Manual preamp volume control - Audible Illusions M3B


Is it true that most preamps with remote control have a lot to do with their sound quality?
Do vintage preamps with manual precision volume control have the inherent advantage over modern preamps with remote control?
After a few months of mulling over preamp upgrade, I took a plunge on Audible Illusions M3B preamp after reading some posts on the advantage of manual volume control over remote.
Some, including Michael Fremer, considered AI M3A was one of the best preamp.
" All of this adds up to what is clearly one of the finest-sounding, best-built full-function preamplifiers in the world—and the reviews from around the world reflect that."

M3B is considered much better than M3A. AI still produces M3B (preamp with MM phono) and M3B MC (phono for low output) with no remote control.
If the answer to my two questions are true, when most super charged audiophiles search for holy grails, why they choose preamps with remote control over those with manual control, and prefer convenience over sound quality?

Well, I have at least another 10 years or so to reach to a point that I would not want to get up and change the volume or source. So, I can keep this for next 10 years. Anyway, I can use my second system with remote control.
I’ve read about horrible delays of services from AI, but interestingly Art was very responsive to my simple question through email. Hope he remains that way for another 10 years.
So, by the way, was M3B a noticeable improvement over 3A? I haven’t read anybody saying no.
How does M3B compare with Mac pre?
For my systems - Plinius SA102 (upgraded) and Gershman Grand Avant Garde - M3B outperforms my Plinius M16P and PrimaLuna Dialogue Premium. I still cant' believe a preamp makes this much difference in sound quality.
I don’t know how much it has to do with the volume control, but M3B is a clear winner. This motto applies to M3B IMHO: simple is better, and less is more.
There are different implementations. Some use a motorized potentiometer while other use solid state attenuators. Which one is best? Both also require circuitry for the remote operation which could impact sound quality.
Just off the top of my head...AI uses two separate volume controls and says they are stepped attenuators. So it should have a quality volume pathway. Others can have motorized stepped attenuators so no handicap there either. The one to look out for is digital volume controllers that drop bits to control volume (not really sure they drop bits but some digital signal is dumped and lost). 
Right, they use  Dual-Mono Left & Right Stepped Attenuator Volume Controls.
So, motorized stepped attenuator with remote works pretty much the same as manual control and has no disadvantage on sound?
Is analog volume control the same as motorized stepped attenuator?
How do you know whether a preamp volume is controlled by a motorized stepped attenuator or digital chipset?
"....How do you know whether a preamp volume is controlled by a motorized stepped attenuator or digital chipset?..."

Beats me but the manufacturer usually is very proud of a good volume control and will say something about it in the sales brochure.
