Aimpire the Topping D10 bait and switch fake.
Necrobump! Six or eight months ago i ignorantly bought one of these from the local freight salvage dealer for about $28. I'm gonna go out on a limb and suggest that the opa2134 chips in the photo were fake, but mine came with a socketed ne5532 and a pair of surface-mount tl062 in the...- ericj

Mosfets do blow, and they often blow as a dead short. If you have a component tester, you should be able to test it. Other than that, maybe post pictures of the boards from multiple angles, perhaps something is installed wrong.- ericj

With no power connected, can you measure resistance between the two red primaries?- ericj

Bijou All Tube Futterman Headphone Amplifier
What in the heck do you mean by "twisted red wire goes to ground" - where do those wires come from? You sure none of the wires coming out of the transformer are damaged?- ericj

Red-yellow should be literally ground. It's the center tap between the two red secondary wires. So, double-check how the transformer is connected to the power supply board. Maybe post pics. And make sure there's nothing shorting some pins on the bottom of the board.- ericj

The Stax Thread III
Yeah, you need a power source to generate the high voltage. And you'd have to build it yourself or pay someone to do it. Spritzer briefly sold an srd-7 pro board. I have an unfinished design that i may revisit but since i don't have a lot of high-bias stats it's not a priority. Another problem...- ericj

Why doesn't anybody like the Denon AH-D600
Necrobump just to say that I picked up a gimpy pair from ebay on a whim. No pads, damaged plug. Threw on Geekria pads and put a new plug on the cable. The 4-pole plugs sure are fiddly to solder by hand but I had it sorted in about 20 minutes. I'll make it permanent as soon as I figure out...- ericj

CCA in ear monitors Impressions Thread
I feel like the quantity is fine, but the quality, surprisingly enough, isn't as good as I'd expect for $35.- ericj

CCA in ear monitors Impressions Thread
After spending significantly more time with my CCA C12 I've come to the conclusion that the bass just isn't up to my standards. I like bass that goes low but is tight and clearly defined. I accept the slightly bass-lean signature of single-armature etymotics and sometimes goose 'em with EQ...- ericj

Findings with regard to repair of Monolith M300 planar canalphones
Those of you who recognize my avatar know i have a bad habit of buying broken headphones. So i pulled the trigger on a "right side not working" M300, pretty complete set, $40ish shipped. These really are a half-baked design, if that. But anyway. Construction method is glue. Cyanoacrylate...- ericj

indie hip-hop, alt hip-hop, revolutionary rap, turntablism
It's popular in my generation (gen-x) to say that good hip-hop died in the 90's. And yeah, once upon a time i was a white boy in the burbs listening to Run DMC. Commercial hip-hop really has gone some pretty horrible places over the last 30 years, but i discovered a couple-three years ago...
