I find that there is a lot of sibilance when streaming some female vocals (e.g. Diana Krall on Qobuz) and Louis Armstrong. So I dial down the brilliance to 10 o’clock position or less, but Dr. West says 2-3 o’clock is the basal level for brilliance.
1. Do you have sibilance problem?
2. Do you find find that there is less sibilance with analog?February 20, 2021 at 12:05 pm #843
I get some sibilance on some female recordings(Joni). I have a fixed tweeter level of 4 ohms, equivalent to around 1:00 on the tweeter pot. I can mitigate sibilance with some slight re-toeing of my panels. Mine already have about a 20 degree toe in for a small room. In this scenario, toeing in a bit more, <1/8” actually cuts it down a notch. Depending on your toe in and room size, it may go the other way. Give it a go and report back…

DO you get sibilance with Joni on vinyl? I will try some toeing in. The ultimate sibilance test is Diana Krall on streaming, Quora or Tidal.February 20, 2021 at 4:05 pm #845kingdeezieParticipant
It’s not the speakers. Lowering the brilliance is just tone-controlling another problem.
The Soundlabs are just going to play what’s before them.
What are you using to stream, and in to what Dac?February 20, 2021 at 5:25 pm #847
I am using Lumin X1 streamer/DAC and Pass x350.5 direct.February 20, 2021 at 5:39 pm #848kingdeezieParticipant
What is your power situation? Dedicated line? Conditioner?February 24, 2021 at 3:44 pm #850
No dedicated line, but using Torus rm20 power conditioner.
Yoshi, what is the advantage of fixing the tweeter at 4 ohms rather than turning the Brilliance dial to 1 o’clock?February 24, 2021 at 4:17 pm #851
I simply measured the resistance across the pot where I normally position the tweeter pot. It has been roughly in the same position over the years. So, I bypassed the tweeter pot with a 4 ohm metal cased fixed resistor, 50 watt, non-inductive. It opened up the top end and to my ears sounds just sounds better. A very nice upgrade. Easy to remove, but why would I…!

So, you are saying that 4 ohm fixed sounds better than 1 o’clock?February 24, 2021 at 5:25 pm #853D10Participant
The best sound from my experience is to bypass brilliance control. In order to do that you must have very good upstream signal. Bad signal can bring sibilance and brightness.
I used to have control on 2 o’clock and placed resistor instead before I took brilliance control out .February 25, 2021 at 3:48 am #854
Yes, it is smoother and sounds more extended and airy. Measure your 2:00 setting impedance and select the closest resistor to that value. I found that the replacement had even more extension, so I suggest you consider perhaps a slightly higher round up value revisit or to your measured impedance.
I used 2 way tape and hot glue to set the resistor on top of the existing pot and simply resoldered the leads. Easy to change out if you change your mind.
It is worth the effort to give it a go.
