If you do not need the gain, the source variable output section can control the interconnect, and you like the sound then you should stop there.
Correct Clio,
Once again, please anyone who wants to put their head on the chopping block.
Using and quoting the laws of electronics (not just voodoo speak) what is not matched with the OP's PS Audio Dac 100ohm 2.8v output running direct into the Spectron's 50kohm 26db of gain input.
