I would have preferred a comparison between the balanced/unbalanced outputs, and also one between the MSB set to output a fixed level (and using a pre) and the same using a variable level.

I think the main questions the potential buyer faces are if the DAC volume control is good enough to get rid of a good preamp ("good", as in a pre usually included in systems that can take benefit of a $7,000+ DAC) and which trade-off is better if the rest of the system is fully balanced: using the "native" SE outputs or the "artificial" XLR outputs.

Also, since I have never listened to the DACs used for comparison (and even do not know how their price compares to that of the MSB), the only valid information I could gather is from the Measurements page!

Sorry for being candid but I really expected more than a nice rant about Bee Gees and tiny buttons with a green/red glow.

This is my favorite DAC until now. I've never tested / reviewed another dac to sound as natural and still with an incredible amount of detail within a very holographic / 3d sound presentation.

These being said, I managed to buy one for myself. I have tested the single ended outputs vs the balanced outputs ( with Audio GD Master 9) and I think that the single ended outputs are better overall with more detail, focus, better instrument separation, etc. This is a dac that excels on single ended, as it really is a single ended DAC. The balanced outpus adds some other circuitry that takes away from the transparency of the sound, to transform the single ended to balanced. However, I am not sure that balanced design is better than single ended design. I've heard absolutely superb single ended dacs which sounded much better than some balanced dacs. I think that it depends mostly on the matching and each component in the system.

So the main problem will be with the amplifiers you use, as some of them are of balanced design, and might sound better on balanced inputs than on the single ended ones.

All major amplifier brands moved to balanced designs. Does this mean the buyer must invest in XLR input? And what are the repercussions if not?
