Bring on the strippers!!!

Anyone got a pic of it in hand or side by side the X5iii or X7 original?

A.D.H.D is real and pictures help sufferers deal with it.:head_bandage:

Just what FiiO already posted on page 2.

It looks about the size of the X5III with an amp module on the bottom to me.

My first question about FiiO X7 Mark II is if support OTG to connect external storage devices?

Why FiiO X7 Mark II not support DSD256 if new Q1 Mark II support it?

Just get it from their website - http://www.fiio.net/en/products/71/comparisons

2.5mm TRRS Balanced Output
MeasurementX7ii + AM3A X7 + AM3X5iii
Output Power 1 ≥380 mW(16Ω / THD+N<1%) >420mW (16Ω / THD+N<1%)≥400 mW (16Ω / THD+N<1%)
Output Power 2 ≥400 mW(32Ω /THD+N<1%) >540mW (32Ω / THD+N<1%) ≥240 mW (32Ω /THD+N<1%)
Output Power 3≥63 mW(300Ω / THD+N<1%) >70mW (300Ω / THD+N<1%) ≥26 mW (300Ω / THD+N<1%)
Frequency Response 6 Hz~60 kHz (-3dB) 5Hz~83kHz (-3dB) 5 Hz~55 kHz (-3dB)
SNR ≥119 dB (A-weighted) ≥115dB (A-weighted) ≥111 dB (A-weighted)
Output Impedance <1.7 Ω (32Ω loaded) <0.3Ω (32Ω loaded) <3Ω (32Ω loaded)
Crosstalk ≥97 dB (1 kHz) 100dB (32Ω/1kHz) >98 dB (32KΩ/1 kHz)
THD+N <0.003% (1 kHz) <0.0008% (32Ω/1kHz) <0.003% (32 KΩ/1 kHz)
MAX Output Voltage >10 Vp-p >11Vp-p >7.5 Vp-p
MAX Output Current >150 mA (For reference) >160mA (for reference) >250mA (for reference)
Drive Ability 16~300 Ω 16~150 Ω 16~150 Ω

Couple of interesting things - to me anyway - is the output impedance of the AM3A, and also the lower recommended "driveability" spec for the X7 + AM3 original (which I assume is a typo as the AM3 is actually more powerful).

In the original specs for AM3 in the FiiO website the Drive Ability for 2.5mm TRRS Balanced Output is 16-300 Ω and 16-150 Ω for the 3.5 Headphone Output:

Seems to be that AM3 is more powerful and best than AM3A.

I also believe it to be a typo because the spec of the AM3 (http://www.fiio.net/en/products/49#AM3) states that the AM3 driveability is 16-300 Ohms. (I currently use the AM3 with a HD800S which is a 300 Ohms impedance headset)

The signal path after LPF looks wrong: L1 (left channel combined) is splitted into L- and R-, R1 (right channel combined) is splitted into R+ and L+. Or, is it too professional to be understood? :wink:

Do third-party apps (i.e. Tidal) play through the dedicated DAC or the SoC DAC? Not buying an Android DAP without this confirmation, after getting burned with the DP-X1

One of their slides seems to suggest that third-party apps use the high-quality DAC

With FiiO devices so far, all sound is processed inside the dedicated DAC and there is no SoC DAC, so there is no physical way to process sonic information unless it is going through the ESS chip.

Haven't hear anything about DP-X1 before, but tested X5-3 and the sound is indeed processed in the dedicated DAC for all third part apps, same for the original X7 as far as I can tell.

Hey all, I'm looking for a new DAP and was just reading about this one. Is there any word on price or release date yet? Can't find anything online
