Thanks for the review! I'm quite interested on this DAC and thinking of pairing it with the E9 as my amp. Do you think it will be a good match? Also sorry for asking such a stupid question but how do I connect this DAC to my E9?

I think the E9 is incompatible with the HRT Music Streamer II due to some strange clipping issues. You may want to contact HRT to see if they know. Maybe they released a firmware update. I can try it out soon and see if the problems exists. Haven't tried it with my E9 yet.

BTW to connect it to the E9, you use dual male RCA to 3.5mm cable. The HRT has two female RCA jacks. The E9 only had a 3.55mm input on the back. The HRT doesn't come with cables, but I got mine from Monoprice for a few dollars. You also need a USB cable to your PC.
