| Ferrofluid tweeter My Hyperion HPS-938 speakers use ferrofluid for 6.5" midrange driver suspension (no spiderweb) and most likely in 1" short horn dome tweeter. They are at least 5 years old but I cannot hear any sound deterioration (I think). Hyperion Sound doesn’t... | |
| Darn Chromebook not playing well with Parasound ZDAC It could be software setting, but many people have problems with Amazon Music. Try to update program and the system. You also have Google Play Music available on Chromebook. Does it work? | |
| Dumb question #643: should speaker cables last a lifetime? Copper oxide slows down further oxidation. | |
| Class D Technology Ok, let me clarify then: I cannot hear 500kHz, not only because of my hearing apparatus (at my age I have difficulty hearing 15kHz), but also because tweeter’s output drops like a rock with combined effect of membrane inertia and increasing tweete... | |
| Dumb question #643: should speaker cables last a lifetime? Let's look from technical viewpoint. Small amount of DC voltage on the amp's output, always present, causes drift of electrons called "drift velocity". After a while all high quality electrons, that you paid for, will be replaced by plain ordin... | |
| High Current Outlet for Amps? Krell recommends minimum 20A circuit. They specify 75W at standby, 350W at idle (whatever it means) and 3000W at max. Pure class A amp would draw max power all the time, equivalent to 25A on 120VAC supply.Outlets in my home are 15A style but al... | |
| High Current Outlet for Amps? My power amp is plugged into high current outputs of Furman Elite 20PFi conditioner that is able to deliver 55 amperes peak current. They call it Power Factor Correction. It is achieved by huge inductor followed by big capacitor that stores en... | |

| High Current Outlet for Amps? It depends on the class of amplifier, as randy-11 stated. With typical class AB amp music power is very low, being only a few percent of peak power (unless you listen to sine waves). It is because average 50% of loudness is only 10% of peak pow... | |
| best network switch configuration for audio +1 erik_squiresThere are high quality SMPS but unfortunately the most of them, especially wall warts, produce a lot of switching noise. It is practically impossible to avoid them (light dimmers etc.) but noise can be filtered out. I use Furman E... | |
| Class D Technology I am not sure where obsession with the switching frequency comes from. It is inaudible while the only other thing that it might cause is filtering network phase shift - that can be beneficial since speaker has much larger positive phase shift at ... | |
| Class D Technology No, learning about class D is not your goal. You placed many negative posts on class D with no single positive one. That is trolling. | |
| Class D Technology In learning about Class D, it appears that after the linear signal is destroyed and turned into a saw tooth wave form, the output filter? tries to put the signal back together...doing an incredible job considering the complexity of this task...but... | |
| best network switch configuration for audio Yes, it is 1's and 0's but they have to be converted at exact time intervals to avoid additional "products" that result in overall noise. In your case Ethernet network transfers data and not music. Music is created when timing (clock) for this d... | |
| Your opinions on how to string 25 ft speaker cables 12 gauge wire has about 340nH/ft inductance. It is 17uH for 2x25ft wire and represents impedance of 2.14 ohm at 20kHz. Bringing wires closer reduces inductance, twisting reduces it further.As for high levels - levels for bass peaks will be in ten... |
