May or may not be relevant to your situation, but it's worth considering whether the problem is external to your system: https://www.head-fi.org/threads/persistent-background-cricket-chirp-sound-time-for-a-power-conditioner.967981/

And it's too late to lose the weight you used to need to throw around... As I trawl the murky waters of my old CD collection, next up is an album from Andy Stochansky, an artist I first heard at the Hillside Music Festival many years ago... And now back to Deezer steaming for a heavy dose...

I'm not saying it's pretty, but it would work:

Can't you do this by cascading multiple 2-into-1 USB switches? You'd need a bunch of them and the whole setup would be a bit complicated to use, but it would get the job done.

So I've had my current Head-Fi setup for 12-18 months (depending which specific piece of gear we're talking about) now, and I've listened to this album numerous times via streaming platform - both Spotify and Deezer. But ... this is the first time I'm listening to the old CD I bought sometime...

I still maintain that Seven Stones is one of the most epic prog rock songs of all time ...

If you're interested in something custom made, PM me. I could create a freestanding version of the wall-mounted rack shown here:

Cool site. Prices are a little higher than a local community center, but on the other hand we hopefully wouldn't have to deal with a huge - and really noisy - children's birthday party in the room next door.

One thing I will stand behind is my ability to hear audio artifacts being generated via Bluetooth SBC.

I don't have anything close in quality to the HEK in your signature (unless we're both willing to sprinkle a lot of magic pixie dust on my SASH Tres) but I feel like my current stable of headphones has so much diversity in sound signatures that at least one of them would have picked up an...

What constitutes "cheap" in this context?

The price swings on these things (on amazon.ca) are insane. They literally double - and then halve - in price from month to month.

I'm not 100% clear on whether you're looking for a digital signal switcher (pre-DAC), analog switcher (post-DAC) or both. Amazon sells USB-C switchers, so that may solve that problem. For analog switching, multi-pole rotary barrel switches are the way I'd personally go. A 4P4T switch for...

Finally got around to giving Alex Lifeson's solo album a spin, and it's a pretty interesting creative exploration. From absolutely savage metal tracks to funk-infused rock to an impressive 2:30 wailing guitar solo that harkens back to the great works of Joe Satriani.

Maybe it's the fact my 880's are 600ohm, or maybe it's got something to do with the way my soundholes are shaped, but I don't find them to be excessively bright or anything. Yes, they're the sharpest headphones I own, but everything in the sound signature is exactly where it should be.

I've had my MSR7b for over a year now, and I think it's time to admit the relationship probably isn't working out. They are my only closed-back, and while I think it makes sense to have at least one closed-back in the collection, I honestly hardly ever reach for these. There's just something...

Mmmmm ... spacious and sparkly.

SASH Tres 45ohm. Gotta love those creamy vocals.

I'm starting to wonder if you're an AI

First time I read this, I thought you were saying it's a good idea to remove them from your head before cleaning...

I spent a while banging my head off this and have to admit I'm stumped. Paint Protection Film something? Something to do with Picofarads?

Would love to find more artists like these guys...
