I'm going to have my DT1990's recabled to use with balanced amplifiers. But first I need to buy a balanced amp. Burning money.
Don't really know if it will give any improvement in the sound if they are like the older DT-770/880/990 where I made them dual inlet cables so they could be run balanced, it made no difference in the sound to me or my friends that I did the mods for. Balanced amps that were use: Liquid Carbon, Liquid Glass, AudioGD Master 11, and WA22.
