Looking for speaker recommendations under $5K

Greetings. After 51 years on Earth, I'm new to the world of high end home audio. Always knew you guys were out there, but was never did anything about it. Suffice it to say I thought my Pioneer L80t3's sounded great paired with a Denon AVR 1803 receiver. I had no idea what I was missing.

Well, I bumped into an old friend (who I later determined is a fellow Audiogoner) at the Phil Lesh concerts at the Nokia Theater in NYC last Fall, and next thing you know I've got a pair of Energy 2.2i's (purchased new on what I now know was a closeout from Audio Advisor) connected to a Pioneer VSX 59TXi receiver and a Pioneer DV 79AVi DVD player (both Pioneer units purchased here on Audiogon). Also have a Hsu VTF3 MK3 sub (also purchased on Audiogon). Not the greatest setup, but night and day compared to what I had. I'm using some hand twisted/sanded magnet wire (ala Anti-Cables) for speaker cables. I have the speakers bi-amped - although I'm not quite sure why. DVD player is connected via Firewire and via MIT Terminator2 interconnects. Sub is connected via Blue Jeans LC-1 subwoofer cable.

My listening room is 20x25. Thin carpet over concrete floor. Plywood walls all around. Believe it or not, room acoustics are good. (Or so I think LOL) I listen to lots of Grateful Dead, but more importantly to any high quality recording I can get my hands on. Everything from Dire Straights to Eric Clapton to 10,000 Maniacs to Alice in Chains to Frank Sinatra to Miles Davis. Definitely into acoustic music. I buy all the remasters of the 70's music I can get my hands on, as well SACD or DVD Audio discs within reason (which rules out Neil Young's Harvest - which is going for $100, as is Frank Sinatra's Live at the Sands).

So, now that I have a taste of your world, I'm wondering what I might be missing. I would be willing to spend $5,000 on a new (or used) pair of speakers - if doing so will make a noticeable improvement. And I'll buy a new preamp and/or amplifier if it will make a noticeable difference.

One of the reasons for the timing of this inquiry is the fact it seems Energy will be unable to provide warranty support for my speakers. I don't know exactly what the problem is, but I noticed what I can only describe as "distortion" when I was playing the Alice in Chains MTV Unplugged DVD the other day. Don't know if its the speakers or some other problem. I have noticed some very minor "anomalies" in the past, but never could put my finger on any specific problem. I have been writing it off as "diginoise" (I don't know if there even is such a thing) or to my ever-declining sense of hearing. Or perhaps to the auditory hallucinations brought on by having attended over 300 Grateful Dead concerts. Fortunately, 99.8% of the time the speakers sound fantastic.

However, well prior to hearing this "distortion," I have been scouring this site and every other site I can find to try to get some idea of what "upgrades" I should be considering. For some inexplicable reason, I have a desire to acquire a pair of floor standing speakers. (That desire has nothing to do with the size - or lack thereof - of any part of my anatomy. LOL) I gave the Anthony Gallo 3.1 a listen recently. Sounded real nice, but didn't have a reference disc with me to make a meaningful comparison. Plus, the exposed nature of the drivers in those speakers probably wouldn't be the best idea considering I have a 12 year old and a 13 year old who, along with their friends, like to play on their Xbox in my listening room.

So, I would really like to hear some suggestions/comments/criticisms.

Thanks for listening.
"But Mikey Fremer liked the Pioneer VSX 59TXi. It's been blessed by one of the high priests of the faith."
With appoloiges to the late great Frank Zappa: "...And remember kids, there's a difference between kneeling down and bending over."
Not trying to hijack this thread but I have a question for Unsound. Wouldn't you agree that having $20,000,000 does indeed make a heavenly bank account? :)
I am also a big fan of dipole planer speakers. So much so that I do not see myself going back to box enclosed speakers.

Take a look at Emerald Physics CS-2's, they can be had for less than $1,900 used. They require bi-amping but you are already there using your receiver.

Then take the money left and get a good stand alone DAC.
The "big difference between kneeling down and bending over" quote is from the song Heavenly Bank Account. You Are What You Is is a killer album.
