    सर, जब आपने पहली बार अपना चैनल खोला था तो यह सूचनात्मक सैद्धांतिक वीडियो थे, लेकिन धीरे-धीरे आपके वीडियो प्रमोशनल वीडियो बनते जा रहे हैं, पहले मैंने सोचा कि आपका चैनल दूसरे चैनलों से अलग ।लेकिन आज की स्ट्रीम में आपका वीडियो कंटेंट किसी अन्य चैनल जैसा होता जा रहा है। मैं उम्मीद करूंगा कि आपको अपने चैनल पर पहले की तरह ज्ञानवर्धक वीडियो मिलेंगे। नमस्ते

    Amazing review sir!
    For me its not possible to judge the sound quality but your words brings confidence.
    ‘Sound not so attacking, harsh treble
    Mellow and soft sound ‘
    All these attributes make me imagine the sound in the light of your understanding.
    I wonder if you can get some music from your friend’s instrument or voice of your own
    That would prevent you from legal issues.
    And then the comparison of the sound with or without the amplifier etc.
    i trust its easy for you sir!

    Greetings Sudhir Ji
    As usual :D Its not that easy to impress you , you found cons in here as well :)
    One question about it - whats the difference b/w the audio quality via BLUETIOOTH and RCA ports.. I have noticed there is always a difference , either the BT audio sounds better in some boards or in others Aux sounds better.
    I had just looked at this amp yesterday on amazon and liked the specifications and BAM!!! here is your review the very next day , great coincidence.
    I am still using your fav XY-T100L ( its my 2nd amp as I had accidentally burned the regulator chip on my first XY-T100L) and also bought a 50+50w XY-C50L as well just to nose around.
    You had advised me to look for 3255 based amps back then ( In may 23) .AIYIMA and Fosi look good and are solid performers.. I will be buying this one if you feel among all the 2.0 TPA3255 based amps this one ticks all the boxes.
    Thanks
    all the best
    Take care

    One can buy these kind of small class D amplifiers as these are very reasonably priced but for long term users and ppl who give weightage to overall tonal balance and clarity in all tones like bass, mids and treble class A or AB with good set of speakers are the best options. Hope I am right on that. From the sound demo I can make out that this particular model sounded good only when bass and treble is above 3/4th and vol is more then half.

      only class A amplifier are the best and any technology can not replace it any how. class d is only can be good for low/deep bass. so just forget you can get a crisp and clear sound output from a class d amp. this same guy told us about the same... and now he is promoting a class "D" amp for his earnings (in $)= mind it, anyways its debatable. you guys 1st listen any good class A amplifier or in fact class AB amp then compare any top most class D amp .. you will get my point. class D = money/buisness. Class A= sound quality. Class AB = perfect balance between sound quality and affordability. 1st listen using 1 same set of speaker then decide. do not go for promoted videos like this. money is hard to earn. save it even for years to get the bestest best sound from you money. always listen with your ears practically with any sound device. before making any decision. save this comment as screenshot or copy paste it anywhere. trust me this is the only fact😅. this guy might remove or block me forever 😅😂..

Now i do not have that amplifier but I still remember it's tonal signature. I use a class AB simplistic, no nonsense amp now and I can say all this being a non technical/electronical person. There are class D amps in the higher price bracket that come from European and American brands but I am not sure how they sound.

    Greetings Sudhir ji🙏🙏 , with luck I was able to grab one piece of Fosi BT20A pro , from amazon India :), As it was recommended by you so I decided to go ahead.
    Now after buying XY-T100L (2 pieces, bought 2nd as I had burned the voltage regulator of the first and didn't want to wait but incidentally got the LM1805 regulator from mkt and got the first one fixed and working again :) 😁 ) and XY-C50L this will be my 4th amplifier . I am hoping for a better, wider and clear audio quality :)
    Its still in shipping so will update upon receiving it .
    Even purchased a few good sturdy BANA connectors as well to be used with FOSI with my speakers.
    There was one thing I wanted to ask, now that Fosi has option to change OP amps , can you suggest a reliable place to get genuine OP amps with some info about kind of audio quality that one can expect from them....
    many Thanks 👍🙏🙏

It has a wider sound stage and can woek with all kinds of speakers... With proper preamp and other equipments in audio chain, this could prove top class...
