Please, can you shed some light on this?

Under this name I have seen so far only a model with the old Spring1 technique but not with the new Spring2 one.

Are both built up to the same standards by the same manufacturer or is Armature somewhat inferior to Holo?

 

Thanks

Hi Matt,

 

The Asterion is a slightly tweaked version of the "old" Spring 1:

 

L’Armature Asterion est une version customisée du Holo Audio spring (en level 1 chez les distributeurs qui vendent des versions gonflées, avec notamment un transfo en argent au level3, ajout jugé discutable par le staff audiophonics, qui est resté avec la version standard, très homogène). Armature a fait quelques modifs, avec une entrée USB XMOS plus musclée et un afficheur différent. Il semblerait également que les connecteurs soient différents.

Best,

Thanks Ricardo,

do you know if they will launch a tweaked version of Spring2 as well and if yes, when?

Sorry, I have no idea if they intend to update the current version.

Maybe you can send them an email: http://armature.audio/contactez-nous/

I asked if they have plans to launch a tweaked version of the new Holo Spring2.

 

The reply:

"To be honest no, since for us the gap is at best minimal."

Apparently the RME ADI-2 is not really NOS. They only called it so,

 

it is the 'Super Slow' AKM FIR filter which shows a stepped response like NOS. Many AKM chip devices can select this filter, are they all NSO DACs? I think not.

If I'm not mistaken if you feed it a stream at the highest possible sample rate it will not oversample so it is NOS, but fron what you say it is not filterless.

My TEAC also has a FIR filter for DSD but I think that it's an analogue filter. And crossing quite high.
