If you are looking for an OTL amp try the 339 by la figaro its great with the HE-500 as well, you will need to do some tube rolling though
In my experience OTL tube amps and planars, particularly the he500 do not pair well at all. They simply don't output enough current at the lower resistance of modern planars. As such, the he500 sounds bass light and thin, not very full or musical at all. OTL and planars, at least in the case of the he500 don't mix well.
