Just curious, is anyone able to hear a difference between DSP on versus DSP off? I'm using an extremely early version of the DP-X1 firmware and there is quite a stark difference with DSP on vs DSP off. DSP on would give me more sound decay and detailing, but less obvious instrumental separation.

I always set it off as it makes the sound "thinner"
 
I'm using the latest FW BTW

for better battery life, after a hearing and better turn off the dp or put on standby?

Use Stand Alone mode.

Yeah I had the same experience too.
 
Turning on DSP seems to isolate the frequencies, but it reduces the amount of detail and sound decay. Like you mentioned, it thins the sound. The DP-X1 seems to sound richer with DSP turned off.
 
I found this article too, which mentioned that it is less resolving when DSP is turned on. The article article also goes on to mention how DSP colours the sound and turning DSP off improves "the contour" (sorry I was using Google Translate to translate the page) of the sound.

could someone who understands japanese help to explain this article? Google Translate only does so much.

I found that leaving it permanently in Flight/Airplane Mode improved the standby time (battery drain) quite drastically.

+1 FOR THIS

My feeling with dsp a 192 is that sound spreads but did not notice loss of detail.

 

[joven2468]

Yeah I agree. I feel that the loss of detail comes when the piece of detail that you are looking at lies in that "spread" that you've mentioned. When the sound tightens, the sound artefacts found in that particular region becomes less apparent, hence the impression that there is a loss of detail. Its somewhat like a loss of airiness and sound decay. Like its been either compressed or chopped off.
 
Maybe that's why people feel that the DP-X1 sounds thin, because DSP is tuned on by default when you first use the DP-X1

DSP is only for the default player right?

The longest that I've used my DP-X1 was for 6-7 hours straight (I was doing work on my laptop, whilst enjoying music), on the regular Balanced Mode. (DSP off). By then, I had around 35%-30% battery left.
 
I'm using the firmware that I bought it at, and have not upgraded my firmware. Its working fine. Won't want to fix what's not broken.

yes, I believe so. only for the native player. DSP can either be turned on or off. When you turn on your DP-X1 for the first time, it is set to ON by default I think.

ohh ok thanks!

 

[cirodts]

dsp and therefore not recommended

Anyone know how to delete a song from Onkyo player while playing? (Not connected to CPU or laptop)
