Hi Giorgone, With all due respect, to people that understand and hear better than me, that kind of question always make me smile.

open lids act as a resonance trap that can negatively affect sound quality.

Yes maybe, but what about the mileage of the tip? will it "never be the same again" once it has touched the record? And what about the reflecting power of any frame in the room? Not talking about the density of the concrete your house is made of… And your lacation on any tectonic plate. Doesn't even your presence in the room affect the acoustical flow of the soundwaves? Just listen to the music and let the audiophiles make their things. I, by the way, listen with the lid open, just because it's a beautifull deck that has to be seen spinning. Regards

I tend to close mine as the house is full of hairy dogs! Never noticed any difference on or off. tend to keep the lid off when using the 3000 Thorens as putting the lid back on is tricky when the record is playing!

Hey Matador, Well, that's a very beophile answer! I live in a wooden house, but indeed, each "obstacle" in the room has an effect on the sound, but these audiophiles were mainly referring to the effect on the pickup, I believe. See: https://pro-jectusa.com/2024/03/22/should-i-play-records-with-the-dust-cover-down/ B&o lids are an integral part of the design and - to my knowledge - mostly hinged and as such not meant to be removed for listening. I think, Jensen und co. did their research too... The 400x series also look nice without lid, though! Best

Have you tried with or without? What do you think? Beograms 12XX had removable lid without hinges, actually the same lid that was use on the Beocord Open Reel tape players. Those Beograms are actually and really nicer without cover than with. I really would not bother about this. But I'm curious to read other member's advice.

My personal preference is to have anechoic furniture and wear one of these when listening to music. ;-) Login to view image Seriously though, if your equipment/music elicits a physical (goosebumps) or emotional (happy or sad feelings) response, then it is doing its job. Glitch

Yes, I did, but accidentally, as the tonearm cover scrubbed slightly against the inside of the aluminum made lower section of the lid.  I felt I noticed a difference and therefore did some internet research. I was rather surprised but it looks like for the overwhelming part of  the audiophile crowd, record listening with the hood on is sacrilege. I will give it another try tomorrow, I don't follow the (acoustic-) science anyway, but my ears. A nice hinged lid is a cost factor so that's probably also an understandable reason for omitting it.

I get your point, have two dogs too but the odds are low to get their hair on a spinning record :-) Clothes are normally the biggest hair-traps. Dust is worse for the vinyl and more widespread, I think.
