I was told my previous attempt to share my pictures had failed. Here’s another try;

Thanks for the photo. That is nicely done. Gotta love purple wire.

I completed my NOIR build earlier in the week. It was a fun build. When I plugged it in and listened to it thru a DIY pair of bookshelf speakers (old Madison design with Vifa drivers) I was totally floored at the articulate and nuanced the sound that emerged (Roon--> RP3 endpoint--> Hifiberry Dig+ Pro Toslink --> Schiit Modi MB --> NOIR -->ACA --> Speakers). I had never heard those speakers sound so good. Same result with Audeze LCD-1. Color me impressed.

Last year when I built my WHAMMY I used a red case with red Riverstone knobs I bought on Amazon at $10 for a pair. I used the other one on the NOIR. I think the red knob on black case looks terrific.

Congratulations on a very nice build, bchassy! The red knob does really pop against the black background of Noir. Maybe you'll want to also install a red power on/off LED to complete the look ...?

BTW I just ordered a pair of Audeze LCD-X's myself. Really looking forward to pairing them up with Noir (plus a couple other headphone amps, for comparison)!

Mark:

I neglected to thank you for good work on the Noir and this thread. Really helpful. Thanks.

The red led is a good idea. If I get it done I'll post it. The one I have in there now is more orange than yellow but it's definitely not red enough. Red and black are a great color combo.

I loved my LCD-Xs but sold them off last Spring for reasons I do not remember. I have new LCD-1s. They are extremely light, feel great, and to me at least they ooze quality. The sound is surprisingly close to many higher price planars. To my aging ears at least. That said, I am sure the LCD-X will sound great with the Noir.
