@deer_creek_audio Thank you for the DSP/RC recommendation. I had been experimenting with Wiim RC/PEQ to boost the missing low end, but since the arrival of the two sub-$1k DACs, the bass has really come alive. I want to get an external mic. to get more accurate SPL measurement for my room though.
Walk-in soundstage
Coupled with his Weiss DAC 204 and T+A DAC 200, Mr. Steve Huff claimed to have experienced the so-called "walk-in soundstage" when using the Lumin U2 as the streaming transporter. This refers to a deeply immersive, three-dimensional stereo image where the listener perceives the musical space as so realistic and spacious that it feels as if one could physically walk into the soundstage.
This level of presentation is notably different from the more common “layered” sound field that many average listeners or reviewers report—where the sound is merely projected in front of the listener with some layering or spatial envelopment.
I'm curious how many of you have also experienced this effect in your own systems and listening spaces. If you're open to sharing, I'd love to hear about the components and setup that helped you achieve it.

@richardbrand Thank you for letting me know about the various improvements Quad has made to enhance the performance of the ESL, such as increased volume and improved bass. Has there been any discussion regarding the treble roll-off above 10 kHz (as seen in the ESL 2805)? I’ve never seen a roll-off quite like that.

Geez, people still paying attention to Steve Huff? The guys a grifter and fraud. Makes a living talking to the dead with his spirit box, or whatever he calls it. I like seeing different gear almost as much as the next guy but can’t stomach Huff. He should be ashamed of himself. |
If you want to read someone who know a bit much than gear name and price and "colors" read Dr. Edgar Choueiri articles and youtube videos and you will understand why audio is not about electronical design first but about physical acoustics and psycho-acoustics... And you will understand why even honest reviewers miss the main point about audio...
I am interested by theoretical acoustics because speech mystery, hearing mystery, are key to understand audio but especially ourselves as beings ... https://www.theoretica.us/References/Immersive_Sound_(Excerpts_from_Chapter_5).pdf

This is about the crosstalk cancellation (XTC) algorithm implemented in BACCH. Thanks for sharing. If the XTC-induced tonal distortion during playback with only two loudspeakers is the main factor affecting the perceived 3D sound effect, would reducing crosstalk (XT) be the ultimate solution? If so, one could use two mono amplifiers or a true dual-mono amplifier to greatly reduce crosstalk and enhance stereo imaging. However, complete elimination of XT is not necessarily beneficial. If the sound reproduction had no crosstalk, as in pure binaural audio fed into headphones without processing, the outcome can be unnaturally wide or even disorienting. Simply put, our ears are accustomed to some crosstalk in real life—sound from the left still reaches the right ear, and vice versa. From this excellent article, I am not sure how Professor Choueiri addresses this aspect in an optimal way. In addition to the aforementioned electrical XT, there is also acoustic crosstalk to consider. I have already addressed this with speaker separation, toe-in adjustment, room treatment (in process), and reflection control. Beyond that, it seems the use of digital filters such as BACCH will be the route but what else? |
