. . . ahm . . . whoops, sorry, got carried away . . what I was thinking of was 'rolling valves'. Thinking about all the posters on here who are trying to change their hifi sound with new amps, speakers, then cables . . . often with expensive and mixed success?
How about moving on to some real amplification . . . proper amplifiers, modern valve amps are the bees knees . . . then you can not only change your interconects but the valve quality and manufacturer as well, its called 'valve rolling'. There are companys out there dedicated to supplying, valves, dozens of different makes at all sorts of prices, offereing all kinds of sound, tweakers heaven . . .
I'm waiting for a matched set of 4 to arive, 'KT88 Gold Lion's', a re-issue of a vintage valve with a reputation to die for, at a fair price compared with cable prices per meter!!!
