| Difference in sound between copper and silver digital cables? "Difference in sound between copper and silver digital cables?” copper cable with air only dielectric will perform better than any silver + lossy + high-Er/TanD dielectric cable! | |
| SUT Interconnects "By using a meter which measures capacitance” yeah.. capacitance changes vs frequency, that’s why I measure capacitance / inductance / loss / resistance at 50/1000/10000/20000Hz points. | |
| Has anyone switched from Class AB/A to Class D? Was it better? Was it worse? @atmasphere "Actually there are a few class D amps that have a better first Watt than a good number of class A amps.” - list of “few” and “good” ones will be helpful! Analog output filter question: how output filter is designed, order, phase v f... | |
| Has anyone switched from Class AB/A to Class D? Was it better? Was it worse? @niodari you may read about class D design here: https://people.engr.tamu.edu/s-sanchez/ECEN%20607%20Class%20D%202011.pdf | |
| Has anyone switched from Class AB/A to Class D? Was it better? Was it worse? @niodari "You can certainly have a class D amplifier which is better than many class A ones” - better in what sense, max power perhaps? You may dial 500mW output @ 1kHz sine on any D class and A class amp and compare waveforms to understand D clas... | |
| SUT Interconnects MC to SUT connection is a “low impedance: high current, low voltage” one, while SUT to Phono-amp is a “high impedance: low current, high voltage” variant of it. SUT to Phono-amp connection is very sensitive to RFI and other outside noise, thus sho... | |
| Has anyone switched from Class AB/A to Class D? Was it better? Was it worse? @atmasphere +1 "If you know what you are doing you can build a class D amp that is in the driver’s seat rather than the back seat WRT any other kind of amplifier technology." its applicable to everything! | |
| Cable Quest @faustuss I calculated total conductor gauge, which is 5awg for whole cable.. per leg you are correct w/ 8awg number, -thx! | |
| Help! Pre amp turning on by itself. "Help! Pre amp turning on by itself.” - any response from manufacturer? who is it? | |
| Cable Quest SC: the best sounding I found one is KimberKable 12TC, which is about 5AWG.. measured very low loop inductance and resistance, ultra high resolution sound w/ Accuphase pre/amp and B&W speakers. | |
| Cable Quest @stringreen “...they also sound different depending on what they're attached to.” +1 - cables are not dominant factor, unless bad/faulty ones replaced with good ones. | |
| Has anyone switched from Class AB/A to Class D? Was it better? Was it worse? @dman777 I used class D amps for 80kW front end PA gig setup, and I am using AB/A class amps for home sys.. class D has too much harmonics at low output level, RF noise, “weird” pulse response.. | |
| How much do I need to spend to make vinyl sound better than digital? teac phono PE505 is much better than many expensive, often just for shiny optics reason in many ways: https://teac.jp/int/product/pe-505/spec | |
| Analysis Plus Oval 9 Black vs Black Mesh “..who do we believe here?” how about nobody? | |
| Matching a amplifier to speakers Four output KTs are driven pretty hard to produce 180W of power, thus lifespan will not be great, likely below 2000h. |
