| Gain on preamplifier The max output at 30V could mean at an input of 3 volts it clips. 3 volts in and 30V out is a gain of 20dB. | |
| Beware of NAD M3 Fire Hazard Safety caps do fail short, not enough though to create a fault condition a fuse or breaker can clear. RIFA caps in old Mark Levinson gear are notorious for this. If it's the "round cylinder", it is possible that something conductive shorted the po... | |
| Grounding Speakers Just one caution: If that earth connection on the speaker ties the common (negative terminal) to ground then it would damage an amplifier with active speaker terminal outputs if you ground the speaker. | |
| Voltage question Stepping down the voltage is the correct solution. Running it at 120 volts can cause problems... for example if a secondary voltage somewhere inside the unit is, say, 34 volts and there are 35 volt capacitors, then 120 volts on the primary will in... | |
| Voltage question As Eric says... if the voltage range covers 100 to 120 then no problem.If it only says 100 volts I wouldn’t even plug it in. | |
| The Mytek Brooklyn will not be isolated! If the total USB cable length exceeds two meters it could create problems with some dacs. Maybe that extra cable length is to blame. | |
| What is the reason for my speakers having an audible buzz? Most likely it’s the insulation washers around the rca connectors. If the rca connector comes in contact with the chassis you get a buzz. When you touch the barrel of the cable you are reseating the washer and the buzz goes away. Double check by t... | |
| Equi=Core Hum & Other Issues Check both the main panel and subpanel to see if each phase is 120 volts and the neutral to ground is close to zero volts. | |
| Synergistic Research Cable Risers? SR offers a full refund within 30 days, so I would be hesitant to call them snake oil salesmen. If someone offered me, say, a car that gets 500 mpg and said I could have a full refund no-questions-asked if I don't like it, I just may buy it. To sa... | |
| A philosophical question. This is why a subscription to Tidal or Qobuz is worth the money -- you can explore music that you never knew existed or would not go out and buy or download. There is so much at my fingertips that I rarely walk over to my CD rack or access the dig... | |
| Are Bowers and Wilkins speakers overpriced? Overpriced is a personal determination -- would you rather have the product or the money in your pocket? | |
| Tube preamplifier circuits MOSFETs are similar to tubes in that they are operated by voltage swings instead of current. Tubes are iffy and require care and feeding in circuit to keep them relatively quiet and performing to spec. MOSFET's are simple and consistent and cheape... | |
| Capacitors Maybe not. The crossover design probably required the high capacitance of the polarized cap and the designer took into account the high ESR into the overall impedance. Replacing that cap with a lower ESR film may throw things out of balance and ma... | |
| Unexpectedly low volume with Schiit Saga + Vidar You're going from 40 watts to 100 watts, about a 4dB increase. Subjectively, a 10 dB increase in power is what is needed for us to perceive "twice as loud". I hear no perceptive change in loudness between my 200 watt and 100 watt amplifiers at the... | |
| New Breaker Box-Should I upgrade? The electrician discouraging it is your answer. Good tradesmen do not like doing unnecessary work. |
