Review: Amazing well priced little device with outstanding power - Overall its quite good actually. Looks sure need improvement as silver bolts with dual rotation dial infront doesn't look elegant. Power:- it handles quite a big watt number range(220w max) but do remember the power supply in box is only upto 100w so to reach that max you need to buy new power supply so extra spending there. Still for 100w, i just listen at 30% volume as its that powerful. I have connected it with Bia Acoustics 8" Sub and just at that volume it sounds elegant and pleasing with enormous deep bass. I really like it. For medium size room just that much power is enough so think what would a full volume cover let alone 220w psu. So overall its amazing little device. Ports:- Has 2 way binding posts(banana plugs/bare wire) at back, i am using bare wire 2.5 sqmm(around 12-14 awg) to connect it directly to my sub as i don't like extra hanging wire and didn't want to cut my expensive ofc cable from dhivis. And that wire just barely went in so do remember that. Freq Range:- do note that TP-02 covers 20-120hz range shown on fosi webpage but desertcart webpage shows 20-200hz. I confirmed with fosi team about this and they said unit as a whole covers 20-120hz but freq dial infront covers 20-200hz. Well thats confusing now. Would have been nice if freq dial had numeric markings on it. Comparison:- so comparing it with plate amps i would say its versatility and simplicity to just drag and drop, plus connect to any sub just makes it better option over plate amps. Also it doesn't lack in any way compared to AB sub plate amps. There is no noise at all when idle and sounds amazing. Plus consumes less power than class AB amps so its better for environment and budget. I checked with smart plug and it showed 20w while playing so good, if measured wrong then still it won't be much more than 30w as class D amps are power efficient devices so they are gaining more popularity now while still covering beautiful audio quality provided by AB amps. Also its cheaper in price also as recently it hit ₹5699 price mark. So save it cart to catch that deal when it comes back around.
Review: Purchase it if you need to improve - Superb product and more power than it’s specification
