Hello,
It is my firm opinion that HiFi Tuning fuses are very synergistic with our amplifiers, Spectron Musician III SE. For my ears they clearly and without any question remove "gray noise" across the Spectron from high frequencies to low - making sound much more "liquid" and involving.
It is rather well known that signal transfer function of the electrical signal will change rather dramatically when you move it from one conductive lattice to another and thus results I hear make theoretically good sense.
I do not hear more clarity, increase in soundstage or other things many people claim but for Spectron owners who can afford these amps its worth while to buy them.
Moreover, as a service to our customers, we made arrangement with the distributor for some "Spectron" discount - for details you can e-mail at [email protected]
I would add that as a service to our customers, we made "Spectron discount" arrangement with the distributors of other assessories which per my and my beta users opinion improve sound of our amplifier.
Hope it helps - at least to Spectron users
Simon
