I just received an Audio-Technica AT-HA2 Headphone Amp from Audio Cubes. I didn't realize that the voltage runs at 100 V instead of 110 V (US Standard). Has anyone had any experience running a 100 V amp (or any other electrical component) in the US? Will it work? Will it cause an electrical hazzard?

I already plugged mine in. It is up and running.

Have you had any problems with the different voltage?

How does it sound?

My post is here. Been on for like two hours now. No problems.
I think the Audiocubes website states that they don't sell anything that can't be used in the US.
Perhaps the moderators can merge our posts.

the amps got a 7812 voltage regulator in it, so it won't be affected at all unless you feed it above 35volts dc (I think it's 35V, the max input could be lower). But it's not heat sinked so it could die from a lower voltage.

The wall wart could die though, 10-20% more voltage would put it at it's upper limits, if it's low quality.

Does that mean that it should be fine as is?

i'm wondering if the HA-2 amp from audio-technica is good or not?

it looks very slick, and it's damn cheap compared to the ugly looking (IMO of course) air head and super minis. those amps look too plastic and homemade to deserve to be sold 100 bux US.

Hey guys,

can you spend a few words about the sound of the AT amp? I never heard any impressions about it!

Thanks a lot!

I have a lot of electronic gadgets that I bought from Japan. I always use a converter. However, my friends plug theirs right into the wall outlet without issue. I think I'm just paranoid.

Btw, I'm also interested in knowing about what you think of the sound of the AT amp!

You get what you pay for. For a first amp it's okay. But for the price I would go CHA47. It drove my AT A9X well, but the CHA47 brought out more detail. Wanna be cheap and have a nice desk amp? Or you wanna step up to the plate and get something custom made that sounds better. Do a search to read more comments.

I might have posted this somewhere esle, but basically I don't like it. It's noisy, because of a high gain opamp. With low impedence cans, the noise floor is very high and hard to ignore. It's also got a lousy, poorly tracking pot.

Avoid it if possible, but actually there isn't much available commercially at around 5000 yen.
