| Who is using passive preamps and why? Clio, I wish they would allow pictures so I could post a drawing, but you are looking at a series-parallel circuit with the Zin of the amp in parallel with part of the passive. When the volume is all of the way up the whole passive is in parallel ... | |
| Who is using passive preamps and why? hmmmm, can't find where I said 10K was a good match. Which original example are you referring to?. | |
| Who is using passive preamps and why? Even with the volume turned all of the way up the CD player is loaded with 33K ohms and the Zout of your player is only 50 ohms, a ratio of about 700:1. Conventional wisdom says at least 10:1 with higher better and no benefit beyond 100:1. I think... | |
| Who is using passive preamps and why? Pubul, the output voltage isn't the issue, just about any CD player has enough voltage to drive any amplifier to full volume. The problem occurs when the CD player output impedance (Zout) is too high compared to the load it sees which is a combina... | |
| to volume pot or not to volume pot It controls the impedance of the signal running through the cable and keeps it stable. Passive preamps are notorious for sounding thin in the bass and mid bass because they can't control these impedance fluctuations.Uh, sort of. The impedance of c... | |
| Any feedback on the just released Hendrix albums I stand corrected. My $30 was based on what I saw it for at my local vinyl emporium. I see it online for $15.52 at Amazon with shipping. I looked at eBay and some guy is asking $300 for a copy. It's not even a low number, and, oh yeah, you'll need... | |
| Any feedback on the just released Hendrix albums I agree that anything he did is of interest, it's just not thirty dollars interesting. If it's mediocre Hendrix and not something one would likely listen to again then spending thirty dollars on it is a waste.. | |
| Very slight "Hiss" I bet if you stand on your head for an hour you'll get a headache too, but why would you ever do that?In normal use why would you ever press your ear next to the tweeter?I agree with Tpreaveshttp://en.wikipedia.org/wiki/Obsessive%E2%80%93compulsiv... | |
| Who is using passive preamps and why? From a measurement standpoint resistors should beat transformers, but an awful lot of people claim they like the sound of the transformers better. My opinion is either one can sound very, very good if properly implemented and this is one of those ... | |
| Who is using passive preamps and why? Rrog, I'm sorry if you felt insulted but I was merely pointing out that your post had nothing that was exclusive to passive preamps. Everything you mentioned pertains to any system. I didn't point this out to insult you. I brought it up because yo... | |
| Who is using passive preamps and why? Rrog, If you want to say that the overall gain structure of the system must be considered then, yes, in some systems you do need the extra gain you can get from an active so the factors you listed which have to do with how loudly it can play do ne... | |
| Who is using passive preamps and why? no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, I'm not angry. Passionate? okTired of seeing people declare absolutes in a world with so many variables? okAfter so many years on these forums tired of seeing the same things debated over... | |
| Who is using passive preamps and why? I prefer the sound of an active preamp because it sounds like music. Rrog, once again a dogmatic statement that fails to take into account all factors. If you want to say you've never heard a passive that sounds like music then it appears that wo... | |
| Who is using passive preamps and why? Pubul, I see your point, they do have limitations, or perhaps better put they require careful implementation, but that could be argued for just about anything. After years of experimenting I've found that a couple of stages of triode amplification... | |
| Who is using passive preamps and why? Rrog, just because you tried numerous times doesn't mean you ever tried a combination that was suitable for the purpose. There is absolutely no reason a source component can't have an output stage that is capable of driving an amp directly and man... |
