Class D amps have such a nice tube like sound...or..many companies have the pre amp 2ax7 or whatever its called in there. My Mark Bass has this and it sounds so much like a full tube amp....But....the all tube head will always be around, believe me.
I really, really don't get it when people say "My Mark Bass has this and it sounds so much like a full tube amp" or the person last week who I replied to on another thread claiming the same about his Fender Rumble
ALL class D . I have never heard ether of these two Amps put out anything remotely tube sounding. The mark bass heads with tube sound very class D to me, the tube doesn't really add anything. OK they have the benefits of being loud, light and clean sounding (If you like that kinda thing), but that's just it, they sound sterile to me, characterless!
I would love to use an all tube rig all of the time, and indeed own a SVT all tube head, (its broken right now. its also 26 years old) but the expense puts them a bit out of reach for me. I also settle for a hybrid, its a compromise! Not as sterile as a Class D, but definitely not a full fat tube amp.
I demo all sorts of kit for people in my local music shop, I get to extensively test and even record with many amps in the back room of the shop, and trust me not all tube amps sound alike, but they all have a character, even if its just the pre to a degree. Its a colour to the richness of the sound.... SS amps just don't have this!
I think you should go try some full tubes and see what I mean.
To all the class D mini amp queens.....
Are we all getting that lazy that lugging a heavy amp a few feet from the van to the venue and back to the van is an issue?
I laugh at The Li'l tiny overtone free and harmonically lacking class D's. They are just toys!
