| Honesty of the Reviewers @millercarbon +1 "the final arbiter of fidelity is the listener" | |
| Nearly all manufacturers do not advertise/exhibit their product measurements? Why? @millercarbon +100 "it can be very useful to measure certain parameters, in order to quantify progress in design changes, especially changes that might be below the threshold of audibility" - manufacturing of components includes key measurements ... | |
| Honesty of the Reviewers "How honest you think the reviewers are?" it depends who pays for review! | |
| Pleasurably better, not measurably better talking about “measurements” without specifying details is pointless. one measurement to shed a light on how good system is integrated would be measuring sound distortions, phase and FR in actual room, at listener point. you will be surprised wit... | |
| When someone tells you it's a $40,000 amp, does it sound better? @jumia +1 "Most class D stuff is all about fitting lots of power in a small package." +at lowest cost | |
| Cartridge recommendations @listener2 zephyr mk3 is “normal” output, MM cart, any good phono pre should work, - enjoy! | |
| When someone tells you it's a $40,000 amp, does it sound better? @atmasphere "But to be fair, lots of tube amps can do this too, through” I wish you (really) good luck matching tube amp with D-class Amp! | |
| When someone tells you it's a $40,000 amp, does it sound better? @atmasphere "Honestly no-one can hear that.” sure, if you give me $100,000 budget for output filter alone, I can design output filter with close to 0 Ohm ESR caps and 0 Ohm ESR inductors etc.. :-) what about reference sampling clock purity, do ... | |
| Audio Science Review = Rebuttal and Further Thoughts @fleschler in your case Ti BB outdated DAC chip could be limiting factor by itself.. also, I don’t see post-DA converter and filter / ref-clk design details, therefore it’s hard to say what affects midrange in your case. | |
| When someone tells you it's a $40,000 amp, does it sound better? @atmasphere 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 t... | |
| When someone tells you it's a $40,000 amp, does it sound better? @larrykell there is a max current limit through the speaker.. I agree, there is advantage of having more output transistors in parallel to extend output stage linear region and to dissipate heat, which reduces distortions at high power end, but u... | |
| When someone tells you it's a $40,000 amp, does it sound better? "if the class D is designed properly the amount of noise it makes on account of its switching can be less than many tube or solid state amplifiers." not really, please try to hookup the oscilloscope to the class-D amp output while driving speaker... | |
| Is Accuphase a good match for my system? @lalitk +1 every brand has line of different components, scaled by power, quality etc. rule number one I follow is matching amp with speakers, at least by power and impedance. "difficult to drive” speakers, typically featured with third/fourth o... | |
| When someone tells you it's a $40,000 amp, does it sound better? @sns +1 HiFi separate components, manufactured in very small quantities, have to be priced very high to cover huge R&D cost, internal parts cost more in lower quantities, tooling setup cost, ppl training, sales and marketing travel, exhibitio... | |
| Audio Science Review = Rebuttal and Further Thoughts @fleschler +1 "it's not so much the DAC chip but the implementation of the entire DAC unit” I prefer DACs with: 1) separate DAC Chip for left and right channel, two or four in parallel for each for better interpolation 2) avoiding OPAMPs in sign... |
