Unbelievable Price for an R2R DAC
The Foo K11 R2 DAC is a game-changer in the world of affordable audiophile equipment. Its price point of $160 (or even $130 refurbished) is incredibly low for a true R2R DAC. This undercuts the competition significantly, often requiring at least $1000 to enter the R2R market.
Historically, high-quality R2R DACs from brands like Denafrips, Holo Audio, and others have been prohibitively expensive. The Foo K11 R2 breaks this barrier, offering a serious alternative to far more expensive models.
Sound Quality: Bass, Mid-Range, and Treble Performance
The Foo K11 R2's bass performance is exceptional for its price. It's textured, deep, and extends very low, rivaling far more expensive DACs. This is a significant achievement in a budget desktop DAC.
The mid-range is equally impressive, offering a full, rich sound with a remarkably quiet background. Vocals are clear and well-defined, sitting beautifully within the mix. This level of performance is unusual at this price point.
While not overly analytical, the treble is smooth and detailed without being harsh or fatiguing. It possesses a relaxed, easy-going sound ideal for extended listening sessions.
Soundstage and Imaging: A Surprising Spatial Presentation
The Foo K11 R2's soundstage is surprisingly wide and deep, defying expectations for a desktop DAC. It creates a holographic presentation with excellent instrument separation and imaging.
The precision of the imaging is noteworthy, maintaining its accuracy despite the expansive soundstage. This is a rare feature found in much more expensive DACs.
Overall, the spatial presentation of this DAC rivals some higher-end models, surpassing many in its price range and even some costing significantly more.
Compromises and Limitations
While the Foo K11 R2 offers exceptional sound for its price, it does have some compromises. The headphone output, limited to 300mW at 32 ohms, might not suffice for power-hungry headphones. It also produced slightly grainy sound quality with higher-impedance headphones.
The limited input/output options (RCA, coaxial, optical, USB-C) and lack of fancy features (no XLR, I2S) are also noticeable limitations compared to higher-end units. The included switching power supply, while understandable given the size and price, may also impact audio quality.
Who is the Foo K11 R2 For?
This DAC is ideal for several user groups: those seeking a second stereo DAC, budget-conscious audiophiles, and people wanting a taste of R2R sound without a hefty investment. It’s also a versatile option for use with desktop setups, laptops, and even as a portable solution.
Gifting the Foo K11 R2 to someone starting their Hi-Fi journey could be an excellent way to introduce them to the world of high-quality audio. Its compact size, ease of use, and attractive design make it an appealing and unique gift.
Overall, the Foo K11 R2 offers a compelling combination of performance and affordability, making it a strong contender in its price bracket for anyone looking for a musical and engaging listening experience.
Conclusion: A Stellar Value Proposition
The Foo K11 R2 is a remarkable achievement. It delivers a surprisingly rich and enjoyable sound for its minuscule price. While it has compromises in terms of headphone power and input/output options, these are more than compensated for by its exceptional sonic performance and build quality.
This DAC presents an incredible value proposition. Anyone seeking an entry-level R2R DAC or a budget-friendly second system will find it hard to resist. For those wanting a taste of high-end audiophile DAC performance, without bankrupting themselves, the Foo K11 R2 provides an unexpectedly amazing experience.
