Doesn't matter. Their current models (the mono and the 2 ch) leave the baby Benchmark in the weeds. It's just a kid's amplifier by comparison.
Back in 2002, nearly 20 years ago, Halcro showed everyone how to design amps with the DM58. Then Candy built the DM88. If you've ever seen, listened, and touched one, you wouldn't even question. Dredge up some technical reviews and weep.
Now we have the Halcro Eclipse mono and stereo. Built by the original engineers and improved. Choose your poison if you think they are a bad option when it comes to true state of the art in amplification. But, be prepared to be eating a truckload of humble pie in the harsh spotlight of hindsight, should you dismiss their superiority.
Sure, they are a truckload of money, but not a lot compared to much other supposed SOTA gear. But, I know what I would be buying.
