Now this is something completely new and surprising, punching above value TPA3255 implementations.
Balanced, dual mono setup (yes, shared power supply, but you can get two of them too).
Working in BTL mode with fully balanced internal configuration, XLR inputs and possibility for opamp rolling - this one has to join my amp collection :)

You can get yours from the same shop I got mine from (so tested as safe and reliable - and thats not always the case, but you do not get to see the reviews for the equipement that was damaged or lost on the way, obviously):

Dont make a mistake: this small, humble set is proper hifi!

Equipment used in testing:
Foobar - passive 11th gen Intel PCwih LPS - AQJitterbug - Chord USB - Singxer SU-6-IIS via fk AQ Thunderbird -Gustard X26 Pro and Semibreve DA50 (yes two DACs) - fk Dragon XLR - AMPLIFIER - fk Dragon/K2, Red Dawn - Dali ikon 1 mk2, Dali Opticon 1, ML 15i ML35XTi and ML Ascent I electrostat speakers.

------------
As there are questions in the comments, my recommendation for the preamp would be Cary SLP-90 clone:

or (same seller, has two shops)

And hinted by you guys, version with slightly larger and silver chassis:

New set of Aliexpres codes valid untill October 31st only.
I've chosen some popular devices that I recommend (like Cary clones or C2860+ preamp) and you can reach them via collection page:
https://s.click.aliexpress.com/e/_Ew8...

Ali portal says these codes should be valid almost everywhere in the world, with few exceptions, and for almost everything (minus mobile phones but thats the way it is)
$15-2: 【IFPPJWWL】 $35-5: 【IFPKVWAG】 $65-9: 【IFP9OI52】 $99-14: 【IFPHCJVG】
$169-23: 【IFP7421X】 279-40: 【IFPNXV5Z】 $379-55: 【IFPTBFPT】 $559-80: 【IFPPYCF4】

I also own the Zerozone TPS3255 and previously used high-quality Class-A technology. I also acquired a second power supply for the monoblocks to enhance the bass response and channel separation. After extensive testing, the monoblocks now use OPA828 op-amps with an additional decoupling operational amplifier base. These perfectly complement the Burson V7 Vivid and OPA1656 op-amps (made in France) in my DA50Pro Semibreve DAC, which are also optimized with a decoupling operational amplifier base. A Chinese clone of the Mark Levinson JC2 with modified Mundorf capacitors (mcap evo silver gold oil) serves as the preamplifier. Considering the financial investment, the sonic result is simply stunning.

Oi Vey!! My ZeroZone TPA3255 separate mono speaker amplifier set arrived (rather promptly) today. Coincidently, so did the 2 set of the Staccato OSH-DHb Discrete Opamps. Just as you said in the review, a truly remarkable amp set and opamp upgrade!! I played the set out of the box for quite a while. I was impressed immediately. Then I swapped out the opamps! What a HUGE Difference! - Made me laugh out loud when I first fired them up. Really opened up the sound stage breadth, depth, detail and added a lot of appropriate richness to the sound. You are so right. Live music sounds spectacular - decays & all. What a huge Bang for the Buck overall. Amazing.
I have done the same on the Aiyima A07 and a pair of the Fosi Audio ZA3s including upgrading the opamps with Sparkos SS3602 Discrete Duals. I am really appreciating the Class A sound.
I can only imagine the improvements a couple of hundred hours of break-in time will do. This already sounds better than the ZA3s (yes, the A/B'ing has already started).
I encourage you to revisit this with another video assuming you upgrade the components esp. the Caps. Would love to hear how that goes. Well Done!!
BTW - Your videos started me down the clone amp (Accuphase E406) & preamp (Accuphase C245) rabbit hole also. Very dangerous! Yes. It is all your fault! :)

I am loving these monoblocks, the way they interact well with my Preamplifier is just great, every little nuances in the recording keeps coming out in such a nice way.

Thank you for a very good video

@De132an 1 year ago

Wonderful information. Your videos are invaluable for those looking to get good quality performance at more affordable pricing. Not everyone can spend $$$ on audio systems.

@edverbeek6292 2 years ago (edited)

Thank you very much. I liked especially the comparison with opamps and other gear.
Zerozone offers also the bare components (pcb boards), 57 euro each, so i will go DIY with these; Incredible value for the money.
Thanks.

Hi Mr Hi-fi Zone, i have watched so many of your reviews, really first class information you provide to the audio community, you deserve a commendation! My simple question, if i may, would you recommend the Zero Zone TPA amps, or the Dartzeel clone as your first choice at this point. Thanks so much

I do like these little mono blocks are on my next to buy list

@nicholaskaethner2584 1 year ago

Thanks, i love your videos and will soon be buying this 3255 amp based on your excellent review...😅

@FrankZappa1959 2 years ago

The pricerange is sensationell!! Look at similar Class D Power Amps from the best,but most underrated Brands like BOXEM AUDIO, AUDIOPHONICS, XTZ etc. - not mentioned the "Ultra stuff" like Jeff Rowland Audio Group (JRAG) - from the price prospective this offer is A HAMMER!!

After watching this over and over I have finally pulled the trigger on these amps they take a while to reach me here at my home on st Helena but I will let you know
