Pros: Dynamic, musical sounding, revealing
Cons: Deep bass could be somewhat better defined
Modified these to balance with silver/gold wiring and Furatec XLR plugs.
After a fairly long burn-in (>100hr) of the cabling and used on the Rudistor RPX-100 dual mono balanced solid state amp these sound very musical and dynamic. Much micro detail comes out and there is a good 3d stage imaging. The sound is very involving and intimate, providing foot-tapping and sometimes goose-bumps. Eargasm?
Definitely a step forward compared to the standard non-balanced version which did not impress me much.
