| Hum hum hum Disconnected all inputs and I get a distinct hum at high levels on one speaker with just the amp/preamp/speaker connection.... I probably will never play at these levels I think you are saying that the hum occurs at high settings of the volum... | |
| Anticables I would keep in mind the possibility that you might have been similarly disappointed if you had purchased pretty much any other brand of $600 interconnects. Components and systems vary widely in their sensitivity to cable differences, and in ways... | |
| Audiophile fuses - Synergistic Black fuses vs the còmpetition FWIW I have never seen a +/- tolerance specified by any manufacturer of any fuse for either current rating or melting point. What is generally specified by Littelfuse and Eaton/Cooper-Bussman for their fuses, in addition to the nominal current rat... | |
| RCA or XLR iInput Shorting Plugs or Pins Hi Audiobrian,Actually my VAC preamp and amp each have selector switch for preamp inputs and amplifier input. So no shorting plugs needed if I fully understood your remarks. It’s conceivable, although perhaps unlikely, that putting shorting plugs ... | |
| RCA or XLR iInput Shorting Plugs or Pins On many power amplifiers which provide both XLR and RCA inputs the signal pin on the RCA connector is connected directly to the non-inverted signal pin on the XLR connector (usually XLR pin 2). In that situation neither the RCA center pin nor XLR ... | |
| Why are low impedance speakers harder to drive than high impedance speakers I agree with Geoff’s post just above. Also, regarding:Timber77 1-15-2017 No audiophile amplifier will go down in output in that fashion , if its 45 watts at 8 ohms then it should be 90 watts at 4 ohms....If the wattage is dropping then the amplifi... | |
| low power tube amp Doesn’t the tonality issue apply to any amp given the not so flat impedance curve?if my amp is able to drive the speakers without clipping at my listening level, then the tonality problem is the same as with a 200w amp correct? When a speaker’s im... | |
| low power tube amp Also, my amp has a 4-ohm output, but doesn’t that decrease the power rating to half? ie 10wpc? Generally speaking tube amps are designed to provide approximately the same amount of power when a 4 ohm load is connected to the 4 ohm tap as when an 8... | |
| low power tube amp The Focal Sopra 2 is specified at 91 db/2.83 volts/1 meter, with a nominal impedance of 8 ohms and a minimum impedance of 3.1 ohms. Based in part on my experience some years ago with a high quality 18 watt tube amp and 90 db speakers having fairly... | |
| Synergistic Red Fuse ... Hi Dave.I suppose it's possible that there is some relation between the apparently lower melting points of the SR Blacks, compared to typical stock fuses, and the sonic benefits that have been reported. But in the absence of a good technical unde... | |
| Synergistic Red Fuse ... Kedoades 1-14-2017 Hello, I am thinking of trying one of these black fuses. I see some people are recommending that you go one size up on the fuse, just wondering if this is always safe to do? thanks Based on the several reports we have seen in th... | |
| Shindo Montrachet EL34 amp -- can it handle impedance of Snell Type A? I believe the Quads drop to 3.5 ohms or so in the bass and rise quite high in the treble. Actually, as with most electrostatics it is the opposite of that. The impedance of a capacitor decreases as frequency increases, and from an electrical st... | |
| Who thinks $5K speaker cable really better than generic 14AWG cable? Regarding the possibility that audio components can be designed to be insensitive to cable differences, in the case of line-level analog interconnects Atmasphere has described the design criteria which would accomplish that. And he has offered w... | |
| Why are low impedance speakers harder to drive than high impedance speakers I agree with Unsound’s post just above. And while I consider myself to be a "speakers first" kind of person, as he is, I don’t see that as being inconsistent with Ralph’s statements, including: Often people have a preference about tubes and transi... | |
| Power supply hum transmitted to loudspeakers I agree with Cleeds. To make a meaningful test of an amplifier's intrinsic noise level shorting plugs should be connected to its inputs.Many choices of RCA shorting plugs can be found at eBay, by entering "RCA shorting plugs" into its search box... |
