Any reports on the Lina 2.0 SQ?

The DAC board of Lina is not more modern than any Apex model as the hardware upgrade involved replacing that board.

But it actually is more modern:

A good place to start is to compare the Xilinx FPGA chip logic cell capacities between the Lina and the Bartok on the Ring DAC board.

The Bartok I believe has a pair of Spartan-3 chips between the left and right channel. If I’m not mistaken, it uses the XC32S100E chips for a total programmable logic cell capacity of 4,320.

If dCS’ “Making of Lina ” YouTube video shows the genuine Lina being manufactured, then it would seem dCS has pulled out all the stops and used the top-of-the-line Artix-7 XC7A200T chip with its whopping 215,360 Logic Cells. That’s a $500 Chip!

Lina upgrade to 2.0 possibly?

So… I was wondering why dCS would use such a high-capacity FPGA on the Lina; made sense when I looked properly at the Lina DAC Circuit boards; Unlike the rest of the dCS families, Lina doesn’t have a separate Control board with FPGAs, so it would appear this one big FPGA is actually doing all DSP duties, though now in conjunction with an XMOS chip; input processing, filters, mapper, etc. etc. All of which suggests Lina has quite a different evolutionary firmware stream from the rest of the dCS…

Lina upgrade to 2.0 possibly?

If the Lina is getting this level of technology, the replacement for the Vivaldi (whenever that happens) could be quite formidable
