MQA 16 bit 44,1 kHz super fast playback with integer mode on

[Malakhov645]

Hi! Haven’t found such topic, so posting here.

I’m using Cayin n3Pro as DAC (MQA full decoder), MacBook Pro as source, Tidal connected. So everything works fine, I’ve disabled all filters etc, enabled integer mode and enjoyed hi-res MQA perfect apart from 1 issue:

• with integer mode on , tracks from tidal which are sourced at 16 bit 44,1 kHz play super fast, only upsampling from 44,1 to 48 helps, but this kills MQA

• with integer mode off everything seems to be working perfect

My question is this - disabling integer mode off will affect MQA unfolding or no? In my case, with integer both on and off DAC shows correct source signal (24/44,1 or 24/48 every time it’s MQA)

Thanks

Try to disable integer mode.

Are you certain MQA works properly with integer off?

[bitracer]

Yes. I also have one device that behaves similarly.

What does integer mode do?

[bitracer]

It’s essentially the way the device (DAC in this case) is addressed.

[reddog1]

Sorry, didn’t quite understand that.
could you exsplain?

thanks.

[bitracer]

It’s interfacing thing, some DACs don’t work or work erroneously when in integer mode. That’s why you have a toggle there. It influences how the data is sent to the DAC.

When possible, keep the integer mode on. If it doesn’t work, toggle the integer mode to off.

ok… got that.
thanks.
