    Fosi Audio DS2 Portable DAC & Amp Review

    Balanced 4.4mm out to balanced TRS in on the miniDSP Flex balanced version sounds absolutely mint. I am using the USB-C splitter mentioned earlier to keep my phone charged at the same time it plays - I am actually using my phone as a mobile balanced source, at this dynamic range and low noise...

    Fosi Audio V3 Mono Amplifier Review

    I ended up returning all 4 of my V3 monos. I bought 2x 2 sets with 10 amp power supply. 1 of 4 amps died fairly quickly, although I was torture testing them beyond what any normal person would do (although the one that died was on lightest duty @ around 90 W into 8 Ohm continuous for many...

    Fosi Audio DS2 Portable DAC & Amp Review

    I did get the interrupt/fade in error people are talking about. BUT this was during an uninterrupted 90 min set - single file, no breaks. Happened 2-3 times consecutively (in 2 mins). I paused, started music. Didn't happen again for 30 mins now...... Edit: Win 11, Media Player, all updates...

    Fosi Audio DS2 Portable DAC & Amp Review

    Working amazing on Windows 11 playing studio rips of my favourite electronic artists (wav at 24 bit 48khz). Incredible to be honest. Simply the best audio I have ever heard. Edit: Just using Windows Media player. Device selected as main out in windows. Holy cursing angels this is a good...

    Fosi Audio DS2 Portable DAC & Amp Review

    I have always only gone with PCM/FLAC. At the extremes of these formats, original recording quality and source are the limiting factor, so much more than anything else. Update: DS2 arrived. I am ready to test it on my 3.8 kW mobile system, but I am waiting on a Topping PA 7 Plus to arrive (for...

    Fosi Audio DS2 Portable DAC & Amp Review

    Thanks Jason. I believe I have the right cable for the job to go from the Fosi DS2 to the miniDSP Flex balanced as Amir reviewed here: https://www.audiosciencereview.com/forum/index.php?threads/minidsp-flex-review-audio-dsp.30804/ I just hope the gain levels/impedance/balanced all works out ok.

    Kind of a silly question for ASR

    Fosi Audio DS2 Portable DAC & Amp Review

    Thank you for that info Jason (still waiting on mine). If I understand correctly, does this mean it will provide a properly balanced common noise rejection output for input into something like a miniDSP Flex balanced (with the right cable)?

    I believe that is the superseded "2023" model.

    Fosi Audio DS2 Portable DAC & Amp Review

    I am a little surprised by the lack of interest in whether the balanced out of the DS2 is actually connected to a common ground - surely this is important for anyone wanting to use the balanced out as - a balanced out. UPDATE: Fosi contacted me and said there is no stock, and asked if I am...

    Paid for one on the 10th and still waiting for dispatch. @Fosi Audio are there delays in shipment?

    Fosi Audio DS2 Portable DAC & Amp Review

    Do we know if the balanced out on this has a ground yet? Some of the issues others are experiencing are concerning, also.

    Fosi Audio V3 Mono Amplifier Review

    Bomb-proof construction, Duratex coated, mobile usage, but high-end hifi componentry.

    Fosi Audio V3 Mono Amplifier Review

    Depends on the regulation, but such a device simply cannot deal with the thermal load of a 480w output.

    Fosi Audio V3 Mono Amplifier Review

    It does say "10A(MAX)". But to steel-man your position - if it can reach 10A even for 10ms I will eat a Fosi Audio monoblock and stream it.

    Fosi Audio V3 Mono Amplifier Review

    They are already pretty cheap. And it is a bit nit-picky - but it matters to me, because I like to run 8-ish Ohm industrially built DIY "audiophile" two-way bookshelf speakers, and big-a** 2-ish Ohm subwoofer, all nicely crossed over - at too loud volumes. Without distortion. Very efficiently...

    Fosi Audio V3 Mono Amplifier Review

    $20 bet: One of these amps on a single 48v 5A power supply provided by FOSI, will score a higher power rating at >1% distortion and 2 Ohms on a dyno, than it does when two are connected to the 48v "10A(Max)" power supply provided by FOSI (also, it will have a lower noise floor).

    Fosi Audio V3 Mono Amplifier Review

    When Big D (Williston) did the max power dyno run at 1% distortion at 4 ohms on 2x mono amps using a y-splitter on the "10A" power supply, both amps engaged a safety power off. When he used a single amp on the "10A" at 4 ohms 1% distortion, it did not do a safety power off.

    Fosi Audio V3 Mono Amplifier Review

    Might be best to get a "10" amp for each mono for loud, low ohm usage.

    Fosi Audio V3 Mono Amplifier Review

    Yes, they are nowhere NEAR 10A power supplies. Big D just repeats what the Fosi supplied ones say. The model number where it says "48063" denotes it as a 48v 6.3A power supply. I would be surprised if it could reach 7 amp for more than a few milliseconds.
