My knowledge of an amplifiers inner workings is limited, though I do have a lot of experience using different types of amps. While I like the sound of tube amps better, I really appreciate the reliability of many solid-state versions-- and they sound pretty darn good too
Around 3:20 in the video, Marco DeVirgiliis says that the MM amps are different from Markbass amps. It's difficult to understand exactly what he's saying at times, but he does mention the speakers, cab and something about the internals. Earlier in the video he also mentions that the preamp is solid state, with valves in the power section.
I've always wondered the end result of Class A/B vs Class D when it comes to solid state power and bass amplifiers. Most the bass amps I have are older Carvin units with toroids and Class A/B power sections. I do have a smaller 250 Watt Carvin that is class D, and a Power amp that is Class D.
Ahh yes, Carvin. Their gear has been a staple of mine since the mid 1990s. Currently, a BRX 2x10 cab sits below my Mesa D800, and on the other side of my desk I have a MB250 15" combo with a dark brown "western" covering. That little Carvin has been a real workhorse over the last six years or so; I sometimes forget to turn it off after muting it, and a day or two later realize that it's been on all that time(!) Even so, it still keeps truckin'
Sadly, since the split in the company (Carvin/Kiesel) the Carvin offerings have been thinned way down and most of--
if not all of it-- is no longer USA made.
Anyway...
I have seen a few of the newer MM speaker cabinets available here in the US, with "Audiophile" painted on the lower front grill, but haven't seen any of the heads yet. I really should set aside a few bucks to have ready when I do find one
