Fosi Audio ZA3 Balanced Stereo Amplifier Home Audio Component Mini 2 Channel Mono Amp TPA3255 for Subwoofer Desktop Home Theater Bookshelf Tower Floorstanding Passive Speakers with 48V Power Supply

where to begin! My previous setup was Marantz PM6007 with WiiM Ultra & Elipson Planet L Speakers. I was ok with the setup but I knew, was missing something on the higher frequencies & details. just heard about this product on youtube channel "VirtualHiFi" - found many good videos with sound test comparing with 10k - 15k USD costing amps. I took the decision & bought this today with 48V power supply & right now its been playing for 3 hours replacing the marantz PM6007 only with rest of the same setup. I have no words to say - Man! it's blown away the marantz right out of the box and my elipson planet L speakers have come to life. it's a night & day difference. I kept the volume at 75% position & controlling the volume from wiim ultra and it's running cooler now than at 100% position. i am seriously thinking about the reason why it is sounding great than the marantz. Hmm.. may be one reason - the frequency range with 0.1+-DB? I don't know but it's sounding fuller, detailed, airy high-frequencies & analogue kind of texture. ZA3 changed my mind to join in the class D era as I have ordered another now to try as Monoblocks. I am totally happy & the value for money is top of the roof! I really appreciate the FOSI TEAM behind this to design such a great product! Best of luck for your next musical invention!!! Got the second one & set them as monoblocks - sound stage is wider now & details are more cleaner especially the vocals & mid range. I started enjoying my setup now with peace of mind!

Excellent Sound Quality and compact size with good thermal management. Blindly can go for it. Im using it in 5.2 home theater system.

Good preamplifier

Okay Good but treble over best only smsl suv1 bluetooth super

Great sound

Good

Class D is the new normal in audio amplifiers. Output is great. It has enough juice to drive my fyne audio towers. Power supply is bulky, though I feel an LPS or GaN power supply will boost the quality more.

Does not have crisp audio as TPA3116 , but does have bass and flat neutral sound . Watts per channel is good but of no point if your audio is not crisp. I have AIYIMA TPA3116d2 , 2.1(costed around 3k (amp board)) setup which performs far better than this 14k amp. I dont know why they call it audiophiles choice even though the audio is not that clear. I have added 1 video for the same comparison . one with
