Best way to eliminate "common mode" noise from AC
One possible way would be to add common mode choke. It can be done by making few turns (as many as possible) of the power cord on the large ferrite (chose one with the highest permeability). When wires in the cable carry current in opposite direct... 
Computer output to DAC, which route?
It is difficult to compare USB to Firewire since Firewire is expansion bus while USB is peripheral bus. Firewire speed is guaranted while USB speed is much lower than rated because it runs under protocol. 480Mb/s rated USB 2.0 runs at about half o...

Matt, It is not that AE cannot see your music library, but perhaps program you use to transfer music (like Itunes) cannot see your library. 
What is the best....?
Warm vodka and big sweaty women. Wanna join? 
Need help with Apple Airport Express
Matt, AE is by default set to receive both 2.4GHz and 5GHz. I use Linksys as two separate networks with different names: 5GHz with MacMini and AE, 2.4GHz with other computers. I could set my MacMini to transmit both frequencies but couldn't find h...

Matt, Do you mean Itunes cannot access music library?

You will find in System-Router menu: Setup, Wireless, Security etc.. Select Wireless. It will open Basic Wireless Settings, Wireless Security, Guest Access etc. Select Guest Access. It will show option "Allow Guest Access" Yes/No - select "No".Gue...

It is not discrete time system since discrete time system has countable number of states by definition. The states here are percents of duty cycle (quantity of interest) that changes with infinite number of states in similar fashion to change of f... 
My two cents...
B_Limo, I had both Studio 60 and 20. Studio 20 had annoying frequency hump around 120Hz that is most likely multiple of bass reflex tuning frequency. It is a matter of synergy. Aluminum dome tweeter was very revealing. It became unbearable with op...

Atmasphere, that's true but output power is very limited while in class D it depends only on power supply and size of output Mosfets.Bombaywalla, Adjusted analog quantity is duty cycle. For instance, when you adjust oscillator's frequency by turni... 
Ravi Shankar passes.
Donjr, Sultan Khan died last year. He was Sarangi player and vocalist but I don't have any of his records. Ali Akbar Khan was pronouced by Yehudi Menuhin "An absolute genius...the greatest musician in the world,". Musicians that are the most popul... 
Ravi Shankar passes.
It is Vilayat Khan (you dropped an i and a). The greatest of all was Ali Akbar Khan (Sarod) whose sister Annapurna Devi was married to Ravi Shankar and studied together under her father great Alauddin Khan. Annapurna Devi was perhaps even more tal...

Signal chain might be simpler but class D consist only of modulator and output Mosfets vs. multiple stages of gain in traditional amplifier.

Bombaywalla, Class D amp doesn't convert anything to digital. It converts analog voltage to analog duty cycle of square wave and back to analog voltage thru filtering. Word "digital" would imply limit of resolution while it is unlimited - complete...
