| What is the “World’s Best Cartridge”? @lewm I have to say I'm amazed that you have had the continuing patience to deal with the 7241 power tubes! We don't modify any of our amplifiers to use that tube since most people don't have the patience to deal with them. | |
| Sansui AU-717 @chocaholic Any technician competent enough to service a Japanese receiver can do the work just fine. Just have him put in Nichicon or similar quality capacitors and you'll be fine. Bonus tip: ask him to use SN63 solder if he does not already. SN... | |
| Sansui AU-717 I generally live by the “if it ain’t broke, don’t fix it” philosophy but suspect that may not apply here. @perkri It may seem to work but I guarantee its suffering and not performing to spec. When the filter capacitors in the power supply fail... | |
| When someone tells you it's a $40,000 amp, does it sound better? Yeah that probably relates to higher cost class D amps. But mostly d amps are bargain basement variety and sound pretty bad. @jumia That is true of some but not all. I have two customers that were quite surprised by the Nobsound class D amps w... | |
| What is your take on high efficient speakers vs. low efficient speakers? We are all basing our opinions and experiences using " reproduced / recorded " music. As I have said many times, this alone, creates many challenges for us as listeners. It boils down to the specifics of what YOU want your favorite performers to ... | |
| At this level of high(er) end audio why not offer balanced connections? Because your assumption that balanced is better is not correct. If you’re saying, they should offer both, that is not without compromise. Simpler signal path is superior. If the balanced connection adheres to AES48 then it is better in every ... | |
| When someone tells you it's a $40,000 amp, does it sound better? Isn't the harsh reality of class D is that it's to clinical and precise, and harsh. With class AB you get distortion and isn't that what harmonics is all about when you listen to music. It's all about the design and the colorations that are done ... | |
| Which preamp to go with pass labs x150.8 @panerai557 Your amplifier has balanced inputs. If you want to get the most out of them, the preamp should support AES48 which is the balanced line standard. To the best of my knowledge, ARC has never made such a preamp despite being balanced. An... | |
| 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. |
