At this very moment, I currently have a set of Sttafs, Forests, and Mani-2 Signatures in my abode. I also ran a set of Hawks roughly two or so years ago. They all make great music. You could say that I dig on the Totem sound.
Im drawn to each and every speaker listed above. Each one of them is different and brings something truly unique to the table. That said, I do not necessarily agree with some of the notions that you will attain exceptional aural gains as you ascend on up the Totem pole. For example;
The Mani-2 Signatures are awesome loudspeakers, no doubt about it. However, they are also very finicky monitors that come with a laundry list of requirements to strut their stuff. First, you need the right space. Next, you will need high end components (cha ching), most notably a beast of an amplifier (cha ching), great high quality stands (cha ching) and then you need to have lots of patience for room placement and set-up. You dont pick where the Mani-2 goes, it will tell you when its happy. Its something of a diva, but when you get everything working just right, boy can she sing. With that said, if youre a rocker, you may actually prefer the Sttaf or the Forest.
The Sttaf is an under-rated speaker. Most people think its a drop and plop product, but actually, it too can be pretty exacting. To understand what the Sttaf can do, it needs to be placed in a small, closed off room. It then should be fed a high quality tube amp (and no, Im not referring to Jolida products or things of that nature), along with a good CD player. Once you get them dialed in, you will get amazing tone, along with voicing that will sound pretty damned good even with rock and roll.
Even the Hawk, a speaker which is in my opinion one of Vinces better designs, can be incredibly finicky. Despite sharing similar dimensions with the Sttaf, it requires a big (closed off) room and real high quality tube amplification (such as BAT). When set up right, this speaker is stunning and in my opinion may be the better sounding of the group when it comes to light classical and jazz.
Out of the group, the Forest is by far the most versatile. Its extremely efficient, it works well on virtually all solid state and tube topologies, it performs well in a variety of rooms, is not too fussy with placement and positioning, sports great dynamic range, bass and treble extension, and captures all of the main elements Totem is known for. No, doesnt have the speed and finesse of the Hawk, the balance and musicality of the Mani-2, or the exceptional tone and deep layered soundstage of the Sttaf but its a great all-around loudspeaker thats an easy go-to for most listening situations stereo or HT.
Of course, all of the above is little more than a collection of my own experiences and opinions. Obviously, others may likely share opposing views. Those are mine, so make of em what you will.
Although I admit to not being a big fan of the Bel Canto digital gear - Id say the Forest will be your safest bet. Thats the direction I would point you towards.
