15% discount? I like half price closeouts
It is a poor headphone amp for 99.5% of headphones. If most people are buying it for that then most are buying the wrong thing.

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.
agreed. Not much of a discount for a discontinued model

Seems to have some distortion until it's warmed up.
Most of this is greek to me

Thoughts?
See above.

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.​

The main selling point of the A-100 is not as an amp to drive speakers......but it has an internal jumper that lets you send the full power of the amp to the headphone jack for hard to drive headphones....

A-100 pairs great with popular headphones that a lot of people use like the Sennheiser HD650/HD6xx and HD600 and some HiFiMan headphones which I have tried with it like HE560. It even drives the HE6se but I wouldn't recommend a $200 amp for headphones of that caliber. I have a higher end $800 headphone amp to compare it to and while not as good, the sound quality differences between the two with the headphones I've noted are fairly subtle and not worthy of a $600 difference in price.

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

No, not a criticism of the $800 amp. The higher you move up the audio chain the more nuanced the sound quality differences become. A-100 gets you 95% there with an HD-650. If you want to chase that extra 5% you can spend more.

Very well.
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?

Nice! Been rocking one of these for years as a headphone amp for my HiFiMan HE-500s! Looks like theyre discontinuing it? I wonder why.

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

I've been using this amp for 8 or 9 years now to drive a set of bookshelf speakers. Usually hooked up to a chrome cast audio or airport express for streaming. Mine is the older model w/o the headphone jack.

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.
