Frankly I'm astounded.
Owned BA speakers once..Very Briefly.
Rubbish is the honest descriptor.
Harsh and unpleasant is another.
Vandy's ,Like 'em Or not are in an entire different sound quality League.
Their complex driver array/crossover network Does demand a decent quality Amp with Backbone though.
You guys need to get out of the house and hear a few more equipment examples... now and then
In our never-ending quest for better playback, budget-minded in my case, I'm considering replacing my A400s with a pair of 3As, not the Sig, just the 3A.
My concerns are:
a) Will it have a much more narrow sweet spot, horizontally and vertically?
b) Will its bass be that much lower and fuller?
c) Will the mids and treble be too laid back for my Mc MX110Z/MC2120?
d) Must its placement requirements be very intrusive in the room?
Greatly appreciate any advice!

I have both of these. I hadn't heard of Boston A400 when I got them, and the crossover work needed to be done (a separate thread here). At the time I only had Vandersteen model 1C, but by the time I finished with the recap, I had purchased some used Vandersteen 2Ci speakers. When I hooked up the BA speakers, I was surprised by how good they sounded, but after a short time I went back to the Vandersteen speakers in my listening room and the Bostons went to the living room home theater area, where they still reside.
Not that long ago I bought the Vandersteen 3A speakers and really like those over the 2Ci -- while I haven't had compared the two in the same room.
I'm hard pressed to make a description of what I hear in my head.... the Vandersteens just make the music sound more defined with greater clarity. The Bostons sound a little tubbier, but by no means in a way I'd like to leave them behind. At this point, they're also definitely keepers.
It took a year of watching and searching to find the 3As and even then it was an 8 hour drive one way. I'd always pick them first over the Bostons but the Boston A400 is still a great speaker and better than many many others.
You don't say where you're located and probably 99% of members are no where near hear, but you'd be welcome to a listen.
Sitting in the right spot will make them sound better.
I've only heard 2ce Sigs, and that was a few years back in a dealer's listening room, crowded with many pairs of speakers. Not ideal by any means. With that in mind, I wasn't overly impressed with any particular part of the frequency range. I'm sure it's because those 2ce Sigs were forced to sit too far out into the room and too far apart to create a proper soundstage.
My biggest concern is from the experience I had with some Vandy 1b's I owned a while back. In that particular nearfield setup (about 7 feet back), if I stood up from the listening position, the "you are thereness" just collapsed. Probably way too close, looking back on it.
Well, I pulled the trigger on the 3As three weeks ago. Drove 5 hours to Chicago to get them, but got to see family while there, so it was a very worthwhile weekend. Have been awaiting the return of my MC2120 from servicing, and finally got it all going yesterday.
Initial impressions are very favorable. Was a wee bit worried about too soft a presentation with the MX110 tubes and 2120 autoformers. I have intentionally gone in the sweeter/warmer/darker direction with this setup, but luckily for me, it's not too much of a good thing. It sounds like a great match to me, and I feel like I could listen all day long without any fatigue setting in.
Comparing the 3As with the A400s, the Bostons have a bit more midbass bloom but are shy in the lowest region, also the mids and treble are a bit more forward/brighter, but never irritating. The Vandies are an improvement, sure, and I need to invest in some hours of critical listening; however, the Bostons are still very impressive speakers.
I was also concerned if the MC2120's 120 watts would be enough. I did a quick check of the Power Guard lights, and the volume was quite uncomfortably loud, yet clear, by the time they started flashing. Worries alleviated, plenty of wattage for me in this large, open, living room.
Vandersteen speakers, especially the 2 and 3 series, are never impressive upon a quick demo or first listen. In fact, they almost sound bland in comparison to many other higher end speakers. What I like about Vandersteen speakers in general is that everything about their presentation of music is very natural.
Having said that, I've never been a fan of their 1 series, dating back to the 80's and even in their current iteration.
A400's are very good speakers.
I had Vandersteen 1's and A400's beat them easily.
3A's are higher up in line so could be better than A400's.
A400's have come ahead of few pairs of Polk SDA's, Klipsch Forte's, Genesis 3+ and quite a few vintage JBL's so far.
If you do get them, let us know as I can also look out for next upgrade.
