I own and run a Shanti - I think I mentioned more than once.

Allo doesn't disagree. They "hear" a minor difference. That's how I recall it. Let's not talk under what conditions.

They want to sell the product that very well fits the picture of the crazy audio crowd out there. And that's gotta be a linear supply.

Top high end audio gear manufacturers use SMPSs since years. That linear thing is a myth.

Once more. What matters is the implementation.

If Allo would have attached the same supercaps to the Nirvana output, which wasn't done, and I guess wasn't done on purpose, we wouldn't have this discussion. That's simply been a marketing decision. They needed to stay in the iPower ballpark.

And the Shantis "incredible low impedance" - a nice try. Have you seen
any transient response measurements?

Yep. Supercaps can a have quite a low ESR. At the soldering pins. But what's left of it after a 5 foot cable and some el-cheapo connectors and adapters. I never received an answer on that question.

The first thing I've done, was replacing and shortening the Shanti cables and of course getting rid of the plugs.

Enjoy.
