    Long shot - does anyone know if there's a readily available replacement for the Sabaj D5 display?

    Sabaj support is non-existent (I had an issue with a different Sabaj product; contacted support and 8 months later am still waiting for a response) so I will have to fix this myself, if possible. Is the LCD used a common OTS component and, if so, does anyone know the model number or how to...

    MDR-z7 and Sabaj D5 - no sound from XLR output. Is this cable wired correctly?

    Output is correctly set in the D5. Any help is appreciated.

    Are XMOS drivers needed for a DAC used only for gaming and streaming content?

    DAC: Sabaj D5 One of the differences I see with the XMOS drivers installed is I can select 16 and 24-bit depths as opposed to only 32-bit with the default Windows USB driver. Are XMOS drivers only for those using an audio interface and/or playing back lossless?

    How different is the HD600's sound signature from Beyer/Drop DT177x?

    I dislike everything about my DT177x so I'm looking for something that sounds different, if not better. Would the HD600 fit that role?

    What's the deal with the Bellari HA543 amp?

    I'm unable to find a single genuine review from an audio or headphone site for this amp that's been available for 5 years. For the price - they can be had for as little as $79 - I have trouble believing the specs and features listed on the official site. It obviously doesn't have real balanced...

    Sony MDR-Z7M2 vs. Beyer DT 177x GO

    Curious if anyone has experience with both or know of any comparisons. For desktop use with DAC and amp.

    Fostex T-X0: How can I fix a solder joint on the polyimide film?

    I have in the past been pretty careless with the soldering iron when working on these. Now, however, due to unfortunate events the Fostex are my only headphones. Anyway, because of all the tinkering I've done, the positive contact of one of the drivers has slipped off the film and I'm unable to...

    Mods to improve Amiron Home's mid and low-end response?

    Are there any physical mods I can perform to make these a little livelier? I'm not after accuracy, just a more dynamic and impactful sound for games and movies. The only thing I've done so far is swap out the rather flat and uncomfortable stock pads for the ones from a pair of Fostex T-X0 (I...

    Fixing headphones, quick question about pos and neg wires.

    The left 3.5mm jack of my Beyer Amirons separated from the two wires with no indication of which went where. Would both 3.5mm inputs be wired the same -- black to +, white to - as the right one is, or should one be wired differently? Would like to be certain before soldering. edit: remembered I...

    Reasonably priced cable with good build quality for Amiron Home?

    I received a pair of Beyerdynamic Amiron Homes in a trade but with one of those horrible "Fantasia" replacement cables all over Amazon. Unspurprisingly, now after very little use, the left channel is cutting out. Wiggling the end plugged into the amp brings it back temporarily (tried inputs on...

    Reasons why DAC's integrated amp sounds better than Magni 2U?

    Beyer Amiron Home PC USB to Sabaj D4 Schiit Magni 2 Uber When using the Sabaj as just a DAC and the Magni as amp, the volume (gain/level?) knob stops making any noticeable difference at anything over ~10 o' clock. Switching between low and high gain on the amp makes no difference. Other than...

    Is there a secret to taking good pictures with an iPad Pro?

    2020 12.9" iPad Pro. I don't know if I'm overlooking some settings or if the camera is defective, but I have yet to take a picture that could even be described as adequate*. Despite clean lenses, proper lighting, and steady hands, pictures are out of focus and seem to have some sort of...

    Powered monitors noise and DIY magnetic shielding question

    I know this isn't strictly headphone related, but I am using a headphone amp as a pre-amp, so there's that. I've had a pair of the Monoprice 8" powered monitors for quite some time but due to their unbearable hiss/static they've spent most of their life in storage. I decided to try tracking...

    PC USB -> DAC -> Amp volume/level question

    USB -> Sabaj D4 -> Magni 2U -> Sony MDR-z7 All three have volume control. What's the best way to set up volume/level in this chain? Obviously the Magni would be used as the master control, but should the DAC and PC before it both be at 100% or something else?

    Is there a guide or mod for using different earpads on Sony MDR-z7?

    My biggest problem with the z7 is the pads are thin enough that my ear touches the driver (there's very little in the way of a grill.) I've experimented with placing different materials under the rim of the earpads but results weren't great and I'd rather just get a new set of pads, maybe velour...

    What's the trick in disassembling the Sabaj D4?

    I know it's not a popular or well-known DAC so I'm not hopeful of finding an answer. An hour of searching led nowhere so this is my only other option. I'd like to replace the 3.5mm input with a 6.35mm jack so I no longer need the huge bulky adapter. Basically, with the rear panel off, the PCB...

    Two-part question regarding Sabaj D4 and level matching.

    I recently bought a Sabaj D4 and am really enjoying it. The improvement in quality over both onboard and a JDS Labs OLDAC continues to surprise me. It's not a high-end DAC, but for me it's all I'll probably ever need. Anyway, I've been using the D4's integrated amp but I'd like to add in my old...

    PC > preamp > powered monitors gain staging question.

    I assume it's 100% PC and speaker amps and use the preamp for adjusting level, but I'm asking because there is quite a bit of audible noise from the speakers when their gains are set to maximum that isn't there at lower settings. Is this a separate issue or is there a different way to set the gains?

    For powered monitors would a discrete pre-amp be better than the Magni 2U's?

    I have a pair of Monoprice 8-inch powered monitors on the way and am looking for the optimal signal chain from my PC. I'm currently using my motherboard's integrated audio while I shop for a DAC. I'm wondering if the Magni's pre-amp is sufficient or if discrete would be noticeably better...

    Can you recommend a quality DAC diy kit?

    I prefer a DIY kit so I have the option of modding or subbing components. I've spent a lot of time browsing kits on AE and am left with mostly confusion. It seems some don't include the needed USB daughter board or actual decoder chip which, combined with the terrible descriptions, makes any...

    How much difference does an amp's transformer make really?

    I'm trying to decide between a few DIY amp kits - one uses a sealed toroidal transformer, the other a wound circular type (the technical name of which I don't know.) What practical differences would the more expensive sealed type have over the other if any? Edit: visual aides:

    Safe ways to fix dents in drivers?

    I just noticed the right driver of my Sony MDR- z7 has a ding in it, no doubt from my fumbling with them. I tried to push it out from the back with a Q-tip and very light pressure, but I had no idea just how thin and fragile these diaphragms are. I stopped from fear of making it worse. Does...

    Distortion - or what I perceive to be - on some louder lower frequencies.

    I don't think it's an intended effect as I've heard it across multiple mediums of all qualities. It seems to only affect lower mid-range frequencies, most noticeable on loud passages like explosions, some drum beats, etc. It sounds to my untrained ear like the amp doesn't have enough headroom...

    Good Chinese knock-off DIY amp kit?

    From what I've read there are some nice headphone amp kits available - aliexpress seems the most oft mentioned site - based on proven designs. The only issue is I can't find any of these, mainly because I use a mobile device most of the time and that site is a mess in mobile browsers (no doubt...

    Simple mod(s) to improve or change the Sony MDR-z7's sound?

    I can't explain what exactly it is that makes it difficult to listen to the MDR-z7 for long, other than a tonality that disagrees with me and quickly results in fatigue. However, they are incredibly comfortable and easy to drive, so I am asking if there are any simple mods that will affect the...
