Effective shielding against RFI and EMI are very important to me, since I live in a spot where RFI is intense and, perversely perhaps, listen almost exclusively to LPs. I’d found Nordost to be excellent at rejecting RFI/EMI. So is TARA Labs.
 The Zero interconnects are warranted against defects for five years, and, under a separate warranty, guaranteed to maintain their vacuum. The original purchaser can send his Zero interconnect to TARA Labs for a free diagnostic (including evaluation of vacuum condition) at any time during the first three years—and for a small service fee any time after that.
