Ken, 103 for you ! Silver or Black ? [emoji6]
The amp:
SM-011 in Class A mode.
But you still like the 102's better than the 011's?

Its not New , Krell started using a similar bias method in the early 90's , called it plateau bias , this is just another variation of that Bias scheme ...
Oh I know, I just think the tech is pretty cool.

100 Watts of Class A is pretty special, so that is the reason, BUT within the 40 Watt Class A limits of the O11's it would be a toss up and personal preference. If I could drive the speakers with the 011's in Class A that I was using then the form factor of the 011's is great to live with vs. the BIG 102's. Although the 102's look awful cool, once you get them in place.
Here is a better way of saying it, if the 011's could drive your speakers in Class A, then you would never lust for the 102's or probably even want them as the 011's in Class A are that good. BUT if you needed more power, that is when you would be wishing for the 102's.
Although to be clear the 011's are running at 400 Watts into a Magico 4 0hm load, with the first 40 Watts running in class A and then switching over to A/B (Intelligent Class A) when you select Class A via the remote or menu. Most of the time at normal listening levels you will not be going over the 40 Watts of Class A.
I would say that the ICA circuit in the 011's sounds little more "sophisticated" and probably more transparent and maybe higher resolution than than the 102's BUT the 102's are so room encompassing that you don't notice any lack of resolution vs. the 011's.
Really the only way to know the difference is to hear both the 011's and the 102's and even then it's confusing because they both sound so good.
Hi Bob,
Could you further explain the two different settings on the Vitus SM-011 monoblocks? How much Class A power (RMS) does each setting provide into 8 ohms and 4 ohms? How much Class AB power (RMS) does each setting provide into 8 ohms and 4 ohms?
Thanks,
Ken
Hi Ken,
First, when the SM011's are put into pure Class A mode via the remote or the menu through the display on the amp, the amps deliver 40 Watts of Class A mode before "sliding" to A/B operation. Probably 90%+ of the time the amps are delivering Class A sound. In this mode the amps deliver 200Watts into 8 ohms and 400Watts into 4ohms. The first 40 Watts being pure Class A....they sound very powerful and you NEVER notice any "sliding" from A/AB.
You are only going to slide out of class A when you push the amps and you never notice it. The amps get VERY warm running in this mode and really sound like class A amps.
If you set the amps via the remote or the menu to A/B then they deliver 200W-80ohm, 400W-4ohm, never going into Class A. Once you hear them Class A you would never listen in A/B other than for background listening.
Besides the Class A/AB modes in the 011's, there are two other settings available via the menu, not accessible via the remote. The first and default setting is the "007" setting. This is the more natural normal Class A setting.
For hard rock or personal preference, where someone might want a more forward and possibly "edgy" (in a good way) sound, there is the other mode which is called "Rambo".
These two settings act independently from the A and A/B settings.
Please just ask questions if I am not clear....thx
Btw, I will be having dinner and meeting with Hans Vitus at Munich this Thursday, so if you have any specific questions let me know and I will get the answers from "the Viking"
