    Can I wire 3 speakers to a Wiim Amp? More questions

    Mono to all three speakers would be the easiest way, as discussed above.

    Can I wire 3 speakers to a Wiim Amp? More questions

    OK, is the wire to each speaker for a single speaker or is it stereo?

    Can I wire 3 speakers to a Wiim Amp? More questions

    The question is whether the speakers in A are a stereo pair or 2 stereo speakers and is the speaker in B a mono or stereo speaker. And, I would assume they are all 8 ohms (most ceiling speakers are) without any major dips. If they are all mono speakers, then 2 hooked to L and 1 hooked to R...

    Can I wire 3 speakers to a Wiim Amp? More questions

    You can use a impedance matching speaker volume control. You connect your speakers to the box and it presents a 4 ohm load to the amp, which is fine for the amp. You can get them with or without volume control. Niles is the old standard, but Monoprice also has them at lower prices.

    Anyone using their WiiM ultra with a Sonos Arc (home theater setup) to play music?

    I cast (from another program) to a single Sonos speaker and then use the Sonos app to group speakers. That allows the Sonos syncing protocol to keep all the Sonos speakers in sync.

    Are there sound quality benefits in upsampling to 24/192 using the ultra when outputing optically to a DAC?

    One reason to use higher sample rates is to avoid the pre-ringing that comes from a steep brick wall filter. A 22 KHz brick wall filter creates pre-ringing in the 18 KHz range. Some people say they can hear that pre-ringing, but those people are few and far between. The pre-ringing in a 192 KHz...

    Thoughts on A/B testing

    I said I am done with this, but I think it is important to question some our your statements. Kunchur is a physics who does specialized research in audio and acoustics. He is far more than a hobbyist. Hobbyist do not publish peer reviewed papers in Audio Acoustics, complete with 218 references...

    Thoughts on A/B testing

    I am not going to get into yet another long discussion about this topic. It has been beat to depth a million times in countless forums, including this one, and usually ends up in a tit for tat discussion that goes nowhere. My points are simple : Some people claim 1) if the published...

    Thoughts on A/B testing

    The website for the journal should discuss the review process. There are current two types of scientific publications. The old, tradition ones almost always have peer review systems and the publication of an article in those types of journals says that the paper has passed peer review. The...

    Thoughts on A/B testing

    I got a different impression from the video. What I heard was that our hearing/perception system are very sophisticated, much more sophisticated than most people realize, and these complexities need to be considered in addition to the standard measurements like frequency response and noise...

    Thoughts on A/B testing

    Per review for publications done by outside experts, not by the author's supervisor. But, yes, per review is not perfect. But it does show a level of support from other experts in the field. There are a lot of scientific papers published these days without per review. They are often approached...

    Thoughts on A/B testing

    Correct. What the guy on the video is discussing is the contents of Kunchur's paper. The content he presented is published research from an expert in the field. That content should be taken seriously. The "for anyone to take him seriously" comment seemed to imply that the whole content of the...

    The discussion in this video is based on a per reviewed paper published in the scientific publication Applied Acoustics. The author is a professor in the department of Physics and Astrophysics at the University of South Carolina. He specializes in the fields of audio and acoustics and in...

    Thoughts on A/B testing

    This video discusses why out hearing/perception is, in fact, very sensitive and not entirely understood.

    Thoughts on A/B testing

    It is not necessarily a DAC issue. It can be caused by any of the electronics or by the speakers. The amp or speakers are the mostly likely cause. My point was that "That effect indicates that there is more to our hearing that can be determined in a few minutes of A/B testing."
