| Won't preamps become obsolete? Blptwp...What is a TVC? I am guessing that it is a multitap audio transformer. I don't understand your comment about superiority vs a resistor divider. It was a great step forward when interstage transformers went away, and here you are puting a t... | |
| AMP for Panasonic XR45 A slight clarification...the Panasonic has six channels of amplification, but the LFE (subwoofer) channel is not one of them. It has center channels both front and back. It does output a subwoofer line level signal which requires an external amp. ... | |
| "Polyamping" A Look to the Future or Fancy Fad? 4yanx...Of course the idea of an amp for every driver has been around as long as I remember, and I go back to the early 50s. However, your invention of the term "polyamplification" is a great leap forward! | |
| Bass Question - should LP range be so different? LF is DRASTICLY attenuated when the record is cut (for reasons mentioned above)and DRASTICLY boosted on playback. Just a little error in this process can significantly affect LF playback response. Also, extreme LF is usually "blended" to mono, bec... | |
| Won't preamps become obsolete? More than 20 years ago I scapped the preamp in favor of an outboard phono section (PS Audio) fed into a Matrix multichannel decoder (Lafayette SQ W) which was probably the best matrix decoder ever. It provided source switching, gain, and volume co... | |
| Logarithmic Frequency response graphs Duddley...A Logarithmic scale shows DECADES equally spaced...100, 1000, 10,000 etc. Octaves would be 20, 40, 80, 160, etc.A Log scale is used when the quantity being plotted behaves in a Logarithmic way. If you plot such a quantity on a linear sca... | |
| A shocking reminder Another way to deal with the spark problem is to hold a key or coin in your hand, and draw the spark to that instead of your skin. The spark will still happen, but you will feel nothing. This trick is handy to know for all the other metal things a... | |
| Good automatic TT's I have a 1980 vintage Sony PS-X800, which is linear tracking with biotracer (servo controlled) arm, and it works to perfection, audiowise and functionally. The X800 is rare and expensive used, but similar Sony linear tracking tables without the bi... | |
| Plasma TVs and center channel speakers Just an idea, but a plasma display is a big flat sheet of glass that would reflect sound very well. Someone should make a compact audio driver designed to sit just below the screen and aimed back at the glass, not out at the audience. ("Boseian").... | |
| Vibration Problem Sounds like you need to relocate the player. Even a small change might make a big difference, as you might be located at a point of room resonance. Another thing you might try is to borrow a different player. Yours might not be up to snuff. All th... | |
| Vibration Problem How do you know you have a problem? | |
| Best Isolation Device for Speakers? Theaudiotweak...Have you measured, or even calculated, the motion. I am not sure that you are correct about that. But so what? Any rocking motion of a 100 pound object will be at a very low frequency. So the tweeter moves around a bit. Well, so do... | |
| Tweeters facing in or out ? The physical distance between woofer and tweeter causes the sonic axis of the speaker system to be angled. (The ubiquitous MTM driver array avoids this). So, by positioning the speakers at an angle, the (small) effect of having the tweeters inside... | |
| The Klipschorn Ecclectique...and there is nothing like a horn midrange/tweeter to reproduce a trumpet or trombone! | |
| Magnepan 1.6 vs Magnepan MG-1 Gmood1...Of course you could biamp the Maggies, but your costs would include another power amp as well as the crossover. I don't know if the particular crossover you referenced is suitable. I would suggest the Audio Control Richter Scale, which gi... |
