| The Physics of Electricity @viridian, Part of my complicated Polish last name would correspond to "Frogman". Kijanki means "tadpoles" (makes me feel younger :) ). | |
| Balanced vs RCA between amp/preamp Balanced gives you better electrical noise rejection (if you need it), but costs more and requires additional circuitry to make it (less is more). I don't have a choice since my current and previous amps have only XLR inputs, but I still apprec... | |
| The Physics of Electricity @williewonka These PS Audio articles are good primer except for possible errors like this:The electromagnetic field is strongest nearest the wire, decreasing with the square of the distance moving out away from the wire.It is not the square of th... | |
| Need Advice on Power Protection/Clean Power I bought Furman Elite 20 PFI and installed whole house surge protector. Furman has strong non-sacrificial under/over voltage protection. It doesn’t lower dynamics since it contains huge inductor and capacitor storing energy for peak demands. It h... | |

| Help ! jimcrane, As I understand it copying to special Audio-CD-R, MiniDiscs or digital tape is legal since royalties were paid on them. In that case you can sell or donate original CDs (you paid royalties twice), but copying to other media like data CD... | |
| Help ! Schubert, Ripping CDs doesn't have to be a tedious job. Just set up the server and when you feel like listening to something place CD in the computer and start ripping. Few minutes later first ripped track will appear in your playback program an... | |
| Fans on amps. I agree, that it has no effect on life of semiconductors while it has some small effect on their performance (Mosfet transistors getting slower while bipolars getting faster). Electrolytic capacitors are affected by temperature. They simply dry-... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong Yes 90kHz is a little better than 60 or 70kHz, but not by much - leaving noticeable phase shift in audio band. I’m not even sure that this phase lag is a problem, since speaker, being inductive at higher frequencies, shifts phase forward. Lamm Ind... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong You’ll just have to look at what Technics did on the SE-R1, no complaints about it becoming an RF transmitter using normal non shielded speaker cable, just praise for it's good sound. Perhaps because they raised frequency response only to 90kHz, i... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong Also it’s not that the higher switching speed alone make for the good sound it gets, it’s also that the "low order output switching noise filter" that all Class-D’s have to use, can now also be taken up 2.5 x higher, this then has no effects now d... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong When class D amp is switching between two discrete levels not the voltage but duty cycle is a quantity of interest and it is linear (no discrete steps). It becomes converted back to corresponding voltage thru averaging (filtering). Voltage gain ... | |
| I went from Class D to Luxman A/AB - And most of what you think is wrong Calling it a digital amplifier is a lot closer to the truth than calling an analog amp. Amplification process is still analog, hence "Analog Amplifier". Connecting amplifier to DAC doesn't make amplification "digital". | |
| Recommendation for specific amp (must have 110 /220V) switch Benchmark AHB2 has auto-ranging power supply. |
