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.

4.5 star
Color: Low Profile Oil Drain Pan for Harley, Color: Low Profile Oil Drain Pan for Harley
Id give it a 4.5 star only because the holes weren't well rounded on the interior were they punch through the mold to make the holes. Other than that I tested if it holds full of water and all seals work. The fix: grab a knife scrap the inside ring and it will fall off. If you want a more perfect feel (not rough) heat up a flat head or screwdriver that has a round stem and use that after heating to lightly melt the plastic to smoothen it out. I didnt do 2nd part dont care. Great size, will fit under motorcycles easily like my 04 zx10r.

1999 BMW 528i Fit and works like Original BMW-Pleasantly Surprised
1999 BMW 528i M52TU Engine. Pleasantly surprised and impressed. Everything fit as it should. Yes, one connector pipe took a bit more pressure to get it to "click" and lock, but it did click and lock..and better tight to insure no vacuum leak. Definitely works well and stopped the vacuum leak that old system had. Would recommend especially since price point might lead one to think that quality is not that good, but I'm glad I didn't spend any more on something else. Highly recommend.
