| Is preamp remote volume a deal breaker for you? I would therefore expect that in the case of a short cable, say a few feet long, and if the cable is reasonably well designed and is driven from a low impedance balanced output, that those effects would be insignificant both with and without the t... | |
| What do you think of this preamp design? What we're talking about is a textbook integrator circuit . . . the 1 Meg resistor and 100nF cap are even common values, giving a 0.1 second time constant, equivalent to 1.6Hz. The reason behind the extra RC on the input is unclear, as it doesn't ... | |
| What do you think of this preamp design? It looks overly complex... A very competent solid state line stage could easily be built with about 1/3 the components. The op-amp in the feedback loop looks to me like an outright design problem...The opamp is obviously an integrator (DC servo) u... | |
| Bang & Olufsen Beogram RX2 turntable The motor on the RX2 is electronically regulated, and thus the speed will be unaffected by the operation on the US mains current. It's just the voltage, as HIfihvn states. A simple step-up transformer will take care of that . . . and it can be a s... | |
| How many forms of Jitter can you identify? Many of Julian Dunn's classic AES papers on jitter can be found here, and are IMO required reading on the subject:http://www.nanophon.com/audio/Two big conceptual errors I see very commonly are the assumption that any intrinsic jitter related to r... | |
| New Accuphase Cartridge I saw that too, and thought it quite a brilliantly-written bit of copy! Somehow it by itself doesn't really take any sides in the whole analog-vs.-digital thing, but at the same time nurtures a warm fuzzy feeling for those who might, indeed, take ... | |
| Telephones for Audiophiles? Dont know if any of you have tried the B&O phones recently, but for these or any other high quality cordless phones, can anyone suggest tricks / tips / tweaks / hacks to increase the range?To actually answer your question . . . The BeoCom 5 us... | |
| What the heck is bias anyway? I dunno Trelja, I'm going to have to stick by it. Amplifiers and and cars are certainly different, but the main, general pragmatic, neophyte-level points between bias adjustment and idle throttle angle correlate well:- They both determine the leve... | |
| difference between an active and a passive preamp? Could you explain a little further, though, what parameters of the cable connecting the source component to a passive preamp would interact with the things you mentioned, beyond interaction with the output impedance of the source component that wo... | |
| Is equal gain OK for bi-amping? From a theoretical standpoint, "passive biamping" is really only advantageous when using a pair of identical, direct-coupled solid-state amplifiers that have a low output impedance, especially when they're Class AB or B with conventional unregulat... | |
| What the heck is bias anyway? Here's the classic simplified answer: Bias is to an amplifier what the engine idle speed adjustment is to a car. Set too low, there are performance issues. Set too high, and many cars and amplifiers also have performance issues, and additionally p... | |
| shield to pin one of xlr The proper termination of an XLR connector for a tonearm cable depends on the particular type of cable, and how it's wired at the tonearm/cartridge end. Ignoring rare exceptions like old three-wire tonearms and single-DIN terminations found on B&a... | |
| Karaoke mixer preamp I think virtually everything aimed specifically at the karaoke market is, by definition,going to be cheesy. But there are many small, simple professional mixers out there with exceptional sound quality, aimed at field recording, broadcast, and fil... | |
| How To Route Streaming Music From iPad 2 to DAC? Apple Airport Express will give you by far the most convenient way to do it (wirelessly with AirTunes) -- this will allow you to still use th iPad for other stuff at the same time. Sound quality with an external DAC can be very good . . . way more... | |
| Sooloos vs. Sonos Another alternative that fits your budget, existing wiring, and desire to use the computer for storage and control would be the Linn Akurate DS ... also a solution where the sound quality is minimally dependent on computer setup, DAC jitter reject... |
