| Lightspeed Attenuator - Best Preamp Ever? The long answer is yes, you can get a slight compression with the Lightspeed Attenuator if the input impedance of the poweramp is below the industry standard of 47k ie: 5k to 30k, because it will be being slightly loaded down. If it is at or above... | |
| Lightspeed Attenuator - Best Preamp Ever? Dave is using it the way the first Mk1 Lightspeed Attenuator was designed. This is a series resistor with an ldr for the variable shunt to ground. This is still better than any potentiometer, but when I compared it to the MkII Lightspeed Attenuato... | |
| Lightspeed Attenuator - Best Preamp Ever? Clio09: What exactly is an array of 48 optically controlled resistors and why can't my LSA have this feature? ;)Clio09Not too sure Tony, could be 48 1% trimming resistors to go with the quad unmatched ldr's, which in my opinion would detract from ... | |
| Is no preamp the best preamp of all? 08-26-11: DaverzI'm aware that I'm losing information when I use digital attenuation, but how does this translate into what one hears that is different that what one hears when an analog volume is lowered. Saying that one "loses resolution" is not... | |
| Lightspeed Attenuator - Best Preamp Ever? An interesting little snippet for those of you who own or have built a Lightspeed Attenuator, this will give you maybe some bragging rights. Not only does the $28k DarTZeel NHB 18-NS preamp have a form of Lightspeed Attenuator controlling the volu... | |
| Modern Linestages "08-25-11: Liguy: The perfect linestage can be imagined as simply a wire with gain. If you do not need gain a passive preamp will do. So, you ask what about matching impedances? Well a simple buffer can be used. Enter the First Watt B1, a passive ... | |
| Modern Linestages Grannyring: George, I like your passion and I do see things differently it seems :Grannyring Nope, no passion here with this, it just Ohms Law, Kirchoffs Law, and the maths that goes with it. The passion comes as a result of listening to the music... | |
| Modern Linestages TBG back a few posts http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1313773451&openfrom&51&4#51is the way one would make sure he/she has properly implemented a passive.Cheers George | |
| Modern Linestages Grannyring you go on that a good active preamp can mystically make a system sound "better", yet you deny the fact here and in other posts that it will be coloured or adding distortions to change this sound for the "better" You cannot have it both ... | |
| Modern Linestages No that implies that a correctly implemented passive will be true to the source, just like a direct source to poweramp connection is the best you can get. It's up to you to get the best source you can. Then if you have to spend $15,000 -$35,000 on... | |
| Modern Linestages "Charles1dadYou could certainly conclude also that the passive units are`nt passing the"complte" signal,thus there`s some degree of subtraction of musical information.Charles1dad"This statement is not correct and only valid if one has not implemen... | |
| Modern Linestages "08-22-11: "UnsoundWhile I understand that passive pres are more system dependent than active pres, I find it interesting that some would suggest that simpler is better and yet choose a system that doesn't maximize the potential for a passive pre.... | |
| Modern Linestages The secrete to having the perfect passive attenuator without losing or adding anything to the sound of the source (being true to the source) 1: Is to make sure the sources ouput impedance is 5 x or less the attenuators input impedance.2: To make s... | |
| Modern Linestages Active preamps are to me a dinosaur left over from the analogue days, when one needed an riaa stage in the preamp and then another gain stage to get the voltage up to the input sensitivity of the poweramps they were to drive. Today's sources cd, t... | |
| Placette RVC vs. Placette Active? Clio09 (Antony) Just ordered one.Cheers George |
