Mounted on 2 STA 9X blocks - Spendor S5e speakers - results beyond my expectations.
On the phono or CD stage, lots of detail, warmth, and control in the bass, with a wide and deep soundstage. I am very satisfied with this setup.

Monté sur 2 blocs STA 9X - enceintes spendor S5e -résultat au delà des mes attentes.
sur l'étage phono ou CD beaucoup de détails, de chaleur et de tenue dans les graves une image large et profonde. Je suis très satisfait de ce montage.

Two years have passed since I replaced my RB-06 with a Nuprime STA-9, and being so satisfied with the latter, I decided this time to "upgrade" my preamplification section by replacing the good old RC-06 with this PRA-9X, which is robust and has very nice finishes.

Then, from the DAC (Topping D90SE) to the amp, everything is fully balanced, allowing us to benefit from the DAC's maximum dynamic range, which doesn't behave the same way in RCA. You can hear it immediately, with better separation and a wider soundstage.

But for me, the real plus is the phono stage, which is superb. I removed my Black Cube Statement from the chain to compare, and with the various settings available under the device for MM cartridges, I gain in dynamics, the bass is much better controlled, and the spectrum is more balanced.

To conclude, I didn't witness a miracle, but rather a reasonable and reasoned upgrade in a system that was already quite coherent.

I don't really believe in the "burn-in" theory, but in any case, after a few days of use, we're not light-years away from the Rotel RC-06, but you can feel that we benefit from the latest technologies and Nuprime's expertise... the PRA-9X // STA-9 pair works wonderfully together.

A very good acquisition.

Deux années ont passé depuis le remplacement de mon RB-06 par un Nuprime STA-9 et tellement satisfait par ce dernier, j'ai cette fois-ci de "mettre à jour" ma section de préamplification en remplaçant le bon vieux RC-06 par ce PRA-9X, robuste et disposant de très belles finitions.

Ensuite, et depuis le DAC (Topping D90SE) jusqu'à l'ampli, on est en full symétrique, ce qui permet de bénéficier de la plage dynamique maximale du DAC, qui ne se comporte pas de la même manière en RCA. A l'oreille ça s'entend immédiatement, avec une meilleure séparation et un soundstage plus large.

Mais pour le moi le vrai plus, c'est l'étage phono qui est super. J'ai supprimé mon Black Cube Statement de la chaîne pour comparer, et avec les différents réglages disponibles sous l'appareil pour les cellules MM, je gagne en dynamique et le bas est bien mieux tenu et le spectre plus équilibré.

Pour conclure, je n'ai pas assisté à un miracle, mais plus à un upgrade raisonnable et raisonné dans un système plutôt qui était déjà plutôt cohérent.

Je ne crois pas tellement à la théorie sur le "rodage" mais en tout état de cause après quelques jours d'utilisation, on n'est pas à des années lumière du Rotel RC-06, mais on sent que l'on bénéficie des dernières technologies et du savoir-faire de Nuprime…le couple PRA-9X // STA-9 fonctionne à merveille ensemble.

Une très bonne acquisition.

After 3 weeks of use, I am very pleasantly surprised by this preamp, which in my opinion deserves a place in high-quality systems. Its affordable price does not reflect its qualities.
I intend to use it to drive active speakers wired with XLR cables in a secondary system, but I have also tested it in a classic configuration with a power amp. In both cases, it is a true pleasure.
It's worth noting that it needs a good fifty hours of break-in time, during which its sound changes several times.
It is also sensitive to the power cable that supplies it.
Finally, and this seems important for a preamp, the volume can be adjusted precisely step by step using the remote control.

Après 3 semaines de fonctionnement, je suis très agréablement surpris par ce préampli qui mérite à mon sens sa place dans des systèmes de bon niveau. Son prix contenu ne reflète pas ses qualités.
Je le destine à piloter des enceintes actives câblées en XLR dans un système secondaire, mais je l'ai aussi testé dans une configuration classique avec un bloc de puissance. Dans les deux cas, c'est un vrai plaisir..
À noter qu'iI lui faut une bonne cinquantaine d'heures pour se libérer durant lesquelles son rendu varie plusieurs fois.
Il est également sensible au câble secteur qui l'alimente.
Enfin, et c'est important pour un préampli me semble-t-il, le réglage du volume par la télécommande peut se faire pas à pas, donc avec précision.
