Fosi Audio v1.0b

[dayronch]

Hello everyone does someone has this amplifier? I purchased one but didn´t receive it yet. I need more than30w per channel for a pair of Sanyo speakers that came with my MCD-Z300F mini component. The speakers are rated 30w@6ohm. I know I need a bit more than the power that's rated in the speaker because as preferred always to have a more powerful amplifier to feed the speakers at least 1.5x the power of the speaker to handle dynamics, but I needed to save money as well. In this I found a bargain and I hope it to be a good product as well. I don't call it a bargain as to some cheap product, otherwise I thank Fosi, for the excellent amplifiers they produce. I´ll be using mi Motu M2 as my preamplifier. So you tell me what you think about it.
Thank you, guys.

I´ll be posting some photos of my Fosi Audio V1.0B so if someone is interested in purchasing from the different retailers they know what's inside and how it performs

This is based on the old TPA3116 Class D chip and I doubt you'll get an honest 30+ WPC with a 19V power brick. I would suggest something based on the newer, more powerful TPA3255, like the fairly well regarded Aiyima A07, which has been around for several years. Here's Amir's review: AIYIMA A07 TPA3255 Review (Amplifier)

Thank you Bruce for your suggestion. It gives me a new idea.

Thank you Bruce for your suggestion. It gives me a new idea.

I don't know what your budget is, but would recommend either the Fosi V3 stereo, ZA3 stereo or V3 monos.

I have all of those and they are all great.

Thank you Brian, I will look forward to the Fosi Audio ZA3 model with 48v power supply, that will give plenty of headroom I believe and a future proof amplifier as well for new speaker if I decide to have another set. My budget is limited by now, I just feel curious about this mini amplifier and see how it performs, despite it looks so cool and compact, when I opened it was good to see the construction is not bad at all and notice the sane NE5532 Op Amps on them even when they are not removable. it surprised me to see that they are working very good in the pcbs even for this more affordable amplifier. The ZA3 is my goal in the coming months I will save some money for it, for the advised performance and design. I would like to know the damping factor of this particular amplifier, to have an idea of the control of the speaker when performing.

Fosi Audio ZA3 Amplifier Review

This is a review and detailed measurements of the Fosi Audio ZA3 stereo amplifier with balanced XLR inputs. It was sent to me by the company and costs US $149.99 with 48 volt power supply. The amplifier has really dressed up from its earlier origins of common enclosures in budget class...
