had my HD600 for about 20 years, still use them every day with the laptop, Fiio ka3 and a balanced cable, really thought they were my end game until I bought the cheapest stax set the srm 252s and the L300s with the socal mod for a bit more bass.

Once you hear electrostatics you will either go not for me or wonder how you can save for a better energizer or further up the line, though these will do very nicely for now...
