Any decent class AB amp will hit or get within 10% of their specs, and or even sometimes exceed them. All of the exciting musicality you hear with other amps, even budget Class A/B models like I mentioned above, simply isn’t present in this budget Class D amp.

The BT20A Pro includes treble and bass controlswith a central detent so they can easily be reset to the neutral position. The tests are in 48 volt unless I say otherwise (I had mistakenly assumed it was the standard, not the 32 volt). After the pleasant surprise of the TB10D amplifier there was no question we would pass up a chance to review another model. If you do not have a lot of space for a traditional stereo set up, the Fosi is easy to squeeze into a tight spot. You have phono plugs for your input and banana plugs for the output, but for the output you could just have bare wire without plugs.This probably comes from my love of vintage audio pieces like my Marantz 2270 and my McIntosh MC 2505, both of which I have reviewed on this blog. Some may say that attracting looks is just a cover for lack of inner power, but by no means shall you be fooled by that as that hat has tricks in it. It will fit in just about any space you have available and the combined weight of the power brick and amp is still light enough you could carry this with you.

Most goods are not subject to import taxes when shipped from warehouses in the United States, the European Union, or Russia to their respective countries. My upstairs neighbour, also featured in the previous review, now prefers to check the levels of his music on the Fosi as opposed to the monitors and professional amp he has upstairs. Whether you’re immersing yourself in music, enjoying a movie night, or gaming, this amplifier consistently reproduces sound with depth, clarity, and accuracy.

To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. The original amp audio chip was a TPA3116, and the BT20A Pro has been upgraded to a TPA3255 amp chip. Given its sound quality and feature set, the Fosi BT20A Pro provides an excellent starting place for a beginning audiophile’s journey or as a replacement for an old, low-power receiver. The Fosi Audio BT20A is versatile and very configurable, allowing you to create your own system combination such as external DAC > external 4-band tone control > headphone amplifier > Fosi Audio BT20A. In addition to the separation improvements, the audio picked up nuances the original amp did not and the overall sound was fuller.

In my opinion, in this budget class, considering the level of build quality it offers, this Fosi Audio BT20A Pro amplifier is an absolute winner. I run this at about 3/4 volume which gives me great volume control from my TV, still leaving a little room should I want a little more max volume. It’s a little thing, but given that I have such a preference for the gray over the orange my review unit was equipped with, it’s obvious that little aesthetic things like this matter.Talking about the looks we must say that this unit has way too many light indictors of different colors. Fosi Audio BT30A gives 50 watts per channel, which is pretty good for a small unit like that plus a 100 watt for a subwoofer channel. I wasn’t completely surprised, however; I’ve owned and used a pair of Fosi TDA7498E power amps for several years and I’ve used them often with two-way monitors that had provisions for bi-wiring (two sets of connection posts, one for the tweeter and one for the woofer) with one amplifier driving the right and the other driving the left loudspeaker, I used each stereo amplifier as a monoblock. In contrast, the Pro was more balanced and laid back which made each song sound more at home in the mix. This system gave me all the capabilities of a complete Roon system, including upsampling and PEQ if needed.
