I have tube amplifier plugins to use if I wish but that means playing files from my computer. I rarely do that.
I do have a valve amp which I can use but usually leave it not connected but on top of my record cabinet to enjoy its styling. It comes out from time to time but I can't say I notice any particularly attractive aspect to the sound. Mind you, I play it through horns which have a high impedance so its effect on the FR will be small.
Just for the fun of it how good are these? I'm always on my PC so i'd love to give them a try i guess its probably just a EQ? Is their a way to make everything sound like that with a on and off switch?
