Does the choice of amplifier make a big difference with these speakers?
Right now I've got a Yamaha Natural Sound RX-V530 http://www.audioreview.com/mfr/yamaha/a-v-receivers/PRD_133620_2718crx.aspx
I used to have an Onkyo receiver driving my Cambridge Soundworks Ensembles and that sounded awful inspite of the reviews I read that led me to buy that (budget) setup. After a couple years the receiver blew a fuse and (due to my ignorant and over-adventurous attitude at the time) I decided to replace the fuse with some heavy guage speaker cable since I was so sure there was nothing wrong with my Ensembles.
Well, I'm sure everyone can guess the outcome of that move! That led me to buy the Yamaha which I thought would be a great choice b/c it has an impedance selector - 4 or 8 ohms. The Ensembles are rated at 6 ohms so I decided to be safe and set the receiver at 4.
After another year or so that receiver started shutting off - first at high and then even at moderate volumes. When it turns back on it says check speaker cables. My cables are fine - checked with a digital multimeter - no shorts. I wanted to check the speakers themselves, but my multimeter does not check impedance - only basic voltage/resistivity/continuity.
I did a little plugging and unplugging and found that both of the left-channel speakers (satellite and sub) would cause the receiver to shutdown and report cabling problems when plugged in to either front channel. I called CSW, explained the situation and they gave me an RMA number to send the speakers in for repair or replacement.
I was impressed that they were able to pull up my warranty information based on my name and the city I lived in when I made the purchase, but I never sent the speakers in b/c I figured at best they would send me new speakers that sounded like the originals - nothing to write home about. Six months after that the receiver started shutting down with right channel sub connected and now I'm listening to music and movies through a single Ensemble satellite.
I'm really hoping the problem is in fact with the speakers and not the receiver itself. It seems unlikely 3 out of 4 of the speakers would develop shorts (unless they were all from a bad batch with poorly built crossovers or something like that) but it also seems unlikely the Onkyo would start burning fuses *and* my Yamaha would report short problems too.
What do you guys think?
