I tried to duplicate this with my own Kora pre amp by removing the power cord during play, shutting of the power supply etc. and was not able to duplicate the problem. I am a dealer and spent some time discussing the problem on the phone with Eadese. His unit was an older unit with different power supply connections and some other differences. This may be the problem as the older ones also had a switch on the back of the power supply unit designed to eliminate ground noise if present when used with certain amplifiers. The new ones have a new grounding scheme which eliminated the need for this switch.
Preamp/Amp impedance missmatch?
I live at the end of a very long rural electric coop line. We have several power outages a week. My main system is Dunlavy V speakers, 2 Plinius SA-100 amps (as monoblocks), Audiomeca transport, Dodson Audio DAC with Audio Tekne interconnects and speaker wire. I use MIT power conditioning.
I owned a Kora Eclipes preamp and loved the sound in my system, but whenever the power was interupted while the preamp was operating, the internal fuses in the Plinius amps blew. After months of replacing fuses (a real pain), I switched to an Alioa preamp. This solved the fuse problem, but I've never been really happy with the sound.
Now I'm considering returning to the Kora Eclipse (newer version). Has anybody got any recommendations as to how to keep the fused from blowing? Could I have an impeadance missmatch? (the plinius is 47 ohm) Are there other preamps that will work better?
