Fosi Audio V3 Mono Amplifier Review

[Chipk]

Just got my tracking id. Email says 1-2 weeks.

I've just had the following message from Fosi.

Thank you for supporting our V3 Mono crowdfunding project on Kickstarter. We have shipped the reward “EARLY BIRD | 4 sets | 20% OFF” to your place and you may receive it in the coming 1-2 weeks. Please monitor the tracking information via the link below.​

TRACKING NO
Thank you again for your great support!

It would inspire more confidence if they listed my entire order, including extras. I'm keeping my fingers crossed that everything arrives.

I believe they're shipping batches in Kickstarter pledge order. I was #37.

Vague, ambiguous. Does this mean they shipped the reward separately from the main order?

No, in Kickstarter the entire order is the reward. Go to your Kickstarter page and click the reward button at the top to see what you signed up for listed. I have done a couple of previous Fosi KS and this response is normal.

Probably a form letter that everybody gets when their order ships, no matter what it contains?

The mono version runs the TPA3255 amplifier chip in the parallel bridge-tied load (PBTL) mode. It doubles to current output capacity of the stereo version by running both channels in parallel, but it does not increase the voltage output capacity.

The PBTL mode is useful if your loudspeaker has very low impedance (< 4 ohms). It offers very little advantage if your speakers' impedance does not drop significantly below 4 ohms for a large part of the frequency range that demands high power (such as <200 Hz).

Thanks for your answer !
So for a low sensibility speaker (86db, needs 200WPC), TPA3255 is perhaps not the best choice.. any recommendation please ?
Thanks

How loud are you listening? A quick check indicates that making a sound as loud as a pneumatic drill (91dB) at 3 meters from your speakers (allow 6dB headroom in case you want louder peaks!) with your speakers needs 113W ... That's loud for little amps and normal home hi-fi. Do you really need that?

You'll be lucky if you'll get it in August/Sept.

What do you reckon for #697 then :-(

It's true, I can listen a little bit loud
But more true, the room is 45m2 and listening distance can be around 5~6 meters... perhaps that's the problem
I was surprised to use the BT20Pro at 80~90% power rating.. and prefer to have some power reserve... but perhaps V3 Mono will improve that

Fair enough, that's a decent amount of space to fill. Might be worth opening a new thread and setting out what you are looking for

It would only make sense that they ship everything together (apart from the SP601 speakers, which will be delayed). As yet I've heard nothing from Fosi to confirm what items I've backed. It makes sense that they should do that before shipping as correcting mistakes and misunderstandings after they've already shipped is an expensive way to resolve mistakes.

I was backer number 35 and have not received any email or tracking info.

I was backer number 35 and have not received any email or tracking info.

I’m number 7 and no email either.

Curious.

 

[P1NBA11ER]

Backer #1 for 2 units, dual 5A supplies, a shirt and some cables. No email either.

 

[rusnak666]

Backer n.10, email from yeterday: Shipment information received... infromation from today: Mainland China, CN, Arrived at origin facility...

First backer of all people should have gotten an email! I got mine and I am backer #27.

Backer #1873 checking in. Should get my email any moment now… right? … right??

Same here, backer #15

If your order includes 10A supplies they are custom made, this maybe a delay? 5A are easier to source, my suspicion is the 5A orders have gone out first.
Backer 148 (5A) and have had a shipped notification.
