| What is your best kept secret in mid-fi? Invest in discs and LPs that are made using the very best recording and mixdown techniques and equipment. Although such media usually is more expensive than the average product, the resulting audio quality, even when played through a "MidFi" syste... | |
| Harry Weisfeld Was Right All Along Skating force is only one of many critical adjustments necessary for a pivoting arm, most of which can only be optimized for one location on the LP. I finally decided that you can never get them all right, so I went to a linear tracking arm, which... | |
| what this site needs ... I have a spelling checker, it came with my PC.It plane lea marks four my revue, miss steaks I ken knot sea.I've run this poem threw it, an Yule bee pleased two no.It's let her perfect inn its weigh, my checker tolled me sew. | |
| What do audio shops need to do to survive ? My suggestion...separate the shop from the club house. Invite people to come in and listen and debate to their hearts content in a separate listening room which requires a small membership fee for access. I have pity for the poor salesman who is t... | |
| Is less than 24 bits worth it? My first CD player, a Mission unit, had only 14 bit D/As, (oversampled) but was vastly superior to contemporary Sony units which boasted 16 bits, so I agree with sean (for a change). That being said, and all things being equal (which is not always... | |
| 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. |
