These fabulous cables don't come up for sale very often.
Purchased new in Summer of 2012
I have 2 pair of these beauties up for sale. These are the Gen1 HFTN and Gen2 IC Cable. They sound exactly like the newer version! The only difference is the HFTN is now located inside the barrel of the RCA plug.
From The DNM Wesite:
The DNM RF termination system, named "High Frequency Termination Network" (HFTN), is a precision circuit that controls the radio frequency (RF) load presented by the cable to the amplifier. The HFTN terminates the cable at the radio frequencies that are generated by the amplifier's feedback system.
Audio frequency signals are not directly modified by the HFTN but the amplifier/cable RF interface is so greatly improved that the amplifier's feedback accuracy is enhanced. This gives a substantial increase in audio clarity.
