if you wanna go that route.. if the average consumer understood how pointless are these super high sinad numbers outside some very niche applications, and that they'd be much happier with an amp with lower sinad but significantly more features, better QC, better warranty and customer support... or just slightly lower sinad for less money... then the LA90 would sell even less
funny how this "consumer education" works, right?
Not sure where all these accusations are coming from, nor do I understand the inflammatory tone. I own many Topping products -- 3 DAC's, a headphone amp, and the LA90. I haven't had a problem with any of them. I've also read online that Topping honors their warranties, but you have to ship to China.
I agree that too much wattage and too much SINAD are both unnecessary for the average consumer. But wake up. We're living in a world of "too much." We have more quality and quantity than we "need" for just about anything, if you live in a first world country.
The reason engineering products - of *any* kind - demand a premium price is very rarely because the consumer needs that level of quality, but because of a kind of respect for the engineering achievement.
And hate all you want, but the LA90 breaks new engineering ground in at least one dimension. There's no arguing with the numbers. If you want to call it useless, that's up to you. I find that having 5x+ the wattage that you'll ever need for your use case is equally "useless" and much less impressive.
