Easy mistake to make.

Having read a bit of this review I went ahead and ordered a Fosi V3/48v PS from Amazon. I have this driving my turntable/Parks Audio Puffin/Topping E30/GoldenEar Triton 2's/Paradigm PW2100v2's. All I can say is WTF???! I have a Bryston 4BST and a ARC SP9 and I cannot believe what I am hearing from this little amp! Am I fooling myself? Well, right now I will be keep drinking and running this combo for a while!
Cheers, Doug

Cool…
I didn’t know that Amazon has v3+48v combo.

 

[plastico]

Well, Amazon.CA has it. Cost me $203 bucks Canadian with the 48v PS.

I don't see that as a combo available on Amazon. ca, only separately with 32v supply and buying after the 48v?

 

[plastico]

Yea, you have to purchase them separately.

You will see it as

Frequently bought together.​

@Fosi Audio
Do you have any plans to sell v3 amp with 48v adapter on Amazon US in near future?

UK was only offering the V3 with 32V, Now it has it with the 48 also.

But look at this rather silly pricing. I can now buy the V3 with 32V AND buy the 48V PSU for only £5 more than the V3 with 48V. So I shall start with buying the 32V PSU. Then if I decide I want the 48V, I can get it and have a spare plus the chance to do comparisons.


And that is ridiculous. Just ordered at 8:30am - it will be with me by 7pm today.

I find it Bizarre they don't just bundle the 48 Volt PSU with the V3 and sell it on Amazon. (.ca and .com) It would save a lot of PSUs heading to the recycling bin.

One really should have the option of ordering easily with either of their power bricks. Seems odd they are not making that easier to do...

I think they will (just as they have here). I'm guessing it is a process of getting the supply chain pipeline set up.

 

[plastico]

I am thinking that it's an add on so they make it like an option.

And they haven't tried it on aliexpress, it's cheaper and they can choose with or without a 32 or 48v power supply. Although you must pay shipping.

So it arrived by 6pm yesterday. Set it up this afternoon. I have it in a desktop setting in our spare room with a pair of Wharfdale Diamond 9.0 speakers. This was a £40 pair of speakers on offer when I got them a few years ago (though selling at £100 now), so I am not expecting miracles.

In spite of this it sounds as good as I could expect from those speakers. From a power perspective, it can output more than the speakers can take. I doubt I'll be investing in the bigger PSU unless I change where it is used.

It is certainly not lacking bass. In fact I've had to turn down the bass with a graphic EQ in the 128 to 250Hz region - due I suspect to desktop resonance.

I've been running it all afternoon. I can detect no temperature rise at all (with the calibrated palm of my hand)

Amazing for £85

EDIT - and the volume dial has a really nice feel to it.

Hell - these speakers are sounding better than I believe they have any right to.

Tempted to try the V3 with my "proper" speakers now. Though It will be a pain in the ass to set up.

This Class D amplifier seems to truly outperform my IOTAVX SA-3 Class AB amplifier? Could this be indicative of a trend where Class D technology gradually supersedes traditional Class AB designs in the audio landscape in the coming years?

Yes.

Not too long from now (but perhaps longer than it should be in the... err... high end... market, for the usual reasons), class A and AB amps will be viewed as dated as tube amps now are.

I've read a few comments saying that the V3 with larger power supply sounds better even at low volumes. This seems unlikely. Is there any benefit other than greater volume of the larger power supply?
