The gain is on the low side. 40 - 60 is what I run and it’s a bit louder with 6 volt tubes at the 5ma bias setting. Of course there are many other factors such as speaker efficiency, room setup and XLR vs single ended connections, with the former 6db louder. My Pass XP-22 sounded appropriately loud at 65 - 80 out of 90, the upper limit I think. Now the ARC Ref 6 I’ve had recently will blow me back in my chair at 35 out of 100 or whatever it’s limit is!

I’m wondering about the volume control on my preamp. I have to run mine at at least 40 on the dial. At that level you can have a conversation. It takes to 25 to even hear it. Normal or not? Amp is 375 WPC.
