Interestingly enough, I went through the exact same quandary just a year or so ago. I too owned the Revel Studios, (a very good, all around, speaker that had no real weaknesses, but was not truly a great speaker, as it was not great in any one category either at least IMHO anyway). I did have some constraints to my choices, which eliminated some speakers, as my wife really did not want me to have really tall speakers. (She loved it when I bought my Revel Studios, as they were much shorter than my previous speakers, the Martin Logan Sequel IIs.) Nor did she want really big (wide) speakers, such as the Quad ESL speakers. (So, my first choice would probably have been some reconditioned Apogee Diva speakers, as I loved those, but they would have gotten me divorced! Plus having Apogee out of business was a deterrent too.)
(I should point out, that at this point in time, my friend, (whose system's sound I love, and who has similar sonic tastes as my own), and who used to own the Avalon Eidolons, had upgraded to the Rockport Antares speakers, which is as close to the perfect speaker as I have heard, at least in a dynamic type of speaker. They are a very, very transparent speaker, with little to no weaknesses. Their imaging and soundstaging is fantastic. They have a deep, tight bass response, a lovely mid-range, and an extended and very refined treble response. Since I could not afford to get those, (they were $45K new), I wanted something as similar to those as I could afford.)
So, with those considerations, I contemplated several speakers, including:
The obvious upgrade, the Revel Salon, as that was a true full range speaker. But, after five years with the Studios, I really wanted something different, both aesthetically, (even though I did, and still do, like its stylish and modern looks), as well as sonically. (Basically, the Salon is just a Studio with deeper bass, at least IMHO.)
The second obvious choice, (for me anyway), was the Avalon Eidolons. These are wonderful speakers, (and great looking too!), but they just lacked the bottom end to be a truly great (full range) speaker. (Their bass response was no better, and maybe not even as good as the Studios.) Although, I do feel they are a great speaker, just not a great full range speaker.
The Wilson WP 8 was another alternative, but these, for some reason, just did not float my boat, either aesthetically, or sonically. Aesthetically, they look very modern and clean looking, but a bit too robotic, and sterile looking for my tastes. (i.e. they are not as stylish as I would like.) And sonically, they sounded somewhat similar to my Studios, (detailed and somewhat analytical), and I was looking for something that just sounded a bit different, (i.e. more musical, is the best way I can describe it).
I thought about the EgglestonWorks Andra II speakers as I had heard nothing but good things about them. But in looking at them in the pictures, I really did not like their looks that much. Their shape had a kind of a barn look to them, and none of the pictures ever showed them with their grills on, and I prefer to have grills on my speakers, as I dislike looking at the drivers, particularly the woofers. And, I have kids over occasionally, so grills keep little fingers off the drivers. (But, most speakers grills either affect the sonics or dont look that great, or both. (The Revel Studios had a nice grill covering the woofers, which I always liked, and which did not affect the sonics.) But, in desperation, I reconsidered them, when a local pair showed up on Audiogon for a really good price. I went to the sellers house and looked at them, and they looked much nicer in person than they do in the pictures. The black granite sides really class them up in person. (And the speakers come with really nice looking grills, and they are designed to not affect the sonics at all.) So, I spoke with the seller, and he agreed to let me borrow them to try in my system. (A totally classy seller by the way! Way to go Richard!!!!)
I took them home and set them up and listened to them for the weekend. By Monday morning I had decided these were the speakers for me. They had all the transparency that the Eidolons had. They had that last little bit of bass response that most supposedly full range speakers lack. The mid-range was very nice, and made vocals really come to life. The treble was well extended and much more refined than the Studios were. (FYI, they have the same Isotar tweeter that my friends Rockport Antares has.) And they imaged and soundstaged very similarly to the Antares as well. (In fact, I look at the Andra II speakers as being the little brother to the Rockport Antares. The Antares are built slightly better, (but then again, NO speaker is built as nice as the Rockports are, IMHO), look slightly better, (I love their looks), and sound slightly better (they are just a bit more neutral sounding that then Andra II speakers). But their similarities outnumber there differences, and that was exactly what I was looking for.
(Note: The only downside to the Andra II speakers is that they do have a bit of a mid-bass hump. I solved this via room treatments, (i.e. using a bass trap and echobusters in the corners), as well as (possibly) via my speaker cables, Nordost Valhallas. (I say possibly the speaker cables helped, because when I was putting in my room treatments I also upgraded the speaker cables at the same time, and I can not tell how much they helped. I have heard that some people consider the Valhallas to be slightly lean in the mid-bass, so maybe they helped.) My system has never sounded better, and I am pretty much through upgrading my system now. It also helps to have some beefy power amps in order to drive the 12 twin (Isobaric) woofers. I use the 200 wpc Lamm M2.1 hybrid monoblock amps. (Your Krell amp should work nicely as well.)
Well, I hope that helped.
(I am home waiting for a repair man, and had lots of time to write on and on, so if this was long winded, I apologize.)
