I've $4k to spend on used speakers for big room


I'm looking for a pair of speakers for a relatively large room wtih vaulted ceilings. The room has a very unusual dome shape, and seems to be a nice venue for a good pair of speakers (you can see the room in my virtual system). I had great success with Audio Physic Virgo II, moved to Focal JM Lab Diva Utopia Be, and then downsized am currently using my roommate's Definitive Audio Mythos. Just to mentin, I've tried horns (Acuhorn Biancore 155) and hated them.

My current amp is Red Wine Audio 30.2, which is a 30wpc battery powered class T amp. It's quite nice, and may be nicer still if I can match it to the right speakers, but I'm not married to it. That said, I'm open to an eventual amp change if necessary (up to $4k by the end of the year). I use the system mostly for music but also for watching DVDs. I may add a sub later if required too, but no time soon. Music taste is very broad - mostly rock, but some classical and pop. I like a system that is dynamic, subtle with great imaging (loved the virgos for this) and one that presents a great degree of air and delicacy. I like visceral power and impact, but not if it's colored or imposing. I like good bass, but only if it's controlled, integrated well and in it's place.

I know these speakers are quite different and I haven't heard most of them, but i've considered:
Harbeth
Tyler Linbrook (some available used nearby - I live in SF Bay Area)
Audio Physic Virgo II or III (haven't heard III and not sure if they would be better than the II)
Emerald Physics
Living Voice
Sonics
WLM

Any insights or opinions greatly appreciated, especially from those who have similar rooms and/or have heard some fo the above speakers, but any opinions on best used speakers for my $4k would be apprecaited.

Thanks!

If your willing to change amplifiers, the big Thiels, in a big room are hard to beat.
I have those Acuhorn running them w First Watt 3 and Modwright 9SE. I love the sound even though love to have more bass - my room is smaller though! You need a planar like MG or ML, but then IMHO your amp will need an upgrade!
Thanks for all the input guys - some great ideas there. Bozsiujj - that's so interesting that you like the Acuhorns. I love the look of them, but I could never get good sound out of them, and I tried everything, and I used them with KR amps, which Acuhorn usually uses for their demos. I loved the KR amps on other speakers.

So, getting back to my speaker question, I have a strange inclination - to get some MBL 121 speaker. They are the omni monitors. Any thoughts on that choice? I can get a good price on them, I've heard and loved the 101e (I know - compltely different speaker and pricepoint, but I liked the midrange and treble on them, which would be similar to the 121), and I could add a sub or two later like the JL Audio. Thoughts?
Domes are a nightmare. Sound actually travels the curve and comes out the opposite side. You will need to hang room treatments
I know - [MBL 101] compltely different speaker and pricepoint, but I liked the midrange and treble on them

If you like midrange and treble on MBL's then you like wide dispersion speakers. Dr Floyd Toole in the 70's found this was pretty much the number one consistent thing about peoples tastes in speakers. The research lead to companies like Energy, Mirage, PSB - often designed with wide midrange dispersion in mind.

The MBL's are limited dynamically. I have also heard the Beolab 5 and they started to get congested at realistic levels.

I am sure you can find some good used speakers in your price range that have wide dispersion.

A used pair of Energy Veritas 2.8's are the ticket ...it will leave you money for a sub (which you may need for HT but probably won't need for music).
