What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Our take on the brand
Polk’s been a major player in the audio world since the ’70s, though they don’t always get the same attention from hi-fi reviewers as some other brands. But they know their niche—mass-market, entry-level products that perform way better than you’d expect for the price. Their R200 model, for example, gets called one of the best under $1,000. If you’re looking for solid performance without spending a fortune, Polk’s stuff is hard to beat.

ORA

Released
2023
Creator. Gamer. Musician. ORA bridges the gap between computer speakers and studio monitors giving you studio-grade, audiophile-approved sound without dominating your space. ORA has modern inputs like USB-C to get the best sound from your PC or Mac, Bluetooth 5.0 to pair with your phone or smart home device, and RCA for your analog gear. Sporting a crossover that automatically sends bass to a connected subwoofer, you get flawless low-end integration freeing up the 3” woofers and ¾” silk dome tweeters to focus on what they do best. ORA is the perfect blend of reference-quality sound and modern features at a compact size to fit on your desktop.
Kanto Audio stands out in the hifi speaker market with its vibrant color options and unique bamboo finishes, departing from the typical black and grey designs seen across the industry. Their speakers, like the YU series, are known for excellent stereo imaging and surprisingly full sound from compact sizes, while the REN model is the first to include HDMI ARC for TV audio, effectively competing with soundbars.
Expand Details
Our Summary
Product Strengths
- Impressive sound quality with balanced and detailed audio, creating a wider soundstage than expected for their size
- Compact size is ideal for smaller desks
- Can be paired with a subwoofer for deeper bass
- Clean and understated design blends well into desktop environments
- Can work well with CRT televisions due to magnetic shielding, preventing buzzing
- Versatile connectivity options including USB-C, Bluetooth 5.0, and RCA inputs

- The ORA sound better than the M1 MacBook Pro speakers, with better bass performance and a stronger midrange
- The ORA sound better overall, cleaner, and more detailed than the Kanto YU2 and YU4, similar to—but possibly cleaner than—the YU6
- The Kanto TUK is in a different sound class, with more depth and clarity, so the ORA wouldn't be considered an upgrade
- The Kanto Aura sounds more distinct and textured than the Audioengine speakers
- The ORA has more prominent bass than the Audioengine A2 Plus
Takeaway: The Kanto ORA speakers offer a great balance of sound quality, size, and connectivity, making them a good upgrade for a desk. They are worth it if you want great sound in a compact design.
