    Article: A New Listening Room Part One

    It is about time difference of direct sound and reflected sound. 6 feet traveling difference (also applies to sides) is the minimum for our auditory system not to confuse direct with reflected so a 3 feet wall distance gives 6 feet back and forth but more if quite better!

    Can I Run Romex Wire Between Joists In Photo?

    Why not use BX I.e. metal clad wires instead of NM (Romex). Should have much better noise rejection as it is twisted and screened and rodent proof. I have to renovate my house which still has a lot of post (knob) and tube wiring and that is terrible considering safety and electrical noise issues (single spaced wires). At least for my listening room I am planning 10 or 8 awg (not much cost more if one does not get audiophile grade).

    Innuos Zenith SE MkII

    I am just testing Qobuz streaming to my Devialet (was waiting for it for years). I can use Qobuz web player on my Macbook and that has great UI. Alternatively I was able to stream via my Zenith (ethernet in and USB out) and it works well and sounds beautiful but the user interface via iPeng on my iPad is just terrible. Are there better ways to control the Zenith? Innuos said they will develop their own control app but I have not seen anything mentioned recently.

    Article: A New Listening Room Part One

    I see a mayor issue with room refections coming from the sides and 45º ceiling focusing a lot of acoustic energy to the center of the room. I had a listening room with a vaulted roof with a radius equal to the apex of the room and focusing all sound to the centerline of the floor and the acoustics were horrible. When I installed a suspended ceiling with a much greater radius the acoustics got pretty good. I guess one needs to disperse reflected sound and try to avoid focusing it to the listing area.

    Qobuz in US: When?

    another month and still no date

    Innous MK III Shipping in August

    I own a Zenith II driving a Devialet 250Pro. The Devialet has also a Spotify connect option which is connected to internet via Wifi. The other option is to use the Zenith with Spotify (ethernet to Router and USB to Devialet). I expected the direct WiFi connection to be worse than the wired connection via the server but that is not the case at all. So at least with mp3 (320mps) I think the server is obsolete.I am not using any higher resolution streaming service (not liking Tidal's catalog and Qobuz is not yet available for me) and but at a higher bitrate stream maybe WiFi will be not as good.

    My Class D amp is beginning to suck

    Did you look at recent weather of S Sweden to N Germany

    What size "LISTENING ROOM" is ideal

    Besides low frequencies room size plays also a role at higher frequencies. Direct sound and reflected which arrive within around 50ms will be merged into one by our aural system (resulting in rooms specific distortions). In order to distinguish direct and reflected sound the distance the reflected sound has to travel has to be minimally 6 ft further than the direct sound, easy to achieve in a larger room but not in small rooms. If a loudspeaker is very directional (i.e.less reflected sound) that is less of an issue (one of the design features of Kii 3 speakers). In order to get proper stereo imaging the reflections have to be symmetrical.

    i listened to them in the Manger room but was not at all excited. I would not blame the Mola Mola but the whole setup, the speakers (I had Manger MSW before and I like their basic concept a lot but I feel these speakers need improvements) and the music presentation. So no idea about the sound quality of the Tambaqui, disappointingly.
  10. good to know that the most interesting part of audiostream - MUSIC got reborn. I thought their April 1st video/joke was a desperate attempt to show that they are not obsolete, not realizing the decision: they are
  11. I listen today to the Hugo TT2 and was very impressed. I had a short conversation with Rob Watts and he has no firm US price. He said that it does not approach the sound quality of Dave (and that is not only about computational abilities but also about part quality and output stage) but clearly above Hugo. It has enough output to drive sensitive speakers and that what he did during the development phase.

    Reflections help to generate the "sound stage" of a room but there must be a time difference between direct sound and reflected sound of at least 5ms. I think the best is to have reflections with the necessary time delay but somewhat diffused and attenuated, too much absorption kills the room!

    For a proper stereo image the first reflections (sides and back) need to be identical (left or right) but is does not need to be a rectangular room (but much easier to model)

    I agree with you the room is the most important part except when using headphones and that may be the reason that headphones gained so much popularity (and they max out at 50K). The one thing I completely disagree with: plasterboard is definitely not the best wall system (even with 2 layers) as it has very specific resonances. Any light wall system is reflecting high frequencies but absorbing lows compared to masonry walls and that is the reason that in the US where drywall is much more used loudspeakers are tuned for more bass response.

    Why!? Please Tell Me Why!

    Lots of shrink wrap is very amateurish, so why one would think the rest of the design is efficient?
