Wavelength Audio Cosecant USB DAC (ESS Sabre 32bit DAC Module) with HS2 Quotient Upgrade [2016]) WITH Cardas Clear 0.5m High Speed USB Cable, iFi Audio DC iPurifier, and iFi Audio USB iPurifier2 - $1,750 Each Plus Shipping

***Scroll down to read full details/description below!!!***



This is/was the latest/last version of the Wavelength Audio Cosecant DAC which we used as our main demo USB Dac for many years. It was bought new in v3 Denominator form in 210 (ESS Sabre DAC - $4,000 retail) and then upgraded in 2016 with the HS2 Quotient upgrade (a $750 upgrade at the time). My best results with this DAC where usually streaming native  data i.e. CD, 24/96, 24/192, or DSD 128. This is a DAC that has very good clarity and wonderful tone and sound-staging.

The HS2 Quotient PCMand DSD 32/385 DAC Module Upgrade: 

"Based on the 32Bit ESS Sabre DAC Chip and an FPGA Based DoP section the Quotient Q1 design allows the Crimson (soon to be available for the Cosecant) decode both PCM and DSD to their highest quality. The Sabre32 is used in what is called "Synchronous" mode in that the Master Clock and the Sampling rate are Synchronous. We use discrete power supplies for all the analog supplies and the Master Clocks. The FPGA automatically sets the ESS Sabre DAC chip into either DSD mode or PCM mode. The new analog section features a quad matched transistor output stage. In the Crimson this differential output is tied to transformers for single ended output to the tube stage. In the Cosecant this stage goes directly to the tube output stage. The Quotient module can be plugged into the Crimson or Cosecant and get DSD/PCM performance."

The Unit is in excellent condition with original factory box, documentation, and comes packaged with several sweet items that help tweak the performance of the Cosecant:
  • A 0.5m Cardas High Speed Serial data USB Cable ($400 retail)
  • iFi Audio DC iPruifier ($99 retail)
  • iFi Audio iPurifier2 USB dejitter/filter Device ($109 retail)
  • Two tested good ECC86 Tubes (one Philips and one Valvo [German])
Total value for the DAC, its Quotient HS2 upgrade, and the USB cable & iFi items is over $5K. Yours for $1,750 plus shipping. NOTE: While this DAC may look like older Cosecant's (early v1 and v2 models) which have sold for less, internally the upgrades this DAC has make it a much more current product/tech.

Questions for the seller
Which revision is this exactly? It’s not entirely clear to me. It looks like the latest is the 2018 Cosecant HS3x. Thanks.
The picture that shows the bottom of the DAC clearly shows the version of the DAC and when it was updated (2016). It started off life as a V3 Denominator and was upgraded 2016 with HS2 Quotient (as the sticker Gordon put there shows). To the best of my understanding there was no 2018 HS3x upgrade for the Cosecant. I've bugged Gordon regularly for any other more recent updates over the years and as mid last year the only update (for this DAC) he was working on getting boards squared away for was a N2 upgrade he called it - which was basically a non-oversampling (NOS) option. To the best of my knowledge, this DAC is the latest Sabre DAC based version/spec. Feel free to bug Gordon to see if anything has changed since I last talked to him mid last year. Cheers Rich
