Have a look at the Mic2496 V2's noise graph, measured with an FFT size of 32K, and you'll see a noise floor of around -138 -- it would be even lower with a 64K FFT.  The Grace Lunatec V3 has similar performance.

Unfortunately Core's graph is the one printed in the application/data sheet for the convertor device depicting optimized maximum performance breadboard and is the most ideal implementation (rarely if ever achieved in real world products), and is NOT the performance graph of Core's actual product. 

So we know nothing about his products implemented performance, only how good it might get if someone using the device covered all bases and then some to get near this documented ideal performance.   

It does look good for marketing purposes, but in reality is NOT his product's performance as is often stated here and elsewhere.

Guy what does this -35 db reference mean? and you know you cant just look at a graph and determine the noise floor with out averaging it out over the whole bandwidth right?

-35 dBu reference is signal level input for 0 dB full scale display on the deck. 

This insures all models tested are at same input gain for recorded level, an apples-to-apples noise comparison not found in most posted of comparisons of input noise.
