| Leave solid state amps on? Or turn off everytime? Danyal711: I can give you an example of the measured difference in a mcintosh MC400 - on but with no signal applied it draws around an amp. Driving speakers on big orchestral pieces with peaks reading 400 watts on the front panel meters the draw g... | |
| The focus and air lie What this discussion demonstrates is that there are a lot of ways to appreciate music and what is listened to in music depends on the listener. Resolving every detail will require different system specs than hearing the artists interpretation of a... | |
| Leave solid state amps on? Or turn off everytime? Tvad - In practical terms - it really doesn't matter. You will extend the life by leaving the system on, but, as with most questions that come up on this site - it is likely a meaningless difference. Well designed solid state equipment lasts a lon... | |
| Leave solid state amps on? Or turn off everytime? As to a response from a EE - here it is - When power is first applied to a circuit,or cut off, all sorts of transient events occur that never reoccur as long a the system is on. Very high currents and voltages are present that die out quickly. Eve... | |
| tube amp wattage questions/psb golds Assuming that both measurements are made in the same manner and at a low THD limit, say 0.05%, - then the answer to the last part of your question is "100wpc". The biggest reason why tube amps with less power are acceptable is that the distortion ... | |
| Speaker shock absorbers Halcro - I am well aware of spikes and have used them - that was not my question - your answer is non-responsive to my question and, hence both irrelevant and of without value to me. My question was simply where people who had used the method that... | |
| geniuses help- pre into pre--gonna blow up? The speaker connection idea is not necessarily a bad idea. However, you may want to consider building yourself a mechanical A/B break before make box to switch the speakers from one amp to the other depending on what you want to listen to. That wa... | |
| Speaker shock absorbers newbee - I agree with that statement. It appears that you are in sync with the effect that I was trying to control. It had occurred to me that some of what I was feeling was due to the sound wave without interaction with the floor. I do not necess... | |
| Speaker shock absorbers As to weight of the speakers - they are 90 lbs each. The vibration is not bad - the speaker cabinet does not noticably vibrate. But, at 105 db peaks with my feet on the carpeted wooden floor, sitting 6 feet away, I can feel the base. It seems to m... | |
| The focus and air lie Ndeslions: I agree that the sound of most systems is not the same as a live concert. I would extend that proposition to include all systems. Listening to reproduced music in private is not the same thing as listening to live music in a concert hal... | |
| Good speakers at low volume? Branislav: Yes, I found the 803 to sound better than the 804 at low volumes. I performed the same test at one store twice and once at another store. In each case there was only the time to turn off the amp and swap the speaker cables turn the amp ... | |
| Loud background noise: cables picking up RF? Jea48: After looking through my own copy of ARRL's Radio Frequency Interference: How to Find it and Fix it, (sec. 2-8, 22-11, and 3-18) and looking at the schematic of a couple power amps I tend to agree that it is possible to inject RFI via speak... | |
| Good speakers at low volume? I auditioned the Dali Mk II model 400 a while back and compared it to similiarly priced dynaudio, martin logans, mags, focal, b&w, and every other speaker I could find in a 50 mile radius - the Dali made it to my short list. I just don't like ... | |
| Loud background noise: cables picking up RF? No Jea48 you are incorrect - his speaker wire will not act as an antenna that causes transmitted RF to be heard through his speaker - that makes absolutely no sense - if that were the case he would be hearing RF all the time, with or without his a... | |
| How much power is to much power? As to the magazine article referred to- I beg to differ that the phase angle is all that important - the proper term for what is imporant is the group delay. |
