internals 47 labs 4717 integrated

[MIB]

On a dutch audioforum hifi.nl a review of the 47 labs 4717 integrated amp was posted today, including some pictures of the inside. It made me wonder about the pictures of the gaincard internals that float over the net. If this diy-looking amp is the real thing, than the gaincard pictures might just as well be.

They don't look like nice textbook solders to me.

Maybe that's the secret to their great sound

Does anyone know what they are saying in the review? The only thing I could make out was "Dire Straits" on page 2. I guess somethings are universal.

Cheers,

I wouldn't worry about solder joints

What I find interesting is that the pins on a chip support the whole PCB (including caps). Even more interesting is the way the chip is mounted. As you see the enclosure is thin sheet metal, yet there is no srews visible on the outside where chips are mounted. It seems like a piece of thicker material is attached to the walls and there, a proper thread for mounting screw is made.

But I like this design, very simple, yet functional.

The reviewer is impressed, but the amp was much better with classical music than with pop/rock. So the amp is recommeded for people who listen to classical music 90% of the time. The lack of colouration in the mid-band didn't work out with pop. This is roughly the contents of the dutch text.

I wouldn't be surprised with that. The case introduces quite a lot of resonances. It's not that 47Labs want to get rid of them, it seems like they don't. Those resonances may actually improve the way one might perceive classical music, but with pop/rock it may sound like early versions of surround sound

Wonder what kind of internal wire they use...

Piece of overpriced cheap junk produced by even cheaper labor power.What a rip-off and marketing hype. .
I know, nobody forces anybody to buy it by the fret to his life but this kind of customer abuse makes one mad anyhow.
Shame on you Shigaraki san.

It's impossible the pictures above to be the Gaincard. The Gaincard has each channel totally independant in a separate compartment (see the picture). Above pictures show the two chancels in one compartment. And it doesn't look like a production unit at all. It could be a review of a Gainclone, though.

The review is for Shigaraki which is "budget" version of gaincard. Those are two different products. Check sakurasystems.com for more info.

I stand corrected. My fault.
