Kumar Atre Posted May 18, 2010 Share Posted May 18, 2010 I have a Denon AVR-1603 (from maybe 1998) powering a pair of six-week-old Heresy IIIs. I'm very impressed by the clarity of these speakers, but there is a growing amount of noise (a hissing) showing up - even some crackling sounds at higher volumes. I wonder if the speakers are revealing the shortcomings of the receiver, which is to say that its easier for me to believe that its the receiver's fault than the loudspeakers'. Because the noise seems to have increased over the last six weeks, I fear that they may be suffering irreparable damage. Any advice? I'm interested if there's anything I can do with the receiver (some sort of cleaning maybe?), but also possibly in purchasing another. Again, any advice would be greatly appreciated.

wuzzzer Posted May 19, 2010 Share Posted May 19, 2010 The speakers are probably amplifying poor contacts with cables or worn out components within your receiver. Unplugging and then reconnecting all of the cables in your system would be one thing to try. Otherwise your new speakers deserve a new receiver!

4tay Posted May 19, 2010 Share Posted May 19, 2010 Agreed, speakers don't generate hiss. Quote Link to comment Share on other sites More sharing options...
HarryO Posted May 19, 2010 Share Posted May 19, 2010 Try a different receiver if possible. I wouldn't use FM as a test source. Congrats on the HIII purchase. They're my favorite of all the newer Klipsch products. Harry Quote Link to comment Share on other sites More sharing options...
Mallette Posted May 19, 2010 Share Posted May 19, 2010 AAMOF, you just found out what an upgrade you made... Speakers should be good enough to make every other flaw in your system stick out like a sore thumb. Rejoice! Dave Quote Link to comment Share on other sites More sharing options...

Hi Kumar, Congrats on your new Heresys. I'd start by using some contact cleaner on each of the mating surfaces between your receiver and other components. Give the RCA connectors on both the receiver and the source component, along with the RCA connectors on your cables, a good cleaning. If that doesn't clear it up, it's possible you have a bad interconnect cable. Cleaning and replacing interconnects are relatively inexpensive steps compared to replacing receivers, so they make good starting points.

Kumar Atre Posted May 19, 2010 Author Share Posted May 19, 2010 Thanks for the advice - I'll start by cleaning and reconnecting, etc. The question that remains for me is: does the noise damage the speakers in any way, i.e., should I not use them in the interim. Also: I am now interested in a new receiver or integrated amp. The idea of a tube/valve amp appeals to me - having read opinions about their agreement with horn-driven loudspeakers - but I don't know quite where to begin. What other componentry will I need (equalizer, something to alternate between channels)? Do tube amps typically have digital inputs? Would I need an external DAC if using AirTunes? Is using a tube amp to listen to a digital source somehow wrong (ideologically, technically)? Opinions, advice, musings - all greatly appreciated!

wuzzzer Posted May 19, 2010 Share Posted May 19, 2010 Static-y type noise and hum from electronics won't hurt a speaker at all. Extremely loud pops or distortion will. Quote Link to comment Share on other sites More sharing options...

Oh No he is thinking about going to the dark side ! [] Someone hurry up and help him before he looses control... Welcome to the forum, nice choice of speakers ! [H] You were very funny in that movie Kumar, you and that other guy trying to go to the whitecastle. [Y] [] OK just kidding, I know it wasn't you...was it ?
