Tomorrow I'm going to buy a second hand micro idsd, any faulties that I should check?

Sure, anytime!

Sorry for quote, but could u answer this question, I'm gonna buy it in hours

None that I'm aware of. Just connect it via USB, rock some music you know well, possibly try several formats, and if there's nothing that seems odd go for it!

Works like a charm.

Update firmware to play mqa (cookies & cream), and so surprise of quality and the powerful that this dac is. It capable of move my hungers akg 612 in eco mode.

Really happy with the purchase!!

I'm glad you like it, but just to clarify: you got the Black Label, or silver micro iDSD?

Silver micro

For the iDSD micro, the different power modes do not change either output impedance / damping factor (damping factor is load impedance divided by output impedance). Neither does the current limit of the circuit change.

The output impedance / damping factor and current limit change only if iEMatch is engaged.

The lower power is simply due to reducing the power supply voltage and the circuit gain, thus making the amplifier clip earlier but also consuming much less idle power.

The largest objective change we observe is that the higher gain / power modes have marginally higher distortion levels into low impedance headphones (< 50 Ohm) and absolute background noise is raised in line with gain.

So, objectively the higher gain/power modes produce more background noise, a smidgen more distortion and the amplifier clips at higher output voltage levels.

What this means is that the higher gain/power are matched to higher impedance, lower sensitivity headphones. In this case the distortion remains low and the noise at the actual headphone accoustic output also remains low and the added output voltage compensates the lower sensitivity.

We would not wish to venture speculations as to why some iDSD micro users perceive large sonic differences with power mode.

However our own listening panels (using multiple iDSD micro accurately level matched) did not pick up on these differences and which show no evidence in measured performance.

It is essential to make sure to adjust the volume setting using a test signal and a suitable signal meter to compensate gain changes, rather than attempting to level match "by ear".

As little as an 0.5dB higher level (and 0.5dB are near impossible to set accurately and repeatedly by ear) will give a sound that is subjectively perceived as more dynamic and possibly with more bass, but is not perceived as louder.

It takes around 3dB level difference before the louder source is identified as louder using music, so it is relatively easy to be fooled by small but significant level differences into "hearing things" that in reality do not exist.

I ran across this very useful post while researching whether it's theoretically better to run my BL in Eco with volume knob at 11:00-12;00 or Normal mode with volume knob closer to 9:00 (which is on the brink of channel imbalance). This post clears that up, thank you!

There was another post by iFi earlier in the thread that states optimal performance is between 12:00-3:00 on the volume knob. But I can't get to that position with any of my headohones (none are IEMs), unless I engage IE Match. And since there are real changes to the amping specs when doing that, am i correct to assume it's theoretically better to dwell below 12:00 on the volume knob than it is to engage IE Match in order to get the knob nearer to 3:00?

Noting that the IEMatch components also need to burn in so you would need to run with it for a while in that mode to hear it at its best .

Firmware 5.3 cookies and cream installed. WIndows 10 Pro
When I plug in the DAC always light on yellow... Why is that? Im not playing any file and it goes yellow...

What happens with that yellow LED when you play any music?

True!

Remember. Whether you have the idsd in eco, normal or turbo, according to ifi, the listening volume should be between 12:00 and 3:00.

I can't get above 12:00 with any of my headphones, even in Eco (all full size over ear). So is it better, in theory, to dwell below 12:00 or to switch on IEMatch in order to get up into the 12:00-3:00 range?
