Or have a 50 cables running all over a studio (or across a stage), which is what balanced was designed for.

Bingo!

Sweet! Nice. I enjoyed the review. Always nice to validate your gear...

Not to sound like an idiot but I read a review of the Asgard 2 that lauded the no feedback aspect of it, what exactly does that mean?

I don't even get why they praise that as I assume most of them don't even know what it means. It's so irrelevant to the general consumer, but that's my take on it.

Basically, it's a circuit topology with high open loop gain, where the input of the gain device never sees or touch the output (feedback). If you didn't understand that last sentence, you don't have to worry about it. If you want to learn more about feedback, its benefits and drawback (or lack of), here's a glimpse of it.

It takes good design to achieve such low distortion as in the Asgard 2 without having to resort to negative feedback as an easy crutch and be subject to its drawbacks.

I think in Asgard 2 it's only used to reduce gain for IEMs... Not for any of its positive effects.

Yes, In the case of the A2, the positive effects of negative feedback are not necessary. And the negatives of negative feedback are avoided. Although in a careful and proper design negative feedback can do a good job. IMO, less is more.

Stereophile article (I've posted above) claims, that the amplifiers with a lot of NFB may look better on paper, but generally are less "musical" (whatever that means).

Just goes to reinforce my opinion that we can't and don't listen to specs.

I guess looking at the specs alone is like looking at human's weight, height and eye color only, ignoring millions of other known and unknown traits...

Kinda thrown every which way.

"Hey, our amps may not look too good on paper, and we might use some strange circuit decisions, and it's crazy expensive ...  but it's musical ! "

I can put a capacitor, some resistors and a OP amp with a headphone jack at the end in a toilet paper roll and call it musical too with a giant price tag. It doesn't mean anything nor does it gives it credibility.

Spec's are a tricky thing. They can be measured under ideal conditions, they can also be incomplete. There are many measurements that characterize sound, usually the tranient type of measurements are either not made or disclosed. How often is Transient Intermodulation Distortion (TIMD) disclosed? Almost never and it sounds awful. An inadequate design cannot use negative feedback to correct this. On the flipside there are many of us meat popsicles (Korben Dallas) that claim to hear what is not there or not hear what is there.
