PASS DIY Headphone Amp - WHAMMY
Jul 29, 2020 at 12:46 AM Post #196 of 274
The case is from AliExpress and laser engraved. The rear looks better because the laser can burn off the black anodization cleanly. The front is highlighted with some black graphite or else it wouldn't have the same contrast.

I'm not worried about the inlet connectors, just don't stuff your pokey bits into the receptacle or open it.
would you be able to link the case or maybe the name? it looks really clean. contemplating building one of these.

I still have my old Lehmann Black Cube Linear clone that I use as preamp and headphone amp duty. I was mainly thinking about selling it for the cash not because I found an upgrade.
Yes still for sale, there's a Burson V5 in it and a LM4562NA that I haven't tried yet. Initially built I used the cheap opamp from the BOM, it does its job but any better opamp will sound better.
What are you asking for the PASS WHAMMY $ ?

Does anyone have any spare 71-RN55D3300FTR? It's all sold out online. I just need 2 thanks!
It looks like that number is the Mouser Stock number, while the Vishay Dale part number is: RN55D3300FRE6

Mouser has 952 in stock for immediate shipping. 21 cents each, 42 cents total + shipping $7.99:

Has anyone got a recommendation for a good dac pairing with this amp? Would it work better with an r2r like the ares 2 or something more like the topping d90

I was involved in some DAC testing involving 20 high quality DAC’s and Topping did well against many more expensive DAC’s. Personally I like the Schiit Gungnir and Bifrost 2 with the Whammy.

Whammy up and running with an OPA2107. Waiting on a case to complete the build.

I finally got my Whammy together. I designed and built the case myself. It’s all CNC gunmetal grey anodizer aluminum and walnut.
