Fosi V3 Mono vs ZA3 -- Which Fosi Wins?

[@ajzepp8976]

I have a handful of V3 monos and also one of the ZA3 units. The ZA3 for the money is a great piece, but I added a pair of the v3 monos to a schiit saga2 (balanced connection) and was blown away. I even have it driving some Magnepans, and the results were incredibly surprising to me.

Fosi is getting ready to release their balanced DAC for these amps.... can't wait to get one.... also... I got the Hifiman speaker adapter to use with the V3 mono amps... so now my headphones are sounding amazing and I don't have to worry about not having enough power... the HE6se v2 sounds amazing with that much power... whats there not to like... they take up very little room and they sound amazing for a headphone amp....

The ZA3's have 12 v triggers so that you do not have to leave them on all the time.

My 2 Fosi Za3 are not hot too touch ifI turn them off after each usage. On the other hand, the 2 Fosi V3 mono are cool as cucumber. Thanks to the stand by mode. Match the Fosi V3 mono with the Fosi tube buffer pre P3 is a match in heaven for the price.

I ordered muses02 op amps for the V2 monos because the sparkos complements the Za3 better but the v3 needs the chill of the muses02. Funny I thought the v3 sounded more “open” than the ZA3. The Za3 doesn’t sound good with 1 unit. Much better running 2.

Yeah! I agree, its better to spend a bit more and leave the regrets behind. Thanks for posting this video.

I love my v3 mono's a ton but they get scorching hot. I have the za3 too might get two more and run them in mono, they run much cooler....

Grab a fan, my V3 Monos run hot as well but putting them on their side and using a fan below them works wonders.

I just ordered some-I don’t like heat generation-if I like them, I think I might get 36v or 42v power supplies to replace the 48 volt. Supposedly limiting power to the amps will keep ‘em cooler-sure you won’t be able to play em quite as loud, but I have never needed 240 watts.

@@kineahora8736 Don`t make a mistake! They do not sound as good with 36/42 V as with 48 V Power. 48 V 5 A ist the best. If you don`t touch them, you don`t know that they are a bit hot. 😉

[@kineahora8736]

@@misterl7771 yes but my apartment is hot as hell always. Dammit. I did order them with the 48 V/ 5 amp (two separate power supplies- I didn’t want to get the single 10 amp with the splitter) I’m going with the muses02 op amps to chill the sound out a little bit… I probably spiritually would be better with the Z A3 which is a little darker- but I decided to go V3 with muses02 vs ZA3 with sparkos…

Did you set them up with Auto mode. My 2 V3 monos are cool as cucumber and I like it. That's said my room temperate is set at 74 F.
