Here is the step response of the Nubert nuVero 140 in my room (that is a 3.5-way ported speaker) You can see that the drivers are separated in time (the peaks and dips within the first 1ms) And the same using Dirac Live (I believe 2.x at that time, this was 3 years ago) - now the drivers are...

Well, in that case I guess this is not going to be possible If you want to use REW-generated filters in any device you will need either PEQ capability (ideally per channel) or convolution capability (so you could load the convolution wav file generated in REW into the convolution engine of the...

Are you using Wiim Pro? If it has a Parametric EQ (PEQ) then you can just enter the REW-generated EQ filters there

This is actually really interesting As far as I know PWM and DSD signals are not that far away from each other One could actually use Jriver for example to convert and output DSD in real-time to an FDA that could accept DSD signal and amplify it directly (if that is possible....) This might...

An FDA is essentially a class D amp. The difference is that while a conventional class D amp's signal path will look like this: analog input --> PWM conversion and amplification --> PWM to analog conversion at the output stage using a low-pass filter (and for this to work with a digital source...

Check out his review on the SMSL A2 amp, basically it is the same as the Sabaj A30A https://www.audiosciencereview.com/forum/index.php?threads/smsl-vmv-a2-review-stereo-amplifier-dac.24640/

And finally, some videos: https://photos.app.goo.gl/2aWdsQ1bwCDn5ZTXA Enjoy! :)

I have been playing around with Voicemeeter Banana (again) to try to use one stereo USB device (A1 in Banana) for the front channels and another stereo USB device (A2) for the rear channels and it works like a charm However there is an issue that actually renders is totally useless: whenever...

sorry I missed 'Connect', I just use the Tidal Desktop App and the WDM driver of Jriver to use Jriver's DSP engine on Tidal

Jriver - love it!

And with the paintjob done I consider this project to be finished:

Amazing! I have three of them, one is driving my system in my home office and two others are driving my living room 4.0 system (here and here) I can still confirm that I have never heard anything more detailed and precise like this - I am totally blown away Eager to wait for the next generation...

Just bumped into this product released today: https://www.audiophonics.fr/en/interface-modules/audiophonics-digirescue-reclocker-module-spdif-optical-coaxial-galvanic-insulation-24bit-192khz-p-17813.html Could this have any audible improvement or is this just yet another variant of snake oil...

Just a recent update on this topic: I have tried a purely linear phase approach (=low-pass filter on the rears and all shelf filters on all channels are linear phase using 12dB/octave slope) and actually that sounds the best so far! It measures a bit worse than the previous approach but by ear...

AFAIK, no But I recommend asking Dirac about it, just to make sure

Just FYI sharing this here too: https://www.audiosciencereview.com/forum/index.php?threads/homebrew-dirac-art.43789/#post-1558141 I will spend a bit more time with the concept in the coming weeks I hope that the real Dirac ART will even be better and that it will be available on a PC...

Hi @ElliotA Yes, they are all available

Just realized that I forgot to add the phase graph:

The Morels were by far the worst The CHR120s were way better than the Morels and the SBs are so far the best And price-wise we are going waaaay down ;) Apparently price has really nothing to do with quality here...

The paint-job is still to be done, here is where I am now: And the measurements: Left channel, MLP measurement from approx. 75cm at 75dB Corrected with Dirac Live 3.6 (highlighted) vs uncorrected Distortion is room-driven due to the dips (I tried these drivers in my other room, distortion...
