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.

Perhaps to you. I'm always amused when folks play the role of apologist to a manufacturer's product decisions. I hear the same silly explanation for speakers having bi-wiring posts. :)
Have you seen any transient response measurements?
I couldn't care less about simplistic metrics. What I hear is far more important. As for DC cables, both of mine are one foot and use low inductance star quad construction. What I hear is better dynamics, especially at the PP end of the scale.
very important
there are many components which determine that.
Speakers having diaphragms with lower mass than the air around them is one important factor to me.
Yep. "You couldn't care less."
Sounds pretty ignorant to me.
You're fighting my arguments about lower impedance and better transient response as objective, thus measurable, quality parameters for power supplies and then you're telling us, that you actually did lower the impedance and improve the transient response in your setup by replacing the cable.
...obviously without realizing what you're doing.
Watch your attitude!
Enjoy.
to reading charts. There are few metrics with direct correlation to what we hear.
To each his own. Even grumps like you. ;)
