  1. Agreed David, I was thinking that the Exakt Engine chip would go in the appopriate Kartridge, and therefore the comment about not being enough room in the (main?) chassis would be irrelevant.
  2. But wouldn't the Exakt Engine be in the appropriate kartridge rather then on the main chassis?
  3. Of course, the amps have no effect whatsoever on the frequency of the room modes, but they could have an impact on how much the modes need to be tackled in terms of depth and width, but only if they do not have a linear frequency response. This is highly unlikely. Also, I'm not talking about the adjustments made to work methodically through the calculated dips and addressing their accuracy, that all makes good sense. My view is that there are SO tweaks that are being used as very narrow band tone controls and address some specific characteristics of the Chakra amps. That they work on other amps is, of course, entirely possible, but I would expect the width and depths of those tweaks that could be very different with different amps. I could be wrong. This is an observation, not a criticism
  4. I don't. helpline@linn.co.uk will give you a definitive answer
  5. David / Paul I think you're both using Linn amps. The point I was trying to get across was that the move to Katalyst meant the dips and widths of the calculated stuff are now much closer to calculated. Moving to non-Linn amps has lead to the Paul specific tweaks being no longer needed (in addition to further changes to widths and depths of calculate modes to now be very close to calculated). In other words, Paul's tweakes seem to be compensating for some characteristics of the Chakra amps, not the room. But this is a view based on a sample of one, so not that useful really
  6. There's more to music than a flat frequency response? Who knew? Must be complicated stuff that there music. Perhaps it is best to think it is very simple and continuously repeat the same old one dimensional measurement rhetoric. Means that no hard thinking has to be done before posting.
  7. Because thinking that frequency response is the only thing that matters leads to simplistic statements.
  8. I'm not sure about Exakt filter versions, and they're probably different anyway, give the change to Katalyst and that I use my own design of the filters for the PMC Twenty.26. However, the elements dropped over the changes include Paul's "first bass" dip and then 2x dips at circa 63Hz and 76Hz that tackle harshness in piano and female vocals. Of the calculated dips, they used to be around 20-30% shallower than the Linn calculations, now only 10% or so shallower, and only narrowed by the maximum that Konfig will allow (ie, not narrowed by very much).

    Unfortunately I don't remember model numbers of earlier PMCs that I've listened to, because I didn't like them very much. This was due to what I thought was a timing issue with the bass - it seemed disjointed to me. All of these were are hifi shows. Until the Twenty.26 came along which doesn't have any such issues that I can hear. I would also say that I like the Twenty.26 but none of the rest of the Twenty range. Whereas with the Twenty5 range I like the 24 and 26 but haven't heard the others. Similarly with the FACT speakers I really like the 12s but the 8s are rather too careful for my taste.
  10. On your first paragraph: http://www.sengpielaudio.com/calculator-airpressure.htm On your second paragraph, like the first paragraph, read what's been written on the subject.
  11. Paul made some good tweaks to my SO settings when I had original Akurate Exaktbox and Akurate amps. However, moving to Katalyst meant that some of them were reduced, and since moving from Akurate amps to Lejonklou amps, none of Paul's tweaks are necessary. So this stuff that Paul does seems very system dependent and not so much room dependent. I've found through these 2 major steps that each time the default SO v1 settings take a step closer to being accurate. I now have only tiny depth and width changes to the calculated dips with no additional tweaks at all. But then again, Paul might hate the way it sounds now
  12. You'd need to add a Majik 2100 power amp to go bi-active or a Majik 4100 amp to go tri-active, and the right number of active cards (2 can go in the DSi, the rest in the separate power amp). With the Majik amps, wait to have enough cash to buy the Dynamik versions, the difference in price is outweighed by the difference in performance. Mixing generations of amps is not recommended from a SQ point of view (i.e. Majik with AV5125, or AV5125 with LK era), but you could use external Akurate amps if the funds were available as they are of the same generation and sound signature as Majik. If you want an AV5125 or other Linn stuff, check out the wanted and for sale sections at www.lejonklou.com, its a Swedish site. Whilst I can't say that your buying experience is always going to be perfect there, I've bought and sold there and everyone who has been a member of the forum for a while have been excellent folks to trade with.
  13. Lovely system and room Phino. Ninkas are great speakers, I can only imagine how good they must be with that front end. You have custom granite stands on the Ninks? Did you have them made and were the holes drilled accurately enough for the cabinet bolts and the spikes?
