Forget the blatant problems with Dirac .. and tone controls and eq
edited: because not thinking.With around -60dB (0.1%) at 500Hz, 1.5kHz, 2.5kHz and so on ?
It might be.
Masking effect is small on such IMD distortion, to my knowledge.
Might be worth a blind test, for once.
Just running the test signal (which you probably won't hear) and listening to the residual, maybe ?
(Be carefully not to fry your tweeter, though.)
Try the same with bass control -0.5dB, please.112.0 dB SINAD with tone controls on
(-6 dBFS penalty for tone controls)
You'll see something interesting...

Wow, that's great and that's how my M33 does it too
There is probably enough DSP power for DLART

It's rather 20dB SINAD penalty, isn't it ?95.3 dB SINAD with Dirac On
(-10 dBFS penalty for Dirac)
Dirac Live works with 192 kHz!
Or do you mean the level is 10dB lower ?
Nice to read it runs at 192kHz.

Level is about 4dB lower from the rest as far as I see.

I would add a measurement down to 40-50Hz with Dirac on,or a Multitone.
No, just bass control
Sorry meant how bad would it be if we used both ?
Here is what this gives me on the Node N132.
Just Tone control on and -0.5dB Bass.
Just Tone control on and -0.5dB Bass.
Well, try both.

Who uses this when you have the option of multiple Dirac Live presets
People who didn't purchase Dirac ?Who uses this when you have the option of multiple Dirac Live presets
People who want to temporarily apply some bass correction on a specific track ?
People who are listening at low volume ?
...
This issue is common to all Bluesound models.

I cannot imagine who should not use this outstanding feature
You may count me as one.I cannot imagine who should not use this outstanding feature
I have currently quite a few Node N100, PowerNode N150, NAD M50 and now Node N132.
I use a miniDSP Dirac with the M50.
I plan to use Dirac with the N132.
But the other ones will remain without it.
Even if it was technically supported on the first generation devices (it's not) I can't justify the spent in the kitchen, in my office (using mostly headphones - or old Genelec through a RME UFX III), or in my wife's painter workshop.

Ok. Will try tomorrow.
At 0 dBFS source, my E1DA has about 3 dB headroom. Enabling tone controls means you get a maximum of -6 dBFS for a source file of 0 dBFS and enabling Dirac reserves 10 dBFS (maybe 10.5 dB actually)
Yes, SINAD hits lower.
This first round of Dirac testing is with a real world measurement so the 40-50 Hz measurement will be affected by the correction. I will need to find out what sample rate Dirac is running at when you calibrate and will see if I can trick it into letting me use my SPDIF input as a recorder to create that mythical digital flat. THEN, you would be able to do crazy tone controls for the headphone out of the Node Icon
While my Node Icon does great for XLR out, I only got 81.9 dB with Dirac on (with a real correction file in use) so it may very well be a huge RCA penalty that you see also seeing. But I will try this tomorrow if I have time.
Honestly, I might return Dirac since the raw performance is so good. The correction you see is just a single point measurement for testing purposes, but with multiple measurements across the actual multi-person social listening area, the actual bass response in the room averages out differently. My speakers are phase coherent which may also decrease the subjective benefits.I cannot imagine who should not use this outstanding feature
That said, I can see people buying the Node Icon with no concept of audio quality but just wanting the LCD display. Those customers are probably not too concerned about SINAD though.
Actually even if you use room correction Dirac or otherwise, you want normal tone controls for quick corrections of the played material

That could be audible through a lot of headphone setups, definitely. I've mentioned my liking of music like solo classical guitar in the vinyl renaissance thread in light of my experience that it doesn't mask as well as other music, and it would apply here as well. Would the Icon be used for headphone listening though? Maybe for people who decide to believe in QRONO...
I'm considering the Icon, not just as a streamer but also as DAC, preamp and headphone amp. I would occasionally use it in a studio setting so latency is important. I can't find any info on what the latency in local (don't care about multiroom) scenarios is, with and without Dirac enabled. Obviously, the lower the latency, the better. Anyone here knows what the latency is?
