Where do you live? If you are close enough, you can come over and listen. These Towers have upgraded midbass drivers and are better than much of what is out there. They are more revealing and stage much better than any of the Paradigm Studio series I've heard to date. That's just my ear though. The Krell will blow away the Emotiva's. THey aren't in the same league. Forget reviews on things as many really are tainted. When you know the inside stuff in the industry you will realize that as well. Heck good old Sam Tellig is Tom Gillet (see what he did there with the last name?). That's not a bad thing, but to me I know how reviews are often done. Richard at Proac won't even give his speakers up for review as you have to hear them to understand how good they really are. Not everyone's cup of tea as they aren't etchy detailed and they don't use the most expensive driver, but they work with so many electronics. Since you like reviews, I figured I'd post one from a guy who just got a pair (in 2009) and decided to share.
Just scored a Proac Super Tower and Bryston 4b NRB, and WOW.....
I have recently scored a pair of passive Proac Super Tower (floor stand speakers) and a Bryston 4b, all of a sudden the world (of sound) clears up.
These are the bigger brothers of the Proac Studio 100s, they were the flagship of the studio series back in 1990s'. They have been discountinued.
The first word that came to my mind when I listen through them is "effortless". These speakers are very detailed, much more detailed than my trusted Focal Solo 6 BE. But listening through them does not feel like being overwhelmed by details; it's more like the details are right there, you can just grab it if you want to, just like real world, nothing needs to strike you for attention (I don't know if this makes any sense).
One thing I found very interesting is that the Focals are very dry, even though they represents excellent space, mixing reverb on them still need a lot of work. The Proacs are much wetter (not in the wrong way), space sound extremely real, the depth is so deep it's eerie. I listened to a lot of Jazz and classical recordings through these, these speakers made the room disappear, although small recording space will sound small, and bad recordings sound just bad. And it's sooo easy to spot out the bad frequencies you have an urge to just grab an EQ and correct them.
The thing that amazes me most is even though each speaker has 2 woofers and 1 tweeter, my 60 Watt/channel Marantz amp is able to drive them with ease. Although I got the Bryston for the ultimate cleanliness. On the Bryston, I've heard so many contradicting review about it - too bright, too harsh, very clean and musical, very deep... and I found them all correct.
The first time I plugged the Bryston into the speakers it sounded so bright and thin I almost wanted to unplug and return it. There was no depth. However after about half an hour or so the machine was at about body temperature, the sound changed.
So now I have the Marantz amp just so I can listen to the speakers with color. Actually for the first time I realized the Marantz amp (1120, made in 1975, one of the original Marantz models) actually sounded pretty good. It did not fair well with any other speakers I paired with them, both as amp or preamp.
I used to think my Benchmark DAC1 sounded pretty close to the Prism Orpheus(while definetly not as good, but within 5%) on the Focals, now the difference is much more. I can hear so much more depth with the Orpheus than the Benchmark.
It's almost bizzar that I prefer listening to them at the ear level at about a foot above the tweeters.
