| Music First Audio Passive Magnetic Preamplifiers? Hi Paul, your Lightspeed Attenuator chassis is fully shielded alloy, it gets it's RF sink earth via the interconnects. Vibration doesn't come into it as there is nothing to get vibrated as it's passive, even the active led's are immune as they are... | |
| Music First Audio Passive Magnetic Preamplifiers? The Lighter Note is a circuit parts only kit, you still have do all the chassis, rca and ancillaries etc yourself. Uriah did ask me if he could sell matched "pairs" of ldr's on DIYAudio for members and I said yes to that, I do go one further and d... | |
| Music First Audio Passive Magnetic Preamplifiers? I first did the Lightspeed Attenuator back in 1975 but the LDR's were horrendous to keep calibrated I thought about patenting it but with zero reliability what was the use, it still sounded to everyone as the most transparent/dynamic pre they ever... | |

| Music First Audio Passive Magnetic Preamplifiers? Yes the "Myth" this is a blatant rip-off of my Lightspeed Attenuator design, how can one charge $1700 + $300 shipping for just a bit more glitz and a remote is beyond me. I have been asked many times to do a remote model and I figured it to still ... | |
| Slagle AVC Modules & Lightspeed Attenuator The simple way is to just get a source switch box, then you can have your cake and it too. So when you want to get the best out of your system you can still go direct, as I've have proved with my prototype, which does have two inputs with the best... | |
| Slagle AVC Modules & Lightspeed Attenuator Pubul57There is something about the idea of a passive linestage that makes me think it has to be better of doing nothing destructive to the signal, and that in some way an active, any active simply does too much to a signal be as pure to the sourc... | |
| Slagle AVC Modules & Lightspeed Attenuator Pass XA100's are very low input impedance, I think around 12k or 20k this is why Nelson designed a very simple 2 Fet buffer for the Lightspeed Attenuator, you can see it on my Lightspeed Attenuator forum on Diy Audio, it's for memory it's around p... | |
| Slagle AVC Modules & Lightspeed Attenuator I may have jumped the gun and have to appologise.It looks as though your server or fire wall is doing the self editing, as if I try to insert the more than or less than signs (the V's on their side) it does the self edit thing, you guys need to fi... | |
| Slagle AVC Modules & Lightspeed Attenuator OK lets see if this one gets through unscathed. If I could just chime in here about the PRAT factor with the Lightspeed Attenuator. If you have a source (cdp or phono stage) that is less than 100ohms output impedance and power amps that are more t... | |
| Slagle AVC Modules & Lightspeed Attenuator Sorry again, you moderators are nutz your going to blow some ones system up if you keep editing my figures like that, you have know idea what your editing. I'll try a fresh post please leave it alone.Cheers GeorgeCheers George | |
| Slagle AVC Modules & Lightspeed Attenuator Sorry, moderators have edited and stuffed up the figures in my last post.Source output impedance (cdp or phono stage) should be less than 50kohmCheers George | |
| Slagle AVC Modules & Lightspeed Attenuator If I could just chime in here about the PRAT factor with the Lightspeed Attenuator. If you have a source that is 50kohm (100kohm or more input even better) your PRAT factor if anything will be better than ever, it give the impression that your lis... | |
| Slagle AVC Modules & Lightspeed Attenuator Also Paul, wait till you hear the Lightspeed Attenuator with your M60 OTL's. I heard OTL monoblocks 8 x 509 tubes in each with a Lightspeed up their skirts last weekend, I must say it was the most crystalline sound I have ever heard, it reminded m... | |
| Slagle AVC Modules & Lightspeed Attenuator Thanks for the wrap guys, just a note, my prototype that has been powered on 24/7 now for more than 5 years has in fact got dual inputs with a very good gold plated 2amp rated switch the best I could find. Still when I listen test every production... |
