| Does anyone care to ask an amplifier designer a technical question? My door is open. @krelldreams I do have technical questions regarding cabling and AC outlet use though! I’m not excited about super expensive cables (I’ve tried many with very little in the way of difference), but there are electrical differences (capacitance,... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bdp24 The old Polk Audio Cobra cables were a very high capacitance design, and caused some amps to become unstable. We briefly sold those cables till we found out if you step on them they short out. Weaving magnet wire into a snake skin is a real... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @twoleftears Technical question: Do certain electronic components, e.g. capacitors, need to "form" before they operate at their best? Electrolytic caps do need to form and the form time is related to how long they have been off or stored. This ... | |
| RMS Power? @kijanki I often see power specifications like "100W RMS". There is no such thing as RMS power. Of course, you can calculate RMS value from any curve, including power curve, but it won't represent anything. "Real" power representing heat diss... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker @kijanki I agree, but amp that doubles power exactly has to have adequate power supply AND deep negative feedback. Exact doubling implies perfect regulation (ideal voltage source), that is not possible without deep feedback. What part do you a... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @ieales More than once I've rejuvenated a system by re-plugging ALL connectors, both internal and external.YES, YES, YES. Ive fixed so many things just doing that. Flat screen TVs, my Sony ES player many times, Its used up 6 of its 9 lives. Its... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @grannyring I have a technical question regarding a PP EL86 tube amp I am modifying. I would like to upgrade the power supply. The current power supply is very, very simple and while simplicity is good I think a more robust supply could help sou... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @prof And if burn in occurs in cabling, why don’t we see people producing these measurable results between a new and burned in cable? The suspicious thing is that when most cable manufacturers are hyping either the technical reasons why their ca... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker I had mentioned in my review that the AHB2 is not able to drive the Kingsound King III electrostatic to an unlimited level of listening. However, there is no degradation of sound as the amp is pushed to its limit, and there is no degradation ass... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker @kijanki Ramtubes, AHB2 has load/line regulated SMPS, but as you mentioned, there are losses everywhere. Exact doubling of power for half of the load means perfect regulation - an ideal voltage source, that is only possible with very deep negat... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @krelldreams My verdict, with this passive unit, in my system is as follows: The system with the passive has clear high and mid frequencies, good space, and sounds spacious... but it is a bit brighter, a bit leaner, and is less pleasant to listen ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bdp24@ramtubes, Here's a question for you Roger regarding a matter that was being discussed amongst Maggie owners on The Planar Speaker Asylum forum yesterday. One poster said of hearing from tube amps something I too hear, and that is of a sou... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @apogee141516 apogee141516176 posts12-07-2018 5:25amThis is kind of an obtuse question, but why do some amplifier manufactures say to use a preamp between their amplifiers and the streamer when you are only using a streamer and power amp, no vi... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @ieales minimize artifacts occurring from the interconnect cable between the preamp and amp.A second reason is that a preamp can provide a fairly high impedance load for the sourceSource output 22R, amp inputs 23k5 or 100K. Adding a preamp with ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @stargazer3 OP do you believe in the burn in process of an amp that over time the sound will settle and finally focus on a cohesive musical experience or is it to your opinion all in our brain that is adjusting to the sound of the component? W... |
