I did post somewhere that I popped the iMod into the dock in the Amphora, and then used the Amphora as a pre-amp to feed the P-51 mustang with an RCA-mini interconnect. And the P-51 sounded pretty much like it does when running my iMod/pVcap dock directly into the P-51. If anything it was slightly better with the iMod/Amphora as pre-amp, because the signal didn't have to go through both an LOD cable into the Vcaps and then through a mini-mini to get into the my Mustang (the number of IC was reduced from two to one).

So, the Amphora as a pre-amp took away nothing from the sound of the amp that it is driving, at least when that amp is a P-51. Later, after burn-in is done, I will hook it up between my PS Audio Digital Link III DAC and Woo GES and try it as a preamp there too.

In the image that you posted, is the blue disc attached to the goggles strap (about where an ear might be with the goggles worn) an underwater earphone?

If so, how's the SQ? I'm guessing that the soundstage would be challenged with there being only one.

Not sure. More info at these two sites:

Waterproof Scuba MP3 Player: Entertainment under water

IRiver: Waterproof MP3 Player is iRiver, Dives to 200 Feet Under the Sea

PS: I already own a waterproof bag with in ear headphones that my daughter used in Hawaii to listen to while swimming with her Nano. It works.

The Ibasso site will accept your order even though they say out of stack for the D10. Had mine in about 10 days after my order. Great amp, great service, but website needs some updating and polishing up.

Thanks much !

Can you tell us something about the circuit design Vinnie?

From the picture I can see what looks like one opamp - that appears to be the only active component?

 

[scootermafia]

This is a steal, packed with RWA boards and all...damn.

Yes, I would like to know more about the circuit design as well, please.

I would be very interested in more description of the circuit also, please. With other amps, descriptive information like: all-discrete or uses-integrated-chips, the kind(s) of integrated chips used (in both gain and output stages) as well as the Class of both gain and output stages, and the like have been useful in describing and discussing the performance of an amp, especially in relation to other amps. If you'd be inclined to offer such descriptive information for the Amphora, that is.

Is there much stock left of the regular Amphora? I'm thinking about getting one (possibly with some ALO cable) but I don't want to discover that there's none left.

Hi guys,

I apologize for the slow response... I have not check this forum in a couple of weeks.

Thank you for your interest in the circuit design / topology, but it is all proprietary - so unfortunately I cannot disclose details.

Hi Gazza,

I would email Ken if he as any left in stock. He is making more enclosures and I have more boards and parts on order. Hopefully we will have them in a few weeks. A few of the parts are a real PITA to get!

Can you at least post the little bit that you told me in a PM, or let me post it?
