Speak for yourself.
This amplifier seems to lay bare some of the the hollowness of SINAD. I can't easily remember the last time I gave more than cursory thought to distortion levels when buying an audio product, because it is now so rarely an issue. Think the last time was about 7 or 8 years ago when I considered a DSD DAC, tried a product and decided not to bother. Anyway, I listen mostly to vinyl these days.
The reality is that 88% of the votes are for FINE or GREAT without having heard this thing, it would likely be a massive fail with many people's speakers and heaven knows what happens when it's asked to do some heavy lifting in the bass department. Transient speed? Dynamics? Let's wait and see.
Call me cynical, but Topping send out pre-release units to ASR and
www.l7audiolab.com/f/topping-la90/, both of whom give glowing opinions and top panther/wolf awards on the day the product is released. Is that more than coincidence? The concerns here are shared over there as well (power, price, impedance, build).
