Hi everyone, here a new at ASR as a user, but not as a reader. I am looking for objective advice on a planned upgrade path for my desktop HiFi system. Current Setup: Room: Small office (12m² / ~130 sq ft). Amp: Rega IO (30W @ 8Ω). Speakers: Martin Lab 38 (Sealed monitors, similar to vintage...

Hi amigos Just to share I found this new dual TPA3255 + PFFB. The price seems very attractive. Makes me think the 3E Audio A7 BTW. I wish Amir could test it. See attached files for details Main spec : PFFB Dual TPA3255 (seems to be a one chip per channel) Trigger Pre-out Upgradable Op Amps...

I am using the 6.35mm jack on the Fiio K11, not sure it has enough power to drive my new Audeze LCD 2C. Expected more bass as a Beyerdynamic user, mainly for neurofunk and dnb. Used to have Fosi GR40 for a while and really liked the BASS knob. Returned it out of laziness, did not want to change...

I was hoping for something like an alternative to the fine Neutron HiFi DAC V1 , just for eample. ...Or devices by Qudelix, E1DA, FiiO, or late FC5 by Hiby. - A dongle DAC with PEQ functionality written into EEPROM - "ready to go" on boot up - with no need of any Android "companion" apps or...

Hello! For some time I've wanted to try an external DAC but I currently have a WiiM Amp Ultra, where I can't use any external DAC. I also have a WiiM Ultra in the closet and I'm thinking to myself if it wouldn't be worth using it instead of Amp Ultra and buying a DAC R2R + pure power amp (V3...

I just received Fosi SK 01 and 02. Didn't know that they existed.. I have been searching for something like 01 to use my Sennheiser HD660S with my tape decks. Fosi, if you're listening, a variable loudness with 2 band PEQ for lows highs will be an excellent device. Back in 2021, I bought a...

Hey everyone, I recently upgraded to the Wharfedale EVO 5.4 speakers, and while I like what I hear, I’m not entirely convinced I’m getting the best out of them with my current setup. Right now I’m running them with a pair of Fosi V3 mono amps, and a WiiM Ultra as DAC/streamer. The Fosi V3s...

Looking at Fosi's new product lines and upcoming in production units I love that they are focusing on balanced units and more sub outs with high passes on more units. I might still buy the new ZP3 Pre amp but it seems big and excessive for a simple crossover for my studio monitor setup with svs...

Hello everyone, First of all, I'm not sure this should be under this category or noob questions, so sorry if it's misplaced. I'm a complete novice and have little knowledge but was using the test data and informative videos present on this site to try and improve my audio setup at home (mostly...

Hi everyone! I am new here but I already see there is plethora of useful information. About a year ago I created a setup for myself with goal of listening to vinyl but also being able to listen to digital audio (apple music, spotify etc.) Give this was my first setup I bought most of...

Sorry for the long-winded post but after hours of research I thought I’d just ask. I’m completely new to audio systems but have learned a bit and just wanted to get some expert opinions. I’m having a free-standing aluminum covered pergola built that will have wifi and power that is right next to...

Hi amigos, Before starting, I suspended the measurements of the first project "Micro Bamboo." I will come back to the quick measurements at the end of May finally, I still have to speak with Sami about his Micro Audio PSU... am focusing on this thread only on the measures of the "Bamboo V2"...

Hi, I have a Fosi Audio BT30D (non pro version) connected to a pair of 8 ohm 60-100w speakers. Input is RCA from desktop PC. I am happy with the audio quality and loudness. I have a small room so I drive it at 50% amp volume usually. The problem is that whenever there is no audio output the amp...

I have a Fosi BT20A pro that is measuring significantly lower voltage on one channel. With a 1kHz test tone, I’m seeing about 10v less on one channel. With a 60Hz tone, I’m seeing 24.2v on one channel and 1.3v on the other channel. I’m still fairly new to this, but given its worse with lower...

Fosi Audio recently sent me a fairly new product to try out, their N3 bluetooth receiver/headphone amp. It's a bit of a niche product but I was interested to review one after seeing the photos. It is currently available on "that auction site" for $60, but I don't see it yet on Fosi's main...

I’m new to anything audio. Seeking some guidance as to what is the role of this capacitor in the amp? Also, curious what was the likely cause. I was running the amp pretty hard at 48v when this occurred. I replaced the blown capacitor with an equivalent Nichicon cap. I am still not getting...

Firstly, I would like to say, this is my first Fosi Audio product. And so I would like to mention that the build quality and the sound is great, no clicks or pops, and no dreaded white noise whilst on standby. Especially at the price. I've definetly been swooned. Now my actual question is...

Hi dear. Good afternoon, I have been reading reviews about Chinese amplifiers from brands like aiyima, slms, fosi audio, apparently they are not very durable over time and there are some people who indicate that they do not have much security against overloads or that failures occur with one...
