lol the original sound of M50W is already quite resemble with the tonal type of stock hd650.
it's warm, punchy bass, and quite balance overall. Give it a try and u might feel it's actually good enough, and which in my opinion don't even need much tweaks, just make sure you have good source to feed it.

and i don't think VDH will suits M50W. the M50W is already warm but still maintaining quite good speed in the sound signature with stock cable. changing it over to VDH such as D102mk3 cable will slow the sound even more, add more colour to mid, and even much warmer, which is a big no no to M50W imho.

If you have any suggestions on dealers who are well versed in selling audio products, let us know and we will contact them

hahaha.... budget bro, budget

i was actually leaning towards M20W, M50W was a lil overbudget... but after listening to it in person, done deal straight away LOL
