REFERENCE 3 A SPEAKERS

Triangles have top notch soundstage when set up well for that but may not
always depending, like most good imaging speakers.

Cometes go for significantly less than decapos, an excellent value. Things
get more crowded as prices go up. My triangles were the ones that
convinced me that I could live without much larger magnepans. They can
hit well above their size and cost but only if set up right.

I want a speakers that has excellent imaging/soundstage

Nyaudio98,
I have not heard the Reference 3A. But once I had demoed the Triangles at AudioVision in SanFrancisco and they were a bit too bright and forward sounding for my taste. I should mention that they were driven by some solid state gears (probably Rotel). If possible always try to demo a speaker before buying it.

To specifically answer your question Nyaudio98 I would say the Decapos have outstanding soundstaging, when properly set-up and excellent imaging. There are many monitors that image well, so nothing too special there but their soundstaging is very noteworthy of mention, for reasons given above. I would add that, with the right amplifier and source component these speakers can make the music breathe with the energy of a live performance easily resolving the space of the recording venue. Also they work well with all types of music from rock to symphonic. There is no substitute for listening as YMMV.

I was not able to audition speakers so i just took a plunge.

got a set of NIB Cometes for a damn good price and had them for 2 years and was able to sell them for what i paid. I buy used and have had good luck selling things for what i paid for or a little less (rent:)

if you got the change to play
