I have recently purchased a pair of Sennheiser HD650 headphones and these are being powered by a Musical Fidelity X cans v3 from a Musical Fidelity KW250s all in one unit.
I don't particularly want to upgrade the cable but I need an extra 2 metres on the supplied 3m cable and Sennheiser don't appear to supply longer lengths.
I'm happy to upgrade but don't want to shell out a bomb for what I understand from other forums is likely to be a very marginal improvement.
Any suggestions?
