USB Cleanser
USB Cleanser and Reclocker
USB is a fantastic invention for HiFi Audio, allowing a variety of streaming sources to be used with your HiFi Digital-to-Analog Converter. Unfortunately many of these sources, while super convenient, can be prone to emitting large amounts of Electromagnetic Interference (EMI). This can impact the performance of your DAC, impacting the timing and signal levels in the extremely sensitive D-to-A conversion stages.
The APEX USB Cleanser takes the input USB from your streaming source and passes it through three stages of filtering and isolation, electrically isolating the USB input using magnetic isolation, filtering the USB signal itself, then reclocking using an ultra-low-noise power supply to provide a completely clean and re-timed near-perfect USB signal to your DAC.

Clock-Locked USB to SPDIF
USB to SPDIF convertor with Clock Lock
We’ve taken the knowledge used to build the Pink Triangle DaCapo USB input card and created a new board that can be used with virtually any streamer and DAC.
It includes low-jitter oscillators internally so will out-perform most USB-to-SPDIF convertors, but it really comes to life when you use of the Clock-Lock feature that appears in a number of high-end DACs.
Compatible with DPA, Pink Triangle, Cambridge Audio DACMagic, Weiss, dCS Rossini APEX and many other clock-lockable DACs.
Also compatible with external clock sources to sync your DAC and source to the master clock.
CD Player USB Input
Add a USB Input to your CD Player
Lots of CD Players have digital outputs, but a vanishingly small number have digital inputs. This means if you want to use streaming services, you need to buy a completely new DAC or streamer leaving your valuable CD player, and its carefully constructed DAC, sitting idle!
We’ve built a configurable USB input card that can be used to add USB input to many CD players including those from Arcam, Naim and others. Shown here fitted to an Arcam CD23.

Upgrade the clock on your DPA DAC
DPA DAC are great designs, especially when coupled with a Deltran capable transport to make use of their two-fibre clock locking capability. Unfortunately they are slightly let down by the poor quality crystals used internally. These introduce timing jitter which is particularly damaging in single-bit “bitstream” DACs like these.
With this mod, you can replace the factory fitted crystal with a low jitter device, with its own onboard ultra low noise power regulator, to transform the sound of your DAC. Tested with the DPA Bigger Bit, and the PDM1 shown above, this will significantly improve most vintage DPA DACs.
Please note, this upgrade will only improve your sound quality if you have a Deltran capable source. Don’t have one? Take a look at our USB to SPDIF interface in our other listings – these work perfectly to introduce a high-quality USB interface to your DPA DAC.
The description does not lie! The Apex PSU is a very significant upgrade indeed. It retains all the sweetness and beauty of the standard DaCapo DAC but takes it to a whole new level of resolution, focus, and poise. Highly recommended. Alan turned around the job incredibly quickly with regular detailed photo updates on the work. This is a great value purchase for your DaCapo. Don’t hesitate, especially if your unit still needs re-capping. Thanks Alan!

I’ve managed to put in a few hours listening this evening. The USB card has made a massive difference over the Halide Bridge and that is the best USB-SPDIF converter I’ve heard. Total focus, completely tangible sound across the whole frequency spectrum. Together with the external PSU it’s simply mesmerising. I am extremely happy!
