Hi there, does anyone have (and would mind sharing) either some snippets of vinyl rips they’ve done or frequency plots of them?
I’ve noticed that all my rips have a roll off at about 15k so I’m wondering where this is coming from.  It’s the same across all my carts (which are from a VM540 to an ART9) so there must be something going on either in the Dev or Audacity.  Anyone seen the same or got any advice on where to check?
(This is on a 440 Pro by the way)

Thanks!
Hello there!

I'd be happy to send you some snippets and frequency plots - let me know what you're looking for and how best to get them to you.

If you'd like to cross-check using something other than Audacity, I've found ocenaudio to be very good (and also free).

Hi Ian, good to hear from you - hope all is well! 
A very delayed response here - I posted and then forgot all about it as work suddenly got very busy.

Anyway - to round this one off, I've found the issue.  It was a sample rate mismatch.
The amp is set to 96KHz, and that's what I had Audacity set at.
However... in Audio Midi Setup in MacOS, the Devialet input was set to 44.1 - I've now set that to be the same as the amp and re-ripped a track and previously the freq response had a hard cut off when looking at the spectrum plot in Audacity, now it extends up to 40000Hz.

As a side note, I'm also playing about with a Graham Slee Accession phono stage - it sounds a *lot* better than the Devialet phono input IMO.
Thanks again for the pointers!
