| The Emperor DAC has no Clothes Lots of interesting comments on this thread. I think theres some truth in Robs observation that dacs in the same price range have similar sound quality. The same thing could probably be said of preamps, amps, and even speakers. The same thing co... | |
| What's up with all those clocks I feel your pain. My system has 4 clocks in series...1. Mac2. Sonos3. reclocker4. preamp/processorThe Sonos was modified so its clock could be slaved to the reclocker. The system has not one but TWO Audiocom Superclocks, one in the reclocker and o... | |
| Shielding components from EMI/RFI... Help please Thanks, Al. I will leave both ground wires in place. There is something else strange to report...I installed a shielded Cat6 cable today, replacing an unshielded Cat5 cable. I expected to hear no difference whatsoever. Much to my surprise, there w... | |
| Shielding components from EMI/RFI... Help please My suspicion would be that the connection from the power supply is connecting the ground on the DC output side of the supply to chassis...You may be right, Al, although the ground wire on the power supply is right next to the power INPUT. Here ar... | |
| Shielding components from EMI/RFI... Help please Question...Looking inside the Meridian G68, I see that the power is grounded to the chassis at TWO points. A ground wire connects the IEC input to the chassis. A second ground wire connects the power supply to the chassis.The unit has been modifie... | |
| Shielding components from EMI/RFI... Help please Thank you, Al, for your help. In light of Jim's advice, I've abandoned the idea of using a dedicated ground rod. Even though I live in Southern California where lightning is rare, there's no good reason to take the risk. It's really no sacrifice a... | |
| Shielding components from EMI/RFI... Help please After more extensive listening, I've concluded that grounding the new enclosures to the Meridian G68 resulted in sound that is slightly worse, particularly in "listening ease" at loud volumes. Here are the 3 arrangements I've tried:1. Enclosures g... | |
| Shielding components from EMI/RFI... Help please Sean - I think my results, if they can be generalized, point to the value of extensive shielding in dac's and cd players, all of which have clocks, and many of which have noisy power supplies. I agree that it's strange that you don't see extensive... | |
| Shielding components from EMI/RFI... Help please Sounds like the Cat6 experiment has produced uncertain results. I've already ordered shielded Cat6 from Amazon, so when it arrives I will let you know if I hear any difference. In the meantime...I can now report that my shielding experiment has pr... | |
| Shielding components from EMI/RFI... Help please Thanks, Sarcher. Interested to hear if the Cat6 makes any difference.I have an update...I have installed 7 copper plates inside my preamp/dac. They are each 16 gauge, or .06", which is fairly thick. I grounded each plate to the chassis. I bolted 3... | |
| Shielding components from EMI/RFI... Help please Thanks, Al. My Cat 5 cables are unshielded. I just ordered some shielded Cat 6.Yesterday I received the materials to complete the DIY projects described in the OP. Hopefully there will be some results. I will report back.bc | |
| Shielding components from EMI/RFI... Help please Thanks, Al. That's what I suspected, but it's good to hear from someone who actually knows something (in this case, both you and Steve).On the issue of ethernet cables themselves releasing EMI/RFI... I have no idea whether my ethernet cables are s... | |
| Shielding components from EMI/RFI... Help please I also use ethernet. My understanding is that most (all?) ethernet protocols employ a variety of error detection/correction techniques that ensure perfect or near perfect data transmission.If that is true, then I would imagine that additional shie... | |
| Where is the attractive audio furniture? Try Room and Board.Bryon | |
| Shielding components from EMI/RFI... Help please That is good advice, Sarcher. I had a similar journey with analog interconnects. After trying a number of different shielded interconnects from well respected manufacturers, I settled on an unshielded pair. As you describe, the sound was more open... |
