| Marchand Audio The original Bose idea (before they went commercial) was to make a speaker with deliberate roll-off beginning at a very high frequency (I seem to remember 200 Hz) and correct it electronically. As sean says, GOBS or SUPERGOBS of power were necessa... | |
| Question about SQ "Good" is a subjective term. They will sound different. There is a significant amount of out-of-phase signal (between the two channels) so there will be increased ambience and sense of space. I play some SQ LPs through Dolby multichannel matrix lo... | |
| Inactive speakers in the room...any effect? Sean...Your point about subtractive differences is very well-taken. The best known example of this is that a performance hall has very different acoustic characteristics when it is full of people vs when it is empty.Of course speakers function as ... | |
| Balanced connection/amplification for phono? Hagtech...A balanced line can be implemented with a two terminal source by leaving both the source wires ungrounded and providing a ground reference through a pair of resistors at the destination input. This configuration was used for powering AC ... | |
| FM/AM versus Analog versus Digital The Stereo FM signal is transmitted, not as Left and Right, but as Sum and Difference. The Sum signal is the Mono signal that can be received by an old FM set that is not stereo. The difference signal is carried above a 19KHz marker tone that acti... | |
| Inactive speakers in the room...any effect? Sidssp...Yes I agree that in close proximity to the active speakers they would function much like passive radiators (which, by the way, some people think are a bad idea).I can't do that particular experiment because the walls behind my three MG1.6... | |
| Inactive speakers in the room...any effect? I would be delighted to participate in such an experiment if there is anyone near western Mass who is interested. An audio club perhaps? | |
| Questions about Toslink's FYI....The "typical" loss for a fiber optic termination/connection is on the order of 2dB. Two of them, so as to insert a switch means 4dB. When you factor in the loss of the switch itself you will end up near the 6dB to be expected from a splitte... | |
| Inactive speakers in the room...any effect? Believers...What you are saying is that a "room treatment" device having only about 1/2 square foot of active area has a significant effect. If this is so, why don't the room treatment merchants design a box with a passive radiator (or an active d... | |
| The absolute best and worst-sounding CD you own ? Spatial quality of the recording is very important, particularly for multichannel stuff, where it central to the purpose of the disc. I will compare two Multichannel discs, one a Sony Classical SACD of violinist Hillary Hahn playing a concerto, an... | |
| Questions about Toslink's Sean..."There comes a time in every program to shoot the engineers and get on with the job". | |
| Balanced connection/amplification for phono? Is there a problem with single-ended phono pickup connection? Not that I know of. Why solve a problem that doesn't exist? (Well I guess it's just for fun).The floating vs balanced thing did occur to me, but if you tie together two of the four pick... | |
| Aragon 4004 mk2 vs Adcom 555 mk2 If the toroidal transformers are stacked that could explain the disagreement. By the way, think that the Aragon amp costs more than twice the Adcom price, so it ought to be better.My Adcom 5503 (like a 5500 but with three channels) is hooked up to... | |
| Aragon 4004 mk2 vs Adcom 555 mk2 Kool39...The photo I saw of a for sale 4004 showed one toroidal transformer. Pop the cover and take a look, or admit it doesn't matter :) | |
| Balanced connection/amplification for phono? For a wire run as short as that between the phono pickup and the preamp the benefits of balanced lines would not be significant. Microphones have low level output, like phono pickups, but are often used with very long cables, and I bet that some m... |
