Cheap R2R with a big amp attached — loved for its warmth, doubted for its numbers, and dogged by a crackle.

The press called it the best-value Bluetooth DAC going; its owners mostly agree — once they've survived the firmware, the app and the battery.

A desktop amplifier's muscle in a 620-gram brick — reviewers agree on the power, argue about the heat, and owners argue with reviewers about how long it lasts.

The K17's chassis, knobs and streamer for a little over half the price — reviewers call it the value pick of the line; owners say the firmware took a year to catch up.

A palm-sized, USB-powered DAC/amp that reviewers found clean and quiet — and that owners split on for power and staying power.

A sixty-dollar Bluetooth DAC with a battery you can swap — and a battery everyone has an opinion about.

The dongle that behaves like a desktop amp — including the heat, the appetite for power, and a menu with more ambition than its software.

Desktop-class numbers in an 8.5-gram dongle for $33 — and a long argument about heat, the cable, and how long it lasts.

A genuinely powerful portable with a power rating it couldn't live up to — and a bright streak that splits the room.

Reviewers call it the best $59 dongle going; owners' pockets and phones keep finding its weak spots.

The smallest, loudest Bluetooth DAC/amp of its generation — with a radio, a hiss and a volume wheel its owners keep arguing about.

A pocket DSP powerhouse that measures like a desktop DAC — and asks you to learn it before it pays off.
