SMSL is a previously obscure Chinese manufacturer that sells both here and elsewhere. The SD-650 is only one of a variety of new and very interesting products.

The SD-650 is an amazingly high performing unit for the money, which competes well with the typical competition at twice the price level (many of which are USB only DACs), as well as against very much higher priced units that contain what are considered the best DACs made.

Operation is very simple and the tiny and brief manual is all you need. The built in VESA driver diverts default audio output on a Windows computer automatically to the digital out, allowing you to plug it into any USB port. It allows headphone output to be turned on and off, which is handy, allows for three different kinds of digital inputs, locks on flawlessly, and doubles as a supremely high performing headphone amplifier.

I have two of these as well as much higher priced DACs which can beat it at about ten times the cost- but not by as much as one would think.

The most likely use for the SD-650 is to transform any PC system into a true audiophile stereo, if high quality speakers and amplifier are combined with it. That just isn't possible with the cheesy DACs built into typical PC sound boards. If you've been running out of a PC sound board and switch to this, you will be absolutely amazed.

Most highly recommended!
