| Musician's Challenges Segovia wasn't the best technician. You can hear string buzzing, unintended delays etc. Whole new generation of guitar players including David Russell play without single buzz (poorly pressed string). Two links below show not only Sharon Isbin bei... | |
| why dsd Famoej, Absolutely - if you're satisfied then don't spend money. On the other hand 16/44.1 processing has its own problems and that's why engineers introduced new schemes. SACD is DSD and carries more info. Whole thing started with new types of DA... | |
| Speaker imaging Sound from each speaker travels to both ears with different delays creating depth of image. There are headphones that have feed-thru from one side to another while some headphone amplifiers simulate that. Is it possible that sound from, for instan... | |
| Bi-wire: is it worth it? Nick_sr, I don't know - inductance is inductance in any configuration but there are different and often strange findings. I've heard, for instance, that shorting positive (red) of upper and lower speaker in biwired speaker changes the sound. I hav... | |
| Bi-wire: is it worth it? There is an interaction between speakers by "Back EMF" generated voltage. Bi-wiring separates speakers by inductive reactance of the wires' and amp's output impedance divider. It works for some speakers more than for the others. I think it depends... | |
| Speaker imaging I hate every-time it happens too (hate spider monkeys), but change can be also caused by other factors. It might be not the amount of light in the room but the fact that radio stations are required by law to lower stations power at about 6PM (prop... | |
| transformers/output impedance Output impedance and ability to drive low impedance are two different things. My amplifier has DF=4000 at low frequencies but cannot drive speakers below 3 ohms.I cannot speak of tube amps but in SS amp feedback always reduces output impedance. I ... | |
| transformers/output impedance Bifwynne, some people believe that transformers and capacitors have no place in signal path. Eliminating output transformer is nice but requires some descent output impedance to drive speakers and it is usually achieved by placing a lot of large t... | |
| transformers/output impedance Absolutely right Bifwynne. That's why audio is more of the art than science. We can calculate but have to match and listen. | |
| transformers/output impedance That's right, except for the losses in transformer. This impedance cannot be simply measured with ohmmeter because transformer does not operate at DC but behaves according to ohm laws for the CHANGES in voltage. It is called reflected impedance. T... | |
| transformers/output impedance Transformer is basically an impedance converter. To set proper conversion ratio we need to know speaker's impedance and recommended tube "plate load impedance". If we don't know speaker's impedance we can measure DC resistance and multiply it by a... | |
| Class D and Power Cables Since amplifier's power supply draws current in narrow spikes of high amplitude it might be better to plug it into conditioner that has energy storage and filter (huge capacitor and inductor). My amp is placed on Furman Elite PFi 20 and connected ... | |
| Streaming, Apple TV, Tell me why not. Steve, I don't question your expertise but perhaps something else was wrong. According to test conducted by Stereophile AE is bit perfect. "Some audiophiles have dissed the AirPort Express on the grounds that its digital output is not bit-accurate... | |
| Streaming, Apple TV, Tell me why not. I'm not sure what compression to ALAC has to do with AirPort Express sound quality. Airport doesn't convert to ALAC - it is done in Itunes. Airport receives ALAC data in packets and using its own clock outputs S/Pdif stream. At this point the only... | |
| Streaming, Apple TV, Tell me why not. Apple TV outputs 48kHz while CD rate is 44.1kHz. Translation between two affects the sound. I use AirPort Express at 5GHz - no dropouts. 5GHz is much better for wireless because is not as common as 2.4GHz(Bluetooth, Computer, Microwave, Cordless p... |
