My understanding, based on the presentation by Linn's Technical Director at their 40th Aniiversary Celebrations, is that the differences between the AVI ADM 9's and 40's and the Linn Exakt system are that:

 

any analogue signals - eg from an Urika equipped LP12 - are converted to digital.

 

The active crossovers are digital

 

Digital equalisation is applied to the signal to counter room effects and speaker driver and port manufacturing tolerance effects

 

Digital phase correction is applied to the signal to take into account phase differences from the position of the various drivers relative to a given listening position

 

There are multiple DACs for each speaker. One for each driver. The DACs are placed after the active crossover and signal processing and just before the power amps.

 

The Linn Exakt system is software upgradeable. Also if the user changed his room or speakers or a speaker driver the system to could be reconfigured accordingly

 

 

In summary the Exakt system offers digital signal processing combined with digital active crossovers.

Looks very similar to the soon-to-come Avantgarde Zero 1.

At the moment it is a digital transport/source switch called the Exakt DSM which then feeds a digital signal to the speaker which has built into it a digital receiver that digitally splits the signal for each speaker drive unit. Each of these signals is then converted by a separate DAC into an analogue signal that feeds a separate power amplifier which then drives each drive unit of the speaker. Perhaps easiest to think of it as a current Linn DS/DSM with the DAC removed and placed in a truly active speaker with a digital crossover.

??? Yup!

still, it's good to see active digital systems (where the signal is kept in digital domain as long as possible) to gain interest in hi-fi because IMO it's the way forward. DSP is really a formidable tool to counteract speaker design flaws.

It's only overpriced if it isn't any good...

I doubt the Xeo has a digital crossover, and is also limited to 24/44khz audio.

For the sort of money the Linn system costs I think I would rather own this active DSP speaker system excellent!

Ladies and gentlemen, I give you the Squeezebox Boom.  All of the above, plus a streamer for less than £300.

http://wiki.slimdevices.com/uploads/a/ad/Logitech_Squeezebox_Boom_Audio_Design.pdf

To be fair, Sonos go down the same route with the Play3 and Play5, and this is the cornerstone of Meridian's range. 

I have been banging on about DSP speaker / room correction, multi DAC, amp per driver for ever.  My son's DT project was a DSP multi DAC / multi amp  / multi driver 2.1 speaker setup.  Based on:

http://www.minidsp.com/products/minidspkits/2-x-in-4-x-out 

The challenge for the likes of LInn is that the hardware is dirt cheap (the active crossover / DAC linked to above is $80), but the development costs are a fortune. This benefits the volume producers, and makes the likes of the Boom extremely good value, or the Linn products extremely expensive, depending on how you look at it.

Anyway, I am glad that Linn are going down this route - it makes good engineering sense. Just lets not pretend that they are first at it (Manic - I mean you...).

No ! - you should know this one. It's only overpriced if it doesn't sell.  ohhh sure

Last time I heard  a memorable Linn demo at a show it was the .... LP12/ Ekos SE setup.

Anyway John, can you sort out my Cambridge Streammagic 6 internet radio connection before I send it back to Richer?  pray

Actually, I was wrong anyway - it's only overpriced if it's not made by one particular manufacturer.

Is there a thread somewhere?

So?

Sorry for the curtness, but unless they are going to sue Linn for patent theft (or whatever their complaint is) then it's just a couple of blokes muttering into their beer.

What is their complaint, assuming you're correct in saying they have expressed one?

So, where is the source?  Will these speakers store their own music files or stream direct over wi-fi?

Is the method of using direct digital similar to these:

?

I know they're a different offering, being powered and not active.

John - under network players. I also wrote a semi-complimentary review in your review section!

Not as far as I've seen.

You are absolutely right Alec.  No complaints from AVI other than the imaginary ones, I was surprised it took so long to bring AVI into it.

Perhaps a realisation that AVI and others saw the way the market was going long before others in the hifi business did. [Mags included of course]
