Hello group. I need some opinions...on a very difficult question:
So...after "unsuccessfully" using, the C658; to drive active Dynaudio Excite X14As (and I can't be sure, if my dissatisfaction with the sound...stemmed from the C658, its' balanced-outs; or the Dyns themselves); I went back, to a passive set-up.
I was going to move the C658 along...as the whole reason, behind an all-in-one unit, such as this; was
to have ONE box, and active speakers. With the experiment failed; I fell back, into former habits. Auralic Aries Mini, DAC; modest IA (Musical Fidelity M2si) and passive Dyns (EMIT M10s).
Well...before moving the C658 along; I decided to try it, as fixed
source (using single-ended ICs). As I'm sure you all know; when you set the source up, to be fixed; by default...it's -20db. To me...fixed should be 0db; unless you need to go lower, because of sensitivity...and therefore, not enough flexibility at the volume control.
So...I set my BluOS; to fixed, and moved the output...to 0db fixed. Well...ISSUE!
I don't want to say, that it was immediate
or anything; but...at some point, soon thereafter...the sound got "funny". And then...I noticed the 'mute' indicator, on the M2si; starting to flicker. I IMMEDIATELY turned the amp off; but...when I went back to troubleshoot (changed ICs, SCs, and amps)...here's what I found:
One speaker, was "shot"; no sound output, at all. And the other, was only outputting from the Tweeter. I'm at a loss
There was no, bottoming-out of drivers (no...I was not playing, unusually loud at all); no "pop", or even physical damage...externally
...to the drivers, whatsoever. MF Dealer has confirmed, the 'mute' indicator...typically has to do, with pre
-amp as opposed to power-amp section.
I've owned a TON of equipment; but, have been lucky enough...to have had very few issues, with kit. But...my best, educated guess: feels
like a "burned" resistor...in a cross-over. "Protection" maybe...from what the speaker perceived, as a "threat". The hard question is: what
, is to blame??
MF dealer, wants me to try...another pair of speakers; to test, for warranty repair. I do have another pair of passive speakers; but as I told him...I'm hesitant. I don't want a situation, where it's like "yup; it blew-up...a 2nd
pair of speakers. Testing successful"
He said I could send it to them, for testing; and they'll take it from there...but. What about my speakers!!?? Dyn dealer has said...even though they're under warranty; no dice.
Any thoughts, would be appreciated. I don't post this here...because I think, the C658 is to blame. Only because, it was
part of the equation; I assume you are all, also experienced 'philes...and, to see if perhaps anyone does
think, setting the fixed output to 0db, was a bad idea.
