Description

The Japanese company Aurorasound is now globally renowned for its high-quality phono preamplifiers. To complement these and also offer a high-end solution to owners of excellent MM input, Aurorasound initially offered the Aurorasound SP-03L transformer, now joined by a more democratic model, the AFE-12.

AURORASOUND AFE-12 MC TRANSFORMER: DESIGN


The Aurorasound AFE-12 transformer is housed in an attractive non-magnetic mu-metal case with front and rear panels made of anodized aluminum.

This AFE-12 transformer is fully shielded and immune to electromagnetic interference.

Inputs and outputs are made with high-quality gold-plated RCA connectors. In the middle of these connectors is a lever switch, allowing for impedance selection. The overall construction is remarkably well-made and instills confidence.

AURORASOUND AFE-12 MC TRANSFORMER: COILS


The Aurorasound AFE-12 transformer is, of course, completely dual mono. It is equipped with two transformers specially manufactured by a renowned Swedish manufacturer to Aurorasound's specifications. These transformers are wound with three different windings.

This allows for impedance selection. A selector switch allows choosing between Low, Medium, and High depending on the chosen low-level MC cartridge impedance. The 26 dB gain provided by the AFE-12 allows it to be paired with MM preamps with a gain between 40 and 50 dB, depending on the actual output level of the MC cartridge - please consult us for more details -. The announced bandwidth of 20 Hz to 50 kHz at +/- 3 dB is remarkable!

The internal cable has been optimized to be as short as possible from inputs to outputs. The inside of the case is dampened with a large quantity of "pure" cotton, as is also the case with the Aurorasound SP-03L.

AURORASOUND AFE-12: TESTING AND LISTENING


It seemed judicious to us to pair this small transformer with the Aurorasound Vida Prima, then with the phono input of the magnificent Aurorasound HFSA-01 integrated amplifier.

From the first tracks, one realizes the musical contribution of a step-up with a low-level MC cartridge. The playback is airier and more subtle. It feels like you hear more detail even though there is no sense of clarity or aggressiveness.

This AFE-12 connected to the phono input of the Aurorasound HFSA-01 integrated amplifier works wonders... you can even add a high-level turntable and MC cartridge to this combo.

The surprise came when using the AFE-12 transformer on the MM input of the manufacturer's best-buy, the Aurorasound Vida Prima. Indeed, by adding an element and a cable, one might think that this would have a detrimental effect on dynamics and transparency... Well, not only are these aspects not affected, but they are actually enhanced! Musicality is elevated with realism, nuance, and subtlety. There's also a significant improvement in dynamics and impact.

This "small" Aurorasound AFE-12 transformer is a gem! Highly recommended!

SUT très performant

Dans ma configuration hifi, le step up vient s'intercaler entre une platine Rega moderne et un ampli Rega dernière version du Elex. Je retrouve le plaisir d'utiliser l'entrée phono de l'ampli, la seule solution pour amplifier une cellule Hana SL par cette entrée. Je suis très content du produit, simple d'utilisation, avec un bon rendu si on le paramètre correctement par rapport à la cellule, Franck m'a conseillé pour ce réglage de choisir High level. L'envoi a été rapide et soigné. Merci maplatine.com

Fait superbement ce qu'on lui demande

Pour l'instant testé sur un de mes setups vinyles : Sansui AU 555A, Cabasse MT31 Microseiki MR611 et Hana S.

La mise en oeuvre est simplisme, connexion du câble de la platine (audioquest Wildcat) au bornes d'entré de ce step up ainsi que du fill de masse . Connexion des bornes de sorties à l'entrée phono (mm) #1 de mon sansui avec un Oelbach NF14, et roule...

La musicalité fait réellement un bon pa rapport au phono BOX DS2 que j'utilisais avec cette cellule un peu compliquée à associer avec son impédance élevée (1000 ohms pour en tirer la quintessence) ; là en mettant le sélecteur de l'aurorasound su "MID", on satisfait les 30 Ohms de charge interne de cette cellule...
Le résultat est que tout est plus naturel, sans aucun tassement dynamique avec une scène sonore qui se répand davantage dans ses dimensions.
Les détails sont effectivement plus nombreux et les timbres très réalistes. Un gros point positif est la matière que l'on gagne avec une belle extension du grave (malgré les enceintes de cette config qui sont limitées)..

Pour moi, c'est un magnifique moyen de donner accès aux cellules MC à ces amplis vintage qui ont d'excellentes entrées MM (après recapage dans les règles de l'art pour un ampli qui a 51 ans).
