Can anyone who has heard these speakers or these above brands in particular put in a few words the sonic/sound signature of the above in terms of bright/clinical/dynamic/warm/smooth/musical etc.
The two Spendors are probably going to be the most limited in terms of their LF driver size, and as mentioned, being sealed cabinets they're going to struggle with the likes of his musical tastes. I would say those particular Spendors tend to suit 'real' instruments, particularly the likes of string quartets and woodwind instruments. Because of their small bass driver and relatively small cabinet volume, they will come across as lean, but are very tuneful and fast, and are very easy to place. The SA1 is the better speaker, but the S3/5R2 comes pretty close.
The ATC's will be similar to the Spendors in some respects, but their bigger LF driver packs more of a punch. Again, their sealed design does mean they're not going to reach the loest notes, but they are very articulate like the Spendors, but sound meatier. The SCM11's and the SA1'a and S3/5r2's are naturally inefficient due to their sealed cabinet, so do require a dynamic ampifier to 'bring them to life'. None of these will be the best for low level listening (again, a usual drawback of being a low efficiency, sealed design).
The DB1i's are more efficient, and are probably the most energetic and lively sounding of this bunch, making them one of the better choices for low level listening. Even though they're front ported, they will like a little bit of space to breathe, especially if higher volumes are required. They do have a bit of warmth to them, more so than those previously mentioned, and this along with their lively sound gives them probably the sweetest sound of the bunch.
The ProAcs have a bit of an advantage due to their cabinet volume (as does the ATC, but it's sort of cancelled out as they're sealed), and seem to possess all the positives of the speakers mentioned so far. They're a sweet, slightly warm sounding speaker like the DB1i's, but have better bass and midrange performance than the smaller speakers on this list due to it's larger bass driver, which will reach deeper than the others thanks to the ported design, which is situated on the front, so are easier to place than rear ported speakers.
I'd say they're all 'musical', and all dynamic within their own limitations.
For a waide variety of music, and in particular more demanding music, I'd have to say it's between the ProAcs and the ATC's. Which would be the most ideal depends on his personal tastes, and also his existing amplification, and quite possibly, placement requirements.
I hope this (subjective) view helps
