Has anyone ever seen or heard much about this amplifier?

PORTABLE HEADPHONE AMPLIFIER - RA-1 - eBay (item 290195570210 end time Jan-10-08 05:19:20 PST)

I picked one up but haven't had time to listen to it yet.

Two 9 volts is kind of a turn-off for me - makes me think it's got an old-school circuit - and I guess it does:

I think I would rather have a CMoy...

Sometimes I don't understand the combination of hard costs and labor. You can buy the iPod to mini adapter for 12 dollars, which is pretty easy to stamp out and manufacture but the amp, in this case using the name from Grado (which doesn't seem right) sells for just 18 dollars more for a total of 30 dollars (I have seen some of the conditions for this type of work in China and it can range from great to beyond belief). Well some people love the sound of the RA1 so here is an opportunity to buy one (it appears from the parts) for 30 dollars plus a very small shipping cost.

True Jam, I'm always amazed at the quality those 13 years olds put out over there! You also know I won't buy Chinese products for this very reason.

Wonder what kind of support came with that baby :-0

If your paying $350.00 for a CMOY you need to change your Avatar title to "Don't know how to shop"!!!

I couldn't help it Shop, I love your avatar and I'm also sure you were talking Toma/Pico amps but the way it read cracked me up

I've wondered about that amp.

What are the internals?

Outer surface views tell me little about the amp itself.

I'm currently trying out several pictured here. I'll let you know what it looks like inwards soon.
