There are pics on here somwhere.
A lot of work went into it.
Before the DBLs he fixed the top box of his SBLs to the wall.
There are pics of this also on here somwhere.
It would be nice to see them again.

I remember this.
Have you tried to email again?

That's Ulrich Hohn (from South West Germany actually)!

I hope he does not mind me posting this!

George thinks his are close together.
But at least his face you
Did you find his SBL pics?

Who's George? You mean Fredrick!

Dear Julian,

Golly! Even I doubt I could find that picture now! And I took it!! Thanks for saving it and bringing it out again!

The issue of shifting the microphonic components in the cross-over by removing them from a vibration engine realy raised passive driving on the SBL to a level somewhere well towards active, though slightly less revealing. It got a very clean and listenable sound, which was actually more accute but less aggressive.

Please, Julian, send me an email, and I will replay. Address in Profile.

Thanks for the memories re-awakened by that photo taken in my flat in Henwick Road in Worcester in about 2006. Frank F heard them in exactly this configuration, with the special Sonority Design isolation platforms that are underneath them. I am not at liberty to discuss these as I was associated with their developement. Forum rules is Forum rulz!

ATB from George

Love it.

A cakepan in suspension!

Well,I know when my system sucks. I don't need for someone else to tell me that.Go to gene rubins site and look at my system. Gene wrote the captions.
Pick up your phone. You no how to use one don't you?

I am still using the 552 preamp. When I had the 6x135s/DBL setup I had a 52, and borrowed a 552 for a single evening- and was sufficently beguiled by it to eventually get my own. Details to be found at http://forums.naim-audio.com/eve/forums/a/tpc/f/4801938...681969795#7681969795

By the time I did get the 552, I had already gone to 1x300/4x135s. So my exposure to the 552/6x135 was limited to only a few hours.

Yes Fredrik,

They were superb and had some really magical properties. The stands in particular isolated the speakers at about 5 hz and, combined with the isolated crossovers, made a really excellent sound with clear deep bass and the usual excellent SBL mid range and not a bag of sand in sight!!

Ron: totally agree with your comment on the other thread: "Never upgrade until you have maxed out the capabilities of what you already have."

Just done a little more digging and found this interesting thread which also has a bearing on my choice (555 or another 500 for the active DBLs).
555 v CDS3

Currently I have the CDS3/555PS/HiLine and so I would be exchanging the CDS3 for the 555. Reading the thread above, it would seem that a lot of the benefit has already been gained with the 555PS and much of the rest could be about presentation and personal taste. Changing the active setup from 500/300/250 to 500/500/300 may be the safer bet?

I would very much like to hear from Geoff P or others who have had direct experience switching between the CDS3 and 555 (especially if they have been running active). Btw I am now running with the 552.

Hi Gavin,

I have attached links to a number of posts I have made covering my experiences with active DBLs and mixing amps. I would endorse the better amp on higher frequency approach. In addition I made the transition from a CDS3/555PS to a full 555 and found the change to give me distinct performance benefits.

In terms of your system, I would suggest that you try reconfiguring to 500/300/250-2 and living with that for a while before considering any change. I would also strongly recommend that you link up with Peter Swain and look to giving your overall system setup the once over as there are substantial gains to be made from attention to detail in that arena. Peter and I have been on quite a journey with my system over the last few years and you might find our experiences relevant to your situation. I will observe that on that journey I did have the opportunity to listen to a number of 552/500 systems into a range of speakers but none of those arrangements stirred my cocoa as much as my active system at home.

BTW, don't overlook the gains to be achieved by putting your system onto Fraim. I made that transition some time ago and putting aside the performance gains to be had in terms of musical reproduction, I found that the hum from power boxes was reduced - which is no bad thing when you have more of them around in an active system.

I have put an email address in my profile should you wish to talk off line.

Gavin.... you want to hear from me but all I may promise you is added confusion.

I am slightly guilty of intransigence regarding the CD555. I am now back with a CDS3/555PS in my 552/500 setup for the reasons given in this Re-assessment about halfway down the page.

It is perhaps a cautionary tale though since others also can be seen to comment similarly. It is also most applicable to those that are 'Vinyl' nuts and should be viewed in that light particularly if you are hard over in CD land.

I run passive with a pair of ceramic cone Kharma speakers which are a class act IMO and pretty fast as a result of the diaphraghm material. I had the pleasure of hearing Frank F's active SBL's on 2 X 300's recently and reckon my passive 500 setup has very similar properties in terms of clarity, speed and dynamics. This is a factor because I find the CDS3/555PS combo really reaches it's best with such systems which punch out the rhythum and dynamics more than more sedate systems.

So...I would do what you can to assess the relative merits of the active configurations discussed here AND see if you can get a loan of a the PAXO's to run passive with 1 x 500 in comparison. An expert dealer with long Naim experience such as Mr 'Cymbiosis' could swing that demo fro you I am sure.

I would treat the CD555 as the next demo AFTER settling the final strategy for driving the DBL's and getting that up and running. Then you will have the right comparison against your CDS3.

regards
Geoff

I was looking for the thread I started for the 555 but it looks like I didn't start one. Thats not like me, I wonder what happened?


Gavin, I suggest you get hold of a 555 head unit and have a listen at home before you do anything else.


Regards

PB
