I can believe that. I didnt like the wa6se driving my LA7000. It just seem to lack control of the driver. Loose bass and smearing on dynamic fast pieces. It seemed to lack control of the driver. It was great with the sen's that I heard on it.
I was trying to think of other powerful amps under $1000. I havent heard this amp, but you might try the RudiStor NX-03. It is only $790 and it has the power. http://www.rudistor.com/NX03-steel.htm
Yes... that's correct... it sounds like it doesn't control the HE500's well, and clips.
The NX03 specs do look ideal... if... it produces all the current output they may need. Perhaps... Rudistor has tried the amp with the HE500's - I'll inquire. Thanks for the suggestion. Though, I guess at 38 ohms of the HE500's, its power output would be something like 700 mW, which likely is a bit less than they really need (1.5 W at 16 ohms).
