How many bits, how fast, just how much resolution is enough?

Here's comparison how different analog filter designs affect the DAC transient output, tested with square wave:

The one I use in DSC1 is not Bessel though.

 

Of the DACs I know, at least some Cambridge Audio models use Bessel (Dac Magic).

I was under the apparently incorrect impression that linear phase was limited to first order (analog) crossover filters.

 

Here's what Nelson Pass says:

 

The 6dB/octave and the inverted 12 and 18dB/octave examples yield sums which are quite fiat, and remarkably, we see that the 12 and 18dB/octave cases both yield identical amplitude and phase results. Of all these filters only one, the lowly 6dB/octave crossover has both accurate amplitude and phase response when the outputs are reassembled.

Until a few years ago I owned a pair of Pass XVR-1 active analogue crossovers:

 

 

I spent many months playing around with all types of crossovers. But eventually, the only ones I could live with were 1st order.

In a perfect world we would (/should?) all prefer phase and time coherent speakers but the reality is that the shallow slope of a first order filter will affect frequency and power response and is ineffective at tackling break-up resonances (although you may get away with it by narrowing the operating band of the driver):

 

 

Here's an interesting essay on the subject:

One can of course use tools like Acourate or Audiolense to create room/speaker correction filters that also correct phase anomalies from speaker cross-overs.

 

Acourate can also generate optimized digital cross-over filters.

Talk about wide ranging, this thread has morphed into one covering a myriad of topics.

For me more "qualitative" (by my subjective perception) music cause lesser tiredness during listening.
