**Certainly. Proceed to the site you directed me to. Examine the
following brands and models:

Denon:
AVR485
AVR685
AVR1505
AVR1705
PMA700V


Lets see if you have done your homework, Trevor or if you are just
throwing the usual crap around.

Here's the box sco

Denon:

AVR685 not listed
AVR505 not listed
AVR1705 not listed
PMA700V not listed


The AVR 485 shows plenty of examples of op amps whose VCC supplies are
bypassed, but not decoupled.


**They're decoupled, you clown. The resistance of the PCB tracks and wiring,
in combination with the caps acts as a high pass filter. Get back to me when
you've studied some electronics theory. You supplied one example where a
local regulator was used (the best system, which is usually reserved fro
expensive products), whilst I showed you 25 examples. Stop arguing.

Also very many examples of op amps where VCC is
bypassed only with a small film or ceramic capacitor, and not an
electrolytic. Some examples of no proximate bypass at all.


**Nope. I checked. ALL use electros for decoupling. Every single one. Some
have film caps as well.


Bottom line Trevor, your Denon list, the first one you provided is too
flawed to bother with the rest. Come back when you've done your homework.


**I suggest you ask someone about electronics theory. Every one of the
products listed has decoupling caps on OP amps.
