Haha, yeah the beep is a bit loud! Glad you are happy with your A1 purchase.
I saw a posting online about A1 users applying dry PTFE lubricant in the grooves of the rails to make the seat a bit quieter. I gave it a try and I noticed the difference. It goes on wet, but dried after about 20 minutes. Since it's a dry lube, it doesn't attract dirt or dust. Something to keep in mind.
