The BasX A-100 offers all the essential features that make a great audio component, like a heavy duty power supply, great sounding high-current short signal path Class A/B amplifiers, industry standard unbalanced audio inputs, and full-sized five-way binding post speaker terminals. The BasX A-100 delivers a solid 50 watts per channel into 8 Ohms and 80 Watts per channel into 4 Ohms; plenty to drive most speakers to satisfying listening levels.

It has LOTs of power, like you said, but also LOTS of noise relative to good $100-$150 headphone amps and a high likelihood of channel imbalance. The recent Audioscience Review test
[audiosciencereview.com] shows distortion at .012%, Noise at 78dB below signal, and about .5dB L/R channel difference at 5W (likely higher at headphone volumes).
By comparison the $99 Schiit Heresy has .0007% distortion, Noise 103dB below signal, no channel imbalance...and PLENTY of power for 99.5% of all headphones. Plus, the Heresy has an external gain switch, so you do not have to open the chassis anytime you want to switch between high/low sensitivity headphones.

Completely different product. Different amp class.
Most of this is greek to me

Thoughts?
Their "trigger" mode will cause distortion on every time it's triggered, so you have to keep it on. I thought there was something wrong with my unit, but they RMA'd a unit with the same problems.

Sounds more like a criticism of the $800 amp than praise for the emotive. What where your results with the schiit amp?

I use the A-100 as my desktop amp, driving a pair of PSB Alpha B speakers and feeding a 10" sub (using speaker level connections). Sounds excellent.
Keep in mind, the power switch is in the back. I've relocated it to the front for convenience.
I get that is how it is supposed to work, but spending more doesn't always mean you "get" more. What where you results with the schiit amp?
Hey, so they've updated their entry line (BasX) of power amps. BasX A2 is what the closest thing to the A-100. It's $449 but the specs are quite a bit improved. It's still maintains the architecture of the original, a high current, short signal path class A/B output stage. Power output is one of the differences that stands out, originalpoliz, l00, : 50W per channel into 8 ohms and 80W per channel into 4 Ohms.the new design :160W per channel into 8 ohms and 250W per channel into 4 Ohms

Also looks like their new stereo amp will be $450! https://emotiva.com/collections/n...-amplifier
Why and what did you get then? I was thinking to get a desktop amp and speaker for vinyl and cd. I know nowadays it's much easier with Bluetooth and wifi/AirPlay, but still want a set at home. Thanks.
