Wavelength Audio, ltd. News Page.

Welcome to the new site for Wavelength Audio, ltd. As you all may know I have been really busy designing for other companies and have neglected to keep everyone up to date on what’s going on. Hopefully the new site will allow me to do that.

5/2023 USB Spacelator isolator reclocker with a new ultra low noise regulated 5V VBUS/GND. $500 shipping now. So this little thing has a HOST port, DEVICE port and 2.1mm power intake connector. The HOST USB Signal (FS/HS) is isolated and then rechecked to the DEVICE side which is powered by a low noise supply. I made several prototypes of this and this works the best.

Only 8 more Brick N2s available before we are out of MagneQuest transformers. I do also have 4 pairs of Silver ones available for the Callisto N2. I have 16 more upgrades for Brick of Brick AG to N2 left.

Pelham USB DAC is released. It has a USB/DAC module with isolated 24/96 USB into a new controller powered by dual low jitter oscillators into a new reclocker with differential I2S output into dual hybrid NOS dac chips with passive IV conversion (DN2). That differential output is sent to the main board with dual 1:1 isolation transformers make the differential to single ended conversion and send that directly to the 71A output tube. The 71A tube is loaded with a custom 50% nickel choke and an 80% nickel output autoformer. The Pelham is powered externally by a linear regulated power supply with switchable 120/240 voltages. $9000, Silver autoformer available as well for $19,000 and double silver with silver loading choke $27,500. Silver available in limited quantities.

I had to discontinue the Crimson, no more transformers for that. Instead I am releasing the new Pelham 71A DAC before the end of 2021.

I am reworking the Secant to something a little easier to make.

There are two Cosecant N2 DACS that are new left, then that’s it: $3500 I also unearthed a Cosecant USB HS2/Quotient in my RMAF 2019 boxes that is available $3500.

IWe are shipping the Pro Audio Engineering switching supply that is extremely low noise and works at any voltage from 100-250V 50-60Hz for Brick N2 customers. US customers can ask for this supply as well if you live in an area of shotty AC.


Cosecant has birthday, In August 6th 2003 I finished making the first Cosecant. At that time David Evett did the metal work and I did the rest of the design. I was a little suspicious of how well it would sound. I connected it to a white MacBook with a 80G firewire drive and 3 ripped albums and was so surprised at the results. The rest of course is history.
