Review: A good choice, good value Class D stereo amplifier - If you are considering purchasing a stereo Class D amplifier and you don't require Bluetooth, digital inputs or balanced inputs then the Fosi Audio TB10D is a great choice. The TB10D stereo amplifier, when paired with a small music streaming device such as one of the WiiM music streamers (also available on desertcart), becomes half of a shoebox sized streaming audio system. You would just need to add a pair of passive (non-amplified) speakers. The bass frequency response of the TB10D was noticeably absent when first powered on. After about a half hour of operation the bass finally showed up and all was good. I leave the TB10D powered on as the standby power draw is very low. [Update: I measured the standby power consumption of the TB10D. Plugged in, not switched on, 1.0 Watt. Switched on, no input signal, power consumption is 2.5 Watts.] Even though I know that the location of the bass and treble tone controls on the TB10D are reversed, as compared with most other amplifiers and receivers with the treble control being on the left and the bass control on the right, I routinely forget and grab the wrong tone control. The speaker binding posts are small and close together. This is not an issue as I use banana plugs when connecting the speaker wires to the TB10D. Note that there is no headphone connection on the TB10D for wired headphones. If you need a small, inexpensive good sounding headphone amplifier for wired headphones consider the Fosi Audio P2 headphone amplifier. The TB10D's available output power, ~50 Watts per channel when used with 8 ohm speakers, with the included 32V/5A power brick is adequate for use in my kitchen audio system. The case and power supply of the TB10D remained cool to the touch even after extended listening (I measured 72F). If you have a large room, lower efficiency speakers, or desire audio levels exceeding ~85dB you should consider a more powerful amplifier. You can change the supplied external power supply for one rated for 48V, however this will increase the overall cost as well as increase the operating temperature of the TB10D. Within its limitations as far as output power, input options (one pair of RCA connections, no digital inputs, no balanced inputs), outputs (one pair of stereo speakers), no Mono mode switch, no BT, no Sub out, no headphone connection or remote control, the Fosi Audio TB10D is a very good choice. I found the sound of the TB10D when powering 4 ohm, 6 ohm and 8 ohm speakers to be consistently smooth, full sounding and non-fatiguing with a variety of music even after prolonged listening. I assembled a complete 2-channel audio system of exceptional value that can fit in a shoe box. Each of these products is currently available on desertcart. I chose the Fosi Audio TB10D amplifier that is the subject of this review. I added the well reviewed, amazingly compact WiiM Mini music streamer. [Update: I chose a pair of Saiyin Passive Bookshelf Speakers, 2-Way Passive Speakers, 3.5" Woofer & Silk Horn Tweeter that are sold on desertcart. I can't say enough good things about this small desktop speaker; see my separate review of the Saiyin DS6700M speakers.] This system is capable of filling almost any size room in a home with great sounding music. The TB10D amplifier's tone controls and the WiiM Home app's equalizer settings can be used to adjust the bass/midrange/treble output of the speakers.
Review: Works great so far. - Saw a review of this updated amplifier and decided to buy it so that I can take a vintage Kenwood receiver out of service to see about replacing capacitors in the unit's power supply and output stages. Got it with the standard 32 volt power brick. For testing hooked it up to a pair of older Infinity 8 ohm bookshelf speakers and an older Sony DVD player for CD playback. Plenty of power output, no background noise with the volume turned up and no signal. 6-1/2" woofers supplied plenty of bass with this amp in a small room and the volume and tone controls were fine, apparently fixed what people were complaining about in the previous model. Played for about an hour at a very satisfying volume level (RUSH, Working Men CD) and the unit didn't even get warm during use. This Class D amp is acceptable to me, no noticeable harshness in the sound. Very basic amp and very compact, seems to be great for a starter music system, you'll need a source like a DAC and a Wiim or turntable that has it's own preamp, The Infinitys I had bought used $60 and the Sony DVD for like $10 at a thrift store, so for around $150 it was a basic sound system that sounded pretty good. You don't have break the bank.

### ⭐⭐⭐⭐ Good powerful little audio amp … does what it says … mostly
*by T***M on June 5, 2024*

This is a great compact little stereo amp. It’s well built with simple front panel controls comprising a power switch, Volume, Bass & Treble controls. Back panel has stereo RCA inputs, combo screw and banana type outputs for speaker wires and an input for the included external power supply which could be either 32v or 48v depending on whichever option picked when ordering. Sound wise it’s subjectively quite good on the usual music program material into my JR149 speakers and sub. A little background hiss but nothing really annoying. So far operating well at normal indoor listening volumes ie: plenty loud enough. Now a little technical stuff. This is a Class D amp with differential speaker outputs. That means for normal operation each speaker pair must be completely isolated. Also the black negative terminals cannot be connected together or grounded under any circumstances. Doing so will destroy the amp. Bridging the left and right outputs for more power cannot be done either. Next can this amp could actually deliver 115W into 8 ohm or 230W into 4 ohm per channel as advertised. Using an sig gen at 1Khz, output resistive loads of 8 and then 4 ohms into a differentially connect scope I was able to observe over 100v peak to peak in each case just before clipping. Great I thought, 100W and 200W RMS as advertised ! However after about 4 seconds in each case, the amp thermal protection cut in and turned the amp off. Fortunately disconnecting the power supply and letting the amp cool down restored normal operation. While doing the power tests I noticed that there was a lot of high frequency switching noise due to the Sigma/Delta PDM operation of the Class D amp. This was mainly above 20KHz so mostly inaudible but did account for the low level hiss I noticed earlier. In conclusion therefore a great value little amplifier with plenty of headroom for loud music passages. As most modern music has peaks of about 10dB above mean level, using 4 ohm speakers and the 48v PSU will allow listening to program material at 20W mean power per channel without clipping distortion. This is really very loud clean music for most venues. However cranking the volume so that all the program material clips at 200W per channel and distorts heavily will just cause the amp to shut down temporarily, much to the relief for your guests and neighbors. Operated sensibly, this amp should provide many years of listening pleasure. Recommended !
