I can't recommend any brands or models, but I do have certain preferences when it comes to closed headphones. Namely, they need to do 32 Ohms with ease, have a range of 5 Hz to 25kHz, roughly 110-120 decible resonance(?), and preferably with greater than one meter worth of cord. (Also helps of the cord is detachable and single sided.) And that's about my two cents.

Don't get hung up on response being listed "5Hz to 25kHz"... there is almost no musical content below 18hz ( organ music) and the low end spec for Dolby Atmos is 31.5 Hz so movies will also not have much if anything below that spec. The other spec's you are referring to appear to be nominal impedance and sensitivity. These can be a measure of how difficult to drive a headphone is but really only scratch the surface until you take into account your amplification source and the full impedance curve of the headphone.

Huh, strange. I did once own a pair of headphones that had a listed sensitivity of 8Hz-20kHz. I could defenitely hear the lower end frequenices. Maybe that's just me, IDK. The way I test most headphones/IEMs is to play 311's "T&P Combo." The refrain has a bass line that runs up and down the scale. Most headphones I've used that have a sensitivity of 15 Hz-20kHz miss out on the bottom end of the scale. Very few with a sensitivity of 10 Hz-20kHz can reach the lowest end fo the scale. Only that 8 Hz set of 'phones was able to reach the highest and lowest end of the bass line. I prefer my gear to reach as high and as low as possible technology can allow. IDK if that makes me an audiophile or headphone expert, that's just what I prefer.

Well human hearing doesn't go bellow 20hz so even if the headphones can do it you really can't hear those very low frequencies. You can feel ultra low frequencies but not sure if headphones can do that (speakers can)

A frequency response spec without a variance (+/-) listed is borderline meaning less. A headphone that states (5hz to 25khz) could be 20db down from nominal at either end of that spectrum (roughly 1/4 perceived output to the other frequencies). A different headphone rated 25hz to 20khz +/- 3db is much more informative. You know that you will be no more than 6 db's down from peak at any one frequency. In your "8hz" example the headphone you're are talking about more than likely had a much slower roll off on the bass frequencies than what you were comparing it to (a lower +/- variance).
Sensitivity - the volume produced at a given power level at a given frequency response (typically 1khz) Nominal Impedance - the baseline resistance a headphone displays to the flow of electrical current from a source. Low impedance requires more current, high impedance requires more voltage from your souce Frequency Response - the range of frequencies a headphone can produce, most valuable when displayed in graphic form or with a tolerance/variance attached.

Drop should make a DT88X
Throughout my time as an audiophile I've read quite a lot of positive reviews regarding the DT880 Pro, especially the 600 ohms version, I've seen it being highly praised for it's build quality, comfort and sound, however there is one fault I'd point out: no removable cables. As much as the DT880 Pro is marketed towards professional usage ( at least that's what I think, given the "Pro" in it's name ) it is adored by the audiophile community, thus I'd love to see a more audio-enthusiast focused version which only difference would be having a removable cable with a 3.5mm connector on each cup. I reckon the benefits would be quite sizeable : you wouldn't be confined to the 3m cable of the original version; it'd possible to run it balanced (which would help with the endeavour of properly amplifying the 600 ohms version); should the cable fail due to an accident or the throes of time dealing with it would be much simpler and , finally, if you are part of Team...

How to connect my laptop to DROP + THX AAA™ 789 LINEAR AMPLIFIER
I have the Focal Elex. I plug it into the mini plug audio output on my HP laptop and listen to Youtube music, and some Wav tracks saved on my computer. How do I connect the following unit into my laptop to improve my listening experience? Do I need a special cable that goes from my laptop into the DROP + THX AAA™ 789 LINEAR AMPLIFIER ?

The upcoming Drop HD 800 in the works vs my existing Drop Focal Elex
I'm very interested in the upcoming custom Drop HD 800 https://drop.com/buy/drop-sennheiser-hd-8xx-headphones#overview. I'm aware some noted mastering houses use the older HD 800(S?) so that peaks my interest in them. It seems the Senn is sometimes used to identify any treble artifacts in tracks. I currently use the Elex, and I really like the relaxed, fairly accurate sound. 10 months of use now, and I just had the left driver fail. Drop is sending another new set as I type. I feel like I'm dealing with a finicky product with the Elex, and that is a drag, but the sound is working and I enjoy them. Oluv, on Youtube, compared the Elex and the HD 800S. The Elex was better in some ways, though some felt otherwise. I guess I could sell the Elex if the Drop HD 800 smokes it. I see that I can return the Drop HD 800 if I don't like it, so I just ordered it. Shipping in November 2021.

CTH + SDAC is on the fritz. Can someone help?
So I've been using my CTH + SDAC for a couple years with no problems. However, within the last month or so, I've been running into a few issues: some hissing in the right channel (which is only really audible at 0 volume) and sometimes there are clicking sounds from the box during which the sound cuts out. It seems like it's struggling to stay fully active for some reason. I just bought a replacement 6922 tube to see if that would fix the issue. It seems to have solved the hissing, but there's still intermittent clicks that cut the audio. It's the same clicking sound that happens when the unit's LED changes from red to white and allows audio through during normal operation, but it will happen repeatedly and quickly in succession, without the LED changing, and the audio will go in and out. Has anyone had this issue or know what's going on?
