Thank you all for your replies and for helping out a newcomer; I really appreciate it!
You do need a lot more power if you plan to use PEQ.
I like the stock sound of v2, I love it with PEQ.
Can you share your PEQ settings? Apologies if you've already done so, in which case a link would suffice
With +6db Gain on all frequencies ( which doubles the voltage swing) it becomes 4.2V. Your +6db is bass boost so it definitely won't go beyond 4.2V
I see, that is good to know.
Some more info about the PEQ settings: I was simply using the crinacle profile provided by autoeq (which has a +6dB by default I believe) whose values I added to Hiby music player's PEQ and saved as a profile. Attached is the profile used (I did not change any of the advanced settings). I tried out various profiles, including those posted on various forums and messing with the bass boost to 4.5dB and 2dB, but I liked the stock Crinacle profile the best
G5 will not clip at all even at 6V. There's no possibility it cannot deliver enough power at 4.2V.
Got it, thanks for confirming!
I am not able to answer that question. To me there's enough bass even if I don't boost it at all, and the bass is ultra clear. The drum sound has very clear impulse and starts/stops right at the point. My Sennheiser is not able to do that. and that's the happiest experience I have with this headphone.
I don't even need to use an external amplifier to achieve that. My MacBook Pro can already drive that to very loud levels, though not painful level, when I max the system volume. Your G5 is much powerful than my MacBook Pro. (MacBook Pro max at 1Vrms. With a fake 300Ohm resistor we can make it achieve 1.6Vrms without clipping)
And I'm assuming the sound quality from the MBP and other sources, given the same volume level, is identical? I had the same experience with my earlier setup consisting of the HE400i with the Sonata HD Pro and a xDuoo MT-602. At the same volume level, I was unable to distinguish between the sound coming through purely the dongle compared to the dongle + amp.
I also tested the Apple dongle and the Sonata, and again, at the same volume level, there was no difference. So, I am inclined to agree that the source is not the issue after all.
Did you apply an appropriate preamp in HiBy?
Without that, you'll just run into digital clipping so your boost won't do anything.
I did apply the correct preamp levels.
This is how stuck magnets look. You can easily remove the grills (and put them back) and check under the light.
Also try using them without grills, that will affect the sound as well.
No, the magnets are not stuck. That was the first thing I checked after getting them actually. And I got a used pair which came with the grill mod already applied (with stock cushions).
----------------------------------------------------------
After mulling over things, changing more settings and most importantly, listening more, I think the issue was simply my expectations.
I still remember the first time I heard my music through proper headphones (Hifiman HE400i) back in 2020 and I was simply blown away. Coming from cheap $30 headphones and some 1More TWS buds, this was revolutionary and made me want to hear all my music again - it felt so, so good hearing everything in HD! I was able to pick out new details and everything felt so high quality, like going from 240p to FHD.
The upgrade to the Maxwell was much less noticeable. While it was all round better, it didn't have anywhere near the same wow factor as the previous upgrade. I would say it was akin to going from 24" FHD monitor to a 1440p 27" one - while clearly better and more pixel dense, not a night and day difference. I was hoping that the HE6SE would be something like going from a 27" 1440p monitor to a 27" 4k one, and recreate at least some of the experience of the joy and wonder I felt when upgrading to FHD (sorry for the analogy but I hope it makes sense). Instead, I think this was more like going to a 40" 4K display from the 27" 1440p quality of the Maxwell - clearly better yes, but just not as much as I was hoping it would be. Yes, I can hear significantly more details but it definitely did not blow my mind as much as I wanted it to ¯\_(ツ)_/¯ ; or maybe I will appreciate the qualities of this set more as my brain adjusts to it over time. I know it was the same with the HE400i when I put them on for the very first time and thinking "huh this isn't too different compared to other stuff," till I went back to my cheap headphones.
Of course, these are way better in terms of imaging and soundstage than the Audeze Maxwell, and so is the bass clarity and overall details. I guess I was just looking for an upgrade which would blow me away like earlier, which I suppose is simply not possible unless I spend thousands more, which I cannot do at the moment. Maybe some day
And lastly, if the Topping G5 is powering this correctly and to its full potential (which it most certainly is), I think I am happy with the sound (especially after going back and forth with my Truthear Hexa). While I will still be on the lookout to be able to try out an amp, I think I am good for now. I actually enjoy using the Topping G5 as a Bluetooth device (with 909/990kbps LDAC) more than I expected since I cannot detect a difference in quality. My only wish is for it to have on-device PEQ and playback+volume controls, but neither is too big a deal as I usually listen to around the house with my phone or at the workstation.
Once again, thank you all so much for reading and taking your time to reply. If I find out anything else or discover something new, I will be sure to report back. Until then, I'm gonna enjoy listening to music and picking out new details!
