| Is age bad for solid state amps? "Is so complex all this"It really isn't - you'll expire long time before transistors. | |
| Is age bad for solid state amps? Cinequadom - Transistors don't age or deteriorate. The only other component I know (other than tubes) that deteriorate is switch. | |
| Is age bad for solid state amps? Electrolytic caps can last 50 years but every 10degC in temperature increase cuts life by half (it is simply drying out). It is gradual process that increases ESR (Effective Series Resistance) of capacitor up to a point where ESR is so high that c... | |
| When have A/B comparisons led you astray? "i just change stuff. period, and don't worry about it"- So do I. I found that switching A/B is not as good as playing one component for a week with different types of music then do the same with the other. Constant switching between components to... | |
| HeadPhones: Best soundstage? With headphones sound is inside of your head and not in front of you as it is with speakers. It is because when you listen to speakers each ear receives also delayed sound from another speaker (right ear from left speaker). Same can be done in hea... | |
| When have A/B comparisons led you astray? Placebo effect. My brother went to audio store to buy Cabasse speakers. Salesmen presented first speaker that sounded very good. Then he played a little more expensive speaker that sounded much better for a little more and finally even more expens... | |
| How loud is loud, What DB is actually loud? Frank, Thanks, great link. | |
| How loud is loud, What DB is actually loud? "Play your system in mono, turn of one channel , guarantee you will have more than a 3db loss" Yes, but not because of the smaller radiating area but because you cut off half of the power.yes, there is room gain, but since it applies to both speak... | |
| How loud is loud, What DB is actually loud? If you replace one 8ohm speaker with two 16ohm speakers in parallel then area will double but power to each speaker will half and SPL will stay the same.Two 8ohm speakers in parallel will receive total of 2x power resulting in 3dB increase in SPL.... | |
| How essential is shielding? Mapman - who knows? It is a little like ghost chasing. I'm in this business (designing electronics) for a very long time (32 years) finding something strange every single day. | |
| When is digital going to get the soul of music? I'd like to mention that 192kHz applies to incoming signal while DACs have much lower THD distortions around 100kHz. For that reason Benchmark decided to ouput data to DAC at around 110kHz. | |
| How essential is shielding? Hasse, Active shielding means placing buffered common mode signal back on the shield thus reducing capacitance and therefore pickup. It is technique widely used in low level amps like EKG amps but Synergistic's definition is different. They just c... | |
| Success Rolling Opamps in EE Minimax DAC Douglas_schroeder, Audio was ignored for a long time in op-amp design NE5532 being the first designed specifically for the audio. I'd like to try the newest OPA1612 that according to technology progress supposed to be light years ahead but I alrea... | |
| Which purchase tipped you into nirvana. 9.5ft Wow. We have tall ceilings now but I remember times we were living for many years in a hovel with such low ceilings we could only eat pancakes. | |
| Amp damping factor? Bifwynne, It is a trade-off. Amplifiers with very high DF use a lot of negative feedback that enhances bright sounding odd harmonics. How much of DF do you need? It depends on the speaker damping and room acoustics and perhaps many other factors. ... |
