| 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| Audio Science Review = Rebuttal and Further Thoughts @fleschler in your case Ti BB outdated DAC chip could be limiting factor by itself..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... | |
| Is Accuphase a good match for my system? @ghdprentice + 1 “maybe Accuphase, Audio Research, and Pass” | |
| Gustard R26 @bill_k found more info about esoteric xd series dac - yummy! “[Capable of] 64-bit resolution and overwhelming performance. However, the true essence of this DAC cannot be discussed merely in terms of its specifications. The fundamental goal in ... | |
| Audio Science Review = Rebuttal and Further Thoughts @djones51 latest AKM AK4499EQ chip (2x in my DAC) cost is in-between $100-$200, depending on purchase quantity. | |
| Gustard R26 @bill_k noted, thanks for details! | |
| Is Accuphase a good match for my system? My current sweet system: Accuphase C2450 (w/ AD2850 phono) pre + Accuphase-XLR brown cable + A48 amp, driving 6Ohms 89db/m speakers.XLR cable from pre to amp (accuphase high grade). I use Esoteric k03xd cd spinner time to time. I also have second ... | |
| Gustard R26 @sgreg1 thanks for taking risk and sharing your experience! I am surprised to hear as Gustard design engineers were able to produce decent R2R DAC product! Creating R2R DAC, assuming 20years product life time and other variables, is very hard! ... | |
| When someone tells you it's a $40,000 amp, does it sound better? "How many people have actually experienced listening to a $40,000 amplifier” I am listening music, not the amp. Amp is just a one piece of sound setup I have selected for my home. my current amp cost $10k and it is driving pair of $4k speakers.... |
