Does anyone care to ask an amplifier designer a technical question? My door is open.
Thanks atmosphere.  (I'm still interested in ramtube's view as well).My room is on the smaller side: 15' x 13' wide and I listen at modest volume - typically 70 db to maybe 75, probably 90 at the most if I crank it more to listen from down the hal... 
Magico A3
I can't contribute the experience of an A3 owner.  But FWIW from my own audition of the A3 in a dealer's home (purportedly a room that allowed for smooth bass response):  I found the A3 bass to be very deep and not wanting for a subwoofer.  But I ...

@ramtubesI could really use some help betting a better grasp of amplifier/speaker interaction. Specifically, in what sense a speaker is "easy to drive" for an amplifier.This seems to generally relate to two parameters:1. Speaker sensitivity2. Spea... 
How do you know what a good speaker is?

nonoise,Happy to answer your question.My coworkers have a variety of viewpoints on audio. Some are what I might characterize as "hard nosed engineer" types and others are audiophiles - and somewhat subjectivist - in their spare time. (E.g. they wo...

nonoise,You are yet again whacking a strawman - repeating the same misrepresentations and fallacies as you have before in these conversations.  Your last paragraph especially displays this. (Nothing I have written entails the wholesale abandonment...

I'm not the one who introduced the term "placebo" and would not - as I had clearly stated - simply attributed either real audible results or imagined audio results to the "placebo effect."  As I keep mentioning, we suffer a range of perceptual bia...

@mkgus,I think nonoise is getting upset with you because you are denying his very reality without having any experience with it via sitting in a arm chair 500 miles away removed from his situation and then going on to cite how fallable the mind is...

nonoiseWhy do reasonable questions upset you?Why do you think it’s perfectly fine that you declare to the crowd that you KNOW your position is correct and that you know you exhibit no bias effect when evaluating cables. Yet if your claim is at all... 
Spatials = Done for now!
Wonderful to read that you are so happy with your new purchase.It is wise to have chosen the phrase “done for NOW.”No one could trust an audiophile who said “just got new speakers and I’ll be satisfied for life with them!”  ;-)

nonoiseThe only scientific evidence I can steer you to is empirically derived: People who go to psychics also have "empirically derived" conclusions.They experienced the fact the psychic simply knew things about them that the purported psychic  "c...

@mrdecibelI realize you've deemed me not worth your time.But just in case you are feeling generous...my time and experience in the field has allowed me to train myself to hear very minute differences amongst all related items in audio. Could you ...

rosami,I have extensive experience with the 3.7 and 2.7 and the older big CS6.I am betting that the thinness you heard was very likely in the set up of the speakers.  As with many speakers, I found I could dial in the size and richness of vocal an...

I was reading an old Audio Critic magazine pdf recently. For those that aren’t familiar, it was run by notoriously critical and cranky editor Peter Aczel who was devoted to repudiating "audiophile myths" via appeal to sound engineering and science...
