Yes, good point Arny. I'll see if I can get the phase graphs up...

So they obviously use a slow roll-off together with minimum phase.
In terms of modern trends and fashions, I agree that minimum phase and
slow roll offs come together,
but if I remember what I learned in filter design class, not so much.
For example any Butterworth filter is

I think the term parachronistic may be more in tune
Parachronistic :) thats it , i know a some folks that ridee motorcycles
. In the 50 and 60 and possible early 70 these where designed as actual
vehicles nowadays it's all about brand recognition and image and look
and feel for many of them . Not a practical thing to commute with .

Yes imho there is a risk that this is audible the only way to get proper
hf response with this player is to use hirez material or maybe upsample
your cd stuff :) what is the hf drop at 13khz or 15khz ? That 20k is
gone down -5dB can bother young audiophiles but thats does not

You're welcome! It was a fun night of measuring and thinking about what
I wanted to say about this piece of equipment after playing with it for
the last couple months off and on.
I think the Pono saga has been a fascinating one to watch and comment on
over the last few
