>recabling is usually too expensive
You can get a decent cable for like 20 bucks. Unless you have Sennheiser and need their proprietary connectors. Then it's ogre because those cables are usually more expensive. Never buy the headphone manufacturer's cables because you'll just overspend.

This. Unless you use low sensitivity headphones that need more power there's no need for more than that dongle.

>speed of driver
It's the same driver type. it's not "faster"
>scales also very well with different sources
660S2 is much easier to drive than HD600. "Scales well" is a meme by the DAC jew. A $1000 amp won't turn your headphones into an HE-1. All HD6X0 HPs have a more pronounced midrange compared to HD560s, that's true. But HD600 is still the best out of all all headphones in that line. HD660S2 is overpriced. An Aeon costs about as much and is superior.

It's decent but mine used to freeze once in a while and I had to replug it to fix that. Maybe just a bad unit. I returned it.

Enjoy your planars, anon. I had a similar experience going from gayming headphones to a SHP9500 many years ago.
