| Can You Get 1,000 WPC Out Of Regular Wall Socket? Al, I found this long time ago searching for power test of 200ASC (Icepower module used in my Rowland 102):"I operated a sample 1000ASP on the bench delivering 350W average of pink noise into a 4 ohm load for over one hour with no additional heats... | |
| balanced preamp Atmasphere, It seems that fully balanced configuration offers benefit of even harmonics reduction at some expense of CMRR. I can understand that it might be too expensive to manufacture to stay competitive at the lower/medium price range but all y... | |
| balanced preamp Atmasphere, We were talking about cost of fully balanced gear. I expressed opinion that in order to get fully balanced amp or preamp you pay more and sacrifice CMRR (since you cannot keep gains equal to 0.005%) - whole thing to remove even harmoni... | |
| balanced preamp Atmasphere, 85dB is decent especially when you take into account effect of twisted pair rejection, in addition to shielding, in XLR cable. In order to match 85dB rejection in fully balanced amplifier gains would have to be matched to 0.005% - not ... | |
| CD/DVD Player Mystery Dirty laser? Dirty laser might be OK for most CDs but too weak for some that have lower reflection. If cleaning the laser doesn't help you can rip this CD and make CD-R. | |
| balanced preamp Atmasphere, If preamps are balanced and differential then at the spot where summing takes place (input of power amp or speakers) common mode interference will appear as signal. For instance, if one leg has gain of 30 and the other gain of 30.3 tha... | |
| balanced preamp Atmasphere, Fully balanced configuration reduces only even harmonics while leaving odd harmonics intact - I'm not sure if it sounds better. In addition gains have to be perfectly matched or common mode interference would get converted to normal mo... | |
| Diamond drivers Steve Mowry says in the article "The Whole Truth About Beryllium Diaphragms: -"For a given geometry the first bending (break-up) frequency is proportional to the material Speed Of Sound, where the speed of sound within a material is defined as the... | |
| Negative feedback Amp=more faithful reproduction? Atmasphere, It make little sense to seek very high DF for better damping (assuming that speaker needs it) when inductor in series with the woofer has most likely resistance of 0.1 ohm limiting DF to 80 even with perfect amplifier. | |
| Negative feedback Amp=more faithful reproduction? Mapman, Woofers have only one invention - lack of suspension (spiderweb) compensated by large diameter voice coil mounted to flat disc in place of dustcap. It makes membranes lighter, faster and stiffer. Midrange (6.5") uses, in addition ferroflui... | |
| Negative feedback Amp=more faithful reproduction? Mapman, That's the first thing I hated - The looks of two small coffins in glossy black (I hate glossy black). Overtime they grew-up on me and now I love them. (It is a little bit like Eiffel Tower or glass Pyramid if front of the Louvre Museum, o... | |

| Negative feedback Amp=more faithful reproduction? Edwyun, this particular design (Icepower) uses Nielsen Karsten multiple feedback. One feedback comes from modulator while the other is from the speaker output. Class D is relatively linear to start with, while output impedance is inherently low he... | |

| Negative feedback Amp=more faithful reproduction? Dracule1, What I'm getting from this is that some amount of imperfection can sound to many people more natural. Difference between natural, pleasing and faithful is fluid. Article was very interesting and thank you for posting it. I would only dis... |
