Worth the wait? Buchardt S400's

I own the S400s.  About the sound characteristics, they are as a lot of folks claim.  The sound is much larger than the cabinets would indicate and bass extension is far lower than it should be.  Imaging is very stable and the sound stage is superb.  Instrument separation was acceptable.  I listen to a lot of recordings from the 1930s through the 1950s.  Even with bad ones, the sound is always pleasant enough to enjoy  That cannot be said of all speakers.  For lack of better terms, the S400s sound pleasing and natural never harsh or fatiguing.  There is a lot to like about the S400s. 

Like all loudspeakers, there are some things I would change.  My criticisms are few, though.  I would like a bit more openness on the top-end.  They are a little more "neutral" than I prefer.  Vocals can be a touch muddy at times, also, but I didn't notice it often.  That may have been recording-specific.  Lastly, they are not very efficient so you will need some juice to wake them up.  After seeing your amp description above, that should not be a problem.  I am not singling out the S400s for low-efficiency as many, many stand-mount speakers are similar.  Overall, they get a lot right for under $2,000. 

While I can't determine if you should cancel your order based upon the sound of your current system, there is no harm in keeping your order for the S400s and trying them out. They come with a 30-day in-home trial with free shipping both ways. That should allow you an opportunity to make an accurate decision.   I hope you enjoy them.

Thanks smdesforges,
curious what does your system consist of?
My hesitation comes down to my Vandersteen’s and whether I want to keep such big speakers. I love the look of the s400s and I ordered them in white. What stands are you using for them?

I have a modest but enjoyable system.  I stream Tidal from a Bluesound Node 2i to a Rotel RA-1572 integrated amp via Toslink.  The S400s are on Pangea Audio DS400 stands.  

Vocals being muddy is a general side effect of wide dispersion, if you want clear vocals that cut through everything you want a speaker that has a rise in 3-4k region and has limited dispersion so you are listening to a higher percentage of direct sound. KEF, Revel, Amphion, etc speakers will exhibit this in some recordings as well. This is really the only small downside of a design that has wide dispersion. However since the average listener in psychoacoustic studies prefer wider dispersion and spacious sound over narrow dispersion and clarity/pinpoint imaging, it’s a small trade-off to make.

I listened to them for quite a while at AXPONA and for the most part agree with @smdesforges.  I wanted more transparency and presence.  The bass is great- truly a big speaker sound because of the passive radiator.
I was disappointed because the hype fore these was sky high.  One online reviewer compared them to the Joseph Audio Pulsar.  I am being polite when I say he is not correct about that.  My preferences would lead me elsewhere for the asking price.
