Toggling Integrated Amp Input During Music Playback

I have multiple source components hooked into my Musical Fidelity M6si. If upon listening to source A, I change my preference and decide to listen to source B, I lower the volume completely, toggle the input and then raise the volume once again.

However, after a recent acquisition of new gear (Schiit Yggdrasil), in order to more accurately do an A/B comparison, I elected to toggle inputs (any, i.e. between RCA1 -RCA2 ,RCA3-XLR, etc.) while the volume is raised (say 85db or so levels, 9 O'Clock on the volume dial). My amp in no way "complained" as I did so.

I'm just wondering if there is a technical problem that could result in damaging the amplifier by doing this. I liken to the question to playing a spot frequency tone at loud volume and damaging a speaker.

All input is welcome. Thank you.

 no damage as long as they are not to loud to damage your speakers if you went from nothing playing to full tilt.

Guys, I appreciate your response(s), however, they do not address my question.

The position of my pot is always right next to my listening chair.

Usually an XLR coomection will have more gain.

Having the volume control in the same position only works if the sources you are using have the same output voltage. Have you checked that? Higher voltage means more volume at the same position of your pot.
Yes, output voltages are the same (as reported by manufacturers specs).

unless your sources are level matched (exact same output voltage), you are not level matched anyway. Considering you are switching between RCA and XLR inputs, it is unlikely that your sources are level matched.

Did not switch between RCA / XLR for testing components A/B. I only used that example because I have the Yggy hooked to my am via *both* XLR and RCA. So I did switch to compare XLR/RCA from the same device. Nevertheless, my thread question regarding potential amp impact still applies.

I was asked (privately) why I do not simply lower the volume before switching inputs. Good question and very much appreciated.

Answer:

Because that invalidates a true A/B, because I cannot reliably return the volume control to the exact same position.
