I believe it's power on through the mains switch. =)

A really beautifully crafted set..

So... I had this CK watch case lying around...

And with some other spare parts, a nice PIMETA is born!

The board is a pretty maxed-out PIMETA with 12 stacked BUF634Ps and OPA637BPs on signal channels and OPA627BP on ground. DC offset is at 4.7mV on each channel. Teflon coated silver wiring is used for signal paths. The board by itself looks like this:

As you can see, the amp runs off 2 9V batteries. Hopefully I'll get some nice rechargeables soon. No other fancy features, just one pair of RCA inputs, one 1/4" output, and power on/off.

Soundwise, I'm very impressed! In comparison to my vague memory of my old maxed out META42, the sound is much more lively and dynamic. Compared to my maxed-out PPA, it's slightly less refined but somehow it's got a good dose of fun factor in its sound. Sub-bass isn't as powerful as my PPA either but it's still very good.

Anyway... I'm happy I have a decent battery-powered transportable amp now. With my battery powered USB DAC, I can now go anywhere with my music! Not that I'm going to do that often, but at least I have a nice amp that I can perhaps lend to people and bring them into this evil hobby. :veryevil:

Wow, the dynamite is one amazing piece of work. I can only imagine how it sounds... mmm... Beautifully crafted!

Very impressive Dynamite amp! The thing is huge - what's the power consumption with those fets?
