| 16 bit vs 24 bit vs 35 bit vs 36 bit vs 64 bit DAC sampling to several who have noted (correctly) that 20 bits is all that can be truly used ( and I'd argue more like 17), but wonder, "why 32, 35, 64, (finger to mouth 1 million)?Before going on i have also seen "but rate" and "but depth" used. Let's be c... | |
| Tube or R-2R DAC for Tube System @charles1dadsI I must be missing your point,since i addressed why one of those options is commonplace and sub optimal, and the other has serious issues. Could you clarify what you are pointing out, or want to know?G | |
| Tube or R-2R DAC for Tube System Learning now! Entirely passive seems like a tough proposition since the output will have a variable impedance and a high one at that. For a home/hobby project where you can control the next stage maybe its feasible - but in commercial proactive ... | |
| USB signal timing goes mainstream. Just an FYI I am not going to argue with you. I sat with MPEG int he 90s and learned a great deal about what we cannot measure well. Mostly i learned that there is much i don't know and it best to begin with empirical data rather than accepted rules.I actual... | |
| Tube or R-2R DAC for Tube System there seems to be some confusion with terminology. Multibit = R2R. They can be discrete resistors soldered onto a PCB or thin or thick film hybrids on a IC; but they are both ladders, and both take in PCM and spit out PAM.Bitstream is a differen... | |
| Aurender music servers: higher priced ones sonically better? The problem is PCs are simply not created with noise reduction and power conditioning in mind.Correct. Which is why i advocate simply isolating it and creating a dedicated low noise power supply on the "clean"side and allowing the Mac streamer to... | |
| USB signal timing goes mainstream. Just an FYI Your basic argument is "you cant hear it". This is quite different from "it makes no difference" and the audibility is debated by many. Including me. I cannot explain it (and noted that above), i understand precisely what you are arguing, but neit... | |
| USB signal timing goes mainstream. Just an FYI i should clarify; i presume you mean DAC as master clock, with the ability to terminate, buffer, & re-clock, whcih is what i do and what i believe meitner does. | |
| USB signal timing goes mainstream. Just an FYI The best USB DACs for music all use asynchronous mode. Eliminates this as an issue. I could go into detail. But do your own homework. EMM does, Wavelength Audio (Gordon Rankin) does.. as do many others.You are correct both in the fact that t... | |
| USB signal timing goes mainstream. Just an FYI Just sayin', none of that technical gibberish ( and I'm a 30+ year EE in both fields) has the slightest thing to do with clock recovery and timing. The fundamentals persist regardless of forma or content - the bits must be recovered, and in digit... | |
| Aurender music servers: higher priced ones sonically better? I did all sorts of software and format changes. I doubt there was much I didn’t try. Bought a bunch of high res files. Tried from the MacBook, USB storage, network storage. All sorts of interconnects. The more I think back the more stuff I real... | |
| USB signal timing goes mainstream. Just an FYI missing the point. Don't worry about USB2 vs 3 vs 4 - its all just speed. As the speed rises timing becomes more critical. Re-clockers have been a debated thing in audio over USB for some time. here's an example of the same approach being used fo... | |
| Tube or R-2R DAC for Tube System generalizations are not true and it really comes down to implementation. Bingo. When they are true its someone using a brute forcet echnology to overcome design limitations. "I cant make it warm and natural so I'll throw in some tubes". Pass, wi... | |
| Tube or R-2R DAC for Tube System Whys is tubes and R2R a choice? Why not both if you happen to think they are to your liking?Orthogonal decisions. Like "V8 or red car?"Anyway i personally think that choosing by technology type is not particularly valid. I can make FETs, BJTs and... | |
| Aurender music servers: higher priced ones sonically better? @ghdprentice, can you say more?I clearly had a different experience, and its unclear what steps you took to get good sound out of a "macbook and/or PC". Further, mac books and PCs are significantly different -- starting with, until very, very rec... |
