Interesting. Virtually no info available. Femto looks sweet though.

The femto had a price yesterday but now it's gone, I think it was under 600,00€. Femto looks like just an updated version of the UPre. I researched the UPre and found a couple location sound houses in France renting them but none for sale.
I'm really curious how these sound.
I'm going to email audioroot and inquire about the Femto. I'll post here whatever I find out.

600,00€, What!!!!! Why? i could see that if it was also a two channel mixer.

"The FEMTO will be available in late february 2013"

They probably removed the price because you can't purchase it yet.  I think it was 560 EURO's.

Heard back from Antoine at audioroot. First couple units have gone into production. Like his website says he plans to have tech specs and price available by the end of next month.  He did say the femto will be less expensive than the upre, but cost still undetermined. I'm curious too hear how this French made preamp sounds. I like the specs of the upre just not the price hoping the femto will be more reasonable.
Regards,
Jim

Hey now,
I was contacted by audioroot and the femto preamp is now available. Web page has been updated with more info. Price $645 USD and that includes shipping to US or Canada.
Who wants to be the Guinee pig??

I asked audioroot if the femto used input or output transformers in the design since their previous model, Upre, has input transformers. Since the femto has XLR input and runs on 2x9v their simply wasn't room. I'm probably going to pick one up and see how it performs.

Hmmm.  Kind of looks like a Little Box with more elaborate metering and slightly better cosmetics, and at twice the price.

It's more midbox sized though.  I kinda think the title is funny, because my naming convention would put midbox at milli, littlebox at micro, and tinybox at pico.  Femto ought to be smaller :D  It's very attractive though and the OLED screen is beautiful.

Keep in mind that I had a very different design philosophy.  Most portable pres are an attempt to run a studio-grade preamp off of batteries, so they have lots of gain (70dB for the Femto) and very low input noise (-129dBu).  Those specs always come at a cost; either input transformers ($, space, and weight) or power.  So Femto idles at 31mA, presumably at 18V (batteries in series, so they aren't hotswappable?), that's 558mW, vs. about 90mW for a tinybox.  The Femto is also spec'ed at 67mA (1.2W) with a pair of CMCs, those draw 4mA each, for 384mW.  So that's about 65% efficient on their phantom conversion circuit; tinybox actually exceeds that a bit, around 70%.

Thus, they end up with a six hour stated runtime for 2x 9V (11.3Wh--it should be longer at nine hours given 1.2W) with the CMCs.  tinybox would manage over eight hours with the same load--but tinybox also has a low-volt phantom option which can run CMCs for over twice as long.

So why spend the power?  Again, for high gain bandwidth and low noise.  That is of benefit if you are using quiet mics on quiet sources.  That's why I have a low-noise amp option on tinybox, which doesn't quite hit the Femto's noise spec; -129dBu is impressively quiet.

Oh god.  Now I need to think about a metric conversion for naming conventions. :P. I actually didn't really look at the size, mostly the layout.  I suppose it is a mid priced unit in the scheme of things.  Less expensive than a V3 or a USBPre2 (but with no ADC) and more expensive than a Tiny Box or a CA9200.

This is more geared towards the ENG market and the price/specs and build design reflect that. I think its appropriately priced. Certainly not cheap but cost about what a sound devices mp2 did. Every preamp has its own flavor and I guess until someone tries it for what we do, we will never know if it worth it's price:-)

It does have enough gain to drive ribbons and dynamic mics.  Actually, you are right.  $645 for two channels of high gain, low noise preamp is pretty decent.  One channel of a typical 500 format preamp generally runs about that or more.  Interesting.  It is very cool that people design and manufacture this kind of stuff for our niche market.  I am interested to hear a real word review.  Lord knows I don't own enough preamps. ;D

500 series stuff is way overpriced.  Consider the Femto, it has a full case, internal battery tray, power supply, and connectors.  A 500 module doesn't have any of that.

I think this is why Fivefish decided against putting his TS-2 into production; why bother when studio guys were paying more for his 500 series stuff, which was a fraction of the effort?
