IIRC, the damping pieces were only for the bigger extruded sleeve kit. However, most found they sounded better without damping.
They don’t run hot because there is nothing on top… I’d try the paper. It would look a lot better too. Some people use ice hockey pucks for this issue, though whether they are readily available in Brighton…
Not a Naim amp, the top plate was held in place by bolts on three sides, the holes were Blind so the bolts didn’t fully tighten the plate. The the front of the panel slipped into a slot in the fascia. I cannot remember whether it was Rotel or Marantz, it went some time ago. In Dad’s useful box was some bookbinders cork sheet, very fine grain and about 1mm thick. I used clear Bostick to glue strips about 1cm wide around the edges.
So the ringing is louder than the music? …and it’s not feeding back through the system? I find this most odd, i have to say. I hope you find a solution.
Note: the ‘ring’ from Fraim glass is preferred to face upwards in where it mates with the kit.
Point taken, I could try something and keep an eye on temp and remove if it starts getting hot, they usually are luke warm at most where the transformer is. Perhaps something that doesnt totally cover the top plate, something like your puck idea sounds good.
Being Brighton maybe a half full can of lager and a beer mat might work…come to think of it…
Do you have a tt record Puck or Weight try that
Is it possible your wiring housekeeping disrupted the order you had previously?
No
It’s not going off like Big Ben, but yes definitely audible.
For some time I thought I was hearing a nasty room reflection colouring the sound particularly at higher volumes. I messed around with the room furnishings, speaker positioning etc on and off for years. It’s a 200 year old quirky cottage and for a while I have thought there was a pipe under the floor ringing when playing loud. Lifes too short and with only 24hrs in a day I’ve, until this discovery, been pragmatic and lived with it.
As I said at the OP, I cant believe I’ve not noticed the ringing casework before, yes I’ve been aware of ringing of the casework if physically tapped but not ringing in sympathy with the music generated energy in the room.
BUT. I say, not noticed before, but been thinking and I recall a similar situation at my old home. As I started to upgrade my old system into a Naim based one I began to notice a sort of edginess/colouration on some transients like heavily struck piano chords. Again I thought all kinds of things were causing it and chased myself around in circles, eventually I thought it was the casing of the TV resonating and tried damping it and sealing the joint around the casing with silicone sealant.
Then I got a Quadraspire Reference rack to replace my steel Sound Organisation rack which I convinced myself was ringing. The Quad sounded amazing in comparison and I stopped noticing the colouration.
Now 12 years ago I moved to my current quirky Cottage, much better acoustics, more open detailed and transparent sound, but I’ve increasingly become aware again of that ringing colouration which has slightly niggled.
So after all these years, I’ve finally found the culprit, ringing casework! and as I have 9 Naim boxes in my system that’s a fair bit of unwanted added noise into the listening environment.
Would you Adam n Eve it!
How about a couple of sandbags?
Not the ones you use for flood defences - try a couple of freezer bags with sand or maybe caster sugar… if it works, find something that looks better!
Works for my speaker stands. Never bothered for the SO table though!
How close are you sitting to the rack? Is it possible to move the rack further away from your listening position? I think the ringing is there for all of us, but could it be that your proximity is the issue?
As I said moving the system not an option.
Cheers
If so, I find it quite ridiculous, audio equipment designed to give the best possible musical performance that audibly rings when listening to music.
Not really, it’s not as though I’ve got my ears resting on the casework.
The caster sugar would certainly sweeten the sound
I don’t recall any of my olive kit “ringing”. Is it the 90 that’s doing this?
Yes, mostly the Ixo, 2 Nap 90’s, flatcap & CD3.5 the old slimline components.
I dont hear it so much from the newer 202/HCDR and Olive HC that are other Naim components in my system.
If I clap my hands the ring and the decay can last a couple of seconds, or even just raising my voice can make them ring. It’s as loud as if I tapped the casework, now multiply that by the 5 slimline components and you can imagine how significant the noise is
Custom design make a constrained layer damping steel or aluminium single top plate which has been specifically designed to be seated on cd players and amps to combat resonance and ringing of top casework. I have their speaker stands with their acoustic steel top plate and can tell you they have worked wonders for improvenents in SQ. They are not cheap and can be bought in certain sizes but they work beautifully. I’m suprised more people haven’t discovered this anti-vibration solution.
Thanks Henryski, will see if I can do a search, if very expensive though may outweigh the value of these little amps. Although their musical value to me is far greater than the sum of their parts
Cheers
My first system was CD3.5/FC/Nait 3 and I don’t recall it ringing. Weird.
