    • A superb digital amplifier if you respect its very real limitations.
The Fosi TDA7498E is an improvement on previous Tripath-chip-style amps. It outputs more power, sounds cleaner, and has excellent clarity and rhythm - if you respect its limitations and use it with the right ancillary gear - by which I mean very sensitive speakers. This is my 4th Class-D "tripath-style" amp and each one has been better than the last. The whole concept is that a Texas instrument chip converts the signal to a gain stage directly on the silicone and the chip itself drives your speakers. There is very little additional circuitry and that's the key to its great sound, and also it's limited power. As others here have rightly pointed out, this ships with a 24 volt switching style power supply. The amp itself has what looks like 20-25 watts worth of capacitance. This isn't a 160 wpc amplifier. Fosi doesn't support that specification and it's probably derived from some kind of BS "instantanous" (i.e. transient) power delivery stat based on something theoretical. The real usable power - in my experience in room - is about 20-25 wpc with a 1% thd ceiling (guestimated using listening). I'm a 55 year old long time audiophile and I know what distoration sounds like. The Fosi TDA7498E is a tiny amp. Its binding posts can only handle slender flexible speaker cable. It has limitations driving speakers with sensitivies lower than 87-88 db/watt to satisfying volume levels and I'll describe exactly how I found that out - but the TLDR is that used with a high quality source and with efficient speakers I'm able to get really satisfying audiophile sound of them which makes them a stone cold audiophile bargain. I'm using the Fosi TDA7498E in a near field application with Athena AS-B1.2 speakers (which have a 90db/watt sensitivity). My source is generally a Windows10 pc running Qobuz and local FLAC rips feeding an ancient PS Audio Ultralink or Muse Model 2 DAC via a Musical Fidelity V-Link. I've used it with a Topping D70 (which is slightly less musical, but can play high-res). I initially used Straghtwire Maestro speaker cable, but was so inflexible that it damaged the binding posts on my first TDA7498E. Since then I've used used thin flexible wire (Audioquest type 2.1). When my new, unbroken second Fosi TDA7498E arrived, I had just received a pair of KEF LS-50s and was trying to drive them with an old AudioResearch tube amplifier and was having trouble getting good sound. I was awaiting delivery of used 50 wpc audiophile amp (the overlooked and thus low-priced April Audio Stello S100) - but it was delayed in delivery. I plugged the Fosi TDA7498E into the LS-50s in the living room and they meaningfully improved the sound on the ailing tube amp. But their grip on the LS-50s wasn't musically satisfying ultimately. The LS-50s are inefficient (85 db/watt) and low impedance (dips to 3.8 ohm) speakers and they ran the little Fosi TDA7498E into distortion before satisfying living-room listening levels were achieved. This doesn't jibe at all with the Fosi's claimed 160wpc 2-8ohm specs. More confirmation came a week later when the April Audio Stello S100 came and, despite it's modest 50wpc power rating, blew the doors off the little Fosi TDA7498E with the LS50s. It's a $1200 amp ($400 used), so it's not surprising that it handily beat a $75 integrated amp. But the reason it beat the Fosi was power. The TDA7498E ran out of gas and began distorting well before the Stello with the LS50. If you attempt to treat the Fosi TDA7498E like an ordinary amp with the specs it claims you will be disappointed. I also used the TDA7498E with Creek Audio Epos and ProAc Response 2.2s speakers and it lacks adequate power to drive any of them to really satisfying levels either. But, I cannot emphasize this enough - used with the 90db/watt high efficiency speakers it DOES have enough power to fill the room and do it with brilliant clarity, great bass, and excellent musicality. They are dead quiet in operation. With the source muted you can turn the volume all the way up and no audible hiss is detected at the sensitive speakers within 6 inches. You can hear that as a dead black background. The dominant sonic attribute I treasure with the Fosi TDA7498E is speed. Really good startle or "jump" factor. Not only is this amazing at the price - it's also performance that's clearly superior to earlier, lower powered, d-class tripath-style chip amps. This level of performance is incredible, IMHO and makes it a natural for shoe-string audiophiles. To sum up: 1) Buy the Fosi TDA7498E if you have a small room or a nearfield application and speaker with efficiency of 88db/watt or more. I'm guessing that 88db/watt is ok. I was only ever satisfied with 90db/watt speakers (the super cheap Athena SB-1.2 which were $150/pair back in the early 2000s). 2) Make sure you use slender and flexible speaker cable. They are so good for the price I am thinking of buying a second one and using them with RCA cable y-adapater splitters to try running them as bridged monoblocks (not a supported configuration and could well blow them up). If that doubles the effective 20wpc to 40wpc it might be enough to drive the LS50s, barely. In the meantime, it's the heart of my computer workstation nearfield listening which is, truth be told, my primary listening venue. This tiny integrated amp is excellent in that context. ... show more

    • Fosi replaced my defective amplifier with their apologies for any inconvenience.
I hope you don't ever have trouble with this amplifier because it's almost impossible to get a replacement during the warranty period. Fosi's technical offered to send a new circuit board meaning I need to fix their defective product. Advice Got a new amplifier and it works great.

    • Nice Amp, paired it with a airplay device.
Good sound quality, pretty loud with the speakers I'm using. Thinking of buying another.

    • A good value, but this is not a high-fidelity amplifier!!!
When I saw the extremely low price of this unit, I decided to buy it for fun, and just to have one more amplifier laying around. Never know when that might come in handy. I compared this to my Class-D Nord dual mono Hypex NCore as well as my Denon receiver using a pair of KEF Q350s in my treated listening room. To be absolutely fair, both of those devices are well over 10x the price of this unit. For DAC duties, I used my Lynx Hilo mastering converter. Driving a $70 amp with a $2700 DAC seems completely absurd, yet here we are. I wanted to be sure and give this little amp the best chance. I have a lot of gripes. I started out with Rai Thistlethwayte's "Go Nuts," a song with a lot of dynamics and production value. The piano in the intro comes across through this amp with a bit of abrasion. The high hats which I know set very nicely in this mix come across as harsh and trill. The stereo image is significantly blurred, causing the song to lose most of its magic. This tune has a nice, punchy kick drum, but both the bass line and the kick drum come across as anemic and lacking authority. Second up, I put on LeBrock's "Rush," one of my favorite tunes of recent memory. The intro to this tune, in a properly treated room with well-time-aligned drivers, is magical. During the intro, the speakers should disappear and the small percussive elements will dance around the room, floating in space, invading your ear-balls. It's one of the first songs I play when someone comes over to listen in my room. This amp completely butchered it... the smearing of the stereo image (perhaps due to crosstalk) really kills the effect. There's fog of some combination of harmonic distortion and IMD across the entire frequency spectrum. At this point, I had had enough, so I moved the connections back over to my Nord. It was like a shot of lidocaine during a toothache. "Rush" came back to life. The use case for this amplifier is something like a garage or workshop system, or driving some outdoor speakers on your deck or patio.... background music applications. Maybe, MAYBE driving height speakers in a basic Atmos setup. This amp is definitely not up to snuff for critical listening, and no one should expect it to be. I mean, it's $70! The fact that sounds come out of it at all justifies the price, which is why it gets a 3-star review. It's slightly more than $70 worth of amp for $70, but don't expect it to compete with the amps in basic powered monitors, let alone big-boy amplifiers. It will go back into the box and sit in my closet until I need a tiny amp for background music on my deck. ... show more

    • Perfection in Audio
I love this amp. Sounds better than my Denon integrated. I don’t know how Fosi does it? Maybe it will crap out in a year but guess what, I’ll buy another one. The only issue with this masterpiece is a very slight grounding noise when adjusting the volume. This is because Fosi has installed a metal volume knob and it’s not grounded 100% on the main board. To eliminate the slight static sound, connect a ground wire to one of the back allen screws on the unit and ground to the center plate screw on any plug outlet. Noise gone. ... show more
