Well, I thought it was past due for me to post another set of impressions. I have been playing both the Totems and the Micro Walsh Talls as much as possible. I've been alternating the two speakers, pretty much one week on and one week off. Here are some impressions...
Both speakers are quite impressive in their own way. The Totems have tight, ample base, particularly for their diminutive size... there is some real magic going on there, for sure. :-) Also, with the right source material, the Totems are capable of throwing quite a large, holographic soundstage.
The Totems also have a quality that I'm not sure how to express, let alone evaluate. At this stage of their break in, they seem to express a very detailed, "transparent" quality. What is unclear to me is whether this is really neutral or a rather bright/forward tilt. Ultimately, I think that the way you feel about the Arro will be more a matter of personal taste than anything else.
Although I definitely see the great strengths of the Totems, I am still, at this stage of the game, somewhat more drawn to the Micro Walsh Talls. For one thing,they are capable of generating some truly profound bass notes... beyond "bass notes," it would be more accurate to say "bass energy." When the source material calls for thunder, these things can really thunder! I can understand why someone commented that John, the owner of Ohm, says that one some people hear them, they think there must be a subwoofer hidden somewhere. :-)
Another thing that the Micro Walsh Talls have going for them is something that, as trite a word as this is, I would call "coherency." The music hangs together in a seamless fashion that is quite striking. I really don't know how else to describe it.
Finally, the Micro Walsh Talls have the ability, with the right material, to not only throw a wide and deep soundstage, but to really reach out TOWARD YOU and fill the room with music. It's very involving, and sometimes, almost spooky.
Right now, I would say that Totems do have a bit of an edge, all things considered, in that "transparency" department, but I suspect that the Micro Walsh Talls still have some opening up to do, and that the Totems still have some settling down to do.
For now, over and out...
