My dac has a volume control but I prefer the sound of my system with my tube preamp in the mix. I don’t think it’s better I just prefer the sound of a tube preamp with a ss amp. I always have. Plus, I have multiple sources and I use the HT bypass feature so that my HT processor can use the same speakers and amp. Would I buy a preamp if I didn’t want tubes and had no need for input switching? Probably not
