| 300b lovers And then we get into the deeper waters of the sonics of the regulators themselves. Some are slow and noisy, and intermodulate with the music. Others are fast and silent. Regulators do not all sound the same, and passive CLC supplies can have a si... | |
| What is meant exactly by the description 'more musical'? Till today does not exist a precise measurements that can tell us ( bullet proof. ) why we like what we like and audio item specs alone can’t tell us if that audio item will match our taste till we tasted. This statement was true in the 1960s a... | |
| What is meant exactly by the description 'more musical'? but still have rising distortion vs frequency often starting around 2khz. Is it correct to speculate that these amps, whether GanF, Hypex, purifi, etc. would sound more musical if the distortion increase could be pushed beyond 10 khz rather tha... | |
| What is meant exactly by the description 'more musical'? @mglik You are right but everyone uses the same hearing perceptual rules. Its a sort of common denominator. Over time, as a designer you gain experience knowing how the distortion profile looks as compared to how it sounds. It gets to the point t... | |
| Phono cable (RCA-RCA) from TT to Phono Pre Question @mmcgill829 As far as sound quality goes, I'm sure that cable is just fine. But you might want to look into the loading issue. It can make a difference with a lot of preamps that don't like the RFI I mentioned! Take a look at this link on cartrid... | |
| Phono cable (RCA-RCA) from TT to Phono Pre Question @mmcgill829 You still have the issue of the cable capacitance in parallel with the inductance of the cartridge, but now the inductance is much lower and higher ’Q’ (Quality, which is to say the inductor is wider in diameter than it is long). This ... | |
| Phono cable (RCA-RCA) from TT to Phono Pre Question @mmcgill829 If you have a MM high output cartridge, the inductance of the cartridge and the capacitance of the cable set up an electrical resonance that might be ultrasonic or might be at the high end of the audio band. It might also be as much as... | |
| What is meant exactly by the description 'more musical'? Interesting , some people can hear negative feedback = TIM and simple temporal distortion in addition to the various forms of harmonic distortion Ralph and a FEW ear/brain centric designers ( very rightly but not completely ) focus on. @tomic60... | |
| What is meant exactly by the description 'more musical'? @wyoboy My comment So if you want the amp to be musical, its important that the distortion vs frequency is a flat line across the audio band (or nearly so- 10KHz is probably acceptable since harmonics at 20KHz won't get a lot of attention). Tube... | |
| Clayton Shaw Acoustic Lab's Caladan open-baffle speaker ($3295/pair). Open buffle is very popular now , and i try to understand why? @bache Open baffle speakers have rear firing information. If the wall behind the speaker is at least 5 feet, then the ear can use the resulting time delay as echo location informati... | |
| 300b lovers The bottom end is predictable. ~8K 6sn7 (260v, 9mA) internal impedance and 70-80H transformer primary inductance gives -3db around 20Hz. Actually I measured -2.37dB at 20Hz and -3.62 at 15Hz. @alexberger Here's something to keep in mind. If you... | |
| What is meant exactly by the description 'more musical'? @mahgister You got it. @wyoboy what is your take on hybrid amps that use both tubes and ss at the output stage--do these amps suffer from the same issue as ss amps? or are they better at dealing with the higher-order harmonics b/c of the tube... | |
| My VERY POSITIVE Experience with VTV and Warren Coleman (Attention: Sound Lab Owners!) @bouncehit We don't know when but we are working on it. | |
| 20 year old solid state technology..... or has electronics at this level not evolved that much outside of "subtle refinements"? @phasecorrect In the 1980s there wasn't a single amplifier design made that had sufficient gain bandwidth product to support its feedback across the entir... | |
| My VERY POSITIVE Experience with VTV and Warren Coleman (Attention: Sound Lab Owners!) The Sound Lab loudspeakes are, in my experience, and simply put, THE BEST ESL CURRENTLY IN EXISTENCE. Agreed! |
