JDS Labs C5 portable amplifier appreciation + discussion thread (check 1st post for review) - Page 10

 It's 2/15 and they can't put the preorder up fast enough for me! I'm excited for this amp as it will probably be my first portable amp. I just got a 5.5 gen 80 GB iPod video to go with an amp, and I'm heavily leaning towards the C5 now. Don't make us suffer too much longer, please !

doesnt "open source" mean that the design is available to everyone, to do with as they please?

and as for "falling of the plant" - hopefully working on the ODA

No, open source means anyone can do anything they want with it if that's what the author permits:

Making design alterations for a smaller odac would be altering or transforming the work.  If they had permission that wouldn't matter, but I was talking to john at jds, and he hasn't heard anything lately from nwavguy... :-/

No, open source doesn't always mean anyone can do anything they want with it.  It has stipulations based on what the author permits:

What I had in mind wasn't making a smaller odac. The original size of the odac board is already very small. what is i'm thinking is that john could probably place both the odac board and the C5 board side and side/ on top of each other, join them together with the right connections, and design a whole new case that can fit both boards inside. the final size won't be too big either, and it should still be portable.

Oh I just had a thought: The S3/android phone's usb port might not have enough power to power the odac. It will have to be designed to somehow run off the amp section's battery, which will violate the open source t&c

Ah... I see.  Yeah, I was thinking about that the other day too.  I thought you meant revamp the board to shrink it...

It's on their blog now!!!

I'm surprised, I thought there will be a all-black version, since John once mentioned that it's cheaper and the quality is better for black than for silver.

Just going off specs, is the general consensus that this amp will out preform the new FiiO E12? I like the digital stepped attenuation, and the stronger bass boost for when I really want that extra kick. I also like the output impedance, should play nice with most of my stable, does anyone know the output impedance on the E12?

Check out the comment on the JDS blog; Yes! 100% neutral!

less that .5 ohms

I shall wait for reviews myself, no disrespect to this product but the FiiO is $60 less than this, so if there is some consensus that the differences is slightly in favor to the C5 then I will go for the cheaper amp
