice horn, but I have no experience with it, and it is also the cheapest of the three.
The Wessex Sinfonico is hand made and about twice what the Doubler and Dolce cost. From all accounts, this is a very nice horn and a clear notch above the other three mentioned above. If I had $3K, I would be inclined to get the Sinfonico, if I only had half that, either the Dolce or Doubler would be my choice.
All of these horns come from China, so there is sometimes a wait. Wessex usually gets shipments every 3 months or so. Wessex travels to China before each shipment to quality check each horn before accepting them. They probably have the most stringent quality control of the several brands above. The Doubler offers several different finishes and has a satin brass finish which is very striking.
I don't know anything about the TE 2052 (other than the fact the seem to have stolen the number from Besson).
There are a wealth of reviews in the Euph Brands section, just do a search for the instrument you want to check. I have done reviews for both the Wessex and Doubler.
Good luck with your search and choice and again, welcome to our little corner of the universe. You will find it welcoming, friendly, and highly useful.
