So after several trials my FCN10 is not able to do airplay (I’m using iphone 12 pro max and latest iOS) : my fcn10 is well connected to my wifi network and I can see fcn10 as an airplay device on my Deezer app, but when streaming music the Deezer app says that connection to fcn10 is not possible and then I can’t see anymore fcn10 as an airplay decice. Of course I got some support from Vitaliy.

That’s too bad because I sold my FA-10 and Chord Mojo because I was tired with cables, for now I connect my iphone to fcn10 with USB cable : I won’t return the fcn10 because with my HE6se the combo is superb.

For those interested with fcn10 for airplay, beware that it may not work.
Would trying a different operating system for the raspberry pi help or have you already tried that?

No, I don’t want to take this road

UPS says I should have my FA-12S delivered tomorrow :) From the folks here who already got their, what sort of burn-in did you go through and were there any specific things you did which helped?

Just power on your Fa12 around 15-30 min before listening to music

I let my FA-12 run in for 2 hour before listening. And about 100 hour in it settled.

My FA-12S was delivered today.

Must say DHL was fast as it shipped last Thursday and made it all the way to Canada in less than 120hrs

All told it took 33 days after ordering

Will post pics later tonight

There's some gear I've had that have benefitted from burn-in, but the FA-12S wasn't one of them for me. Vitaliy hinted in an email there might be some subtle shift as the amp hits steady state operating temp. This is in theory broadly the case for electronics, but I find the impact de minimis at best. YMMV.

I've found that the amp can take some time, up to a couple hours, to reach a constant temperature but seems to reach optimal performance after 30 minutes or so but probably less than that. Might be fun to see what you think as the amp warms up. I haven't noticed any break in but haven't really been listening for any changes either.

All set up and did some listening in the little time I had tonight. It’s VERY early but I’m enjoying the sound even though I’m straight out of the box at this point

The build is nice, feels hefty and the finish is very good. All the switches and volume knob feel like quality pieces.

For those curious I ordered it specifically with a black volume knob so it would match my other gear and also ordered the remote option which works fantastic

May I ask a newbie question. I want to buy an amp to drive Hifiman HE6se v2, which is known to be power hungry. What is the difference between FA10 and FA12? They seem to be identical in all specs. So FA12 is a better balanced design, but FA10 is more powerful?

I am currently using Singxer SA-1 with HE6se. I feel it does a decent job.

The simple answer is that the FA-10 is significantly more powerful than the FA-12 so I would choose the FA-10 to pair with your HE6SE. The FA-12 is fully balanced while the FA-10 is not. They are both class A. They are both the same size with the same controls. FA-12 can only do single ended in, single ended out or balanced in and balanced out while the FA-10 can output of both outputs regardless of the input used.

The FA10 is single ended amplifier and outputs a lot of power (up to 16watts)

The FA12 is a balanced amplifier and makes substantially less power (although it does have plenty of power when headphones are connected to its balanced output)

They sound slightly different as well. The FA10 is known as a neutral sounding amplifier whereas the FA12 leans more to the warmer side.

If it is anything like the HE6 and needs gobs of power, then the FA-10 is your match. I wouldn't get hung up on Balanced.

I generally dont do any burning, but my fa12 has got a bit of refinement with time.
About warming I just turn to play, but about 30min in, the fa12 reveals itself.

Mine still appears to be stuck in customs and clearance hell somewhere on the UK border. UPS even took away the estimated delivery date :frowning2:
