Refusal to take responsibility.
Hi, Just thought I would make a note here of your handling of my issues. I ordered a pair of HD6xx headphones and then earlier today recieved the package. I drive to go and get it, as I like in the UK I had to pay import tax and handling fees. These total £47.92. The breakdown being £35.92 in tax and £12 in fees. These taxes were calculated of the shipping label of the box, which marked the shipment as the 6xx headphones of $199 value. Before leaving the parcel depot, I open the box to find a $35 lord of the rings mousepad. So now the problem is not only do I not have the headphones, but you have marked the shipment wrong so I have paid £47.92 fees for the handling of the mousepad. Which would have acrued £0 of fees if marked correctly as it is under £135. I go back to the desk but as I have already paid the fees I am unable to reject the shipment, but as the box said 6xx, there was no way for me to know before opening it. I contact support and they offer me a replacement, which...

Supporting truly balanced signal pathway throughout would shoot the cost through the roof, for negligible improvement. See Bruno Putzeys' EDN article on why having truly balanced signal path isn't necessary. "Symmetry is useless". " Differential transmission of audio doesn't mean you need to make a symmetrical voltage " https://www.edn.com/design/consumer/4429968/2/The-G-word--How-to-get-your-audio-off-the-ground
Then in another post claims its balanced when compared to the Monoprice 788? So which is it balanced or not? I dont think you can have it both ways its either balanced throughout or its not balanced.
AndrewMason139Follow THX Ltd. Analog & Power Engineering Expert 3D joshy_bennettHi @joshy_bennett . Compared to the Massdrop 789, the Monoprice 788: -uses the same AAA technology -788 has less output current/voltage/power -788 no true balanced output (has XLR-4, but it's only driven single-ended) -788 includes a DAC selected by the Monoprice team. So it depends on what you're looking for.
Everything on this drop suggests the 789 is balanced. The engineer mentioned phase inversion vs discrete DAC's per channel, there's a difference in power output etc. But, the 789 was supposed to be a tweaked 788, or at least that some people's impression. The differences just need some clarification.
There's just a lot about this drop that simultaneously impress me, and give me pause. I'm gonna have to think on it a bit longer.
With that good news (and the fact that the unit has a DAC with a full array of digital inputs... and Dirac Sensaround processing on-board), Monoprice's 788 is looking quite promising. Shame they keep pushing the release date back, though.
I followed-up my original question by asking if the circuitry from the amplifier to the output was fully balanced (differential). Unfortunately, Monoprice chose to delete my questions from the page. I was looking forward to this upcoming Monoprice DAC/amp, but this kind of behavior doesn't sit well with me.
That's in contrast to the 788 from monoprice which isn't even running phase inversion. It's supposedly a standard, single ended output with a 4pim xlr connector.
