- The listing claims PCM support up to 192 kHz, DOP64 and MQA decoding.
- Includes Type-C-to-Type-C and USB-A-to-Type-C cables according to the listed contents.
- Manufacturer guidance says to connect it to a downstream device before connecting that device to active speakers.

## Pros

- Optical and coaxial outputs offer two digital connection options, with simultaneous output claimed by the listing.
- The two supplied USB cable types cover Type-C and USB-A host connections.
- Customer feedback describes the unit as compact and easy to use, with some customers appreciating its sound and connectivity.

## Before you buy

- The listing calls the product a digital-to-analog converter, but its described connections are USB input and optical/coaxial digital outputs. It also inconsistently gives its weight as 0.1 Kilograms in specifications and 0.75g in feature text, and customer feedback about signal quality is mixed. Confirm the exact weight and desired signal path before purchase. The listed PCM rate wording is reproduced as supplied and does not clarify bit depth.

## In the box

## A good fit for

- Listeners who need USB audio from a computer, phone, player or streamer routed to an optical or coaxial input on a downstream audio component.
- Buyers seeking a compact digital interface with both USB-C and USB-A cable options in the stated contents.

## Less suited to

- Anyone needing a DAC with analogue RCA or headphone output, or a converter that connects directly to active speakers.
- Buyers who need IIS output, which the listing says the PO100 does not support.

## Customer feedback

Customer feedback highlights ease of use, compact size, sound quality and connectivity, including reports of simultaneous optical and coaxial use. Some feedback describes signal quality as mixed. These are customer impressions, not verification of the listing’s PCM, DSD or MQA claims. For buyers routing USB audio to a downstream DAC, the reported ease and compactness may matter, while the mixed signal-quality feedback is a reason to consider the intended setup carefully.
- Positive themes: Customers describe it as easy to use and compact.
- Positive themes: Customer feedback includes positive impressions of sound quality and connectivity.
- Mixed feedback: Signal quality receives mixed customer feedback.
