    Attenuation should be clarified as different to pre-amplification

    What sort of passive pre are you even referring to ? Low level listening with high sensitivity horns is catered for in the link by adjusting the start circuit to be silencing volume commencement where you require Any loading additional on the shunt circuit of a unknown type of passive pre...

    Attenuation should be clarified as different to pre-amplification

    Hi Don Would you like to try it in your audio system ? Whilst your comments apply to other prior efforts, all the points you advise on are solved. I can refer you to a subjective review here: https://www.stereonet.com/forums/topic/563813-latest-passive-ldr-attenuatorpreamp-kit-build/ Your...

    Attenuation should be clarified as different to pre-amplification

    Always without involving any contacts. once within the chassis, There is then no audio degradation from wiring and switching inputs or involving volume wiper contacts. Other methods such as resistance potentiometers traditional since the mid 1960's sadly have none of the good audio quality...

    Attenuation should be clarified as different to pre-amplification

    In my opinion a important aspect of audio reproduction is being missed, by not properly recognizing attenuation as being different to (pre) amplification. The preamplifier introduced as early as 1955 served a purpose , when there were no line level standards. Today's line level sources as a...

    It is a folklore quoted saying, inferring that gain causes unwanted distortion, and it would be preferable if a straight wire just had amplifying capability. It though is quaintly possible. if we use instead the word maintain instead of gain, the first of these, the electronics property of...

    Not a issue if as i do, if you make your own. Particularly when they are not connected :)

    Totally agree, designs that get everything right have a philosophy biased toward subjective appreciation. Those involved designing and soldering might as example be well versed in listening to live acoustic music, as well as having ability of comparison to best available recordings. This can...

    Conventional passives Yes can be tailored to not adversely load the source component, Most passives though don't take the next step sadly being reliant on way over simplistic design where usually a potentiometers fixed value, rearranges all the excitement of what is actually possible. The...

    I have over 15 years experience with encapsulated audio purpose LDR's, ( different to open face types ) the rich harmonic spectrum you refer to above, is not the LDR itself, rather a statement ( if it occurs ) of the mistakes being made, in powering the internal LED. I have also built many...

    It remains passive volume controls are compelling

    It might be easier to just distance yourself as far as you can from the block of text altogether. For example stating passives cannot control the flow of current is just a asking for can of worms, as in partnership with circuitry either side they obviously cause current to pass, which is the...

    Your All Time Favorite Preamplifiers?

    So pleased that was not your own block of text, as it contains so many errors and misinformation. As example there is no amplifying device that is entirely linear, as as soon as you add power to a circuit you add either very small partially acceptable, or indeed unacceptable distortion...

    But sadly adds reactance, returning a quarter cycle later to the circuit. Resistance types have, as a result better linearity with audio signal

    With a well designed passive, true there is no added coloration from added by gear. Rather there is the same drive and dynamics as the music was recorded with, ..exactly as it should be. Passive types are many and everything should be considered.

    Yes they can, you can have all the dynamic content with utmost clarity you require, if you allow the shunt resistance to be independent of the series, so two quite different curves. This allows to adjust or shape the shunt resistance so as never to load the source component. Lower volume is...
