Considering simplifying my system... talk me down (or whatever)
Maybe you are telling yourself "simplying" but really what you are feeling is the need for a change, but can’t put your finger on it?Unrelated to audio, I can remember when I got my first digital SLR. I took the film camera out of the bag and put ... 
First order/Time Phase-Coherent speakers discussions
A lesson? High end expensive stuff from companies with sufficient depth to design and program signal processing electronics, i.e. like Harman companies, are doing high end in digital. They may not be making $100,000+ speakers that way, but that is... 
First order/Time Phase-Coherent speakers discussions
There is still some or even a lot of reading on digital if you want to start pushing the limits / doing custom FIR filters, etc.   
Network Switches
I think there are things that can be dismissed out of hand in audio, but many that can't, this would be one of them.I have not read about anyone doing specific matching on ICs / Transformers, but I have to expect the variance is as big in the cabl... 
First order/Time Phase-Coherent speakers discussions
As someone has already done the work, I will simply post that from John Bau. By done the work, someone who has a product on the market and advertises this is what they do. It is not such an advantageous marketing thing these days.And that is only ... 
First order/Time Phase-Coherent speakers discussions
You stated that "why time-phase coherence is only possible with a 1st order filter" ... I was filling in the blanks.3. A simulation of an 1st order and higher order filters with ideal drivers and why time-phase coherence is only possible with 1st... 
BASH and expired patents
They are similar in functionality, but BASH is a bridged topology and Carver's is not. BASH claims theirs is better, lower IM distortion, but it could have been also to get around patents.mulveling589 posts10-30-2019 6:41pmAs far as voltage rails ... 
Bright High End Speakers = Bad Room?
In an anechoic chamber, typically what we are showing is the on axis response typically tailored to be perfectly flat.The room response is a combination of the direct and reflected. Higher frequencies are typically absorbed more by things in the r... 
Bright High End Speakers = Bad Room?
audiokinesis, we may be in agreement and we may not be. A speaker that is ruler-flat on-axis, anechoic chamber, will have a typical room response that slopes off at high frequencies. It is this response, the room response that slopes off that peop... 
Bright High End Speakers = Bad Room?
This is why I specifically stated on-axis anechoic response as opposed to integrated energy response or something similar.  
Is Class D Analog or Digital ?
I should have been more descriptive. A class-D amplifier with a direct digital input to the control stage, would be more akin to a power-DAC. These are often referred to as "direct-digital" or similar. They do not use a separate analog DAC when th... 
Bright High End Speakers = Bad Room?
A ruler flat response on axis only matters in an anechoic chamber and/or listening very close to the speakers. The room response is likely to be much different which is what my post speaks to.I do not think overall that most people consider a rule... 
Network Switches
This is an interesting take, going beyond just power supply noise injection, and considering signal injection. I will throw out some thoughts at you w.r.t. that. Please take them as just that, arguments, not attacks on the precept. Almost exclusiv... 
Network Switches
I am new here and I don't find this argument/post very inviting. As opposed to inviting discussion and trying to get to the bottom of a topic that is obviously interesting to the community, it appears to be attempt to shut down discussion and forc... 
First order/Time Phase-Coherent speakers discussions
I think your conclusion w.r.t. filters may be a wrong conclusion based around the type of filters you were using. Different filter types have considerably different step/impulse response, independent of order.You also have to accept that nothing i...
