So, I've had the DS2 for a bit now, and quite pleased with it. https://www.fosiaudio.com/product/dac/headphone-amplifier/ds2 It's well constructed, with a understated design in the charcoal grey model. It's got a high and low gain switch, which I found useful, and the PR2 sounds noticeably...

Now that my fascination with the PR2 has faded somewhat - I still find it to be a brilliant IEM - I decided to give my trusty ZAX a workout. It's just as good as I recall, after some correction EQ is applied that is, and I'm very happy to own it still. Speaking of ZAX correction EQ, here's...

Another mistake you've made is only looking at the required voltage part of the calculation. By the way, both of my portable DAC-AMP dongles are capable of far higher voltages. While voltage is essential, the more important things here are milliwatts and amperage. My portables aren't lacking in...

You're assuming I've not driven it already with a variety of amplification. However, you're incorrect in that. I've driven it with all manner of amplification, including desktop amplifiers and the 3.5mm output of computers. I'm fine.

Yeah, the reality is quite different, and I've no interest in permanent hearing damage. The power required for V1 under its most challenging load: The load parameters as per KZ themselves:

1W? These aren't speakers. I own a V1 and I'm driving it very satisfactorily with the following: https://hifigo.com/products/jcally-jm6-pro https://whizzer.store/product/import-placeholder-for-882/

You've just lost your bet. I'll PM my bank account details to you for payment. I'm listening to Classical at the moment, with a Jcally JM6 Pro and PR2 v1, and violins, cellos and piano sound just lovely... 🎻🤵🏾‍♂️ 🎤⚡🗼🌌🗼⚡📱⚡🎧🎶🎶 😎

"Why would you kill the treble air of the PR2 lol." @seanwee Since you've neither my PR2 nor HRTF in your possession, you couldn't possibly assess that with any real confidence. So, back on ignore you go, you silly twit... 😜

"Unfortunately I don't think it's possible to globally EQ these because they are very inconsistent unit to unit." With the PR2 v2's frequency response now being controlled entirely by electronics and a nozzle filter, unit variation will be reduced to an absolute minimum. PR2 v1 would exhibit...

I'd suggest properly EQing the PR2 to accommodate your anatomy (i.e. HRTF) and preference before wasting money on another hardware component. The 9038S is more than powerful enough to deafen you as is. Something as simple as a poor seal of the eartips can throw frequency response all over the...

I find it curious that the PR2 would struggle with that DAC-AMP dongle, because of the following - this was taken from its product page: I've driven it with a 1.6Vrms DAC-AMP dongle that'll push 60mW into 32 Ohms/7.4mW into 600 Ohms, and it'll drive it to a very high volume level. However, I...

Just a new PR2 EQ profile for your consideration. I built it a few hours ago, have been listening with it since, and believe it's more tonally balanced and neutral. I based the EQ profile upon Paul Wasabii's measurements for the Crinacle Zero:Red and the PR2, and the Harman IE 2019 target. My...

I'd much rather look like an idiot than come across as an impolite, arrogant, rude dick lacking in social graces any day... 😝

Have it your way, not that I care... 😆

Well, you've measurements to examine now, don't you? We rarely, if ever, see that from the talking heads on YouTube.

Well, that's probably why I took the time to mention the milliwatts into Ohms figures. But feel free to overlook that.

I think I was a person responsible for initially promoting the JM6 Pro as a good match for the PR2; I run my mouth quite a bit on audio related social media channels. Yes, I did notice an improvement with it over the 1Vrms Apple dongle. The sound is more open, dynamic and impactful with the...

Another DAC-AMP dongle for your hungry PR2 to consider: Whizzer DA1: Review and measurements Its performance, features and construction are excellent for the price of ~$30USD. I've decided to order one for myself just because I can... 🤪 Re: PR2 driver flex I'm not experiencing it. However...

I've been refining my PR2 EQ profile to better match the tonal balance of my Harman developed speakers. I believe this is much closer to my goal. YMMV

My own EQ settings for the PR2. It's calculateed from Paul Wasabii's measurements and based upon Harman 2019 v2 with the upper midrange and presence regions reduced by - 2.5 dB [edit] on a slope starting at 1.6Khz. My goal was to more closely align with the tonal balance of my Harman developed...

Re: EQ Profiles Since we've been talking EQ profiles recently, I thought this might be useful to those of you who might be running Logitech Media Server and wish to incorporate your KZ IEMs into that environment. It's applicable to other other IEMs, headphones and speakers as well...

I thought this might be useful to those of you who run Logitech Media Server for your music streaming needs. There's a new DSP plug-in being developed for it, SqueezeDSP. While it is still in the developement phase, it's stable and usable for all but the more complex setups. As a matter of...

Yes, it's quite similar to my own.
