| Digital output or Analog output from Blu Ray playe If you intend only to use the HDMI, component and/or optical & coaxial audio outputs, and NOT it’s analog outputs .... Jim, component video is analog, and therefore those outputs utilize dac's in the player (for video, not audio -- as you no d... | |
| Lightspeed Attenuator - Best Preamp Ever? Good point. The prongs which can be seen peeking out in the photo of the charger kind of look like it's probably USA-compatible. And the three adapter plugs it pictures further down the page are obviously not for the USA, which would seem to imply... | |
| Lightspeed Attenuator - Best Preamp Ever? Is there a Lithium battery supply you would recommend?I don't see any reason why the one George linked to above wouldn't be a good choice.Best regards,-- Al | |
| Gremlins Emerge with Switch to Windows 7 Can anyone please tell me how to restore the audio?Try doing a Windows "System Restore," under Start/All Programs/Accessories/System Tools/System Restore (or else enter "System Restore" into the "Search Programs and Files" box under the Start butt... | |
| Lightspeed Attenuator - Best Preamp Ever? Re batteries vs. wall-warts, perhaps the reported sonic differences are due to voltage differences? I realize that the Lightspeed contains an internal 5V regulator, but perhaps differences in the "12V" input voltage result in different internal op... | |
| Lightspeed Attenuator - Best Preamp Ever? George, note that the issue is not whether or not the volume control will have to be used too close to the bottom of its range. The issue is that even with the volume control set to its maximum position, a substantial fraction of the power capabil... | |
| Lightspeed Attenuator - Best Preamp Ever? So, yes there is a slight loss in max power, but do you think it would be relevant? My guess is that it would not be a problem, especially considering this statement by Jult52 in the other thread:My power amp has a continuous rated output of over ... | |
| Lightspeed Attenuator - Best Preamp Ever? Paul, I'm not certain but I suspect that the reason for the Atma-Sphere S30's high sensitivity number may be that it reflects the voltage DIFFERENCE between the + and - signals at its balanced input, which would be twice the amplitude of either si... | |
| Relate sensitivity/impedance to speaker efficiency The Dali Helicon 800 is a 4 ohm speaker with a listed sensitivity of 89.5. I see the units shown on the Dali website are 2.83 V/1 m. According to what Almarg is saying this would correspond to a sensitivity of 86.5 for a 1w input - is that right?Y... | |

| Relate sensitivity/impedance to speaker efficiency A point which can be important to keep in mind is whether the speaker sensitivity is defined with respect to an input of 1 watt, or with respect to an input of 2.83 volts. 2.83 volts corresponds to 1 watt into 8 ohms. So for an 8 ohm speaker, the ... | |
| Uncommonly long RCA IC cables? Basically you want low capacitance and good shielding and noise rejection. How "low" is "low" will depend on the output impedance of your preamp at high frequencies. If your preamp's specified nominal output impedance (which is probably a reasonab... | |
| What is “warmth” and how do you get it? Mrtennis 02-07-11: So, you are saying that a tube amp would have a different frequency response than a ss amp, when driving an electrostatic speaker.Yes. The ss amp will produce a brighter and more extended top end than the tube amp with an electr... | |
| What is “warmth” and how do you get it? ... When I think of “warmth,” I tend to think of a sound that is “intimate” or “immediate.” In other words, I think of a high ratio of direct to indirect sound, which would typically correspond to listening to a live event from a relatively close ... | |
| What is “warmth” and how do you get it? The output impedance of an amp has to do with the damping factor.True. Damping factor is usually defined as output impedance divided into 8 ohms.It has no relation to treble response.Not true, in the case where speaker impedance is significantly d... |
