Great post!!! Wow!
Yep, quit the challenge to come up with an idea dor a user interface, develop and test it “this year” (its now November 2020).
Equally testing digital and electronics boards this complex when software isn’t quite done.
Mind you a unit that goes for sale for 3 x the Direct Stream DAC SR, better work flawless when it hits the market.
So give PS Audio the time to do it right.
I do count the boxes and cables. The less the better.
With the amount of dust and a dog in our home housekeeping is a major issue. The more boxes and cables the bigger the housekeeping issue. I enjoy listening to music not cleaning the system.
Again large rooms where you can walk around the system make a big difference, but cramming a lot of gear and cables in confined space is not wise.
It’s going to be two boxes each with their own power cables and power supplies. They will be connected by an optical cable. So, if you want fewer boxes and cables, this new DAC is not what you are looking to get.
That is one correct conclusion.
But you missed the other one which is:
A product is ready to be released when it is released after it is tested and working flawless.
So this is also not a DAC for those who can’t wait till that process is finished, there is no need to push for release dates as the outcome of testing is extremely hard to predict.
Great that PS Audio won Stereophile’s product of the year for the stellar phono device. Also interesting is the DAC of the year that they picked, the HoloAudio May, that has separate power supply vs digital boxes like the future TSS super dac? By the way all the high end Mundorf etc. parts and the workmanship quality seems amazing, all for $5k. Tough competition. But no easy way to try it out.
The Holo design is a certain kind of genius, having a secondary R2R ladder performing live compensation for the non-linearities in the primary R2R ladder based on actual measurements of the component. They claim superb PLL performance too (also using a FIFO buffer and VXCO not entirely unlike what Ted’s DS DAC does). But the comparison with the TSS is a bit apples and oranges IMO.
The two boxes in the TSS both have their own AC-to-DC power supplies internally, where the Holo May has a power supply in one box and all the digital logic as well as the analog output stages in the other box. TSS box 1 is where you connect your digital sources and where all the signal processing is done to produce the DSD256 (IIRC) bitstream that will be physically converted to analog by TSS box 2. The only thing connecting them is a pair of optical data cables that sends a master clock signal from box 2 to box 1, and audio data and output control signals (like ground lifting and analog attenuation setting) from box 1 to box 2.
Uh oh. I’m interested.
