  1. I wouldn’t mount GIK Gotham diffusers on the ceiling as they weigh a ton. GIK do a 1d diffuser in expanded polystyrene which I haven’t tried. I use Vicoustic Multifuser DC2s which work great and are made of expanded polystyrene - I think the white ones would look good on a ceiling: https://www.thomann.de/gb/vicoustic_multifuser_dc2_white.htm
  2. You said this “Hopefully you like the effect but generally products like that are advised against as they only have any effect at the highest frequencies.”
  3. That was in reply to @alexhwith a very well sorted room who knew exactly what he was doing, but he used tiles which varied in thickness from 20 to 40 mm on top of ceiling tiles. He still got told he was wrong for some reason. Although the ceiling is a first reflection point, the treatment of the left and right first reflection points isn’t the same because they will have an effect on the stereo image in a way that I assume treatment on the ceiling won’t. I have absorbers on my ceiling, but the panels to the left and right have scatter plates so there is some diffusion. It is quite common to see pure diffusers used as ceiling tiles, but less common to see them at the sides, in HiFi listening rooms as opposed to studios anyway. I have put my pure diffuser panels on the front and rear walls with most at the front.
  4. The standard GIK panels use mineral wool. I believe they have a new range that uses acoustic foam.
  5. That sounds like a good starting point to me. My own ceiling panels made a very worthwhile improvement, and were about the same area as a proportion of the total ceiling area, and so you should get a similar difference.
  6. I use GIK panels with the scatter plates option and so they are not pure absorbers, they diffuse although they don’t do diffusion as well as dedicated panels would.
  7. As far as I know the intention of the Gaia design is to reduce the vibrations being reflected back into the speaker - the main aim is not to reduce vibration transfer to the floor.
  8. I use Gaia IIIs in two different systems and I’m very pleased with the results. I also use IsoAcoustics sub woofer speaker stands in the LS50W based system with Gaia IIIs which sits on floor boards. The was notably less floorboard vibration when I put the subs on the stands. Difficult to know what exactly the troll on this thread is arguing about, but for effect like that which can be felt as well as heard it is really quite obvious that these products work, without needing to do time wasting schoolboy physics experiments to confirm.
  9. The panels were installed by Sound Reduction Systems www.soundreduction.co.uk They recommended which panels to use and gave me quotes for eight and for twelve panels, and I ended up going for eight.
  10. This is the front end of the room with four of the ceiling panels in the picture: There are another four out of the picture so they cover the whole ceiling. You can see they are suspended so there is a gap between the panels and the ceiling.
  11. I’ve got eight 120 x 120 cm panels suspended from the ceiling in my large lounge. They were fitted by a company that fitted panels to the ceilings of the conference rooms in the office building of the company I work for - that’s how I found out about them. The panels made a large difference that you could tell just listening to somebody speak in the room before and after. They also improved the appearance of the room. I don’t think bubble wrap or blankets will work as they are too thin and I would expect them to be pretty ugly too.
  12. I assume the meaning of ‘UPnP endpoint’ isn’t clear. It is just a way that a device can control the music playing on a streaming system. Other ways include Google’s Chromecast, Apple’s Airplay and Roon’s RAAT. If a device, such as the LS50W, can use one of these ways of transmitting music tracks it doesn’t matter which app is sending the tracks because the way it is done is standard. So the LS50W doesn’t care if KEK’s app or BubbleUPnP is sending the music because they do it in exactly the same way.
  13. If you buy something from HiFi Collective I think you can be certain it will have been carefully chosen and high quality. I don’t think the Switchcraft plugs are that expensive at about £25 for four anyway - maybe you can save money by buying from eBay but there is the chance of ending up with a shoddy knockoff.
  14. The easiest RCA plugs to solder that I’ve used were these black Switchcraft ones: https://www.hificollective.co.uk/phono_plugs/black-body-gold-plated-plug.html The hardest were KLE Absolute Harmony plugs that were easy to melt if you allowed the soldering iron to linger too long - out of the twelve I soldered I managed to wreck one of them and fortunately I managed to get a single replacement when they are usually sold in fours.
  15. This thread has actually inspired me to take a look inside my P10 at the components at some time. I've had a lot of fun changing the caps and resistors in a couple of my speakers recently, and playing with changing the P10 could be interesting if it made as large as an improvement. As long as the changes are reversible, it doesn't matter if they end up being a disappointment.
  16. Suppose you simulate your room, but then how do you know if the predicted sound will be to your taste? How do you add the effect of diffusers to the simulation as they are a very important part of tuning a sound field to your taste? As far as I know listening to the room as you add treatment is something even the most experienced professionals need to do. Of course they are better at doing it than amateurs like ourselves, but I don’t personally see a fancy piece of software being able to replace a process of learning by doing that everyone needs to go through.

    No problem - thanks for filling it in!

    How do we know where you’re coming from, if you don’t list your kit in the ‘Wigwam Info’ entry of your account?
  19. I don’t think it is likely that you can overtreat a room with bass traps. The GIK traps, such as Tri-Traps, have an option called a ‘range limiter’ which cuts the absorption at higher frequencies and improves the absorption at the bass end. For the panels at the first reflection points the GIK panels can be ordered with ‘scatter plates’ which add some diffusion to the panels. I also use pure diffusers of which my favourite is the Vicoustic Multifuser DC2, and I have some GIK Gotham Quadratic diffusers too. So probably the best summary would be to not overdo panels which only absorb.
  20. I would surprised if the actual DAC had changed much from the previous one though. It’s only a few unusual DACs like Chord that have a delay problem.
  21. The processing delay in DACs varies a lot and if the latest LS50W has an HDMI input designed to be used with a TV I assume KEF have thought about it and ensured there isn’t a problem.
  22. Yes, it is a high quality router running the OpenWRT OS. The LS50W manual does give a fairly high recommended minimum router speed spec and it is quite possible the home hub doesn’t meet that.
  23. I use my LS50Ws wirelessly and never have problems with High Res music. I use a Linksys WRT1900ACS Dual Band router and use the 5 ghz band, it runs MiniDLNA for my music library using a hard disk attached directly to the router.
  24. To minimise the chance of things going wrong. I don’t use any of the libraries for listening, as I use iTunes only for creating trees of folders with the music tracks in them. The AIFF and ALAC directory hierarchies are on the iMac are copied to various disks in Linux ext4 format which I use for listening.
  25. I’m not convinced I ever got 40db of gain with my P10 with whichever valves I tried. I’d like to try it with an MC cart and a step up sometime. Are the mods only available as a commercial service then, rather than being a DIY thing?
