I don’t have any good explanation to this more than what I sometime detect as a very small relay clicking must be much higher in your M9, by reasons I don’t understands, and consequently make a popping sound. My Burson Soloist who has a higher level of click noise creates a bit of popping then changing volume. More so then going down than up.

 

Is the popping sound very loud and do you get it then using the remote as well?

I haven't actually tested it with the remote control, i'll do so on the weekend.

 

Regarding the level of the popping, it's dependent on the volume level, so when i'm adjusting between 0-30 it's not audible and then i start to hear it from 30+ and it gets louder and louder. as I go to 100. In all honesty it's not loud at all but I can still hear it, I guess it's because i'm not used to it.  Almost like a scratching noise.

I think I understand, sound exactly as the behavior on my Soloist. Do it happens both when you increase the volume and then you decrease the volume?

 

I’m not a technician so this is pure speculation. Can it be that your volume pot suffer from some form of static electricity? Or some dust in the pot maybe?

 

Is your setup connected to the right phase? All your electronic should be connected to the same phase. I don’t know if it can make this popping sound, but it’s very important if you want to get the best sound.

We have ever applied the steps switch volume port, these ports have quite worst consistency , only less than 25% have low click sound across the siganl while turn the volume. But still louder than the relays based volume ports.

Over 50% have the loud click noise make some people have scare .

Around 10% can't appled because the terrible click noise.

 

In some case of our test, turn the steps swich volume port slowly may have less click noise.

If the noise a bit louder than while it's band new, may have  a lot dust go into the switch , want to clean by WD-40 or other clean oil.

 

The relays volume port have not this matter, the dust can be never go into the relays because it is fully windtight .

The relays was built by the best manufacturer in China , the manufacturer also do the OEM for Omron based on the buzz of the agent workers.

It have long life than other volume ports like the potentiometer, steps switch .

I don't feel the click is that loud at all, especially if I am playing something a bit heaver sounding I can barely pick it.

It sounds like a very small click noise, no scratching or popping or anything. Just like kingwa said.

 

I Don't see the issue to be honest, and that's just my opinion.

I think it's very cool Kingwa (the designer) is explaining the volume control to us. Haha. Makes me want to get the Master 9 even more now.

People go and check out the pictures on audio gd ,s website. Itnshows some production phots. They all have heavy coats on it must be freezing there. .

Hi Kingwa - Thanks for breaking things down further. In your opinion from the relays you use in the Master-9 what % will incur the break in signal path (popping noises through headphones)? Or does every unit do it but just at different audible levels or maybe more frequently when adjusting the volume.

 

I think the clicking from the actual relay is quite cool :)

 

I'll test the remote control tonight to see if that makes any difference to what i'm currently experiencing. I just haven't had a chance to unscrew the back plate to put the batteries in.

The relays we have two steps test before install on the board, 1st is test the electric connect if well, 2nd is rock it close the ear see if have lost sound from inside.

The click in signal is very slight, most time can't hear but still depend on how many sensitivity headphones  connect .  It already is the one of lowest click sound steps volume port.

 

It is not change the volume continuely as the potentiometer volume, it is steps so change the volume can here the signal change by steps.

 

Some few steps have slight louder click sound because the resistors switch from few pcs to one pcs, not the relays matter.

My MSB dac has a stepped attenuator it clicks and it cuts the sound when moving. So I would just enjoy a really good pre / headphone amp.

If any current Master 8 owners are interesting in upgrading to the Master 9 (or are looking to sell or trade their M-8 for whatever reason), please drop me a PM. I'm looking to pick one up before the end of the month. Thanks! :)

post #851 of 876

Well, I received my funds a bit more quickly than I anticipated, so I'm ready to purchase a Master 8 or 9 as we speak! I've had one member PM me about selling his Master 8, but he seems to have fallen off the map, so I'm still interested in picking one up. Anybody have a Master 8 or Master 9 they'd be interested in selling or trading away? Please drop me a PM!

I was testing XLR vs ACSS (conecting NFB-1.32 to Master 8) , and I could hardly find a diference in quality. Maybe a little less clear, and a bit more noise.

 

But XLR has much more gain ( I have it on low gain)  vs ACSS

 

I compared volume levels and it would be something like this.

 

XLR 31  = ACSS 40

XLR 40  = ACSS 51

XLR 70  = ACSS 90
 

on high gain

 

XLR 40 = ACSS 63  

 

 

Interesting
