LiNKFOR TPA3221 Hi-Fi Digital Power Amplifier

[gasolin75]

Can this amplifier be recommended ? It's a tpa 3221 based amp and as you can see it has 4 inputs so you basically don't need an audio source selector if you have a tape deck,pc,cdplayer and a turntable (with either built in phonostage or a separate phonostage), in my case i just need a usb to digital out converter since my motherboard doesn't have an optical or coaxial out, i have one, i could then use a compact class d amp without a audio source selector

In the AIYIMA A05 Review (also a tpa3221 based amp) they say it't has high distortion at low levels https://www.audiosciencereview.com/forum/index.php?threads/aiyima-a05-review-budget-amplifier.26440/

Is it worth going for one ?

Without testing who knows? The TPA3221 datasheet should give you an idea of the upper limit of performance, but in a cheap amp there are probably going to be some compromises so it'll probably measure a bit worse like the A05 did. Another thing manufacturers often mess up in this product class is proper sequencing to avoid pops on power up and/or down. It's an interesting feature set at a low price, so could still be good value even if the performance isn't great in absolute terms.

No pop sounds from my fosi audio BT20A

I have a TPA3116 and a infineon 12070 amp both have to be used with an audio source selector so one less unit to use with an amp that has 4 inputs although i have to use an usb to coaxial or optical converter from my pc

Theres also the diffrence in the chip, once had a TDA7498E but wasn't as good as my fosi audio bt20a amp

I think this product uses TPA3116 instead of TPA3221 due to the power supply voltage and heatsink structure.
Maybe the output power is 50Wx2 instead of 100Wx2.
