Sorry no pix. His Denon AVR doesn't have enough power via the headphone jack to power his 300 ohm HD650's. My RSA Green Hornet wasn't a very good match but the iBasso D10 was slightly better. In both cases, the volume was cranked all the way up for a not so loud volume. He liked it best connected to the Bottlehead S.E.X.

Then I showed him why I like my easier to drive HF2's and 840's. He could tell the difference. I also warned him to make sure he brought good source material. I listened to his Minidisc and complained of hiss which he didn't notice, until I pointed it out. Then I played a Jack Johnson track (which always seem well record for some reason) from iTunes and he could tell the difference. I told him to listen to his CDs to make sure he wasn't ripping poorly mastered CDs into lossless format. Garbage in, garbage out.
