| Dollar to Satisfaction Ratio not met. Probably the main contributor to the problems you are hearing is that the output impedance of the BAT and the input impedance of the DNA-500 are not a good match.Stereophile's measurements of the VK-51SE indicate a sharp rise in output impedance f... | |
| How do you judge your system's neutrality? Mr. T, any measurement instrument ever devised, for the purpose of measuring anything, has (or at least should have) what is commonly referred to as an "accuracy" specification associated with it, notwithstanding the fact that the specification ar... | |
| Another Basic Question about Preamps Yes, preamp output impedance should be much less than power amp input impedance.The commonly cited rule of thumb is a 10x ratio. However, a 10x ratio is truly comfortable (in assuring that frequency response flatness will not be significantly affe... | |
| Re: differences in tuners Yes, there are considerable differences among tuners, in sound quality, sensitivity, and selectivity. Also, I second the previous comment about the importance of the antenna.You'll find a wealth of information, as well as specific comments on many... | |

| True Headphone AMP? Sarcher30 raises some interesting points. A preamp having very low output impedance, and the ability to drive low impedance loads without significant frequency response issues or increases in distortion, should work well into many headphones (espe... | |
| Digital Cable Question At least one site offers two lengths: 12 inches, or 5 meters!! Which apparently are the best lengths for less reflections being a problem.The usual recommendation, if the cable is not very short (less than 12 inches) is 1.5 meters, or about 5 feet... | |
| Digital Cable Question The main difference is that an unbalanced digital cable is (presumably and hopefully) designed to have a "characteristic impedance" of 75 ohms, within a tight tolerance, while chances are that an analog interconnect will not be.A digital audio sig... | |
| Personal Tuner Evolution Presently in use:-- Main System: REL Precedent + Scott LM35 Multiplex Adapter (the best combination of sensitivity and sound quality in my experience)-- Second System: Scott 310D + Fisher MPX100 Multiplex Adapter(aside from the Precedent, the 310D... | |
| True Headphone AMP? 05-06-11: AlmargIf the amp is on a single chassis but is bridged or balanced, so that the black terminals are driven with a signal rather than grounded, you would do the same except that the ground wire would go to amp chassis.Correction: The refe... | |
| True Headphone AMP? 05-05-11: Jedinite24How would one hook up their amp so that it could power a pair of headphones? I have a Hafler DH-220 and from looking at the manual it says it can be used to power a set of headphones. From looking at the Hafler and seeing a lac... | |
| True Headphone AMP? Not sure that using an ordinary amp would be a good idea in most cases. Keep in mind that dynamic headphones typically produce in the rough area of 100db spl for an input of 1 MILLIWATT (0.001 watts).Also, a low powered tube amp (or any other tube... | |
| XLR and RCA interconnects in the same system? Elizabeth, an example of my reference to "reduced sensitivity to cable effects and differences (particularly if the output impedance of the component driving the cable is low)," and note that I did not say NO sensitivity, I said "reduced sensitivi... | |
| XLR and RCA interconnects in the same system? I second the comments by Kal, Kijanki, Rdavwhitaker, and others that a balanced interface can sometimes provide significant sonic benefit regardless of whether the components are internally balanced or not.In addition to the reasons they mentioned... | |
