    Most of my music is also provenant from CDs but I have a handful of high resolution downloads. This evening I'll run them through Spek

    Run a sample of your favourite recordings (if they are in High Res, Redbook and vinyl/tape don't do 20kHz+) through a spectrogram analyser and tell me how many of them have any energy above -60dB from 25kHz onwards. If it's not in the recording, end of. . Lot's of system have mild to severe problems in the audible range and yet people worry about ultrasonics.

    They may be better but beaming at high-mid and high frequencies, high-frequency distortion, intermodulation distortion, none of that has changed.

    Yes, which is why the question is meaningless because the classification of "musical" is personal / not universal.

    You can try the "mosquito" but be gentle on the volume; my kids flew screaming out the room... https://www.audiocheck.net/audiotests_mosquito.php https://www.audiocheck.net/audiotests_frequencycheckhigh.php

    What if, and it's a big if, my musical is not your musical is not @complin musical is not etc.?

    See previous post regarding instrument frequency range, microphone frequency range and tweeters: https://hifiwigwam.com/forum/topic/130058-facts-vs-myths/?do=findComment&comment=2308978 Also one can easily argue that instruments developped through time to sound beautiful in the audible range. Same with music. Finally, it's been argued over and over that add-on supertweeters can be heard because they produce sound below the high frequency threshold of hearing.

    Ultrasonic frequencies are important in reproduction in regards to digital audio (affects filtering), to amplification (affects wide-bandwidth) and to speakers (affects hard-dome tweeter breakup resonances) Ultrasonic frequencies are not important for listeners because we can't hear them, many tweeters breakup with a bang between 20 and 30kHz, hardly any instruments produce fundamental notes that go beyond the audible range, harmonics of most instruments are very low in level or non-existing above 20kHz, no composer/writer that I know of has ever composed ultrasonic music, most mics roll-off at or sometimes before 20kHz, well recorded classical music uses distant mic'ing which rolls-off treble naturally. This is the close-mic'ed frequency response of a trumpet w/ wah-wah: https://www.cco.caltech.edu/~boyk/spectra/spectra.htm Note how the harmonics are more than 37.5dB down in level at 30kHz. . In my opinion, sub-bass frequencies (<60Hz) are far more important because in classical music recordings at least they're responsible for conveying the ambience of the original venue.

    That settles it then, we're all in agreement.

    Thanks. Your post saved me from a lot of writing. I'd add that: Perhaps regarding subs it depends. Aren't PSUs part of the amplifier circuit? There are good and bad things in all speaker topologies but single drivers have the least performance potential of them all.

    Dali speakers are designed for zero toe-in (they're flattest at around 10-20º, and still a bit bright), so I wouldn't recommend them for short-wall positioning. Otherwise

    More toe-in improves focusing but reduces the soundstage effect, which is a product of room reflections. See here: phantom images.pdf It also increases top-end energy because tweeters become more directional as the frequency rises. Room reflections also change the tonal balance reaching the listening spot, which is why the frequency response of loudspeakers should be smooth off-axis.

    This. Awful-sounding speakers. One of the worst I listened to was a pair of PL100s...
