Default Boyoho and Formosa Audiomate

Anyone familiar with these brands?

Boyoho are seen in C-mark amplifiers, and looks interesting with good specs.

Formosa are used in SVS subwoofers, and have an interesting range of amplifiers with DSP.

I have seen Boyoho in a dutch webshop, but can't find it again -* anyone who can point me to that?

Anyone knows other products that use formosa?

thanks. That's the one. But quite pricey i think. The modules are used in cheap budget PA amps, and I actually thinks it just as cheap just buying a c-mark amp or a class d t.amp from Thomann

Dear all,

These Boyoho amps are not used in budget amps!, please open up a budget class-d amp you will find something totally differend than the Boyoho amps.

these are quality amps with full datasheets, and a very good sound.

only downside I can think of is the low imput impendance of 4,7k

but this is easilly altered with a pre-amp.

I don't doubt that. But they are still used in c-mark amplifiers. I also read somewhere that Thoman used these, but I also found another chinese maufacture K something sorry I just forgot the brand.

looking at these amps the powersupply looks very weak, especially if you want to get these high power outputs. That is what I mean if you open up cheap amplifiers, the powersupply part is where they save money on. if you try to drive a large sub you will get in trouble.

Your not the first to see the week power supply in Kobble. I'm not into thousands of watt, just decent 200 watt 8 ohm distortion below 0,01% (also 5-7 khz)

Glad to hear that Boyoho looks to be better quality. I'm also looking at Formosa audiomate (used in SVS subwoofers) since they also have interesting DSP options.

Customer test says it all!

Quote "Nach kleineren Kabelmodifikationen (bessere Schirmung) und einer beträchtlichen Einspielzeit hat der Hulk klanglich zu den Anaview Modulen aufgeschlossen. Die Härte im Sound ist so gut wie komplett weg. Wir haben den Hulk in einer Hörsession der Wiener DIY Community ausgiebig getestet. Seine Spielpartner waren: Duetta, Big Needle und Little Princess und an allen Lautsprechern konnte er voll überzeugen. Die Lässigkeit und Selbstverständlichkeit mit der der Hulk zu Werke geht ist wirklich beeindruckend!" Source
