You can't look at toroids and capacitors and dictate it's limits because you do not know their values and tolerances.
I can only provide what to expect based on design.
And not to change the subject too much but Taramp's offers unconditional warranty services, something most internet brands currently do not do.
If it fails or breaks, they will fix it for free, no questions asked within the first year of purchase.
I can say though it's not like each brand is purchasing from the same pot so when brand A cost more than brand B, there is a clear reason.
This isn't necessarily true.
The designs between Orion and DC are different so they are either coming from different sources or are engineered differently clearly.
If you are comparing Orion 11k vs any korean 5k, based on design, the Orion is designed to handle more sustainable power on a 12v system.
Some korean brands pride themselves with offering 18v capability, something most users do not care about and this feature is part of price hike.
In all honesty, Orion vs DC, that's comparing Mainstream vs Internet brand.
DC is big but i'm sure they are not mainstream in terms of quota.
Taramp's, Soundigital, Stetsom, they are all mainstream based.
Taramp's manufactures, on average, 180,000 products annually.
Good luck on our popular Internet brands in the US ever coming close to that.
Brazilian companies have it made because they are buildhouses and they brand their own work.
That cuts 1 middle man out right there.
But that's a little FYI.
