Actually, as the Data Systems Architect, Program Manager, and Acquisition Manager, yes I was an expert in extreme scale databases when I retired. Six years later, I am probably an antique. That technology moves faster than SMSL can introduce DACs.
If you think Gold Note answered your question, you have zero understanding about how an amplifier works no matter how many times you insult me. I do hope they are nice amplifiers, but I will never know.
"Doubles the power when reducing impedance" So what. Any good amp can.
"Switching, but not class D". OK, they did not say what it is though.
"Exactly like class A" Nope. Not at all.
"More efficient" Yea, so is class A/B, G, H and D.
Again, I hope they are very nice. I hope they have some innovation to add, but their marketing BS you quoted does not give any hint and their published specs would not make it on the shelf at Best Buy with the boom-boxes.
I just ordered a Schiit Vidar. They have excellent customer service and their web site plainly explains the audition return policy. Their specifications include the test parameters. For half the price.
I intentionally live in the boondocks, if you call 1.2 million people in the area the boondocks. Lots of wildlife in the woods behind me. My camera has snapped coyote, fox, bear, deer, possum, racoon, otter, skunk, owl, hawks, herons, and way too many copperheads. No obnoxious street lights, no kids drag racing up the street at night. Spread out enough I can crank up my subs without bothering anyone. But only half an hour away from world class medical and a Super Walmart. I vacationed to DC/Va/Pa recently and hit a few remaining high end stores up there. Kind of like Home Depot, they all have the same generic stuff. I'll stay down in the Piedmont, thank you. Amazon makes it to my door in a day.
