Cayin RU7 | 1-bit dongle DAC for the masses!

▶️ Available for pre-order now!

When the Cayin RU-6 first launched back in late 2021, it was one of the first dongle DACs to feature a full fledged R2-R ladder DAC, made for portable use on the go. The reception was well received with many people praising how amazing the sound quality was considering its miniscule size. Even back when we first auditioned the Cayin RU-6, after some cable swapping we were blown away on how good and high end the sound quality was, even trading blows with  many audiophile DAPs (some costing way more than the Ru-6) at the time.

The following year, Cayin once again made headlines when launching their N7 DAP; the world’s first 1-Bit DAC implemented into a high end portable audio player. 1-bit DACs are neither new nor rare, commonly only found in desktop DACs and CD players, so seeing Cayin integrate this technology into a DAP was new and different. When reviewing the N7, I personally found it to be one of the best DAPs in the price range, both on sound and features, and it seems Cayin took the hint, and decided to combine the 2 to create the same signature as the N7, but with the portable form factor of the RU-6. Enter the Cayin RU-7.

For the uninitiated, RU7's 1-bit decoder converts all PCM files to quad-rate DSD first via DSP logic, while letting native DSD material flow on to the 128 discrete resistors in its DAC – in short, it acts as a simple analog low-pass filter. There is zero error at the point of conversion in a 1-bit DAC, while the pitch for DSD's 1-bit conversion is digital at its simplest and closest point to analog – level represented only either as a 1 or a 0, switching on or off. RU7's discrete proprietary tech immediately differentiates itself from commercial DAC chips, where IC packages are often too small to perform an ideal 1-bit conversion. RU7 also avoids the errors of dynamic element matching inherent to 2-7 bit delta-sigma decoders.

Cayin differentiates RU7 from RU6 on both exterior and interior specs. The Ru-7 external shape is more or less the same, with a less angular design and more distinctive buttons for mode and volume control. Unlike the Ru-6 which features a pure line-out option in which the volume control is bypassed for a fixed voltage out, perfect for listening into car stereo systems as well as handy and portable personal speakers, the Ru-7 now features a shared line-out, but in turn they also now feature a shared output power (using both 4.4mm and 3.5mm simultaneously) The RU7's output power is also doubled compared to RU6's.
