Up for sale is my RAAL Requisite SR1A headphones, a matching black Jotunheim R amplifier, and the convolution filter from Accurate Sound that applies calibration to further improves their performance. I also have a (pictured) RME ADI-2 DAC available that makes an excellent match for this setup. I purchased these last November. They're great, but speakers are going to work better for my purposes.

Local pickup in the NYC area would be great (I'm in Chelsea), but I'm also happy to ship elsewhere.
