Burmester 911 mk3

Get the 100 phono.

(...) I was under the impression that the 948 works parallel to the mains so it surprises me that it would be restrictive of current which I think would be the culprit of any dynamics issues?

Are you sure the 948 works in parallel? I have never seen how it really works and could not find the patent they have on it - most probably it should be explained there!

Garry, Rocco and Joe, thank you.

It's right. The 948's is alike a power amplifier that works in parallel mode with the AC power supply and, as an active system, compensates any DC offset in the AC mains from the wall socket. The 948 therefore influences the power supply from the outside, without constraining or reducing it.

Thf99, one more thing to check - behind your 32A switch - where it is wired to the mainboard of the house, is it an ELCB? If it is, consider changing it out to an RCBO. (This is only applicable to 230V-land). You might find quite a large improvement in micro dynamics.

Yes, it's an ELCB. OK, I'll do that. Thanks for the advice.

 

[Thf99]

Well, I am now running my 911 straight from the wall outlet next to where the 948 is plugged in, no hum in the 911 which I otherwise would have with my poor mains so the DC correction is still working. It is sounding absolutely magnificent but then it also was before, it's impossible with any degree of certainty to tell if it's an improvement.

For your system to work best and if you are using the 948, you've got to use two 948s (one for the amp and one for the rest of your equipment) and three if you go mono. This will put to rest any issues with dynamics.

You're welcome. Back in Singapore, when I changed out the ELCB for the magnetothermic model RCBO from ABB, there was quite a substantial improvement. That wasn't with Burmester electronics though, it was with FM Acoustics. In either case, it will cost you less than an inch of expensive power cable!!

When you use more than one 948's within the same electric line, seen that It works works in parallel mode with the AC power supply, each 948's could disturb the right operation of the other one.

If you like to use additional 948's you shall have the direct and dedicated voltage lines from the electricity meter. However the 948's was designed to be used alone for all the system. I say again that the loss of dynamic (micro & macro), even 911's monos or 909's monos, was never an issue. At least in the systems listened it was never restricted.

Yes Rocco. Each 948 should have its own dedicated power line.

Rocco,
Are you saying that the 948 acts as a variable load, using the intrinsic (internal) resistance of the AC mains wiring as the serial element to compensate DC? Very interesting.

Basically, the 948's is a power amplifier that works in parallel mode with the AC power supply and, as an active system, compensates any DC offset in the AC mains from the wall socket. The 948's is a regulated power conditioner which actively suppresses distorting DC components in the power lines.

I have had stunning success with Sound Application Reference Line Stage power conditioner. Sorry if I don't buy into the all Burmester camp. Sound Application's new one is $12K, so I will stay with my 3 year old one. . I do love the Burmester audio racks. Simple yet very elegant.

 

[Steve williams]

I also use Jim Weil's Sound Application Reference Line Stage and like you am sticking with my several year older version which was a mere $6K

 

[MarinJim]

I wonder, when Burmester comes out with the 911 MK4, what do you think they will improve and/or change?

 

[docvale]

It's gonna be a MkV...

 

[joeinid]

It's gonna be a MkV...

I think the number 4 is unlucky in some countries.

 

[MarinJim]

Well, whatever the number will be, I wonder what the target improvements will be.

 

[MarinJim]

I think the number 4 is unlucky in some countries.

So is 69..............not.

 

[hiroshige]

I think the number 4 is unlucky in some countries.

Very true. In Japan, the number four also means death so you'll see some buildings omit the fourth floor and go from third to fifth.

 

[MarinJim]

So, no 911 MK13?
