250 vs 300

From an acoustic point of view “big windows” are no different from drywalls.

This means that windows generate the same acoustic problems as drywalls.

I’m sorry but as long as you didn’t measure your room, you can’t state it has no problems.

Considering the shape of your room, there is no doubt there are some obvious acoustic issues.

All rooms have acoustic problems. Even those perfectly shaped!

You can’t avoid room reflections, and therefore comb filtering, especially in smaller rooms. And you can’t avoid room modes… in a room :wink:

I’m agree, hifi is hobby and all hobby have intricate parts that are pleasurable. I hear difference when I bought extra shelf to raise burndy from floor. Not imagination but a real difference in clear music. I don’t understanding why some people get upset about what other people doing! but this is life maybe. best. Jamu

I think like most tweaks, its room and system dependent. If your floor is acoustically dead and your speakers roll off at 45Hz, you may not notice much difference getting cables off the floor. If your floor buzzes along with the music and your speakers are putting out 20Hz, there is likely to be more benefit.

I find cable dressing one of those things you notice over time because something doesn’t sound quite right, rather than noticing an obvious problem the moment a cable touches the floor/wall.

All Naim cable upgrades (PL, HL & SL) are mechanically decoupled to prevent vibration reaching equipment via the cables. Standard cables don’t have any decoupling which would seem to say Naim are happy that things will work fine with a little vibration but will be better if you can avoid it.

I wonder if there are technical reasons there isn’t a decoupled Burndy upgrade available, since this seems to be the cable many people find particularly sensitive.

Pedantic, moi?

All the acoustic treatments I tried, 3 different models , monster bass traps, corner bass traps and another model I don’t remember, had NO POSITIVE effect for my tastes.
I spend a lot of time, tried all the places possible in my room.
If on some aspects the sound improved on Hifi criterias, globally I didn’t liked the effect. It sucked some life and airiness from the system.
I am not the only one to think that, but unfortunately you state that indefinitely as an universal solution for all .

It works for you, not for me. And please, don’t respond me that I like room reflexions. I have finite elemente cerabases under speakers which were the most effective in my room. As the choice of speakers which work well in my room.
Only one panel in a corner is left, because it has a positive effect.

So you agree or don’t with me, Nigel?

I do agree that cable dressing, particularly with Burndies, can produce a worthwhile (noticeable) improvement.

My comment was a tongue-in-cheek quote from a character in a popular TV puppet show.

I couldn’t guess what it was quoted from 🥸

I’m not questioning how your room sounds, obviously. It’s your room.
I’m not questioning your taste, whatsoever.
And I’m not saying you should use acoustic treatment.

Relax FR…

I simply stated two corrections :

  • windows aren’t more “problematic” then common walls.

  • your room, like any other room, has acoustic issues (and that’s pretty normal).

Denis Foyley, Acoustic fields.


You can be in a room that has a lot of wood, you could be in a room that has a lot of carpeting, you could be in a room that has a lot of windows. Each has its own distinct sound, even though they’re the same size room and the sound sources are the same in each room, they will all three sound differently. What is the difference between the three rooms? Materials. Materials that the room is made out of. So, that said, windows and glass are the worst sound you could ever imagine to bounce any sound energy of (them). So reflections from window surfaces have to be treated.”

It absolutely doesn’t contradict the fact that glass and drywall have roughly the same acoustic properties :laughing:

In fact, huge glass surfaces tend to absorb low frequencies a tad better than drywalls.

That’s why, when a choice has to be made, placing speakers against windows is a better choice than shooting at the windows.

So better have concrete walls vs big windows, not?
I have only concrete walls. Little windows.

Are you living in a refurbed Normandy WW2 beach bunker per chance FR? :rofl:

There’s always the possibility that it hasn’t been refurbed

Yeah maybe not the greatest for this time of year :sneezing_face: ATB Peter

My living room has 3 concrete walls and one, short dry wall.
It’s a very old building.

Interesting those bunkers, even from an architectural point of view. Quite similar to some Brutalisme inspired buildings.

WW2 and the fifties are very interestings periods.
