You can use all the outputs at the same time with no issues - We actually tried it at a local meet. Always fun to see a DAP feeding two DAC's, an amp and two sets of cans at the same time biggrin.gif

Lol how was the sound quality when powering 5 things?

In the end, after testing a few other speakers I think the bottom line is that the N804 or B&W's 800 series (i.e. the Diamonds) aren't just my taste (or my taste has changed after 12 years). The Franco Serblin Accordos and Sonus Faber Guarneri Evolution look mighty nice though!

 

Woops...drifting from the topic. Apologies all. Happy to take this to PM with ya, spkrs01.

I'm not so sure. I figure it would be ok though as long as they are the same IEM.

Both the 1/4" and 1/8" headphone outputs of the DX100 are wired in parallel. There are no additional resistors or any other devices to "protect" phones plugged into the 1/8" output. Adding 2 sets of headphones will result in the DX100 seeing an impedance that is different from that of either headphone. This new impedance will always be lower than that of the lowest headphone. This may or may not result in audible differences. Here is a simple calculator that will determine the resistance of multiple parallel headphones. (note that in actual use, the impedance can vary from that specified for your phones and is not a simple resistance measurement)

The phones can also affect each other a bit with debatable back EMF and added reactance besides just impedance. Best to drive one at a time.

I've had the opposite happen. Going from a lo-res to a hi-res track causes it to play at half speed. So far it has only happened once and just changing the track again fixed it. Although a bit disconcerting at first, it's not that big of a problem. And considering the leading-edge nature of the DX100, I'm willing to let it slide.

I still like well done horn speakers. I have some highly modified Klipsch speakers in storage that are heaven for me. Sadly, they have not seen the light of a listening room for a long time.

This seems very basic to me, I'm surprised that iBasso did things the way they did.  Or was it Rockchip?

It really does not matter. :)

 

As long as the fixes come.

 

THis is the same exact issue from before where the "Greatest hits" albums where gettings clustereed together...

How does SRC work?  i know you can upsample to your bit of choice. But if i set it to 24Bit 192 will it bring out better sound quality ?

No

 

all it does is upsample anything that is not that rate. The ESS still resets on read and still has the lead in fade.

This is a question for the computer guys out there:  why is it that the 1.2.7 upgrade has improved the sound quality so drastically?  I had always assumed that sound improvements were a matter of hardware, not software.. does this mean that the next software upgrade could improve the SQ even further?

they muck with the default EQ setting. Nothing wrong with that. That is why when you turn the EQ on there is about a 3db drop across the board.

 

1.2.3 chaned CLK freq of the dsp.they fixed in 1.2.7

My question is , if I use one of the digital outputs // coax or optical
Is the software / eq affected by the software or do I just get the music before DAC
And u layered ??

With the DX100 the changes are made in the digital domain (actually that is a big benefit) so you can even EQ the signal. I've done it before even with Coaxil and toslink.

In the 1.2.3 firmware they were actually handling the voltage to the Sabre DAC slightly different, so the SQ suffered. Try downloading and applying that update (totally reversible), then listen for the bass to come all lose and sloppy smile.gif

 

Oh and when I say "all lose and sloppy", it's still better than most DAP's out there, but not very good by DX100 standards.
