JDS Labs Atom Amp+ and DAC+ HEVI editions (more substantial metal casing and volume knob). Items have been lightly used but show minimal if any signs of wear (see photos). I’m the original owner; items will be shipped in all original packaging with original accessories (power cables,

　　specially built RCAs for connecting to the two while stacked, and USB type A to B with ferrite).See links below for additional details.https://jdslabs.com/product/atom-amp/?gclid=EAIaIQobChMInY-jpPfGgAMVKBitBh2Kfg-lEAAYASAAEgIIhfD_BwEhttps://jdslabs.com/product/atom-dac-plus/?gclid=EAIaIQobChMIguDsrvfGgAMVKzytBh3hRgGWEAAYASAAEgJhzvD_BwE
