| Placette RVC vs. Placette Active? 08-08-11: Pubul57 In a proper system, I would choose the Lightspeed Attenuator over any of them (though it does lack balance control).Pubul57Hi Paul, I also do a twin mono L&R volume control version for $35 extra, just thought I'd let you know... | |
| Lightspeed Attenuator - Best Preamp Ever? If you wish to see the measurments at CD playing levels, even better than what I said in the last post, I have posted the Silonex graph and an Audio Precision distortion measurement graph, by the measurers calculations is said to be .0025% only at... | |
| Lightspeed Attenuator - Best Preamp Ever? At line level, at 2vrms which a cdp hardly ever hits, even with peaks, you get .2% of 2nd harmonic which is pleasing to the ear, and as we know with tube amps this can be 10 x this figure. All tech info/graphs and circuits can be found at this sit... | |
| Lightspeed Attenuator - Best Preamp Ever? 07-09-11: DevilboyGeorge,I'm sure that the information I need is listed somewhere in the vast number of posts but could you please tell me what the ideal specs that the Lightspeed would work best in? What output voltage and output impedance of sou... | |
| Lightspeed Attenuator - Best Preamp Ever? Sorry, I should have made it more clear, it's not for more $'s. As it is I'm finding it increasingly harder to keep up supply. At it's current shipped pricing of $490usd it is only viable if the overheads are kept low as I have done, family based,... | |
| Lightspeed Attenuator - Best Preamp Ever? Hi guys, I have a potential future CA distributor, who asked me about the comparison between the Lightspeed Attenuator and the Music First TVC, I remember someone did the comparison and it was very favourable for Lightspeed can anyone give the lin... | |
| Lightspeed Attenuator - Best Preamp Ever? With the Lightspeeds output at worst 7k, this together with a 1mt cable with a max of 100pf per foot gives a -3db point at 75khz, which is plenty high enough and still higher than any cdp noise filtering.Cheers George | |
| Lightspeed Attenuator - Best Preamp Ever? Hi guys, interconnect cables can be a mine field, not just with the Lightspeed Attenuator but with all forms of audio gear. Cables can form a hi frequency filters with their capacitance (pf picofarad)) when combined with the input impedance or out... | |
| Lightspeed Attenuator - Best Preamp Ever? Teak does not shield against rf, it maybe a step forward in glitz, but a step backward in sound quality.One day I may do a remote and have a retrofit scheme for present Lightspeed Attenuators, but it would have to be a quality one, not those chint... | |
| Lightspeed Attenuator - Best Preamp Ever? Hi Paul, I can answer a few points for you.1: Nobody as far as I know uses the NSL32SR2S "S" donates selected versions of the NSL32SR2 which are far more uniform and far more expensive.2: As far as I know nobody does matched quad sets, as this is ... | |
| Lightspeed Attenuator - Best Preamp Ever? Hi James, I'm sure Alex mods the output stage and even the i/v stage of the Esoteric X01 when he does the mods, it is possible he has lowered the gain with his mod, also on inspection they are an opamp based i/v stage and opamp based ouput stage a... | |
| Lightspeed Attenuator - Best Preamp Ever? The ratio impedance between the series ldr to the shunt ldr is what causes the level difference, this is why it's called a voltage divider, but one that can be varied in both planes. EG: If they are at the same impedance you have half volume comin... | |
| Lightspeed Attenuator - Best Preamp Ever? Channel to channel matching using quad matched sets as I do, gives the obvious left/right channel balance (centralized sound image & stagging), and more a more stable i/o impedance. All the other copiers of the Lightspeed Attenuator on the mar... | |
| Lightspeed Attenuator - Best Preamp Ever? Ha!!! Blu-ray, you guys love abbreviating things, like LSA for my Lightspeed Attenuator, every time I see LSA mentioned on the web I hope it my product being talked about but 50% of the time it's the LSA speakers. Down here in Australia we do the ... | |
| Lightspeed Attenuator - Best Preamp Ever? Excuse my ignorance, what is meant by TV/BR? TV? but what is BR?Any source is compatible, so long as it has over 1v out and is lower than 200ohms output impedance. I have customers with tuners, Dat-tape, reel to reel, cassette and phono stages all... |
