Amazing little board!

Speaking to Brent about Clocking it's incredibly interesting to find out the story behind this little bit of kit .

His excellent signature X5 low jitter clocks have a regulator to help them but this assists in the process to further regulate voltage and ripple to lower the noise floor

I had one regulator for two C5 low jitter clocks

I decided to add another so each is controlled by there own regulator.

Picture wise it's difficult to describe as the C5 made such a difference to SDR and Dolby vision playback

Sound wise clarity is crystal, I compared my x800 back to back same scenes and music tracks and while the Sony sound processing is amazing the speaker set up I'm running seems to struggle with multiple sound items at once

Switching to the Reavon using the combo of the clock and regulator the sound from the speakers becomes better at separating the sound channels and less treble orientated at higher volumes in busy scenes .

Something I've noticed with B&W products is at higher output they cut bass in favour of mid to high.

Now the sound is more even across the levels at higher volumes while voice has a little more bass under tone giving a warmer sound to vocals.

Definitely worth adding to the low jitter clocks to get the most from them.

Dynamic Duo

The combined effect of the C5 and X1 gives a real dynamic clarity, with all aspects of music appearing in front of you.

The sound stage increases and detail deeper in the mix is brought out. Bass extension is there in a realistic balanced way. Overall, a real satisfying live insight into the recording.

A superb combination upgrade

Many thanks

X1 and C5 in a modded Panasonic 9000

I have been meaning to write this review for some time. The C5 and X1 have now been in for 2 months or so. It was a relatively time consuming job and Brent was very helpful as he needed to adjust the C5 output for the Panasonic as it unusually has a lower signal voltage. So a bespoke X1 and C5 were sent. At the same time as fitting the clocks, I did upgrade the LPS capacitors on the analogue side to Mundorf and Jensen with a 1% bypass electrolytic. So its hard for me to be 100% objective with where the benefits came from. However these two mods have taken the player to a different level. It's now performing at a level that is way beyond my expectations. Incredible dynamics, weight and exceptional timing (Or that musicality that we all crave). I compared this player to a high end Audio Note DAC, driven by the internal transport so a fair comparison. This multichannel DAC was actually better in a number of areas (the bass had more weight and slam and bass was better differentiated) the AN was sweeter and had more harmonic tonality, slightly better upper mid clarity, but also less actual overall resolution. It was a close call which was better. In the end I was very happy with a close 2nd from the group of audiophiles who listened. In fact the owner had listened to many DACs over the years and was amazed how good it was. Okay list of what I believe the clocks are responsible for 1. Much less 'digital' hash and a much improved sense of blackness and more analogue 2. Improved dynamics and scale 3. A greater musical insight, a much greater sense of things happening in front of you 4. Increased resolution and clarity (More like listening to a better recording, with a greater ability to listen deeper into the performance) 5. A greater sense of ease, flow and scale In respect of the picture, this also showed improvements, with a more analogue look to the projector, better motion, more stability and a little more image depth. So a very worthwhile improvement to the picture as well. I already have a C5 and two C4's in my Lumagen and this now made me order two X1's for the Lumagen so I can take the image as far as I can before spending silly money on a new PJ !

Another stand out upgrade making a HUGE difference

Adding the X1 clock regulator to a Fidelity Audio C4 mk.1 clock makes an amazing difference.

The noise that I didn’t think was there, with an upgraded mains infrastructure drops away, pushing the music forward with increased detail and further defined sound stage, in an assertive style dropping you into the epicenter of the recording.”

Thank you.

Astonishing Device

"I have got Brent's C4 & C5 clocks installed. However adding the X1 Reference clock Regulator to the mix pushes things to a new level squeezing everything out these brilliant clocks. The C4 becomes the C5 and the C5 becomes the C6. This takes the sound to a whole new level. Fidelity Audio is on to a winner with this astonishing product. I have to add the customer service Brent gives is first class. He really go's the extra mile for his customer's outstanding service."
