Looks like they have copied a few ideas from Audio-Technica AtH-HA5050H DAC/amp. Impedance selection as well as VU meters.

Yes, and it has a balanced headphone out too. The Mojo is likely to sound better but the ZX300 is a really good all in one DAP. It has BT receiver so u can stream music from your smart phone to it.
I owned the Utopia for a year before selling it. I love nearly everything about especially how dynamic sounding it was, but the size of the soundstage really bother me at the end and decided to go back to the SDR mod HD800. YMMV.
I would get a used GS-1 and upgrade the old dynalo boards to Dynalo plus over the Gilmore Lite M2 with the brick power supply. Justin charged me $200 for them and the overall tone is warmer which should match a little better with the Utopia. You can also buy the GL2 and find a used Headroom DPS power supply instead of using the supplied brick psu for better sound. Best is to go with the GSX-mini or Doug ECP DSHA-3F to improve upon the smallish soundstage.
Yes, Justin did confirm it and I did try it and hear good improvements. The Astrodyne PSU is also another one that you could try over the supplied brick PSU for noticeable improvement.

You can make it better if you can find a Headroom DPS power supply to power the Lite MKII instead of the brick.
I spent about a week with the GSX mini and it was fantastic sounding with wide-range of different headphones.
He/She will love it Chris. Hard to beat the Mini Dynalo. I have the GSX Mini on loan from Justin and I'm splitting hair to hear difference. Thank you so much for making one for me.
