Now would be a good time to experiment with bulk small gauge solid core copper wire for a pittance, as you would be using short runs (throw stranded wire into the mix as well, but up the gauge a bit).
If 26 gauge scares you (my 47 Labs OTA is 26) try 22 gauge...
I've used the OTA succesfully with more contemporary/normal amps/speakers than those listed in my system (Carver MXR130/Musical Fidelity X-A1/Pilot 232/240 - Magnepan SMGA's/Reynaud Twins II/ADS L880/Klipsch Chorus II, just to name some).
I've only tried the OTA in short runs (approx. 2') with my current system and did not notice a difference, but only tried it for a few days as I was concerned about our cats being able to access the Bottlehead tube DH/SET 2A3 mono blocks and their high voltages (the BH tube preamp less so).
I would suggest using bare ends, sans connectors, if you consider doing so.
Also once tried the OTA in long runs 25'-30', or so, and it sucked - so this type of cable definitely has it's limits.
