Seeing as there are experienced reviewers on this site; this equipment should be split between them for proper reviewing.
After a period of time, the equipment splits should be properly rotated to the next reviewers in the group.
Sometimes life is sweet.

(the vid will blow your mind, this is a low rez facebook repost of ours).
That's an interesting perspective. I note that you are a commercial member and represent Lamm, but not Vitus. The Australian Distributor represents both Lamm and Vitus and has a very different view of Vitus. I must say I do too, and was impressed enough to buy a Vitus Class A amp.

Firstly here is how Boulder describe their biasing for the Boulder 3050 -
"Bias operation is Class A to full rated output power. A microprocessor controlled bias circuit continually monitors the voltage draw, current draw and load to adjust the bias current as necessary. If a musical transient requiring more bias current is detected, the microprocessor will raise the bias much faster than the audio signal to keep the amplifier operating within the Class A window. After the transient has passed, it will then gently lower the bias in a decreasing analog manner over a period of 28 seconds until another transient peak is detected. This has the benefit of keeping the 3050 operating in full Class A mode without the drawbacks of massive power consumption, excessive heat generation and the audible steps or “sliding” of other active bias management systems."
That is a point of difference for Boulder, however Vitus do not change the bias based on input signal amplitude – that has nothing to do with real Class A. I prefer this purist approach which yields amazingly pure and real sound. In regard to the Class A specs, I have attached the data sheet below fyi

Playing at ave 75db? That's a whisper to me & I m not impress with the speakers. However both amp & speakers are gorgeous though I prefer to ogle at the daughter
In contemplating how best to answer you question XV, I reviewed Boulder's technical white paper for the Boulder 3050 which described Boulder's own form of intelligent Class A bias. Boulder describe their biasing for the 3050 as follows -
"Bias operation is Class A to full rated output power. A microprocessor controlled bias circuit continually monitors the voltage draw, current draw and load to adjust the bias current as necessary. If a musical transient requiring more bias current is detected, the microprocessor will raise the bias much faster than the audio signal to keep the amplifier operating within the Class A window. After the transient has passed, it will then gently lower the bias in a decreasing analog manner over a period of 28 seconds until another transient peak is detected. This has the benefit of keeping the 3050 operating in full Class A mode without the drawbacks of massive power consumption, excessive heat generation and the audible steps or “sliding” of other active bias management systems."
I suspect Vitus are doing a similar thing with the MP-S201, though to their own design. In regard to the Class A specs, I have attached the data sheet below fyi

Do not know much abt amp technicality except what Vitus told me when we had dinner with him at Day 2. It seems the amp perform best when the temp is kept at about 55 centigrade. Friendly guy. I m sure if u email him , he would be more than willing to explain to you about the amp
This is merely my 2 cents worth of opinion. My top 3 rooms in no particular order ( excluding Magico Ultimate , not sitting at centre position & too crowded to listen properly )
1. Goebel high end - Goebel Époque Reference with an interesting 9 layered bending wave driver & passive radiators. The chassis made of solid aluminium weighing 180kg. The bass tower - Époque Baforce with a weight of 340kg . It's this bass tower that captivated me . Pre & power , analog domain , cabling by Goebel. Each piece of speaker retail for euro 87.5k
2. Marten supreme 2 ( wired with 60m of Jorma Statement speaker cables), euro 390k powered by Dartzeel nhb -458 Monoblock with expensive Jorma Statement speaker cables ( about usd 40k for 8 ft - separate negative & positive wires)
3. Wolf Von Langa Salon field coil drivers , open baffle speakers with acrylic chassis euro 350k paired with Thomas Mayer exotic looking 211 amp ( silver transformers retailing for Euro 116k . Cheaper buying direct thru vinylsavor )

Sorry somehow orientation of photos changed on posting & when I tried to remove the photo , it ended up as the last photo. I will leave it at that

Audioblazer I have since spoken to Hans and gained some insight into the biasing scheme for this amp, and went back and edited my OP. Therefore I would say your quote does not represent my current view.

Bodhi, excellent. Now that u have spoke to Hans , maybe u can share your current view
