| Eliminate USB from the chain? In USB, Firewire, and Ethernet there is no issue of clock jitter since there is no clock related to D/A conversion. Information is sent as a data. The issue is to keep just right amount of it. Too much will overflow receiver’s buffer while too lit... | |
| Eliminate USB from the chain? Both Async USB and Ethernet don't operate in real time (timing doesn't matter). Because of that the only thing that counts is DAC's sensitivity to external electrical noise and amount of this noise injected in each scheme. Ethernet should be a l... | |
| Audioquest King Cobra vs. Yukon? King Cobra is a new name of Python (that had great reviews). To stay competitive AQ moved production to China, reduced prices and renamed cables. Python became King Cobra, Viper - Diamondback etc. I replaced King Cobra with much more expensive... | |
| What does a Hexfred do? rodman99999, Fig. 1 is incorrect. For that to work properly it needs grounded center tap of transformer. There are Schottkys operating at higher voltages. 60V would not be enough for most audio application since each diode in bridge rectifier... | |
| Benchmark AHB2 Amplifier, opinions and competition I've read a lot of reviews before I bought AHB2. Here is summary from "Absolute Sound"Because accuracy allied to absolutely reliable performance is the goal of all the Benchmarks, they are not products that tend to attract cults or other sorts of... | |
| What does a Hexfred do? Amplitude of the spikes produced by rectifier diodes is not as dangerous as the rate of change (dv/dt). Very narrow spikes will couple to any LC circuit causing ringing, even if inductance and capacitance are extremely small. Pretty much everyth... | |
| DSD vs PCM .. Truth or Myth SACD didn’t fail because it was an improvement, it failed because most people don’t give a damn about audio quality and think that Apple crappy ear buds are all they needMahler123Very true, but I believe that greed also helped to kill it. To char... | |
| I Think We Can All Agree... At red light a Beetle stops next to Bentley- Excuse me sir, but do you have phone in your car?- Yes I do- So do I, but what about Fax?- Yes I do- So do I, how about TV?- Yes I have TV- I have TV too. Do you have refrigerator?- As a matter of fact... | |
| Differences between cd transports? As long as data from CD is bit perfect the only thing that affects the sound is jitter. Jitter, having many different forms (correlated, uncorrelated etc.), can produce many sound signatures. D/A converter word clock's time variation (jitter) co... | |
| Differences between cd transports? Some DACs perform better with Toslink than USB/coax/etc., so a blanket statement about which input is best for a specific DAC can’t be made. That's why I said "often". | |
| Differences between cd transports? Toslink often sounds worse than coax, in spite of immunity to external electrical noise or not creating ground loops. It is because optical transmitters are slow. Light is moving fast, of course, but transitions are slow making moment of detecti... | |
| Dac hookup.... Ishkabibil, perhaps you meant server. Streamer delivers music from the outside of your home (internet) and often requires different hardware. | |
| Dac hookup.... I use wireless because my DAC is on the opposite wall from my computer and there is no easy way to run ethernet cable. My wireless receiver operates on 5GHz band since 2.4GHz is polluted and has only 3 non-overlapping channels (1,6,11). I also f... | |
| Why Sinatra??? I remember dialog from futuristic TV series "Orville":- There was a contest, long time ago on planet Earth, called American Idol, to find out who sings the best.- But, why???- These were dark times.Each of mentioned singers is so different and som... | |
| Volume level for slightly overpowered amp Power in watts vs volume knob position is not linear - it is exponential (since human hearing is logarithmic). When you set volume pot at 50% of the peak volume position amp will produce 10% of max power (1/2 of volume = 1/10 of power). Assuming... |
