Noob Planar Speaker Advice Needed


My system

Pre/Pro: B&k ref30 (sigh)
Amp: I'm considering an Aragon 4004mkII

Speakers Choices
a) Martin Logans (SL3, clarity, or cls iiz)
b) Magnepan 1.6
C) Eminent Technology LFT8

The cls iiz i've come to understand perform better with tubes. Any comments on these combos or possibilities in the same price range?

(my listening space is poor - and large 15x20 2 story room with an open side wall. But I don't want to try to limit my speaker choice to optimize the room as the room will not be forever. I listen to a little less then half music, little more then half HT - but the sound quality for music is far more important to me. What i want, and have never had, are mids the blow me away - something to make female vocals shine. Hope that's enough on preferences to generate some feedback).

Thanks

i have quads. don't like the sound above 200 hz with any solid state amp. i have tried several. quads and a tube amp is the way to go. the newer quads were assempled in china. don't sound as good as the 63 or esl. i have owned both .

i have a partiality to the martin logan 2 z, but frequencies below 80 hz may be lacking in sound pressure level.

the ets don't integrate well. i also own magie 1.6s. go with the martin logan's
I have some thoughts.

Maggies vs. Stats:

1.) Maggies are not satisfying at low levels, so like me, if you use your system for long periods at background levels (in between actual listening sessions) you probably won't be happy. Electrostats remain full-bodied at low levels.

2.) Maggies can't (practically speaking) be driven with tubes. They require a lot of voltage in each watt of amplifier output, a feature of SS amplifiers. The opposite is true of electrostats. They require current more than voltage, and tube amps deliver more current (per watt) than SS amps.

3.) If you're willing to bi-amp, you can improve the performance of the larger Maggies by putting a tube amp on the ribbon tweeter/midrange, and a ss amp on the bass panels. However, with the (current models of) MartinLogan electrostats, biamping is not necessary since they already have internal ss amps for the woofers, allowing you to use a nice tube amp for the panel -- in oher words, they are sort of "pre-biamped" ;--)

4.) The smaller Maggies are like smaller box (non planar) electrodyamic speakers. Less is just less. Small electrostatic panels sound just like big ones -- as long as the room is also small; and as with all stats, will need some bass supplementation.

5.) All the Maggies except the very small ones, will do best with solid state amplification. If you opt for a MartinLogan hybrid (stat panel + built-in woofer) then for the best result for the dollar, buy one of the recent models with self-powered woofers so you only need a decent tube amp (the external amp) to drive the panels; giving you the best of both worlds without the expense and hassle of using two different kinds of external amps. With an SL-3 for instance, you won't get the best out of the panel with just an SS amp, nor will you get the best bass if you try and get away with just a tube amp (even a big tube amp.)

6.) There are occasionally used Apogees available within your budget. You may find them a bit off the beaten path in popularity, but not in looks or sonics! And they're coming back for two reasons: first the company has been re-started, and second, we now have amplifiers that are easily up to the take of driving them.

That's interesting. I was so taken with the 1.7 at CES that I'm thinking I may want to give them a try, but "not satisfying at low levels" could be a deal breaker.
Drubin, my remark about low level listening with Maggies might not apply to the small(er) models, I don't know because I haven't spent time with any of them.

With the right amplification, they do stand up and sing nicely at higher levels. At lower levels, the ones I'm familiar with sort of thin out at the top and from the lower midrange on down; making it a perfect candidate for a preamp or receiver with a "loudness" control contour circuit.
FWIW - I have heard of the low level listening 'problem' with Maggies before but I think it is only in comparison with something like a Quad ESL which excell at low volume detail. I owned 1.6s for a few years and the thought never occured to me (maybe the bass was down in level a bit but detail seemed fine at low volume) and I am sure the 1.7 must be better than the 1.6 in regard to detail.
