  1. Hmm. I suppose then that it depends what you want to get out of the project. If the object is (and I mean no disrespect) to do something crazy just for the sake of doing it, well and good. If the object is to end up with an LP12 that someone can sensibly use, the fact is that the bearing is arguably its key component, and at the moment there will be dealers who have more Cirkus bearings than they know what to do with. Making friends with a dealer who can sell you used parts at reasonable prices and (I didn't say this) can quietly let you have copies of useful Linn instruction sheets could help your project along more than somewhat. David
  2. Excellent report; thanks for sharing so informatively. When I had the Krystal/Urika II combination, my dealer tried a couple of resistance settings, but I settled for the default. Now I have the Kandid, I have been happy to stick with the defaults. I'm not going to say how much of an improvement the Kandid has been over the Krystal; that would be unkind . You are right to delay reporting sound quality changes. My Krystal was a bit up and down at first but settled in well after, I suppose about 50 hours of playing time. As regards the fitting of new components, my dealer's take on this was the opposite of yours. His view was that, if Linn supplied the parts with the Karousel, they should be fitted. As the setup was fine from the start, I cannot disagree with him. David
  3. Dealers are also in competition with each other of course. On niche products (and Linn gear definitely comes in that category), the last thing either they or Linn want is open price warfare. Resale Price maintenance may be illegal in many countries (and in some jurisdictions it may be problematic for manufacturers even to quote RRPs or publish a price list), but an unofficial, tacit (and therefore, I suppose, legal) variant is alive and well in Linn Land. David
  4. I'm struggling to understand why the OP would want to do this. While you are fitting even a second hand Kore, it surely makes sense to spend that bit extra and also fit at least a pre-used Cirkus (and there must be a fair few of those at dealers by now), even if the budget won't run to a Karousel. David
  5. The key word is "preference". In other words, "try this and see how you like it" . Going back to the link posted by @Clavius, I agree that the article is interesting, well-written and informative. But it discusses acoustics rather than psychoacoustics. Acoustic behaviour (measurable) is one thing. How we humans perceive that behaviour (near impossible to measure) is another. That may in part explain why there are a number of "cut-off" frequencies that are thought to be significant. The article concerns itself with the Schroeder frequency (200Hz for resent purposes) and to a more limited extent with the directionality threshold (say 80Hz), which also happens to be the upper limit of the range in which SO operates. Some subwoofer manufacturers (e.g. REL) recommend set up procedures which tend to produce a significantly lower low pass filter setting; 50 Hz would be a typical value. Of course, in the real world there is roll off and roll on to be taken into account, but the situation, as it affects the practical implementation of Hi-Fi systems, is perhaps a bit more complex than the author makes out (though his approach to the subject does have a refreshing note of realism to ir). I think the key here is that changes in lower frequency response do have an effect on our perception if higher frequencies. Anyone who has successfully set up a subwoofer will have experienced that satisfying moment when the whole sound picture seems to "come together", and the aural experience is improved pretty much throughout the frequency range. But, of course, the subwoofer itself is only changing the low frequency response of the system. Even so, our hearing experiences an overall improvement. Pattern recognition may have something to do with it, but that's only a guess on my part. David
  6. Welcome to the Forum, and to this Club. If we we were to laugh, we'd be the fools. Probably most of us here have been through a dilemma similar to yours at one time or another. Incidentally, I'm not sure from what you say which amplifier you have. I might translate "KDT" as "Klimax Dynamik Twin", but AFAIK there has never been a model called exactly that. When you say I suspect that that is because the Kisto is the limiting factor. Your ears must be the judge, but I'd be astonished if you didn't decide within the first few seconds of listening that the current ADSM/3 is a way better renderer and DAC than the Kisto, which is two DAC generations older. I think that you are right to pitch for the ADSM, as the cheaper all-in-one MDSM doesn't really suit your use case (unless you decided to sell off your amplifier). The bad news, of course, is that a new ADSM costs £7,500. The somewhat better news is that you can upgrade any previous ADSM to the current standard, with a new five year warranty for £1,800. I don't know whether that now includes the HDMI 2.0 board upgrade, if you require that (I note that you are currently using SPDIF); the HDMI upgrade on its own is £600. If all you need is the £1,800 upgrade, any second hand ADSM variant costing less than £5,700 will save you money on the new price. Was the ADSM/0 you listened to for sale, and, if so, at what price? If you decided to buy a second hand ADSM now and put off the upgrade for a bit, the ADSM/1 does, in my view, sound noticeably better than the /0, but not nearly as good as the /3, especially at lower playback volume. The /2 is the same as the /1, but has the newer HDMI 2.0 board fitted. As you are considering a DSM, it might also be useful to point out that your speakers are not listed as having been measured for Space Optimisation. That list is usually growing all the time, but it has not been updated since the beginning of lockdown. Linn Support can advise whether your speakers have been measured; if they haven't, @sunbeamgls may be able to help you. I hope this helps. I am sure that others will be along soon to help you some more. David .
  7. @Solanum I agree with Moomin; it's a good bit of investigation.. Did you do a "Report to Linn" after Step 2? Just one more thought, which you'll like, but not a lot . Have you tried Steps 1 and 2 while bypassing whichever switch the DSM is connected to? David
  8. I love Briain's detailed explanations - we learn so much from them. But he is working in a fairly rarefied atmosphere up there in the Scottish hills. I suspect that those of us at sea level would find that what he thinks is "a little trickier" would rapidly turn into a series of nightmares in our inexpert hands. David
  9. Thanks for sharing, BY. The design looks interesting. At (?) €250 it isn't cheap, but it fills a gap between the purely manual devices (such as the AT 6012 I am using) and full size vacuum or ultrasonic RCMs. It is also the only device I have seen that mimics a conventional vacuum cleaner by using both an internal brush (rotating?) and vacuum suction. I'll be interested to know both how effective it is and how easy it is to prevent cross-contamination between records. There's news on my own RCM front. Previously, I reported that I have been sharing a Keith Monks DiscOvery One Redux machine with my friend and neighbour Chris. Unfortunately, Chris will be moving away shortly, and we have agreed that the RCM will go with him. After some careful thought, I have decided to order my own Redux machine. This is partly because I am now familiar with its operation and partly because the machine is manufactured here on the Island and Chris and I have had excellent support from Jon Monks himself for the original machine. The new machine will arrive in a week to ten days (I have been told that it is on the production line). Keith Monks machines are all of the "tracking vacuum" type, in which a small bore vacuum nozzle tracks across the record from the centre of the record to the outer edge, which is a bit weird when you first see it but is actually a sensible use of centrifugal force. The Redux now has a redesigned nozzle and dispenses with the use of the spacer thread which memorably featured on all Keith Monks machines made from the 1960s on. Our existing Redux has been modified to this new standard, which works well.. I shall report developments. David
  10. I think that we have reasonably satisfied ourselves here that careful recording of room dimensions and characteristics is the essential foundation of a good optimisation. Given that the best is almost always the enemy of the good, perfection (whatever that is) is not something to be striving for. Any optimisation which makesthe system sound better with SO on than with it off is a good starting point. SO is more than guesswork. It is heuristic in character, based on the understanding that, in the real world, we can only make things better by trial and error, but we can make things better if we proceed in an orderly fashion. Following a defined process removes the essentially random nature of guesswork (educated or otherwise). As that process is based on respectable acoustic theory, it is reasonable to hope that using it carefully will yield worthwhile results. Linn somewhat emphatically don't agree with you. See https://www.linn.co.uk/blog/want-true-room-correction-drop-the-mic. David
  11. I stay with a dealer who (via the old Linn forum) did seek out my business (with an offer that was very relevant to my needs at the time) and has subsequently done everything he can to keep it. Given that I live on an island with expensive ferry costs, and that a visit to me takes my dealer out of the shop for a day, I don't think it is unreasonable for him to charge for installation visits. We negotiate the charge as a separate cost when I am planning a purchase. And he always seeks feedback on how the visit has gone. I don't think that Linn require that installation costs are included in the price, but they do set dealer markups in their recommended prices which, in many cases, could reasonably include the cost of installation. I think that paying for visits separately helps to keep the dealer's attention and leaves room for discussion on the equipment prices, especially where second hand or ex demo items are part of the purchase, or there is any trade-in allowance. David
  12. Depending on how it's implemented, there might also need to be provision for stepped floors as well. With sloping ceilings, calculating the average and increasing the ceiling absorption a little seems to produce reasonable results. I'd also echo @Briain's plea for the restoration of bass and treble shelves. The user preference slide works quite well in a lot of situations, and I'd always use it before applying a bass or treble shelf, but I still think they are needed in many situations. I don't think that we will see the return of specific mode adjustments; I believe that, in allowing those in SO v1, Linn found that they had created a real product support headache for themselves, and they won't be wanting to go down the same road again. David
  13. Indeed. Much better to quote at least the UK RRP, in my view. David
  14. Ignorant questions. Is Google casting the same as Chromecast, which needs to be attached to a device with full video capabilities? What would be the use case for Google casting from a DSM? David
  15. That was presumably because different pricing regimes operate in different countries. What they did in the webinar (sensibly, I think, given that demand for the MDSM will be quite price sensitive) was to quote the UK RRP and recommend that customers in other countries should contact their dealer.
