Help with speaker choice


I'm looking to replace my Totem Acoustic Hawks with something that offers heftier bass and more airy highs. The Hawk is an overall great performer with wonderful midrange and surprisingly deep bass for its small footprint, but I'm ready for a more powerful and more sophisticated replacement. I listen exclusively to records, mostly jazz and some rock, and use a solid state 2x50 watt amp, which will also be replaced at some point by a more powerful amp.

I'm looking for speakers that cost up to $5000. The 4 speakers I'm currently considering are:

1. Acoustic Zen Adagio
2. VMPS RM30
3. Vandersteen 3A
4. Silverline Sonatina III

I've only been able to listen to the Vandersteens and I do like the sound quite a lot. I think it's a great speaker for the money, but I've also heard great things about the other speakers. If anyone can offer advice or owns or heard the other performers, I'd really appreciate their feedback.

of your choices, i can vouch for the vmps rm30--very easy to place and drive (93db efficiency), good low end extension and really, really nice transparent highs. your other choices are all well-regarded (i haven't heard the adagios), but i'd look carefully at whether your 50w amp will be sufficient. actually, my other top picks in the 5k range would be either the paradigm signature s8 or psb synchrony; they're both exceptional, with the paradigms perhaps being less placement-critical and a little easier to drive with your lower powered amp. good used deals abound on both of 'em. you're priveleged to be looking at such nice stuff--good luck to you.
Check Hyperion HPS-938 reviews. It had a lot of "Editor's Choice" awards (about 10) and even "Component of the Decade" from Enjoy the Music. It is very resolving and dynamic but at the same time laid back and relaxed. I cannot find CDs that sounds bad with them (warm and musical). Imaging is very good and the midrange is incredible.

New is about $5k - I bought recently 6 month old dealer demo for $3k. Used (without warranty) are even less.

It is also quite efficient (90dB) and delivers a little more power because of 6 ohm impedance.

Unfortunately it is very ugly IMHO (resembles coffin) but you might like it.
I have read some very good things about the Legacy Audio Focus 20/20 loudspeaker

just food for thought, I was salivating when I read about them, I have not heard them...
if you have not considered them, Devore Fidelity Gibbon 9 speakers are phenomenal and offer everything you are looking for and are easy to drive (also tube friendly given benign impedance curve if you are contemplating tubes down the road). should be under $5K used or for dealer demo.
