| Pop Sound in my speakers when driven loud from studio recorded CD sources. Al... thank you again. I think that we are understanding the terms "compressed" and "spacious" in the same way in terms of dynamic range. It’s just that I handle the volume issue with each, differently than most, I guess. The truth is, I enjoy the... | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. Erik, I did try blocking the ports, but no change. In fact it may have made the phenomena worse... hard to tell. | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. Kanjit, The covers on the Hales are nearly impossible to remove. | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. Al, Thank you! This is an education for me. I think I understand your detailed explanation. In summary, you are saying if I were to rule out some electronic or mechanical failure in either the Marantz or the Hales, it is most likely inadequate amp... | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. Al, Thanks for reviewing your original response. Most here seem to think that the amp is clipping. Is that what you are describing by saying: "...Given the 180 mv sensitivity of the Marantz receiver and the 2.1 volt maximum output level of the ... | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. Yes, they're ported. What will blocking the ports do?? | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. Hey... I got an email that member "almarg" posted to this thread, but I don't see the full post here. The partial post I got in the email is below. Almarg, if you are out there I would like to know your full response. Not sure why it didn't get... | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. Filter capacitor: Not likely. They were all replaced & upgraded (along with a lot of other internal components) in the Marantz’s restoration process, only a couple of months ago. The unit was also extensively bench tested before it was returne... | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. This is all helpful... So, the output of the DAC is <50 ohms. Is that relevant? | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. I have another Marantz... the 2245. Also fully restored and putting out about 58 wpc. Probably not a good for testing with the 8 ohm Hales. | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. The Cambridge CXC CD Transport does not have the DAC in it... it's just a transport. I'm running all digital signals through the Cambridge DAC Magic Plus. It's a digital converter and preamplifier (I'm not using the preamplifier part). Output im... | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. Thanks all! Simao: Cambridge Audio CXC Dedicated Transport. It says "Output Impedance" <75 ohms. | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. Doing some research on clipping. My issue does seem to be (and sound like) amplifier clipping. Only specific 'sharp' sounds seem to cause the speaker drivers to shutter. Anyone want to confirm this? The amplifier in the Marantz receiver does not ... | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. As far as amplifier clipping is concerned. A recently completely restored Marantz 2275, which was bench tested at about 85 wpc is what the Hales speakers are working with. I don’t know enough about clipping to know if it possible that my amplifier... | |
| Pop Sound in my speakers when driven loud from studio recorded CD sources. I’m afraid there is no rattle or anything loose when I shake the speakers. I would revise my description of the sound though, from a "pop" to something more like a "fart" or "burp"... sorry folks, that's what it sounds like ;-). |
