noise

Hi, I have an unorthodox setup. I have my computer connected over HDMI ARC to the NAD T748 receiver. Using the receivers RCA pre-outs I connect it with 3m 2xRCA to 3.5mm jack cables to two pairs of KEF LSX speakers for 4.1 surround (Awaiting one LS50 anniversary for center channel). I have...

PCM to DSD = better sound quality?

Hi I just got a Marantz Cinema 50, feels like a nice unit. I’m a bit concerned though, I’m hearing noise from -7db (75 on scale mode). It doesn’t feel right to start hearing noise at this level from a « premium » product. Totaly audible at max level. I thought such a unit would be dead silent...

Folks, I need some help treating my house. My spouse and I both work at home, and I can hear him from the 1st floor when he's in his office on the 3rd. Any suggestion on how I can treat the walls by the stairwell?

Dear all, I have a Cyrus 7 with this problem: when I turn it to standby mode there is a ‘pop’ noise on speakers at quite high volume. When I switch between channels there is also similar noise but at much lower volume. And when the source is off (in my case TV) there is some time similar noise...

Brief overview: Klein + Hummel O110, around 15 years old, making noises as seen in the video below. Quite temperamental tweeter electricity noise, started around 3 months ago, 60% of the time it works perfectly fine, it is unusable when this happens. The noise still happens when XLR cable is...

Hello, I recently bought a new DAC (Topping D90SE) but I'm having a hard time making it work properly at 24 or 32 bit via the Windows Sounds settings, it sounds super noisy at any kHz (from 44.1kHz to 384kHz) and also buying a Ground Loop Isolator (Topping HS01) didn't resolve the problem...

It took a long time to shift from linear power supply to SMPS in high end audio producs. Nowadays, SMPS seem to have completely replace linear ones except in some niche areas. I've often heard the advice to beginners to not touch SMPS and stick to linear supply for DIY projects, because...

I have an AV setup with a Denon X3700H AVR connected to a TV and an Nvidia Shield which works without issues. The moment I connect my desktop PC to the AVR through HDMI, a crackling sound starts coming through my speakers. This sound comes out regardless of the selected input or volume level on...

Hello guys, so today my cayin iha6 started to output static noise on the left channel of the 4pin balanced output. There is 0 audible noise on the unbalanced output. I am 99% sure the issue comes from the amp. I have tested on another power outlet without anything but the headphone connected...

Hello everyone, this is my first post here. :) I am having an rining/humming/noise issue with my Edifier s730 subwoofer. I have attached an audio file with the noise I hear (recorded it with a cheap shotgun mic and newbie cleaned it up in audacity to hear it better) and some pictures of the...

Hello All, When playing DSD files on the D90SE, when a song finishes and another starts, a relatively low-level but still audible static/noise sound starts playing constantly, whether music is playing or not, whether PCM or DSD files. This static continues until I turn the D90SE off and on...

https://www.aboutamazon.com/news/transportation/amazon-prime-air-prepares-for-drone-deliveries What could go wrong????? I wonder if it helps to put a net up in the yard to snag the package or would it snag the drone instead? Will these fly under my porch so the package is not left out in the...

I am seeing and hearing a fair bit of unintended noises coming from the USB-powered Audient ID4 mk. II Silence, normalised to 0dB: Zoom-in Observations so far: The noise can be heard when PC is idle. It gets worse when GPU is busy It gets better when CPU is stressed. Even then, there are...

Archimago tested various RCA cables for their noise performance, and came to the conclusion that it doesn't matter: https://archimago.blogspot.com/2013/05/measurements-analogue-rca-interconnects.html I somewhat had a hard time finding information via the search function here if shielded cables...

Hello hello! I was at the Montreal Audiofest this weekend and we came across a room where they were showing a ''power management system'' https://dracoustics.com/en/produit/antigone-power-management-system/ basically, this thing is all about reducing noise on the power in of the amplifier (as...

Hello, I have Darkvoice 336 SE tube amp connected to DT 1990 PRO and that I use all the time and I wanted to try some different tubes than my old trusty Sylvania 6SN7 GTB E6B ones so I bought one KenRad 6SN7GT (pricey little thing) and two PSVANE UK-6SN7 (ordered one but arrived as pair) KenRad...

I always wondered does ethernet cables cause ground loops? I was told all my life for the most part that ethernet cables can carry surges and ground loops but I never really encountered this. Our internet for the most part is stringed across various network switches and routers via different...
