Hello, pardon me if it’s an easy answer but I can’t seem to find and an answer to the purpose of two DACs in the m9. Also q5 I think has the same.


Are they for left and right in the balanced port or do they both play a roll even with the unbalanced 3.5 port or is just one utilized for the 3.5 out.


Also, if you happen to know, why we can only use “turbo mode” to create more power on the balanced output and not the unbalanced output.


This particular question is what what makes me think that the dual DACs are only both in use on balanced 2.5 output.


Does this sound logical or cal or am I way off please.


I just want want to fully understand the benefit as it may play into wether I get a balanced cable for hd650 or not. They are kind of expensive but the power increase sounds interesting. I could just use my a5 but I like to understand the pros and cons.


Thanks

I would be very surprised if both DAC chip are not used (one for right channel, one for left channel) for both the balanced and un-balanced ports.

There are actually a lot of CDPs and DACs/DAC-HPamps that have two DACs working each channel despite single ended output. Whether that actually increases channel separation is debatable.

Now for a circuit that can also operate as a balanced output or balanced drive on headphones it's easier to get a truly balanced analogue signal through and through since you have two separate DAC chips already. In this case it isn't simply whether using one DAC for each channel helps channel separation but it makes running balanced mode easier if you use it that way.

You can assume that both are working even in SE output mode (again, debatable) since it's easier to just run the CPU to split the channels into each DAC regardless of whether you're using SE or balanced.

Also, if you happen to know, why we can only use “turbo mode” to create more power on the balanced output and not the unbalanced output.

Chances are since the circuit is primarily designed for balanced operation and has SE mode only so it will sell easier since people who don't want to buy balanced cables can also use it they see no point in having a turbo mode for SE given that users who want more power should just get a balanced cable anyway. It's probably harder to do for the SE mode unless the whole circuit was done just in SE.

I wouldn't expect a lot of improvements from that though especially if turbo mode increases noise, unless you can get the balanced cables cheap. Like the generic ones on Amazon.

Thanks for the info. It sounds pretty logical and on point. You make a good point a turbo mode noise. I was thinking that too.

Thanks for replying.
