Very good with a flaw

A really big problem was not knowing that I needed a DAC so would work on my PC that is why I had so many returns and finally went to to Ayima and bought a A07 Max and a A2 DAC from them also

Perfect!

An inexpensive amp for my small room that does one thing very well. The standard 32v power supply is more than enough in my 9x10 room with Micca RB42 speakers. The volume control rarely needs to hit 11:00 o’clock.

An amazing piece of kit

I bought the V3 for my study and use it with a Wiim Streamer and a dedicated DAC. As speakers I use B&W 602.
This little amp exceeded my expectations. Sound is warm, full and rich. The detailed presentation lacks just ... nothing. Bass is good, the mids and highs are fine. The sound stage is present. All instruments have their place. I could not ask for more. Much better than the huge Denon AV Receiver, I used in the study before.

5 years ago I would have never bought an amp with only one input. But times are changing. Today i stream 100% of my music from the cloud. I use a Wiim Streamer to stream to this little amp. The times are over where you did have large stacks of hifi sources.

Great little amp

The V3 300 watt 2-ch amp does exactly what it’s supposed to do. And it’s simple and small and looks terrific.

Verdaderamente impresionante.

Es el amplificador ideal para espacios reducidos. Su diseño sencillo y pulcro lo hace más atractivo, solo una perilla para encenderlo y manejar el volumen, un led azul indica que está encendido, en diseño dicen que menos es más, en este caso aplica perfecto.
Todos los materiales de gran calidad.
El sonido es un tema aparte, no deja de sorprender la claridad y la definición que se puede obtener, en mi caso lo tengo conectado a unos Beovox S45-2 y los maneja sin ningún problema. Totalmente recomendable.
