Hi guys and thank you so much for your patience and support. This has been a rough year and things are not moving as quickly as I would like.
The PCB layout is done and the analog stage and analog filters, supplies, etc. all bread-boarded and proven. This is going to sound GREAT!!!
I am sending off the PCBs for production today, after double checking all mechanical coordination. This should take about a week to get them back. I will then start assembling and testing the first unit.
The design I settled on for the analog stage is based on both the Elyse DAC and the LS 300 preamp ($10K!). The mod will be offered starting at $1500! You must supply the Cambridge unit.
The design has no capacitors in the signal path. A differential signal is taken directly from the dual mono Wolfson DACs into a fully balanced, transformer coupled, 6922 based circuit. Both RCA and fully balanced XLR outputs are fed via the tube circuitry. The tube stage is powered by our own supply and we are also providing a dedicated supply for the DAC section, also of our own design. Power supply and all analog circuitry is in one box, much like the Transporter. Rectification is SS, not tube, due to space and heat constraints.
The Cambridge CXN is the first 'Swiss Army Knife' unit that I have seen since the Slim Devices Transporter, except the technology and capabilities are FAR beyond! It is a streamer/DAC, not a player, so it won't replace the Oppo 205 in this regard, but for all things digital, streamed or otherwise, this offers a fantastic one-box solution!
Again, I thank you all for your patience and support. I hope that this finds you safe and well!
