| Lightspeed Attenuator - Best Preamp Ever? Hi Paul,Yes, there are significant differences. An active buffer stage will provide a gain very close to 1, while providing a high input impedance (to the stage itself) and a low output impedance. A transformer or autoformer will transform impedan... | |
| where do I connect the earth in my pre to? It's not me using the term "earth"; it is printed on the back of the Lamm, which is a unit initially meant to be sold in the US.Yes, I understand. Note that I referred to "what is labelled 'earth' on your preamp." I had looked at a photo of the re... | |
| where do I connect the earth in my pre to? In some countries the term "earth" is used to mean the same thing that the term "ground" refers to in the USA, which in this case would mean chassis ground/circuit ground/ac safety ground (all of which are usually connected together in audio compo... | |
| Gremlins Emerge with Switch to Windows 7 Great! Thanks for letting us know.Best regards,-- Al | |
| 6+ year old pc/os. should i upgrade? OK. The Pentium D was indeed introduced just about 6 years ago, in 2005. It is not the same thing as the P4, the main difference being that the D is dual core, as you realize, while the P4 was single core. The architecture of each core in the D is... | |
| 6+ year old pc/os. should i upgrade? Can you describe the computer system a little further (make, model, etc.)? I assume you are talking about a desktop machine, since you mention the sound card and video card. But a P4-1.8GHz cpu in a desktop machine sounds to me like something that... | |
| Damn Apple..a fence sitter's dilemma This article provides a good overview of the background and prospects for Thunderbolt. The bottom line: It will not be obsoleting anything in the foreseeable future.Regards,-- Al | |
| What is “warmth” and how do you get it? Hi Bryon,... The issue of whether instrument timbre is reducible to harmonic content. I am completely out of my depth here, so will remain agnostic. Let me make sure it's clear that implicit in my previous post (the one with the lengthy quotes fro... | |
| What is “warmth” and how do you get it? Following up on my previous post, I found this excellent writeup:http://www.phys.unsw.edu.au/jw/sound.spectrum.htmlIt appears that I was partly right, but not seeing the whole picture. Some excerpts from the writeup:If you change a sound without c... | |
| What is “warmth” and how do you get it? Learsfool,The basic difference in timbre between a flute and a violin, to use your example, is that one is made of metal and one is made of wood, not to mention the fact that their sounds are created in a completely different manner as well. This ... | |
| Biwiring with separate cables for low and high end Lynne (Arnettpartners), biwiring from two sets of output terminals on the amp will not change the load impedance that the amp sees, relative to what it would see in any other connection configuration.Regardless of the connection configuration, the... | |
| What is “warmth” and how do you get it? ... For a given volume, fundamental frequency, and envelope I can't envision anything other than differences in harmonic structure that could account for differences in timbre, tone, or the basic character of the note.Just to be sure it's clear, I... | |
| What is “warmth” and how do you get it? Hi Learsfool and Newbee,ALL natural harmonics are always present in the natural timbre, so you can't introduce a new overtone that wasn't there before.Let's say that a note includes a frequency component at 1kHz. In response to that 1kHz frequency... | |
| good rca y-adapter I wanted to combine the left and right preamp outputs for the sub downstream of the splitters, in order to only have to run one cable to the sub. But am wondering what that will do to sound quality of stereo signals from splitters upstream run int... | |
| What is “warmth” and how do you get it? Learsfool, as I see it an audio system can introduce harmonics, enhance harmonics, or even reduce harmonics that may be present in the source material.Harmonics can, and to some degree inevitably will, be introduced by the system in the form of di... |
