Very likely your DAC was simply running out of current at the higher sample rates. You need to remeber that the DAC consumes more current the higher the sample rate goes.

Thanks for chiming in Russ. Brian suggested as much in an email. I'm using an LCDPS to power the DAC. How would you suggest I check, or increase the current?

I would like some feedback from some of you folks here:

My thoughts on miniature coaxial RF connectors

Cheers!

What is the status for the XMOS USB-interface?

Hey Guys! I don't have plans to upgrade my B2 with tridents at this time, but I'm wondering if in like 2 years I change my mind, what are the chances of them being still available?

Default tech ?

Recently, I am trying a nCore class D amp with my B-II/Legato (direct connection, balanced). For the first time, the noise floor of the amp is below that of the DAC.
Now I find that there is a clakkity/clak sounding floor of my DAC (sounds kind of like a train track sound). Admittedly, this is way down in level, but I think the floor should be smoother than this?
I put the B-II board in mute, and the sound goes away to reveal a smooth, and very low, noise floor of the Legato (nice Russ).
Before I go on, perhaps chasing wild geese, is a spiky noise floor normal for the B-II, or should I continue to investigate further to try and eliminate it?
Thanks for any insight.

A sound like that sounds like it could EMI or some form of HF oscilation (after the IV). That certainly should not actually be coming from the DAC unless for some reason it is enbedded in the digital signal itself, which is possible. It also could be that your amp is very sensitive to HF, and you may need more aggressive low pass filtering. Some class D amps are very prone to this.
