I've used a lot of different kind of scopes, old and new, analog & digital. Of the scopes I currently have on hand, an old LeCroy WavePro is what I would consider to be quite noisy and borderline unacceptable.
At my last place, I also acquired a Rigol, not exactly your model, but similar. The first thing I noticed was the audible noise. Was it noisier than the LeCroy? Possibly not, but given the sheer size & age of the LeCroy, I kind of expect it to be a bit loud. But not for the Rigol. It was unacceptable, loud enough that I decided not to procure it for my own personal oscilloscope despite the extra low cost. I'd rather eBay for an old TDS754 or something similar before I spring for one of those new Rigol's. I spoke with the Rigol rep about that and he assured me the newer 2000 & 4000 series were significantly quieter, but I've not seen them myself.
I have even used old Tektronix Type 547/545 era of scopes and I don't remember it being as annoying as the Rigol. (Again, that might be expectation for what is a near 50 year old scope that rolls on its own massive cart).
Most of the recent HP/Agilent/Keysight , Tektronix, Yokogawa scopes I've tried are fairly quite and nowhere near the Rigol.
