| Strange ground loop...? Bob - I asked since I've never had coax interconnect. Grounding shield on both ends is really bad, using shield as return is even worse. In addition coax cables, used in video applications, have not the greatest copper since at high frequencies si... | |
| Amplifier hum - normal? See this circuit:img.villagephotos.com/p/2003-5...The only 1000V diode is 1N4007. 1N4001 is only 50V | |
| Strange ground loop...? Bob - what do you mean by "coax interconnects"? Are you talking about digital cable? | |
| Strange ground loop...? "I don't get it... at all. What gives? If it's a shielding problem, then shouldn't configuration A-B-C-D also work just as well?"Shield should be grounded on the receiving end (in my opinion) so your configuration D-C-B-A suggests that terminals C... | |
| Why gold? Shellie - I don't have experience with wall outlets but it is a different application since current flow is involved. In case of interconnects there is a very little current.Audioquest plates interconnects with silver for the best connection. It m... | |
| Does anyone or does everyone pay retail price? I bought retail Rowland 102 and Benchmark DAC1. Both of them have 5 years warranty but only for the first owner.Buying new provides always newest revision of the gear. Buying used Benchmark might end-up getting older unit with thin sounding op-amp... | |
| Why gold? Shellie "Gold has a warmer sound, silver more air and detail- all things considered"- That's what I heard but it applies to material of the wire and not the thin plating of connector. Audioquest uses silver since gold is not a very good conductor ... | |
| Amplifier hum - normal? Gbart Thank you - that was very informative. | |
| Amplifier hum - normal? "A lot of modern amps have toroids, which are more prone to humming and buzzing as a result of DC on the power line."As far as I know Toroid is very quiet compare to non-toroidal transformer. In addition is more efficient because of low stray magn... | |
| Thinking of moving to a Headphone system, thoughts Djembeplay - "to be able to share the music experience with others." - I feel the same way.I have Sennheisers HD580 (same drivers as HD600) and don't use them. Cord is one issue but I just don't like music inside of my head. My 2 speaker stereo th... | |
| Thinking of moving to a Headphone system, thoughts Some headphones have physical sound "crosstalk" between channels to provide 3d imaging. In normal speaker reproduction sound gets from right speaker to your left ear with delay. There are computer sound cards drivers that can imitate this delay cr... | |
| Can "Digital" damage my gear? Mlsstl - I'm probably paranoid but digital offers new way of destroying speakers and even amp in addition to good old ones. It just seems strange to me that one can have amp and speakers destroyed by just playing defective song.Class D amps have o... | |
| Strange ground loop...? "If the cable is coax, the shield connected at both ends of the cable."Bob - I was talking about interconnects. | |
| Can "Digital" damage my gear? Mlsstl - I asked because I checked data sheet for Icepower 200ASC used in my Rowland 102 and it shows that full power blast of 20kHz will damage amp (Zobel network) in 20ms and 20W oscillation will do the same in about 1s. This would imply I would... | |
| Strange ground loop...? IC shield is grounded at one end only (if it's RCA). Try to reverse one that gives you trouble. |
