I joined HF to learn about a headphone amp for my home system. I was surprised to see so much space devoted to phone related devices. Never realized that there are audiophile options for phones. I'm new to all this, so I hope you'll bear with me if this seems like a dumb question.
I have a Samsung Galaxy S3 with several hundred songs on an sd card. I was about to pull the trigger on a thumb drive sized usb dac when it occurred to me- how can it really improve the sound of my S3? Will I have to reload my sd card with higher resolution files, which will leave me with a fraction of my S3 library?
