TOPPING PA7 Amplifier Class D Balanced 2x200W 4 Ohm Black

TOPPING PA7 Amplifier Class D Balanced 2x200W 4 Ohm Black
The Topping PA7 is a powerful amplifier, based on a Class D architecture and benefiting from an intelligent and particularly careful design. It is thus capable of developing a significant power while maintaining a very low level of distortion. The technologies used ensure a clear, precise and deep sound reproduction. In addition, the balanced structure of the PA7 provides effective transmission noise reduction.

Incredibly low distortion level

The PA7's performance in terms of distortion is close to that of a very good DAC. It always remains extremely low before clipping, ensuring a constant reproduction quality whatever the volume level.

Impressive power

The PA7, despite its compactness, is capable of delivering a significant power. It will indeed be able to deliver no less than 2x200W under 4Ω (1% THD+N) or 2x125W under 8Ω (1% THD+N). It is thus capable of powering greedy audio systems without difficulty while offering a beautiful dynamic.

Single-ended & balanced outputs

The Topping PA7 provides a double input connector. There is an XLR / Jack 6.35mm TRS combo for balanced transmission and a stereo RCA input for single-ended transmission.

Volume bypass

The Topping amplifier has a volume control. It is however possible to bypass this control to use the PA7 as a power amplifier, by associating an external preamplifier (not supplied).

12V Trigger

Equipped with a 12V trigger input, the PA7 can be connected to other devices to take advantage of an automatic on/off function of the system set up.

Bonne impression lors des premières écoutes
J'ai changé mon Harman-Kardon HK670 pour ce modèle. N'ayant pas encore reçu les cables de modulation symétrique, mes premiers essais ont donc été en asymétrique. J'ai un sytème Daphile avec un DAC Topping DX7 Pro et des enceintes JM Lab-Focal 726 S. Le contraste avec mon ancien amplificateur est important : son plus doux et mélodieux, basses mieux définies, mediums moins criards et aigus montant plus hauts. Le PA7 est moins punchy que le HK mais répond très bien aux variations dynamiques des enregitrements. La spatialisation est magnifique. Je ne savais pas avant ce que donner un amplificateur audiophile mais, bien que n'étant pas mélomane j'ai vite perçu la différence avec mon ancien matériel. Je pensais que mes enceintes étaient le maillon limitant mais pas du tout, elles sont encore meilleures maintenant. Le PA7 est encore en rodage mais bientôt avec les cables symétriques ça devrait être encore mieux. La seule question que je me pose c'est celle du préampli : pour une qualité optimale, dois-je utiliser celui du PA7 ou mettre ce dernier en bypass et utiliser le préampli du DX7 Pro, ce qui me permet de régler le volume sonore avec la télécommande ? J'aimerai vraiment avoir une réponse de spécialiste à ce sujet et notamment d'AUDIOPHONICS. Pour le moment, j'ai l'impression qu'en bypassant le PA7 sa puissance à baisser et peut-être aussi sa dynamique.
