FX-AUDIO TUBE-03

Tubes preamplifier 6K4 Stereo Silver

fx-audio tube-03 préamplificateur à tubes

Introducing the all-new 6K4 FX-Audio TUBE-03 tube buffer preamplifier. The latter now offers bass and treble controls accessible from the front.

This TUBE-03 acts as a clever little tool to improve the sound of a desktop DAC or HiFi installation lacking punch. With a gold-plated stereo RCA stereo input and output, it will be a quality companion coupled with a class D power amplifier to restore dynamics and sound to any missing installation.

At the proposed price, this device has qualities usually absent in this category.

Moreover, this preamplifier does not have the caricatural sound impastoed in the lower midrange of classical tube productions. On the contrary, the terms transparency, dynamics, musical untiedness, sound matter are the ones that immediately come to mind.

An entry level excellence for any enthusiast who wants an affordable tube preamplifier of high quality.

Great little thing
This is actually the third Tube-03 I have purchased, have already written a little review about the black model. I simply like this preamp and what it is adding to my setups. I am using this little thing with the two DAC + headphone amp setups (Topping D50s/D70/A50). The third one is connected to the Fase Performance 3.5 audiophile grade integrated amplifier. And it really adds the warmth and feel of tube sound. Also like the possibility to change its opamps. With another set of opamps and tubes (OPA627+OPA1622+GE5654W), this preamp immediately jumped to another level. By switching back and forth between two outputs from the D70, one through this preamp and the other without, it becomes clear this preamp adds warmth and makes the sound more spatial, very pleasant to listen. Found in the box it actually comes with taller 6k4 tubes instead of the advertised 6J1. And they sound different. 6k4 are more meaty on the bass with darker sound, and 6j1 sound somewhat cleaner and brighter. I think they are both good enough to begin with. However, I suggest to replace the stock tubes with GE5654W or Voskhod 6J1P-EV. GE5654W will add deeper bass with more impact and make the sound very pleasant to listen for hours. Voskhod tubes are a bit lighter on the bass (still great), but they add quite a dose of holographic 3D sound + will emphasize a tons of details in the sound. Hope Audiophonics can add them to their catalog, maybe also some other EF95 tubes. Tone controls are also very useful. There is no buzzing, hissing or audible distortion even if you crank the volume, bass or treble up. One drawback on this silver model is that the position marks on the potentiometers are difficult to see because they are also silver so they blend with the background. Otherwise it feels robust and solid, PSU that came with this one is rated to 12V 1.66A, comes well packaged and sounds great. This is a great and really inexpensive way to add a tube sound to your system. Can't really think of anything that could make more positive effects to the sound for the price. I sincerely recommend. And Audiophonics was great as always. Well packaged, shipped quickly, great support...

Très satisfait
J'ai acheté ce préampli pour installer deux amplis Tripath Trends TA 10.2P en blocs mono chacun amplifiant son enceinte. Je ne voulais pas dépenser une grosse somme mais avoir un contrôle de volume et de tonalité.
C'est plutôt pas mal du tout. Pour le moment j'ai juste essayer avec mon baladeur Hi-Res.

FX-AUDIO TUBE-03 Préamplificateur à Tubes 6J1 Stéréo Argent
Petit appareil intéressant pour alimenter une petite installation. Amélioration possible en remplaçant les tubes : à tester dans ces conditions avec un amplificateur de puissance et des enceintes de bon rendement.

Petit bijoux qui est un must have !
Je l'ai acheté pour l'utiliser avec des enceintes de monitoring qui manquait un peu dans le bas du spectre.
Le réglage de basse se fais en douceur chaque incréments est sensible mais pas excessif donc parfait.
Le son maintenant..
En premier avec les tube d'origine:
Le son est très orienté sur les aigu clairement ! Sa fais un peu mal aux oreilles si écoute au dessus de 2 heures à FORT volume.
Mais par contre les instruments ont une bonne présence et c'est assez agréable
Pour des tubes dis bas de gamme sa sonnes bien..
Maintenant je les ai échangés avec des ge 5654w et là c'est au niveaux des voix que sa tape..
Plus mis en avant et d'une douceur..
Les basses et les aigus sont plutôt amortis et les médiums bien mis en avant mais par contre les morceaux de basses vont vous faire vibrer c'est un délice !
Donc j'ai envie de dire questions de goûts.
Les 6j1 sont bien
Les 5654w apporté une certaine douceur sur les aigus.

Pour finir je le recommande à 100%! Pour le prix que sa coûte vous serez étonné :D
