Changing volume doesn't affect the hiss.
E280 has pre-amp and power amp option, when I press the power amp (main input button), there is no hiss.
Help needed to eliminate unwanted noise from tweeter
Hi all, need your advise to eliminate annoyance "sizzling" noise from speakers' tweeters (close listening range).
I have isolated all the power supply of audio equipment. Then plug in one by one in sequence as following: -
a) Integrated Amplifier - Accuphase E280
b) CD Player - Sony CDP-997 (standby power) - no noise observed from tweeters even my amplifier volume knob is at set to lowest position.
c) DAC - Denafrip Ares II (standby power) - Once I plug in, I could hear the sizzling noise from tweeters when my ear is near speaker.
d) Music streamer - Unplug Ares II, and plug in Eversolo DMP A6, similarly I could hear noise from tweeters.
From the above, could someone pointed me what's wrong with these two (2) units? They are three-prong with ground pin, they are connected to my Novaris Surge Protector multi-gang socket outlet and to wall recepatacle, there's earth/ground continuity.
Your advise will help me to isolate the 'noise' issue for cleaner auditioning with thanks.
Regards,
Auronthas

An interesting findings that the culprit of the hiss... it's the Novaris Surge Filter. I managed to open this surge filter, they are organized in 5-slot, first slot is the SPD (surge protection device), 2-5 slots are twin sockets, I slide out these slots and noticed few 3-pin socket outlets wiring terminals were loose. Thus, I fastened all of them. Then, I reinstated all the slots in original manner. After plugged in all the music sources, Ares 2, DMP-A6 and E280 and tested on both standby and turn-on mode, there's no more hissing noise from tweeter, dead quiet. I am so delightful able to find the root cause finally. |
Thanks @audphile1 .. I am enjoying music now with my new Tacima power conditioner/strip. It’s truly challenge to swap cables, interconnects with eight (8) audio equipment, and then found out the culprit is the surge power filter loose wiring/wire lug terminals... exhaustive work but good experience. |
