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...

1) I like separates... the flexibility they provide is worth the extra space/cost to me. Not going to state they are "better" per se, just like being able to swap smaller pieces of my audio chain.
2) Do you have balanced or balanced capable headphones? If yes the THX makes 6x the power into 32 ohms and 8x the power into 600 ohms. The THX also puts out almost 2x the power in 32 ohms and 600 ohms in single-ended. This extra headroom may be handy if you have hard to drive planar magnetics or 300-600 ohm cans (Senn/Beyer).
3) The AA R-2R is an interesting topology, lots of subjective opinions on it having an inherently smooth characteristic.
4) The M9XX and the AA both do DSD
5) AAA has 3.5, 6.3 and XLR outputs, negating the need for any adapters.
In the end only you will be able to decide, for me I like separates and I own fairly inefficient planar headphones so the stack would be the way I would go . The grace is a nice piece of kit but may not be the best pairing with extremely efficient low impedance headphones or hard to drive cans. What headphones are you using?
