I was reading this thread and saw many people saying that using a powered usb hub greatly enhances the sound of the ODAC.
could you recommend any usb hub powered up to $ 30.00 for use with ODAC?
Whaaaaat? Who was saying that?
No reason why it would.
I used to connect my DACs through a USB Hub (non-powered), it caused a lot of noise.
I may be wrong then ... however thanks for the help :)
Isolating the computer as a power source and substituting a decent low noise power supply, or battery, can improve the ODAC. As not all computers are built equal your results may vary.
Only way I can see the ODAC improving from a powered usb hub is if the usb port you are using on your computer/laptop does not provide sufficient power. I can't hear the difference between my laptop or pc or office pc (powered usb hub). Sorta like the whole cable debate. Your ears hear what you want it to hear imo. Just my two cents.
TBH a well built power supply should be the cornerstone of any pc build.
I agree, but a decent PC power supply makes an awful supply for a DAC. For example in the below image the top trace is a 5v linear regulator supply, the bottom is the power coming out of the USB port on my PC, which happens to have a Corsair AX850 power supply feeding an Asus Sabertooth x79 motherboard. The real problem is the many sources of noise at various frequencies operating inside the computer.
