Hi, I'm a new user and purchased the DAC+ DSP in order to have a room EQ in a room already with some room treatment, but suffering still from a little bit of room reflections and some modes.
Since the product was quite inexpensive compared to any hifi product, and especially considering the scale of things, I thought I would try to contribute by writing my fresh user experience.
I am using the Lyngdorf TDAI2200 with digital input and BW 805 Diamond speakers.
The room is about 7x5x3 meters.
I think the wizard was great and intuitive, and not only that but it worked every time, except the first, where it would give me an error because a DSP program was not installed. Was easy enough to fix, but maybe this could be done automatically on first boot as to not confuse the user? Before this was done there was a lot of loud bangs and pops all the time.
There is still a loud pop whenever the device boots, and also when it starts and stop the sweep sound in the Room Eq test.
There was a warning about the loudness of the test, but the loudest part was really the pink noise in the beginning, maybe that could be altered to something that would still do the job but is less annoying.
After the test, I would love for it to give me some insights. The most important is being able to accurately look at the measured frequency response and see at which exact frequencies are dips and peaks, and at what dB.
I didn't get a good result at all after the initial calibration, it sounded muddy and flat at the same time. I think a lot of that was due to my speaker placement, because my right channel was near a room corner, while the left is more in the middle of the room. There was no individual channel equalization as far as I can see, and that's the biggest missing thing right now in my point of view.
Could it do four measurements of each of the channels, then if they are quite similar combine the eq, otherwise suggest to use split equalization?
Tweaking the frequency response curve was hard, due to the fact that I couldn't accurately see what had been measured, only graphically, and that I needed to go back and forth between the Room Eq and Parametric Eq screens constantly to check, since it wasn't possible to overlay it.
Here is an example of a near field listening position which had a lot of boomyness to it, but I thought would be able to be tamed with EQ. It absolutely did and it was a great success. I simply disabled the compensation of the high frequency bump to give the speakers back their characteristic, and it sounds great, much better than without the filter.
After this I added a little bass bump on the user eq, since the speakers are shelf speakers and the room is big. It's nice that these things are separated. First fixing it, before changing it.
As a sanity check, I used the listening mode 'joystick' and it definitely does sound more neutral in the middle position than all the others.
