I've reviewed most of the posts on the HE-500's and still don't have a good idea of what SS / Hybrid amps (for <$700) match them well.
My Millett Hybrid MiniMax matches them pretty well (maybe very well)... but... I'm wondering if any might match better - such as the Lyr, or EF5, or Audio-gd, or something else, like the Virtue Two.2.
From the results with my WA6 SEm, I'm guessing tube amps may not match them too well - it's got lots of power, but seems to need more current output, and lower output impedance to match them really well. They clip with it... and... I don't think its tube selection. I'm a bit surprised, since it drives everything else really well - Grados, Denons, Senns, ATH's, etc.
Maybe the Millett MiniMax is as good as it gets - which is pretty good... even my Shellbrook Maxi Moy is pretty good with them.
