I have the ground loop going XLR to XLR on my system. I connected the shell of the RCA to earth ground and it solved the problem. You could use an XLR to RCA cable for your audio and then do the same I suspect you can use the RCA input shell to tie the ground as well. I agree it’s a finicky...

What’s interesting is the 1W performance. “Signal to noise ratio (A-weighted filter, for 1W)” Noise and clipping are the two biggest impacts on amplifier audio quality. Since this is A-weighted, it already eliminates theoretical wide band noise. I wonder if this is a result of the preamp’s...

Here’s the reference in case anyone wants it. https://www.dirac.com/news/2019-8-21-dirac-live-bass-management-at-cedia-2019/

Just brainstorming. Since you aren’t dependent on advertising revenue and the need for constant page views and you do have a thriving forum, would it make sense to make ASR reviews like TV episodes with a specific weekly or monthly drop? Conflict of interest and perception of conflict of...

I am not buying, but one thing that would be useful feedback imho is that the grilles should be offered in a color matched manner. Once you get to a certain level of performance, it will be hard to promote the Ascilab speakers as an upgrade to someone who currently owns a Neuman, Genelec, KEF...

One of the reasons I lost interest in ASR beyond responding to threads that I started, is that there are double standards. Many on ASR value engineering achievements when they can be measured even though it is well beyond the point of audibility. We criticize stuff when the stuff does not...

@signalpath You should send a unit to @amirm to test. When an end user sends something in, measurements just get published. When a manufacturer sends it in, you get the opportunity to discuss findings or talk about the way you think the measurements will best be shown...

I just picked up both of these SACDs mentioned here. I haven’t had a chance to listen to them much, but they should be interesting recordings. https://www-phileweb-com.translate.goog/sp/review/article/202503/01/5950.html?_x_tr_sl=ja&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=wapp It’s a new label...

That definitely works for bookshelves and some soundbars use battery packs for their rear speakers which are charged by attaching them to the soundbar. But for high powered active speakers, it’s a different story...

100%. There is a reason Dolby stopped offering Dolby Pro-Logic II even though companies like Yamaha were willing to pay a double license in their CX-A5100 to have PLII and the Surround upmixer with Atmos. There is also the cost of bandwidth, and perceived fear of video piracy which prevents 4K...

100%, yes. You want actives. The frequency response at 86 or 96 dB at one meter is a certain amount of amplifier power. Active speakers do allow frequency response correction, but if you look at impulse or phase, it’s not perfect. See what Dr. Klippel has to say about phase, politely. (It...

Everything is in the -100 dB range… and this is all in the inaudible ultrasonic range? I would be interested to see the phase difference comparison in the audible range.

I don’t know if Dolby, Google, or Samsung will jump on it just to have a bigger patent war chest. For all we know, Lenbrook could acquire the IP and fold it into MQA Labs or the new Auro3D could pick up! One of the tough scenarios for startups are the games the VCs can play. If they know you...

That gives headroom to allow processing without digital clipping.

MQA and QRONO get interchanged a lot. This post also shows you what happens when you apply the QRONO digital filter to NON MQA encoded content. I think this gets to my point that the Bluesound Node’s “forced” use of QRONO is nothing to worry about, if the benefits of low noise (which matters...
