Fosi v3 Mono | TPA3255 PFFB | Balanced | [First Look from Fosi FB]

[Talisman]

I'm extremely curious! This could be what I've been asking for years... I just need it to be sufficiently non-dependent on the load, with a sinad over 85 and at least 100watts into 8ohm at all frequencies and I'd take 5/6

i think it's C chassis

PFFB: very good - Balanced: good - but why mono(only?)block?

Amazingly low crosstalk measurements!

 

[sejarzo]

Hmm, if they put this out in the sub-$200 range (maybe $150?) then we're probably looking at a lot of clean watts per dollar here.

It really needs to be sub $200. If it is $200, I would spend the extra $90 or so and get the Audiophonics in a nice case with internal PSU. Not a fan of external PSUs, and even less of two external PSUs.

Audiophonics 3e TPS3255 variant is attractive indeed.
But I wonder why would you choose it over hypex S250nc (or another hypex) variant, considering overall performance for circa $500 !

Thanks for noting that. I now realize I saw the price for their Hypex S250NC unit before I logged in as a US customer, so it included 20% VAT that was deducted from the 3e-based amp price that I saw after logging in.

While that makes the Hypex-based unit cheaper, it costs more to ship the Hypex than the 3e amp, so in the end, they are within €9 or so net price to a US buyer. Either way, the Audiophonics S250NC amp is cheaper than either the VTV or Buckeye.

I don't know how the import duty is managed when something like this is imported from EU.
Anyone has some information or experience?

 

[Joe Smith]

Yeah, for me, cost is issue one and issue two is the need for separate power bricks. I am really only interested in "all in one" monoblocks with internal power.

According to what I have read on US federal and the DHS and UPS sites, as long as it's declared value is under $800 US, there is no import duty assessed.

At $150 each/$300 all in, or same price as two ZA3s, I would tolerate multiple bricks, but at $200 each, I'd buy something else.

Some of the comments on the thread re this amp on the Fosi Facebook page...oh dear, oh dear, oh dear...

A current customer seems to be disappointed because it will use feedback (which he doesn't trust) and that Fosi doesn't supply a nice audiophile grade linear power supply.

Needless to say, when I pointed out the similarities between Class D and SMPS technology, the need for feedback, etc., he replied that he wasn't schooled in electronics but just wanted the best sound possible.

Thanks, I didn’t know this.

I don’t mind external PSU, always somehow manage to hide in the rack.
However the overall package must make sense considering quality, performance and price value.

As in someone has got a test unit?

No, just someone who believes in snake oil and noted that he feeds his audiophile Class D amps (with special PSUs those makers claim are superior) with a tube preamp...and thinks he hears a difference in power cables.

Ahhh… I get it.
Well…he isn’t alone… hope he gets what he wants

 

[sejarzo]

As is always the case with Fosi, the big question is "OK, but when will I be able to buy one?"

Hope you understand the degree of eagerness some people have here for this .
