Have a look at the photo below.
All new printed circuit board. New pot and switch. Cool blue LEDs for the volume knob.

On the right you'll see the wires leading to headphone jack.

There are 3 transistors on the PCB, don't know yet what they do, maybe power-on pop suppression.

Seems to be the same output section as the Sonic Gen-1. There is a 470uF cap on the PCB near pin 1 (lower left of photo). Might be the power cap AKA "tank cap."

I'll check into all this when I get a chance. Just thought y'all would like to see the new beast.

more and more. input caps better than the original? all waiting for the sound evaluation.

Thanks Pano. That was faasssst shipping to Hawaii.

This is looking like a step back, is that 9 wires to the headphone socket

. I thought the 470uf cap was meant to be as close as possible to the VDD1 & VDD2 pins.

Not for me, sorry for the negativity...

You can say that again!

I don't know yet what's going on in there. I do agree the placement of the 470uF cap is odd, if indeed it is the tank cap. However, it does have a thick trace running from it. More important are the small film caps that should be right at the pins.

Yeah, there's a lot more wires. I will sort it all out when I get the chance. The PCB is larger and easier to get to, so that is an advantage for modding.

Forgot to mention that the Gen 2 comes with a mini to RCA cable and an RCA to mini adapter. Very handy for connecting to your CD Player, but bit awkward for iPod style use. I think they should also include the spiral mini/mini cable for the iPod crowd.

I don't know, that was simple so bad quality that it was the first I threw out before modding my t-amp. Next was the crappy binding posts.

Hey Pano . . . where'd you go? Some of us are dying to hear more about this. How does it sound? Did you actually mean there's a headphone output? If so, how does that sound?

Where'd I go? To Denver to attend the Rocky Mountain Audiofest, of course!

Even took the little Gen2 amp with me. Alas time did not allow me to test it.

Really too bad.

I'll be looking at it more closely in a few days. Look for more info on this thread. I don't expect it to be much different from the original, but you never know.....

Kensai · 19th October 2007, 08:44 PM

Cool, Pano. How'd that go for you? I miss Colorado . . .

Anyway, all I'm looking for is perhaps a little better bass performance. That plus a correct PS included would be enough to make me look at this price. The headphone jack, if it doesn't kills SQ would be a clincher (I suppose that having it d-amp the headphone out would be asking too much, eh?)

Thanks for guinea pigging for all the rest of us.
