FOSI Audio GR40 Tube DAC Amp ES9028Q2M - Great Affordable Tube Experience

[@bamskie2024]

Your intro is getting better everytime andy! Great and straight-forward review as always :)

[@AndyAudioVault]

Appreciate the kind words! 🙏

[@lasttempoinparis]

Cool review of a typical All in One solution (note, GR40 is decoding DSD256, nice). There is a bundle free shipping on Fosi Ebay : $210 cut to $147 with an external Fosi V3 speaker Amp. unit 😎 You save $63 to buy plenty more Tubes 😊

[@hokagoteatimereviews]

Thanks for the great review Andy 🙂

[@AndyAudioVault]

My pleasure

[@danielphillips1171]

Hi Andy, do you have any plans to review 7Hz Timeless 2? Many thanks - superb channel!

[@AndyAudioVault]

Yes working on it. Thanks

[@JambuwantBhalu]

Tube sounding technical is 😎

[@yizhakbn]

Thank you Andy! My current setup is Onix alpha and Hidiz mp145 (also has the Delci AE) that I've learned about from your reviews and I’m very satisfied, do you think this GR40 will give the mp145 the tube effect? Didn’t really had a chance to expirience to this kind of sound.. or maybe Fosi Audio MC331? or xDuoo MH-02? i'm kind of lost in this area. Thank you!

[@AndyAudioVault]

Yes it does, and in a sublime way which I feel the endstate of it the sound being pleasant and enjoyable

[@yizhakbn]

@@AndyAudioVault Thank you! i will order 🙏

[@yizhakbn]

@@AndyAudioVault I have one more question please, this will be suitable to run Hifiman HE400se magnetic planer and Fiio FT1? Thank you again!

[@AndyAudioVault]

HE400SE is less demanding than Sundara or HD600, so you will be okay there. FT1 also seems to be efficient as well, no worries

[@yizhakbn]

​@@AndyAudioVault Thanks, i Appreciate your answer!

[@hariotmarriot9347]

Hi. I hope u will review onix overture xm5 next. I heard its very good for vocals. Cheers.

[@AndyAudioVault]

Thanks. That's my wishlist too

[@whysoseriousxy]

Fosi Audio really good brand for audio. I like them so much. I need to buy an IEM. Only Sennheiser is sold in my country. And they are over my budget. I could only find these as chifi in my country. Which one should I buy? I usually listen to metal music like you. - 7hz salnotes zero - 7hz zero: 2 - moondrop chu 2 - kiwi ears dolce - truthear gate

[@AndyAudioVault]

If those are the only options, then I would pick Dolce

[@whysoseriousxy]

@AndyAudioVault Unfortunately, Kiwi ears dolce is out of stock now. What would you recommend among others?

[@Helmond2017]

Kudos to the Fosi audio team for establishing a design that's easily recognizable as a Fosi product. I am gonna get the V3 or za3 for my speakers.

[@poyocru]

Satyricon!

[@Avdeupol]

Hi Andy! You recommend Onix Alpha 1XL and iBasso DC 07 pro dongles. They are both very good. But I can only buy one of them. Which one should I buy better? Or which one of the two would you keep for yourself if you had to choose?

[@AndyAudioVault]

Which one you buy is up to your budget because I love both equally

[@Avdeupol]

@@AndyAudioVault ok

[@TheWanz1]

hello andy, i'm still new in this audio stuffs, so i hope you can explain it to me in layman terms. is this desktop dac amp will be able to power others famous headphone such as sennheiser, beyerdynamic and so on. so far i only have hifiman He400Se which is my very first planar magnetic headphone. or do you have any recommendation for other desktop dac amp which is more "wallet friendly". thanks in advance andy!

[@AndyAudioVault]

In this video I have mentioned that it can drive Sundara which is a little harder to drive than HE400SE, so yes no problem there

[@DarenLee]

For a moment I thought Andy has step into bookshelf speaker stuff as this looks exactly like my speaker amp Fosi V3 😉

[@AndyAudioVault]

Lol, I do have bookshelf speaker now. Those are Advanced Acoustics Audio speakers 😎

[@DarenLee]

@ that is dangerous water you are stepping into, I stop after finding out much more competent pairings are available for speakers like the Linear Power Supply thing, and earthing device and cables and never ending 🙈

[@AndyAudioVault]

🤣

[@herbcohenflow7867]

I have a Cayin ru7 at 300 mw seems powerful enough but has some warm color on the low end I really enjoy. Does this tube amp offer a more warm organic sound as I that is why I would get such? I did not sense that as a particular strength of this amp.

[@AndyAudioVault]

Warm sound? this GR40 is not exactly warm like some other tube amps. But you can tune the Bass/Treble to a point that it becomes warm by cranking the Bass 2 clicks + and Treble 2 clicks -. It will be colored but it will be as warm as you can get. I would say MUSEHIFI M5 Ultra is warmer by default

[@whysoseriousxy]

Unfortunately, Kiwi ears dolce and truthear gate is out of stock now. What would you recommend among others? For metal music. - 7hz salnotes zero - 7hz zero: 2 - moondrop chu 2

[@AndyAudioVault]

Chu 2

[@Emre-nl8df]

Finally my family allowed me to shop abroad. What should I buy for metal music for Max 30 euros? Also thanks for video i should buy an dac and fosi audio really good look.

[@AndyAudioVault]

@@Emre-nl8df Get Kefine Klean

[@Emre-nl8df]

@AndyAudioVault over my budget max 30 euro. Tanchjim ONE is good?

[@AndyAudioVault]

Yes

[@Emre-nl8df]

@@AndyAudioVault thank you so much

[@juliandaniel5357]

Hi Andy, I’m about into IEM, and interested in dongle DAC FiiO BTR17, would you review it, please?

[@AndyAudioVault]

I plan to review BTR17 but I have no idea exactly when. Let's see if this can happen either in Jan or Feb

[@juliandaniel5357]

@ thank you so much! I appreciate it. I just need validation before buyi this thing. Lol

[@harijskilmits1196]

I love the Odo dongle with my HD560s. Would You or anyone recommend even a better one for 560s? I use USB audio player pro. Thanks.

[@AndyAudioVault]

For under $100, I would recommend AKLIAM PD6, but you will need to run it on 4.4mm BAL. For SE, this GR40 is also suitable

[@frankmiller8393]

Hi Andy Frank here from UK my son has just landed in Taipei Taiwan he wants to buy me the best budget iem in Taipei. Any suggestions? Best Regards Frank

[@AndyAudioVault]

Hey Frank. Best budget under $50 now would be Kefine Klean 🙏

[@frankmiller8393]

Thanks Andy

[@Temdanthu]

Still waiting for Andy to review the Questyle M15i haha

[@AndyAudioVault]

At this point, let's just say I will not be doing M15i. I would like to but it is unlikely it will happen as Questyle have yet to send me one. Thanks

[@Temdanthu]

@@AndyAudioVault Understood, thank you :D

[@technologyinformation4748]

I have blon bl03 i want to upgrade iem so please suggest me best iem under 120 dollar and or 70 80 dollars both price points

[@AndyAudioVault]

I f you like BL03 then I think you will find LETSHUOER S08 to your liking. Better tuned overall vs BL03

[@technologyinformation4748]

@AndyAudioVault blon have ear pain bass sound not comfortable

[@technologyinformation4748]

If you hear any 70 watt deep bass blutooth speaker tzebronics Zeb feast 500 then recommend me iem under 45 dollar

[@afiqir5158]

Wow, i thought going to be around 300 to 500 usd

[@Zadym]

Is it worth buying something more expensive than this DAC Amp, for 32 Ohm headphones, or is it a waste of money?

[@AndyAudioVault]

32 Ohms, as mentioned in this video is perfect to be used with this GR40, especially if you are running only 3.5mm SE connection

[@Vandikaarar]

Andy do fiio KA15 and ibasso jr macaron #donglemadness

[@AndyAudioVault]

Working on Macaron now
