Not even remotely similar to Anax mod. Balanced cable costs $350 by itself from Sennheiser. I can't name dealers because they are accepting pre-orders through direct contact with email only at this time. You won't have to wait long though.
Cables are overpriced (you made my audiophile price gouging point), and yes they clearly didn't use an annax mod but the results are similar, tame highs and add some warmth. Not the same approach, but similar in outcome.
