DAKIOM products - your thoughts?

[MD]

I tried one on my DAC ouput by A/B left/right channels with a mono
recording (one side using the device- one side not) and not only was it
obvious to hear a difference but I like it.

Any thoughts from the group?

(I haven't bought one for my amp because it's a tube amp)

Hmm......a lot of talk about unstable NFB amplifiers, something which
shouldn't be happening in a well-designed amplifier.

Their website isn't very helpful with technical details, the best I
can make of it is that the unit provides a constant impedance in
frequency ranges where a speaker might deviate from its nominal
impedance.
IOW some kind of Zobel network, which should be included in a
well-designed amplifier.

If it works for you, enjoy!

Looks like a nonlinear supressor of high frequency signals.

Bizarre.
They assume the amp or source emits an (RF) error signal which is
caused by instability of the output circuit.
A variable series tuning circuit is then used to shunt the detected
frequency to ground by switching the capacitors in said tuning
circuit.

Considering the amounts of RF noise that some CD- and DVD players
emit, it may indeed be audible on non-stable amplifiers and/or
amplifiers with poor RF rejection at their inputs.

I maintain my opinion that they won't do anything with (EMC-wise)
well-designed audio components.
