| Should an audio system be left on at all times? Stanwall - Check this link: http://www.dfrsolutions.com/pdfs/Uprating_of_Electrolytic_Capacitors.pdfThey mention temperature as main factor (and 10 deg C rule). ESR while getting lower at high temperatures (might explain reason for warmup) eventua... | |
| Should an audio system be left on at all times? Stanwal - I stated what capacitor companies claim. Going bad when not used, that you mentioned, has place when you not use amp for long time (years) and aluminum oxide layer (serving as isolator) depletes eventually lowering allowable voltage and ... | |
| benchmark and apogee Shadorne:Thanks. It shows as one hot high sibilant - audible at first but much better now (but still there). I will think of notch filter at 9kHz. In spite of that it is still a lot cleaner than $25 Vifa it replaced. I would not do this again - i... | |
| Should an audio system be left on at all times? Knownothing - I think so. Capacitor companies like Nichicon mention only temperature as limiting factor (and not the rush current). | |
| Should an audio system be left on at all times? Pdn: I was talking about SS. As for time - it might vary and I don't know of any rule. I'm pretty sure the same applies to tube gear but have no experience there.Stanwal: It might be better to leave computers on all the time (because of hard disc)... | |
| Should an audio system be left on at all times? System should warm-up in less than 1/2 hour. Keeping system on all the time will:1. Shorten life of your amp since elctrolytic caps life drops by factor of 2 for every 10 deg. Celecius.2. Create unnecessary risk during tunderstorm/voltage spike (y... | |
| benchmark and apogee Frank_sm - My Benchmark was on the bright/brassy side with aluminum dome tweeter. After replacing with soft dome tweeter it is way better. Tweeter (Morel Supreme 110) is a little on the hot side but also much cleaner (underhung motor). | |
| ICE amps need cooling? Muralman1 - I still don't understand why you keep calling switching power supplies "digital". As for them being suitable only for mass market and not for the audio (your original statement) your Henry Ho (H2O) released two amps with Icepower modul... | |
| ICE amps need cooling? Muralman1 - yes it is pretty much the same. I have no idea why you call switching power supplies digital and amplifier analog. Both of them are analog (no discrete values) and both operate with PWM and feedbacks. Modulation process might be differ... | |
| ICE amps need cooling? Muralman - I don't know how many times I have to repeat that - CLASS D IS SWITCHING POWER SUPPLY. Switching itself does not make class D or SMPS digital. Both of them are exactly the same thing.There is very little noise in properly designed SMPS ... | |
| How to fix a lack of bass Null Shadorne - I will gladly switch my room acoustics for tall blonde Swedish girl. Do you have her phone number? | |
| ICE amps need cooling? Muralman1 - I said it's funny because they think power supply should not switch but the amp itself should - and both of them are the same thing.On the other hand I don't think they are THAT stupid and have some purpose in mind. The obvious one is ... | |
| ICE amps need cooling? Muralman1 - I don't recognize this module. It is probably made by B&O for car market and not the home audio. In addition it is in application that always uses switching power supplies - no linear to compare with.Yes you'll find switchers in ev... | |
| ICE amps need cooling? Muralman1 - I don't know what context was that. You stated that digital power supply ICE modules are instituted in mass production of popular electronics - could you provide us with example of popular mass produced electronics with ICE module in i... | |
| How to fix a lack of bass Null Magfan - 3/4 is good enough for me. I have echo problems in my room but I'm not going to hire consultant - way too expensive for me. I will study the problem myself and settle for 3/4 (or even 50% improvement). |
