Default High Pass Filtering - How Audible?


"Arny Krueger" wrote

High pass filtering is endemic in audio systems.


What??? ARC, Anthem, Ayre, Bel Canto, Gryphon, Headroom,
Klyne, Krell, Lamm, Mark Levinson, Rogue, VTL all have
pre-amps with frequency responses starting a DC or 1 Hz.


Please consider the whole system. You got speakers with
frequency response starting at DC or a 1 Hz?

I don't have speakers that reach 50,100 or 200 kHz
either, but some of the sited pre-amps can. The ideal
audio system will be transparent to the source content
(straight wire with gain).


BTW Powell, you can post the results of your lab tests
of the ACTUAL frequency response of these products
at your earliest convenience.

Gee Arny, spend $12 on a Stereophile subscription
if you need the validity of test specifications to validate
your poor hearing acuity.


Either that, or admit that you lack relevant empirical
experience with the products you cited. Anybody can
read spec sheets and drop names.

Quack, quack, quack...


It's no secret that if the corner frequency of a high
pass filter is set high enough, it will be audible.


Define your notion of "corner frequency?"


Read any book about electronics. If you have any
questions, quote the book definition it here.

It’s your thesis... stand and deliver.


Listen for yourself and reach your own conclusions!

It's all good and it's all free!


Hehehe... yea, thanks!


Clearly, its all way over your head, Powell.

That’s why I ask questions... to be edified by my
superiors .
