| 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... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bdp24 I also remember The RM-5 and the Audible Illusions Modulus 2 were considered THE bargain tube pre-amps to choose between. I found the AI Mod's 30dB of line stage gain unfortunate and ill-advised, as well as it's dual-mono volume controls.... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @almarg That’s interesting to hear, Roger. Although to be precise I’m pretty certain that the 8 and 8B were both single-chassis stereo amps.I’ve never heard an 8 or 8B but during the 1990s I owned a pair of Model 9 monoblocks and a pair of Model... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @bdp24 I have for years heard accusations from audiophiles about TAS and now Stereophile requiring advertising from any company wanting one of their products reviewed. I have never seen any proof of that, and have to point of that though I have ... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @krelldreams You mentioned, that in the RM 9, two KT120 or KT150 output tubes could be substituted for four EL34s in each channel. Is there an advantage to using fewer higher output tubes as opposed to using double the number of lower output po... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. @fsonicsmith not all things that matter are amenable to testing. Indeed we cant test for everything. However we can test for the big three and include that information in our listening. For instance if one amplifier produces a lot more bass f... | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. Hi to all. Perhaps I was not clear in my original posting that this is a thread to ask the OP a question and have it answered by the OP. It was not an open invitation for other designers to answer questions or give their opinions on my answers. Th... |
