| Lightspeed Attenuator - Best Preamp Ever? hat i don’t like is even more limitation with Lightspeed to have just ONE input. It meant to be like that on purpose, because it eliminates the "source selector" switch which is another lightweight potential distortion causing contact taken out ... | |
| Should I eliminate my preamp? It's always been said by audio designers as a gauge of how good a preamp is since the mid 1900's, when separates (preamp & poweramp) entered into audio, that saying is: "The best preamp should sound like a piece of wire" ie: a like a direct... | |
| Lightspeed Attenuator - Best Preamp Ever? chakster Nelson designed a buffer for the Lightspeed Attenuator over 10 years ago on diyAudio so my Lightspeed customers could drive some of his low impedance (10kohm) amps with it, here it is. Later he called the B1 buffer. https://www.stereo.ne... | |
| Lightspeed Attenuator - Best Preamp Ever? Australian JLTi Funny, but the cabinet of my JLTi phono stage looks exactly like the cabinet of the Lightspeed device. I know Joe very well, he used the same Hammond case after he saw my Lightspeed. The phono stage is a simple opamp riaa input ... | |
| Lightspeed Attenuator - Best Preamp Ever? In the beggining of this thread @clipsal mentioned that First Watt B1 killed his Lightspeed Attenuator in terms of dynamics. This could be true, in most systems the Lightspeed is a great match just like many tube pre's are, this could have bee... | |
| Should I eliminate my preamp? If you have a solid state source like a CD player, quite often it has a coupling cap at its output What Ralph mentioned about coupling caps above is not relevant these days, as nearly all solid state sources have been direct-coupled for years, ... | |
| Should I eliminate my preamp? I like 10kohm pots as passives, as the can be driven by just about any solid state source, just some high impedance tube sources have trouble, and being 10kohm as a voltage divider passive they have the lowest output impedance at worst (mid possit... | |
| Lightspeed Attenuator - Best Preamp Ever? @chaksterYou sent me a PM for info PDF's ect, but for some reason I can't return to you via Agon PM with my email address in the answer as this is the only way I can send you all the info. So you have to email me on georgehifi@optusnet.com.au.Chee... | |
| Should I eliminate my preamp? The OP was asking about getting rid of the preamp in the case when the DAC has a volume control. In that case, there is no downstream volume control, and no need to provide a low impedance buffer for the interconnect, as the amplifier will take c... | |
| Thiel CS3.6 and PrimaLuna jafant8,056 posts04-03-2018 10:13pmI would have sold the PL. Same, and kept the Thiels and got the right amp for them, as they can sound very good.Cheers George | |
| To bridge or run conventionally Bridging amp raises the wattage quite a bit, but that’s where the advantages end.1: Distortion goes up, 2: Output impedance is higher (damping factor lower), which means bass is not as controlled.3: The ability to drive below low impedance’s takes... | |
| Gotta love Nelson Pass I ended up with original First Watt B1 buffer preamp No problem the B1 buffer is unity gain, which Nelson 1st designed to be a (no name), buffer for my passive "Lightspeed Attenuator" preamp so it could drive one or two very low input impedance am... | |
| Gotta love Nelson Pass Yeah the MkI was straight passive all the way, the MkII was passive all the way till 3 o’clock, after which it slowly became active.Nelson introduced this MkII for very low gain amps like some of his, and very inefficient speakers <84db, that n... | |
| Gotta love Nelson Pass One of Nelson's favourites it seems that he thinks highly of, was the Aleph L preamps, really different because it takes the best of both worlds and joins them together. It's a quality passive pre, but as the volume goes higher once it gets to 3 ... | |
| What position is your balance control set at and why? Thanks for the responses. I have switched cables and speakers around but still the right channel will light up. Mike If you’ve done all of this as well as amp/source left for right, and it’s still the right, then it’s your room causing it.Cheers ... |
