I've been using:
Marazant SR5600
Old Sony Dual 15" Tower Speakers
BIC H100 Subwoofer
HTPC with audio being sent to receiver through Toslink
I recently purchased a pair of PSB G-Series GT1 and a GC1 center channel (GC1 has not arrived yet). I have just the two GT1s and H100 hooked up to the Marazant. I have used MP3s, FLAC, Audio CDs, and a couple of master recoding Audio CDs. HTPC handles all audio output and is done through a toslink.
I am new to higher end audio and I absolutely love the speakers, most of the time. I am noticing very harsh treble at moderate volumes. I tried replacing speaker cables and interconnects. I switched to cords from Blue Jean cable and it made a big improvement but the noise is still present. I know a lot of people say cords don't make a differnce but they did in this situation.
I am not a fan of load music at all. The Marazant starts at -60 and the loudest I have taken the speakers is -20. I begin noticing the harsh treble around -35 which is very quiet, easy to have a normal conversation over.
The treble becomes full of static while the rest of the music sounds absolutely fantastic. It is very sharp, harsh static that only affects treble, cannot be heard without vocals or high tones. It happens on both speakers and seems to be worse on the left channel. I have swapped the cords around and whatever is hooked up to the left sounds worse.
I also get a noise that reminds me of the noises associated with vinyl. Kind of a faint noise that sounds very similar to the needle of a vinyl. This only happens during music playback, it is dead silent between songs.
Obviously I have an issue, $2k speakers should not sound like this. I think it maybe clipping but the SR5600 is rated for 110w@6ohms per channel. Would clipping start at such a low volume when my avr is rated at 110w@6ohms and the speakers are rated at 150w@6ohms?
I'm think its an issue with the SR5600 but I'm not a pro. I have tried everything I can think of and I highly doubt I received 2 bad speakers with the exact same problem. I am open to any suggestions on getting this fixed.
