Here is new additional from O-Noorus............... O-NOORUS D4 PRO TPA3255 PFFB stereo HPF LPF Amplifier with Balance HDMI ARC Bluetooth USB Optical Coaxial RCA input, 3-Band stereo EQ tone and bypass...

Hi Amigoes We are preparing to build a multi-channel amp. Wanna know which model is more popular for users? If you are interested, please help us get your vote. Leverage A5(TPA3251),A7(TPA3255) PFFB design with built-in GaN Power supply Pure-Amplifier without volume control, configurable...

You can delete )))

SMSL also jumps onto TPA3255 amp space now, quite a package of features in this small unit: Note- They haven’t mentioned PFFB, so it’s unclear but possibly not deployed. Frequency response graphs aren’t available as well.

Hi amigos It would appear that Wiim has launched their brand new WIIM CI MOD A80 Network amplifier based on a TPA3255 / ESS ES9018K2M chip. I'm not convinced it's a revolution compared to the Wiim Amp Pro and Ultra, but this new Wiim is available on Audiophonics...

Hi Amigos, To my great surprise, I received a sample of the Onoorus D3 Pro this morning. BTW a BIG thanks to @Alexander Lin for keeping his promise ) I'll take the time to test it next week to compare it to my Wiim Amp Pro. In the meantime, here's a teardown of the D3 Pro with a procedure for...

Aiyima posted this on their fb, new balanced amplifier A20. Looks simple design (looks) like P7, PA7 etc., launching this week. Most likely tpa3255 balanced amplifier. @AIYIMA Congrats and All the best for new products.

This gentleman ‘Guntars Smits’ reads TI PFFB implementation document and describes its too complicated and mostly not really needed unless application demands like running horn tweeters. Is he making any sense?

Hello together, I know the title sounds a bit cynical, but I'm wondering this myself. If there is already a similar thread, please move mine there. There are now some very good Class-D amplifiers based on the TI TPA3255 chip. The best (according to Amir's measurements) currently seems to be...

This is a review and detailed measurements of the O-NOORUS D4 stereo integrated amplifier. It was sent to me by the company and costs US$139 from them direct with the 48V/5A power brick. It is fundamentally a small box TPA3255 design with PFFB to give a flat response into any load, but it has...

Dear FMs, ..........This is "User Impressions, Observations and Owner's Thread" for Arylic A100 Streamer Amplifier.......... In continuation with my interest in TPA3255 amplifiers, I came across Arylic A100 which uses TPA3255 with internal power supply. It uses linear power supply than...

What are the issues in using linear power supply (transformer + bridge rectifier assembly etc.) with class D amplifiers? Idle energy loss too high? Efficiency? Magnetic field interferences? Price? Almost every established traditional brand (like Denon, Marantz, etc.) used linear PSU in their...

Dear FMs, This is "User Impressions, Observations and Owners Thread" for O-Noorus D4 Amplifier (or Stereo Receiver, as has ESS 9023P based DAC as well). While we await if and when D4 get's measured on ASR, this thread hopefully will capture available details, features, internal pics, quick...

Hi amigos, It seems that O-NOORUS has made the answer to the new Aiyima A80 )) The O-Noorus D4 comes with some OPA1642 op amps and PFFB inside Price : $119 At this price, I think it will be very promising. On the other hand, I have doubts about the announced performances given its PFFB...

If you take the different power output options (through internal or external PSUs) off the table, do the current Class D chip amps measure up to a Hypex Ncore? Will a TPA3255+PFFB sound the same top-to-bottom as a NC252MP at 2 watts with a 4-ohm speaker? Or is there still something...

Dear FMs, Douk Audio posted a thread about this A100 amplifier HERE sometime back and they shared loads of information with internal pics, measurements like SINAD and power output. I have recently got Douk Audio A100 amplifier, as I continue with my enthusiasm to explore TPA3255 chip...

[Aiyima Decoder Amplifier - TPA3255 based amplifier with ES9018K2M DAC and NJW1194 based volume/tone controls] Dear FMs, This thread will capture Aiyima Decoder Amplifier - User Impressions | Owner's feeblack. I mean to summarize: > what I get as a buyer or user of Aiyima Decoder Amplifier >...

I had the intention of building my own stereo amplifier and ordered parts to built a TPA3255-based amp based on the Micro Bamboo project by @daniboun. https://www.audiosciencereview.com/forum/index.php?threads/3e-audio-tpa3255-260-2-29a-amplifier-review.50208/ However, I was too lazy and...

After having my latest board I took a chance on die a sudden abrupt death. It was a dual chip TP3255 based board from China, the Samp-200. The board had a lot of promise and sounded fantastic till it blew up one chip through no fault of my own. I decided to try another board that been getting...

Hi Amigos: It has been for around 2 years after we release TPA3251 and TPA3255 series amplifier DIY kits with post filter feedback design that improve the overall performance of the single chip itself. With many buyers(diyer) enjoyed our diy kits and having so many fun from their own diy...
