Depending on the impedance match between the Zoe and JRDG 201,something like the BUF-101 from Space Tech Labs may be of benefit. In the case of a relatively high preamp output impedance, it'll both lower the input impedance the JRDG "sees", AND convert the Zoe's single ended output to balanced. Signal transmission over 3 meters will be no issue for any balanced cables. FWIW, I own the BUF-101 and it doesn't impart a sonic signature I can detect. The three tubes are cheap to replace and, in this use, should last a long time. I am also an owner of a Lector cd transport and admire the engineering and performance.
