| Lightspeed Attenuator - Best Preamp Ever? Atmasphere IOW, as you reduce the volume, **no matter how good the passive is**, you will loose bass and impact. This is why a buffer between the volume control and the interconnect cable is so important; as you reduce the volume setting the bass ... | |
| Lightspeed Attenuator - Best Preamp Ever? Yep, no arguments from me there Paul. If you have less than 2mt interconnects a CDP or Phono Stage with less than 200ohm output impedance (which most are) and a poweramp with 47kohm or more input impedance (which most are), there is no need for pr... | |
| Lightspeed Attenuator - Best Preamp Ever? How to kill a thread "By Grannyrig" Well this thread was going along nicely, until it turned into something personal, discussing the virtues of zero colouration of one resistor in the signal path against active preamps, tube or solid-state with 10... | |
| Lightspeed Attenuator - Best Preamp Ever? Sources these days, esspecially CD can drive (have enough output) by themselves (without the need of a preamp) a poweramp into cliping, there is your strait wire with no gain (the interconnects only). All we need is something so we can attenuate t... | |
| Lightspeed Attenuator - Best Preamp Ever? Knghifi wish he could answer some of my questions. I'm still stuck on " ... is the closest you will get to playing music that's truest to the source (cdp, phono ect), and the truest way to hear the way the recording engineers wanted you to hear ho... | |
| Lightspeed Attenuator - Best Preamp Ever? I will try George's tube test soon.GrannyringIt's not my tube test, it's a well known way of checking for microphonic tubes out in the field among techs without the use of expensive equiptment. You can aslo do the same with tubes in poweramps, not... | |
| Lightspeed Attenuator - Best Preamp Ever? Just to add to my previous post on microphonic tubes, if you hear a bonk in the speaker because of a slightly microphonic tube/s, this in turn when playing music will give and artificial effect of adding ambience/echo to the music, if that your ba... | |
| Lightspeed Attenuator - Best Preamp Ever? If I can take this tube microphonics a step further for those who have tube preamps. Try this little experiment. Take the top off the tube preamp and turn on your system and set the volume control at your normal listening position. Then with your ... | |
| Lightspeed Attenuator - Best Preamp Ever? If the signal/source is poor, yes you can alter, soften,bloat thin out or whatever with an active pre, depending on it's own character of sound, yes a it's band-aid fix as you said.With the Lightspeed Attenuator you hear what the source/signal is ... | |
| Lightspeed Attenuator - Best Preamp Ever? You are right guys the Lightspeed Attenuator (LSA) as you guys have nick named it, is the closest you will get to playing music that's truest to the source (cdp, phono ect), and the truest way to hear the way the recording engineers wanted you to ... | |
| Lightspeed Attenuator - Best Preamp Ever? Apologies to Grannyrig, you did not state the Samson was 100k, I misread the statement you made, it was the Atmasphere you were eluding to. This has got a bit out of hand, because I had mentioned "was the Lightspeed seeing the ideal load".It was a... | |
| Lightspeed Attenuator - Best Preamp Ever? Pubul57 The TRL amps are all SS? Not hybrid?Pubul57 Samsons are all solid state 68k, fet input, dc coupled.Cheers George | |
| Lightspeed Attenuator - Best Preamp Ever? OK now here's the truth from the horses mouth, the Lightspeed was seeing a happy load and Grannyrig check your facts before you double swear it was 100k input. And as I said for it to be over 47k it would have to be Fet input. Below is Paul Weitze... | |
| Lightspeed Attenuator - Best Preamp Ever? Who cried "foul"??? All that was questioned was the the load the Lightspeed Attenuator was seeing into the Samson amp to see if it was working at it's optimum, it is you have tured it into something else.Cheers George | |
| Lightspeed Attenuator - Best Preamp Ever? Clio09 mentioned that "Paul Weitzel told me he does not like FETs or MOSFET" so all I said was "being the Samson is all solid state, that if it's not fet or mosfet input it would have to be bipolar", and any tech will tell you that it's highly unl... |
