Hi @FiiO
Any update on expected K19 availability in the US?
Thanks.

Dear friend,

Hi, thanks for the interest. At the end of this month as well.

Best regards

This new FIIO K19 "balanced" amplifier is interesting, but is it fully balanced?:
- Balanced XLR4 headphone output - has
- 4.4mm balanced headphone output - has
- Balanced output 2x XLR - LineOut - has

But where is the balanced 2xXLR input - Line IN?

Is k19 an overkill for fatfreq scarlet mini IEM?
got k7 at the moment and i wonder k9 akm or k19? there will be even diffrence?

At the Fiio booth for Can Jam Singapore 2024, I tested 2 upcoming IEMs.



First up, we have the Fiio FD15, a single DD that should retail for around $150 - 200 USD.

This sounds very safe, U-shaped with safe upper frequencies. Timbre is organic and very natural. Technicalities are quite good for a single DD with nice sub-bass rumble.







n the second photo, we have the Fiio FA19. This is a 10 Knowles BA set, I think it should retail at sub $2K USD and is one of their higher end offerings.

The FA19 has 2 tuning switches, and is neutral bright, very technical beast. Transparent and clean sonics. Their previous FX15 was a bit hot in the upper mids, but this one is safer in that region, but more technical to boot.

Are there any news on the Fiio M27?

Saw somewhere that they will be selling this cable separately (LC-RC 2024). Will it be shipped with the new FD15?

Hi @FiiO, is this the same chassis as the FA7S/FD5, but only with a different faceplate? Or a new design altogether? Thanks!

I saw the fuse of R9 is placed at the iec socket which is easy to upgrade. I found no on the K19 iec socket. is the fuse moved inside? or no fuse at all? what is the spec of the fuse?

@FiiO why don't you try to use 2 in parallel buf634a (in optimal thermal pad package) output configuration instead of OPA926 to TPA6120A2 switchable output for new devices? Switchable BW biasing in this configuration should be a win! There is even no need to use series resistor to provide very small internal impedance due to buf634 has internal thermal protection.
(De)motivation: I'm little frustrated and tired to see hyped THX AAA 788+ measurements, where distortions in non-desktop supply mode (OPA926 output?) drammatically increased on 10 kHz and above...
(TPA6120A2 is also non hi-res amp. with large internal impedance and added series resistors)

Guys wish me luck

Changing fiio k7 + PL 50 power supply to K9 AKM

i hope i will be satisfied , 2x the price of current setup.

I bet you will!

Dear friend,

Hi, yes,it looks almost the same as the fd5 with just a new cover, but in fact the shell has been changed a lot: improves the wearability by modifying the shape, the angle of the sound tube, etc; the internal design also improves the wearability by changing the front and rear chambers and the shape of the eq.

Dear friend,

Hi, the K19 does not have external fuse like the R9.

Dear friend,

Hi, which product are you asking? I could try to check with the product manager for you.
Thanks in advance!

Hi, which product are you asking? I could try to check with the product manager for you.

I mean desired hypotethical product using 2 in parallel thermal-effective (non SOIC) packages of BUF634a (x8 total) in balanced output stage with no addition of serial resistors and no semiconductor mute-switches after BUFs (equipped ES9038pro or AK4499 DACs). That should provide 500 mA continuous load ability and great electrical damping-factor for low-impedance IEMs (and some HP).

Thanks for feedback
