FiiO K11 R2R DAC and Headphone AmplifierFIIO's newly self developed four channel fully differential 24bit R2R DAC consists of 2x 48 precision thin film resistor arrays per channel, totalling 192 resistors with 0. 1% tolerance and low temperature drift(30ppm). This configuration delivers a unique and charming sound.

FIIO's newly self-developed four-channel fully differential 24bit R2R DAC consists of 2x 48 precision thin-film resistor arrays per channel, totalling 192 resistors with 0.1% tolerance and low temperature drift(30ppm). This configuration delivers a unique and charming sound.

The K11R2R employs a fully differential architecture, resulting in lower noise, with less FFT harmonics and a darker music background compared to typical ones.

The NJW1195A is a 4-channel electronic volume controller. The resistor ladder electronic potentiometer is low distortion and low noise, allowing precise volume adjustment.

3 gain levels+ 3 independent volume curves
The 3 independent gain levels and volume curves allow the K11 R2R to give you a better listening experience with various types of headphones, whether you are using sensitive earphones or harder to drive over-ear headphones.

The capacitors' ultra-low ESR, combined with excellent anti-interference capabilities, allow them to provide a stable and clean power supply and thus achieve high-quality sound.

Eufy 11S Max Replacement Parts Work Well
Size: 20 PACK
For the 11S Max, the parts fit great. Changing out the parts is easy, and the parts are durable. I like that this kit has a new filter for everytime you change out the rotating brushes. Changing out the parts make the eufy vacuum cleaner function better everytime. I can’t tell a difference in the noise level when changing out the parts. Overall, thus is totally worth the money to keep the Eufy running in its best shape.
