| 24/192? Ghosttrider45...Thanks for the info. The number of options available with new disc media makes it difficult to figure out what is going on much of the time.In my experience TACET DVD-A discs, available from elusivedisc.com, are the best to reveal ... | |
| 24/192? The D/A converters developed for DVD application are 24 bit devices that can run at 192 KHz. When these readily available and relatively cheap devices are used to read a 16bit CD disc and are run faster than the 44.1 KHz data rate of the CD disc, ... | |
| Table speed Belt drive tables, whatever their other virtues, can easily run fast or slow because of diameter error of the drive pulley and/or belt slippage. Of course in the best tables the error is minimal.Quartz clock controlled direct drive tables, whateve... | |
| Physical explanation of amp's break in? Herman, et al....My experience with audio circuitry goes back to about 1953, when we built our own equipment, often from raw electronic parts, sometimes from kits, and also did a bit of circuit design on the side. My bread and butter job, as oppos... | |
| Physical explanation of amp's break in? Whatever...In the missile guidance system business we have learned over several decades that circuits ought to be configured so that they are not sensitive to exact values of their electronic components. It can be done. The necessity for items lik... | |
| Physical explanation of amp's break in? Sean has pointed out that the change which occurs with initial use is a DETERIORATION, and he needs to readjust circuitry to make it work right. Tuned, adjustable circuits (which appear to be what he refers to) can be shifted away from optimum adj... | |
| Physical explanation of amp's break in? Herman....Capacitors that are in frequency-sensitive circuits like a crossover, are selected to tighter tolerances, like 1%. In the usual power amplifier interstage coupling application, capacitors are specd to a much higher value than necessary s... | |
| Physical explanation of amp's break in? Sean...I doubt that the normal changes over time/use of resistor and capacitor values can explain what you claim to hear. These changes are trivial compared with the value tolerances of the components (2% is typical for resistors and 20% is common... | |
| recommendation of a sound level meter Sean...Yes, analog (sorry analogue) meters can be guesstimated to fractional division resolution. When I was in college I had a professor who could read ten decimal places off a 4-inch circular slide rule that he kept in his shirt pocket. The 1 dB... | |
| recommendation of a sound level meter sean...The RS meter digital resolution is one dB which is probably better than you can read with a needle. As I mentioned, the digital display includes a bargraph display which shows dynamics, and is (IMHO) easier to follow than a needle. | |
| ''Hissing'' from speakers....cause ? Tubes hiss. Everything else hums. Good equipment (in proper working condition) is inaudible. | |
| Is vinyl dead ? Rockinroni...To paraphrase George Orwell..."ALL audiophiles are in the "lunatic fringe", but some audiophiles are more loony than others". | |
| recommendation of a sound level meter Edle, or anyone...Why not the digital version of the meter?Except for the readout device (DVM vs Analog voltmeter) it's the same instrument. The digital unit has a bargraph display as well as the numeric readout, so it is easier to read in every w... | |
| Rachmaninov Piano Conerto 2 - Recommended LP? In my recent post "Multichannel discs, and Why" I cite this particular concerto at an example of one class of music that benefits from multichannel. If you have SACD capability, try PentaTone PTC 5186 114...Werner Haas, piano. (Actually, this is a... | |
| Four front main speakers for 2 channel listening? It depends. If you put two speakers, "stacked" one on top of the other, you have made yourself sort of a line array, which has some advantages, particularly with regard to imaging. Put the top speaker upsidedown so the tweeters are adjacent. At on... |
