| When someone tells you it's a $40,000 amp, does it sound better? what about reference sampling clock purity, do we need $20k World clock device for sampling analog input signal to match class-D amp with the rest of audiophile setup? @westcoastaudiophile If you mean the 'clock' for the encoding scheme of th... | |
| When someone tells you it's a $40,000 amp, does it sound better? I’ve seen any king of while spectrum noise in different D class amps.. never sine wave! higher freq. though! higher switching freq. amps theoretically should be easier to filter noise out, but again, switching frequency generator has the same ref... | |
| When someone tells you it's a $40,000 amp, does it sound better? not really, please try to hookup the oscilloscope to the class-D amp output while driving speakers at moderate power, and check residual noise.. @westcoastaudiophile Are you referring to the 'residual', a sine wave that occurs at the switchin... | |
| When someone tells you it's a $40,000 amp, does it sound better? How can this be when the turning on and off of output transistors at a rapid rate in Class D amplifiers produces high frequency noise which must be filtered out? There is no such thing as instantaneous switching. I tried a Class D amplifier the ... | |
| Peachtree GaN 1 Beta @atulmajithia Its not a simple as you are asking- your question suggests to me that the amps you've heard that use feedback didn't use enough (which describes most amps made). Imagine a bell curve with the bell being the amount of harm caused by f... | |
| Grounding Question can you elaborate on your last statement bout two pronged older equipment? I have an amp when you turn it on you get a ground loop hum hd it goes away when the preamp fully turns on. @dinov That doesn't sound like a ground loop at all. Norma... | |
| When someone tells you it's a $40,000 amp, does it sound better? There can be no crossover distortion because the transistors never turn off. @larrykell It might interest you to know that most class D amps are inherently incapable of crossover distortion. | |
| Grounding Question @chayro Lifting the AC ground is a thing that people do to eliminate ground loop buzz. Its an indication that the grounding scheme of one or more components in the system isn't well thought out. You can test for this sort of thing using a Digital... | |
| Bedini Amp repair Any shop with a technician competent with 1970s-1980s solid state should be able to service this amplifier. If probably does need new filter caps but I doubt that is why one channel 'went fuzzy'. The biggest issue working on these IME is getting ... | |
| Replacement for Carver Crimson 275 to drive Maggi .7’s are you implying that the Carver Crimson 275 only puts out 15 watts in real applications? If so please explain. The amp weighs 19 pounds. It would be something of an output transformer miracle if the amp were to actually make the power claimed ... | |
| When someone tells you it's a $40,000 amp, does it sound better? On the other hand, with an easier speaker load sans passive cross-overs, not least with speakers more efficient, you have a much better outset with less power needed to accommodate topologically more simple and cheaper amps, while maintaining the... | |
| Tube preamp options I am not sure that is 100% a certainly… The cartridge can feed out as balanced or wired to be single ended. I am pretty sure that it is possible to bring in the RCA into a balanced preamp with a custom made cable. (I have done it.) Sonically it ... | |
| Tube Amp for Devore O/96 I have some research to do I suppose as I don’t know Class A from Class AB or what a pentode is. Triodes get their name from having three elements- cathode, grid and plate. Pentodes have two more grids as a method of increasing efficiency, but ... | |
| Atma-Sphere Class D… Amazing I see Bob hasn’t responded. Do you have a couple photos of your class d amp with the black faceplate that you can post…or link to? No- there's not that many built with black so far and none in house. It didn't occur to get some shots of the bla... | |
| Tube Amp for Devore O/96 Ralph I’m surprised you didn’t explicitly support my mention of your S-30. I know the 0/96 may dip slightly below 8ohms in a few frequencies, but might you have any opinion on how the S-30 might perform with the O/96? @blisshifi I appreciate th... |
