I can't help it lately seeing these threads about the Origins and the SV20's. I am torn about these but still want to get another. I don't think I gave the Origin20 a good chance but the SV20 is going to be loud and expensive. I need to unload some speakers and get the ones I love (G1275's) but I still want to get one of these too. If Marshall made a Vietnamese model of the studio heads I could've had all three. There is no middle ground model that is great and affordable. I really have not heard really good clips of either amp honestly. Good AC/DC, Judas Priest, ripping blues etc... The Origin sounded good with the SD-1 but not with my TS-9 which was a disapointment. I would get another Bugera PS-1 probably because yes it worked for the studio heads fine. I always wanted an 1987X but could never afford one and it was loud. That was why I got a 1960 and modded it. It is good but the speakers are the problem now with that. I need more convincing. I want a great vintage tone not a clean tone and have to use pedals.
