| iPod VS Beosound 6 Hi Cwlondon . . . No, I don't think that the Beosound 2 supports WAVs, but I've never tried it. It came out at a time when a huge, expensive SD card was 512MB, so uncompressed files were considered way over-the-top for portable use. Also it's batt... | |
| Loudspeaker 'Back EMF' Assuming the most conventional (emitter-follower) output stage, then yes, energy that's applied at the amplifier output will affect the current flow through the output transistors. If this wasn't true, then the amplifier would have an infinately-h... | |
| Loudspeaker 'Back EMF' Hi Amfibius . . . Dazzdax is correct in stating the classic analysis of a bipolar transistor's operation, as being based on the current flow from the base to the emitter. I happen to agree with Douglas Self's assertion that this is quite a useless... | |
| How do autotransformers affect sound? Is the only reason many other [tube] amp designers don't do this because the autotramsformer is another component in the signal path? What is the trade off?The big tradeoff is cost. And weight. Which is the same as cost. Oh and did I mention price... | |
| iPod VS Beosound 6 I have actually had the opportunity to directly compare a Beosound 6 directly with an iPod Nano . . . and the Beosound 6 is definately a big improvement in sound quality when using the same files and the same headphones. It's battery life is also ... | |
| Cassette decks....reliability and build quality... Just about any cassette machine that's 15-20 years old will require a little bit of service - the rubber parts simply dry up with age. So the simplicity of a machine counts for quite a bit when it comes to its performance these days . . . the numb... | |
| Who likes LATIN JAZZ? Pianist Bebo Valdés (Chucho's father) recorded an album a few years ago with the flamenco singer Diego "el Cigala", called "Lágrimas negras" . . . I cannot recommend it highly enough. Incredible subtlety of expression in a medium that is still fun... | |
| How to replace bulbs in McIntosh MX130? I was an authorized Mac warranty servicer when the MX130 came out, and if memory serves me correctly, all of the bulbs are stuck into grommets in the metal plate behind the glass panel, and are wired with bi-pin connectors. You still need to remov... | |
| Can an amp overdamp a speaker? In the purely hypothetical sense, no. Damping factor is like distortion . . . in absolute terms, there are specs that are better and there are specs that are worse . . . in the case of damping factor, higher is better, and in the case of distortio... | |
| Why do amps sound different? Hi Atmasphere . . . I'll mock up the speakers this afternoon and see what happens. It has since occured to me that I will need to in both cases null out the effect of voice coil inductance(s) on the measurements. I think that by calculating the EM... | |
| Why do amps sound different? Okay, so I am a little jealous of your AR-3s. Mine went away during one of the audio-gear purgings that accompanied a cross-country move. I do have fond memories of the way they sounded in a bedroom system running off of a cheap Knight 6-watt tube... | |
| Why do amps sound different? Atmasphere, I owned AR-3s (identical to AR-1 except for mid & tweet) for many years, in fact I have some of the dog-eared original documentation right here . . . the only thing I see about a recommendation for the amplifier is "25 watts minimu... | |
| How to install a 120 Volt Cooling Fan? You might check out the products from Active Thermal Management -- www.activethermal.com. Their stuff seems kinda expensive for what it is, until you get it set up and running . . . they're extremely quiet. They will also spend the time with you o... | |
| Why do amps sound different? Hi Atmasphere . . . my main point is that hi-fi speaker designers simply do not consider an amplifier to be anything other than a voltage source, and that they never have. Further, it seems obvious to me that amplifiers have historically been inte... | |
| Why do amps sound different? Well, Cyclonicman, legend has it that James Lansing, immediately prior to his untimely death, wrapped a piece of Alnico V in a largish bath towel and "went postal" on the electronics staff at Altec . . . But seriously, they did it by designing sp... |
