Yes, about -6db.

Here's what I'm currently using for EQ. My low bass is only about flat with these settings, maybe still slightly below. You could try these settings, but maybe raise #2 from +4.5db to +6.5db or so, this might give you enough low bass. Notice that #1 is cutting the very lowest bass off. This is...

That's what I recently found out with a Bryston bha-1 and HD600's, especially with a balanced cable to get all the power available. I was skeptical after reading how much they will scale, but it's true. I've owned and listened to several clearer and more detailed headphones, but after hearing...

I have HD600's and those Sony WF-1000XM4 as well. I also listen to some metal, as well as most other genres. Those earbuds do sound good. They still have lots of detail and clarity. I use the Headphones app and use some EQ to make them sound slightly more neutral. I also use EQ with the HD600's...

Oh ok, I didn't catch impedance.

Amp/source is Tidal streamed to Wiim Pro plus to bryston bha-1 and a balanced cable. I set my PEQ by looking at HD600 response graphs. Ended up having completely flat response except still 1 or 2db down on low bass instead of the stock 4 or 5db down. I also didn't raise that 3khz dip up to flat...

No bass spikes, just a 2db peak around 180hz. Starts climbing from 120hz up to 180, then back down to flat around 300.

The HD600's without EQ sound pretty good. But with a 3db boost around 30hz and tapering back to normal by 70hz, and bringing that 3khz or so peak down, is a huge improvement to me. They sound almost boring sometimes, but near perfect at the same time. Depends mostly on the recording, they can...

Audiophile Ninja has good quality pure copper cables that aren't expensive.

I don't have a bass shelf, didn't want to increase bass much further down than the 40hz peak. It's adding 3db of bass at 40hz and tapers down to flat again by 70hz. It adds some needed lower bass without adding any bloat to the mid bass.

I use a Wiim pro plus 4 band PEQ to fix the HD600 quirks/preferences. I adjusted them according to HD600 graphs, and it makes them sound amazing. One of the adjustments is a 3db peak at 40hz, not quite up to flat but a big improvement. If I had a 5th band, I'd use it cut bass off completely...

To add a little to this; My current system that I highly recommend is: Tidal hifi streamed from Samsung phone > Wiim pro plus > blue jeans rca's > bryston bha-1 > audiophile ninja balanced xlr cable(simple pure copper) > 2022 model HD600's(stock pads). Took some trial and error and "upgrades"...

I've never heard tube gear with headphones, but is supposed to be awesome with HD600's. I will if I get the chance, but with the results of my combo, along with the reliability and maintenance free aspect, I don't see myself switching.

I've owned LCD-3F with an RME adi-2 dac fs and had LCD-X on loan. The 3's were superior to the X, so I'll leave them out. The 3's have slightly better clarity than the HD600's, and had a bigger soundstage, but didn't sound as natural. That to me is where the 600's shine the most. My ears are...

I've owned and heard several higher end headphones. But after hearing the HD600's balanced from a bha-1 amp, I bought a second HD600, 2 extra cables and 4 extra earpads when they were all on sale. But also now have aftermarket 4.4 balanced and xlr cables as well.

Thanks, good to know it's that well designed.

The PEQ on the Wiim is only 4 band. I like the way I have it now, but if they can add 1 or more bands in the future, cutting the bass off below 20 or 25hz is exactly what I'd do.

I wasn't overly impressed with the BHA-1 at first, but I like it better after I started using a balanced cable. I'd like to try a BHCs someday if I can get one cheap, it's not the type of equipment I'd pay much money for. I would still also be using EQ with it, so not sure how much or any...

Spent some time setting up the WiiM pro plus 4 band parametric EQ for my 2022 model HD600's, using online measurements as a guide. I'm really liking the way this sounds, for several different genres of music. I don't have the bass boosted quite as much and have the most fatiguing 1-4 khz range...

The balanced cable allowed me to drop my phone volume from 90% down to about 65-70%. It may have also slightly added to detail, and did improve instrument separation. Loving this system.

I've now also added a balanced cable. Detail may have improved very slightly, and instrument separation did improve some. Very happy with this system.

I'm having the opposite gain problem on my newly acquired 2017 bha-1. Not a problem technically, I just want to keep the amp on low gain because I've read it has lower noise that way. Along with using the lower 1V recommended output for headphones from a Wiim pro plus, and not wanting to go over...

I highly recommend the Wiim pro plus/Bryston bha-1/hd600 combo. Most people aren't going to spend so much on a source and amp for HD600's, but it's awesome. I prefer it to the RME adi-2 dac fs/LCD-3F combo I had previously. I was using the hd600's first with a Fiio BTR7, using Tidal hifi with...

They look like the ones I bought in early 2018 and sold about 1.5 years ago. When I sold them they had very low hours on them, and were in mint condition other than the same peeling vinyl as those, although it wasn't as bad at that time. I even sold them with the plastic still on the headband...
