| Question For My Electrical Expert Friends I'm not sure there is much of a difference electrically between running a splice with wire nuts and plugging in an additional 8 ft of extension cord, ASSUMING the extension cord is the same or higher gauge than the Romex. With the extension cord y... | |
| rack mount ? I would put it under the power amp only. You want the coolest air feed the highest power component, and you don't want hot air leaving the power amp feeding the low voltage preamps.So I would place the preamp/selector switch at the bottom, followe... | |
| Accessory Wall Wart Removal Ideas? The problem you have is the need for a plurality of various low power needs, some of which are AC, but some wall warts are DC as well, depending on the device and manufacturer. You may need to have all these electrically isolated from each other (... | |
| Battery backup Computer UPS systems are not good for audio components because most of them produce square wave AC when on battery backup, as opposed to low distortion sine waves normally present on the AC powerlines.The square waves are highly distorted and have... | |
| sub playing by itself You hearing just low bass or high frequencies as well?If you are hearing highs and lows, then the RF is getting into the sub electronics after its low pass filters. A sub should not reproduce anything higher than a couple hundred Hz because there ... | |
| Strage problem - power lines amps /preamp noise For those using a computer UPS (like an APC) connected to your audio system, REMOVE IT!.Those APC units (and most others) produce square wave AC when they go on back-up, which produces a lot of high frequency garbage you do not want in your audio ... | |
| Bryston VS Cambridge Audio I don't have direct experience with Bryston power amps, but I have compared the analog outputs of a Bryston BDA-1 (connected digitally to a CA 840C) with the analog outputs of the CA 840C on the same CD. Both the digital outputs and the analog out... | |
| recommendations for quality line volume control I know you wanted something really cheap, but just in case you cannot find what you want, Goldpoint makes some very nice variable attenuators. The SA-1 is the simple stereo RCA interconnect version at about $300. Very high quality units (I have a ... | |
| Capacitance loading for AT 150 mlx cart Al:Not to worry. This should not be a problem because the physical layout of the system w/ attenuator is not much different than the stock system without it. The attenuator plugs are short (about twice as long as the standard locking RCA) and conn... | |
| Tubes vs Solid State If you can live with the practicality issues of that ARC 600 (ie size, mass, heat generation, tube life, etc) and cost (isn't it about 10x the JC1?), then go for it. For that kind of cash, I would have your dealer install it in your home for a tra... | |
| Troubleshooting Linn integrated Does the amp have a time delay on power up that cuts off the outputs? Sounds like something in that circuit is failing when the amp gets warm and disconnecting the output. The pops may be DC offset voltages the appear on turn on.Provide some more ... | |
| Impressions of PS Audio GCPH Swanny:I'm just getting back into vinyl (after 30+ years), so this is a "starter" phono preamp for me. I use Parasound line (JC2) and power (JC1) amps and up till now have only had CD sources (CA 840C with a Bryston BDA-1 D/A).I considered the Par... | |
| Solid State Pre-Amp: OK to Use With Tube Amp? If your pre-disposed towards tubes, by all means get a tube power amplifier. But they are not "high current" devices by nature. A 60W power amp of any design, will not produce the transients and dynamics of a much higher power amp at higher sound ... | |
| Boron Cantilever and Ruby Cantilever, Why Ruby? With respect to Be, its the oxide(s) that are toxic. For years and years the electronics industry commonly used BeCu (Be copper) alloys in connector pins and relay contacts. But, as with lead (solder), our big brother EPA and other regulatory agen... | |
| Cartridge upgrade for $600 With respect to a MC, what about an Ortofon X5 MC? I know it comes in an ugly red body, but its got a good reputation and the output is HO MC at 2 mV. Its $550 at Needledoctor. I think this might be a better choice than a 2M BlackI was considering... |
