Did you blow or burn the tweeters? The reason I ask is that, if you are serious about either of these two speakers, you always run the risk of repeating the same damage, regardless of power ratings and amp capability. If you need to listen at 95 dB or above (permanent ear damage is a certainty), make absolutely sure that 1) the speakers are rated to play that loudly given the volume of your room and 2) that your amp won't be clipping at the output required to drive them to such levels. Remember, dynamic peak requirements at any given moment at high levels can overburden the power supply of even a Krell, and, if the speaker receives even a momentary DC, it is likely to cause a coil burnout in one or both speakers.
Newby Q about impedances etc.
Hi,
I'm a longstanding audiophile-wannabe, but I have very little actual knowledge.
The system I've used for a long time is a Krell KAV 300i into Dynaudio Contour 1.1s.
The Krell is fed through a Chord Hugo into a Microzotl2, a tube headphone amp that also doubles as a pre-amp. (Most of my recent listening has been on headphones)
Anyway, the Dynaudios are damaged and I want to replace them.
I like the sound signature, and I have a small listening space, so I'm considering the Confidence C1s, which have the following impedance profile:
Sensitivity 85 dB (2,83 V/1 m)
IEC Power Handling 170 W
Impedance 4 Ohms
Or, the KEF Reference 1:
Amplifier requirements 50-200W
Sensitivity (2.83V/ 1m) 85dB
Impedance 8Ω (min. 3.2Ω)
The Krell is kind of old, but it delivers 150W/ch into 8 ohms or 300W into 4 ohms.
Is the Krell powerful enough to power the Dynaudios? It seems like it should be, but I want to make sure. I found reviewers saying that it shouldn't go full-power into 4 ohms for extended period. Of course, my listening isn't going to be at full power, but I want to have headroom as well.
Finally, I'm going to be auditioning these speakers, but I expect them to sound different in the store than they will at home. Anyone have any experience or comparisons between the two?
Thanks a lot.
