Unprofessional equipment?? What does that mean?

Hi folks,

I'm in process of applying to be a pro here and got the feedback - and then just got rejected on the basis of:

"1.) Unprofessional equipment- It sounds as if the audio was not recorded with professional equipment. Please ensure you are using a professional microphone and equipment to record properly."

I don't get it since I have a professional studio from which I've booked a lot of work. I have an AKG Condensor Mic, Scarlet 2i2 preamp and Studio one as my DAW.

I've yet to get whoever made this call to elaborate - so if there is some sort of issue, I could correct it. This feedback is not actionable unless I know specifically what you mean.

Also - is there a more efficient way to respond to feedback for elaboration?

Thanks in advance. I'd really like to know what was meant by whoever made that call.

Here's a link to what I submitted.
