Assuming you're referring to the ZD3? Anxiously awaiting news/updates on this. Have a couple potential use cases for it, including pairing it with dual V3M's.

@Fosi Audio any hint on when we might hear more about it?
They're talking about a pre-amp. And I agree with another person, it needs a remote
 
Yes, we're making one with XLR balanced and RCA output.
If i had to buy one i would want it with tone controls with tone defeat, 4 inputs (one or two digital in), bt and streaming, for me it would be radio,net,dab radio, mabye fm (don't need a remote, mabye some do)

Price as one fosi audio v3 mono amp 159 euros at audiophonics mabye 450 euros for the 2 amps and the preamp with basic but good streaming

What I am really interested in is integrated HPF/LPF/crossover tech from Fosi to drive passive 2.1 systems. For example I currently use the BT30D Pro because it removes the sub output from the main stereo output. For some strange reason the ZA3 and V3 lacked this. But the BT30D Pro is somewhat underpowered and lacks the audio fidelity.

These amazing monoblocks are...well, amazing - and I could integrate 3 of them to run my 2.1 setup (or maybe a ZA3 and one monoblock for the sub). But without some form of HPF/LPF/crossover function, it is unworkable, and I don't really want to buy and integrate an extra dedicated crossover device.

IMHO, DIY passive 2.1 systems are the most affordable way for people to get into full-range high fidelity audio.

Nope. Prioritize DAC, power, signal, inputs, outputs. Give us 12v trigger and a remote. Bonus for phones and their magic, but unnecessary. Beat the DX3Pro+.

DAC? I think you are on the wrong thread. This is an amp.

Also, I am talking about what I want - not what you want. Plus the post got 2 likes in minutes.
 
Considering the major issues I had with trying to get previously owned devices' signal sensing to function properly (e.g. simply not turning on with music playing at what I would consider a reasonable, if not necessarily 'loud', volume), I am firmly in the camp of the 12v Trigger Partisans. I note that none of the reviews I have read or watched of the V3 Mono so much as mention how well the auto sensing works on the amps; I take that to mean either it works well enough not to be an issue, or (the pessimist in me) nobody actually played around with it. Hoping desperately for the former.

smsl makes on the smsl a50 pro but for a passive subwoofer https://www.smsl-audio.com/portal/product/detail/id/867.html

It would be very interesting to see Fosi make a balanced pre-amp along the lines of the Schiit Freya/Kara, Gustard P26, ...
Dac that can be used as a preamp like a topping E30 ?

There's already 1 of those coming out like every other week.

Just like with the monoblocs, I'm hoping for something different, something that usually costs too much because it is a niche product. But when you can make them perform great at a very affordable price, it becomes a hit.

Monoblocs are nothing new, but with the V3 mono, everyone can afford it, and many want it. It would be awesome if they could do the same with a balanced pre amp. Not another dac that can also do a bit of pre amping.

2 balanced ins, 2 or 3 SE ins, nice buttons and volume control.

Currently many use their dac as a pre-amp, because it's not worth spending 800, 1100 for a dedicated pre. But a good dedicated pre makes controlling your audio so much nicer.
 

TOPPING L70 is balanced​

You're missing the point. That's a headphone amp that can do a bit of pre amping. I am talking about a dedicated pre amp.

Not a dac with a bit of pre amp, not a headphone amp with a bit of pre amp, not a streamer with a bit of pre amp. Just a pre amp. You don't know how nice it is until you used one. I still miss my Yamaha C-2.

Fosi should not try to compete with Topping and SMSL. Those are already disruptors.

If I want a dedicated pre amp now, I am paying (a lot) more for it than for 2 V3 mono's + E30 + L30. That's not worth it for just nicer volume control and dedicated buttons instead of multifunction.

But if you could have a dedicated pre for the price of a good dac, that would be awesome. It doesn't really exist. Plenty of choice if you want to spend a lot, but no options if you don't want to pay more than the price of 2 V3 mono's.

I know, but getting one serviced can get pretty expensive. If Fosi can do for pre amps what they just did for monoblocs, that would be pretty cool. And it seems right up their alley. Why make another dac+pre combo, everyone who wants a Chinese one, already has one with sinad off the charts.
