To expand a bit on what Nhubley said, Monoprice is actually a bit of an anomaly in the industries they cater to. Their bang-for-the-buck ratio is unmatched by far , combined with cheap shipping prices, fast shipping service and excellent customer service. I really have no idea how they do it.
Their stuff is from China, but the product quality is above average or higher, which is odd for China. They must have very tight QC. Also, their shipping prices are so low they may be at cost. For those in Southern California they have an extremely inexpensive Norco Overnite option; it's dirt-cheap. They ship fast, too. They have an Amazon-like shipping time feature ("this item will ship Today if ordered within the next X hours, Y minutes").
Their customer support is stellar and complements the rest of their operations to the fullest degree. If you have any issues, they'll take care of you. I've bought from them for longer than I can remember. Probably since early 2000s. Always a happy customer.
I've been tempted to pick up one of their desktop USB/DAC/Amps. At $98.00 it's hard to ignore it. See it here:
