Modded headphones with qudelix at the core
When I received the Qudelix 5K, I had already modified a pair of Superlux HD-681 headphones. I previously soldered my own balanced connections to the drivers, providing multiple ways to connect and...

I am in the midst of a 300 hour burn-in but, I will say I am enjoying how this set sounds so far. Before I received these which was btw late by a few weeks, I purchased a Sony/Kimber Kable MMCX...

Should I exchange the PC38X for better headphones?
I bought the PC38X headphones FOR GAMING and they are great, but I have NO use for a Microphone since I don't do competitive gaming and I was wondering if there were better headphone options at a similar price without a headphone, where (presumably) more of the cost was put into making it sound better. I also find that my PC38X don't get quite as loud as I would like and I was wondering if a cheap amp like the iFi Go link would draw a little more volume out of my phones. https://www.amazon.com/dp/B0BN6MM822?psc=1&ref=ppx_yo2ov_dt_b_product_details I went with the PC38X since it was considered the best bang for buck headphones. I care most about using spatial apps like DOlby Atmos and DTS Headphone:X. Suggestions are welcome.

Looking for a gaming/content audio setup
Hello! I'm looking for recommendations on audio setups. I'd be planning on using it mostly for gaming. Preferably I'd like a pair of large closed back headphones since I have a big head and jaw. I'd also like to hear myself through my mic with mic monitoring. As far as budget goes, I don't really have one. But under 600$ would be nice. I can go higher if needed. The audio setup would be connected to a high performance PC. Thank you in advance for any recommendations!

$10 Drop Coupon Email not sent?
Trying to buy some gear off Drop for the first time. I was told I would receive an email with a welcome to drop $10 off promo. I never received that email. Drop was able to send me emails for my login token and email for Password update. But for some reason the $10 off coupon was never sent to me.

New here
Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.

- make sure you don't have a ground loop caused by plugging the DAC and amp or PC on different power sources. You shouldn't have it, since the D30 doesn't have ground connection, but checking this is pretty easy so I'll explain how: turn on the DAC, then the amp, and when you can hear this buzz, unplug the RCA inputs from the amp. If the buzz goes away when you unplug the RCA and comes back when you plug them, you have a ground loop. To prevent the loop, try plugging your DAC, amp and PC on the same plug splitter, as close as possible. If it does not work, well, you always can supress one of the grounds and pray for the best (risky) or make some further research. I did first when using my PC as source before getting the D30, don't blame me, I swear I tried to fix it by any means.
- use another source to test if the problem is on your DAC or amp, for example connect your phone to the DAC using a 3.5mm to RCA cable. If it sounds fine, you know the problem is on your DAC or PC, or the connection between them.
- since you said the buzz is more audible when you're playing games, I bet there might be some electric noise on the USB port that connects the DAC to the PC. Try using other USB port, both front & rear, maybe you find a less noisy one.
- if nothing works, try with other tubes and/or opamps. Check the internal components, soldering, caps, volume pot... If everything looks fine, contact support.
Some other free tips: - when turning on, first turn on the DAC and a few seconds after the amp; when turning off, do the opposite (first amp, then DAC). - before tube rolling (changing tubes), turn off and let the amp cool down and discharge for a few minutes. Unplug it from everything, and remove the tubes before moving jumpers. Same when changing gain switches, and always move both. - double-check your jumpers when switching between different tube families. If you misplace jumpers, you could damage tubes or even blow the amp, so make sure everything's ok before turning on the amp. - always use "matched pairs" of tubes, and if you suspect one of your tubes sounds different (louder, noisy, or whatever) swap the tubes and test if it goes to the other channel. If it does, you know there might be a problem with one of your tubes, or a mismatch. - set the gain switches according to your headphones. If you don't use any high impedance or low sensitivity cans, you can leave it at the "low" gain. Mine is "high", you can see it in the picture. - this kind of amps usually suffer some channel imbalance when the volume knob is very low (let's say under 15%), so try keeping the volume knob above that level to prevent it. You can always play with the software volume, so not a big deal. But also keep in mind running the amp at max volume all the time it's not good, so find a "sweet spot" for the volume knob where you can have the software volume at a reasonable 60-80% at your desired volume, so you don't have to constantly play around with the knob. - don't let the amp running for more than 8 hours or so before cooling down for a while, this thing gets pretty hot and it might damage the internal circuits or even cause a fire if something goes really really bad (not common). But don't turn it on and off too often, it also shortens the life of the tubes. As a rule of thumb, if you're considering turning off the amp for a while, if you'll turn it on again in under 15 minutes, keep it on (unless it has been on for too long, in that case turn it off and let it cool down for at least 10-15 minutes). - try to avoid plugging-unplugging headphones while the amp is on, it's not a big deal but it causes small shorts that might damage the amp in the long term. If you want to make a quick A-B test it's ok, but don't abuse it if you want your amp to last for years.
