| Eliminating hum 01-03-15: GrannyringIf a power cord would have a short to the chassis would'nt that trip a breaker in the home?Hi Bill,The purpose of the AC safety ground connection (which is what a cheater plug defeats) is to make that happen. Since equipment ha... | |
| Current limit onset definition? Hi Plato,I'm not sure that you read my comment accurately.The point to my mentioning those ridiculous wattage numbers was to illustrate that, as I said, "the 60 amp figure ... is **NOT** [emphasis added] representative of anything the amplifier wo... | |
| Current limit onset definition? The 60 amp figure is the maximum amount of current the amplifier can supply into a very low impedance (probably a short circuit, i.e. zero ohms) for a very short period of time (probably a few milliseconds). It is not representative of anything th... | |
| Eliminating hum 01-02-15: BojackUsing cheater plugs is completely safe and often effective. Don't let the underwriter of your homeowner's policy see that post :-)Assuming the equipment is in good physical condition, so that there is little risk of an internal sho... | |
| Help me improve Rega P2 Thanks, Marty (Viridian). It should be noted, though, that the DB Systems kit, or any other similar kit, can only add capacitance, not reduce it.But we tend to focus on those things that we can measure, rather than those that we can't.True enough,... | |
| Help me improve Rega P2 Correction to my previous post: FWIW, I just noticed this somewhat ambiguous statement in the text of the manual for the Blue Point No. 2:Note: If your receiver or pre-amp has capacitance loading capabilities, a Sumiko high output moving coil cart... | |
| Help me improve Rega P2 Thanks, Mesch! I've seen numerous indications over the years that load capacitance recommendations for moving magnet cartridges are based on the total of all capacitances between the cartridge pins and the phono stage input (inclusive of the latte... | |
| Help me improve Rega P2 If you choose to upgrade the cartridge keep in mind that you should consider how well the load capacitance the cartridge would see in your setup matches the cartridge manufacturer's recommended range of load capacitance. Your phono stage has a rat... | |
| Can you recommend a simple Tube pre amp? P.S. to my previous post: By connecting the speakers in the manner I described (two speakers in series paralleled with another two speakers in series, for each channel), you would most likely not be using long runs of + and - conductors that are i... | |
| Can you recommend a simple Tube pre amp? I would suggest the Antique Sound Lab Line Two DT, which uses one 12AU7 tube and costs $450.A few years ago I used its predecessor model, the Line One, in my system while my main preamp was down. It performed very respectably, and of course its so... | |

| Bi-amping Pass X.5 matches X.8 / XA.8 / X.5 / XA.5 My present power amp is X1000.5, I think it is enough for many speaker.Wow! That's for sure!I'd just leave well enough alone, unless you feel the need to upgrade the speakers or something else in the system.Even though all of the Pass amps are spe... | |
| Preamp w/ Single Line Input. But I have DAC and CDP I'm wondering if anyone makes a simple outboard switching box which would connect to the line stage on my preamp, so I could plug both the DacMagic and the CDP into the box, and then change sources at the box?Yes there are. A number of years ago I... | |
| Bi-amping Pass X.5 matches X.8 / XA.8 / X.5 / XA.5 Regarding vertical vs. horizontal biamping, see this post, which is written by a noted amplifier designer.Also, while it might be possible to obtain reasonable results using four identical monoblocks, I agree with ZD that it would most likely make... | |
| XLR vs RCA P.S: For examples of what I described in my post just above, see the output circuit of the Bryston BP4 preamp, schematic here, and the input circuit of the Audio Research VT100 power amp, schematic near the bottom of the page here (click on the im... |
