Magnepan 1.7

>It also seemed to me that they were eating up the Mcintosh mc275 amps.

The speakers were woefully underpowered. Maggies will play loud, but they're only 83 dB efficient. They also rarely sound their best in a dealer showroom, since as I'm sure you know having owned the Apogees and Eminents, they require careful placement and have different acoustical requirements than dynamic speakers. That's not to say that they're the speaker for you -- I haven't heard them yet myself -- but to point out that the people who have praised their bang for the buck probably aren't lying! Though I have heard some complaints from people who say they don't like them as much as the 1.6's.

Energizer:
One big reason you may like older Maggies is that sometime in the '90s they began shipping with the Mylar toward the listener.

A couple years ago I sold my factory rebuilt MG-1s and bought some 1.6s which long term were irritating...until I simply rotated them in place.
I now listen to the Pole Piece side, just like the old ones.

I'm starting down a path of further adjustments, too. I just make new jumpers out of #6 copper wire to replace the Chrome Plated Steel the panels ship with. Eventually more mods are on tap and even the jumpers and fuse will go away when I go into the crossover mods.

I've had my 1.7s for nearly 3 months and have several hundred hours on them. I've hooked them up to various amplifiers, including a Parasound JC-1/JC-2 setup and an Audio Research VSi60 and find them extremely musical, particularly with the VSi60, which drives them perfectly to very loud levels without difficulty. I've experimented with tweeter in/tweeter out, reversing the speakers (so the back of the speaker faces the listening area) and with 1 and 2 ohm resistors and find that in my room they sound best with 1 ohm resistors and tweeters in. I much prefer them to the B&W 802Ds, Usher 718s, KEF 201/2s and Apogee Duetta IIs I've used in the same listening area over the past several years and would not hesitate to recommend them to anyone looking at speakers selling for less than $10k. I was concerned the Audio Research integrated amp would not have enough power, but it matches up beautifully and has more than enough power. I'm listening to the SACD of Bigg's performance of Bach's Toccata and Fugue in D minor at a very loud setting as I write this and cannot imagine how it could sound much better.The bass is stunning and I've tried, and turned off, several high-end sub-woofers because they add very little bass and some dissonance. The speakers and the integrated amp are both highly recommended and make great combination.

The reason, at least a POSSIBLE reason for your preference is that sometime back in the '90s, and for no apparent reason, they began shipping with the mylar side facing the listener. This is a 180' flip from prior practice.

I flipped my panels around and now listen the 'old way' and won't go back.

Just a thought...........

and a possible experiment for all you new 1.7 owners.

CHarles : I have the same reaction after three months. They do thrilling things. I play a lot of organ music (Chapuis Bach set and although they tilted to the upper mid range thge force of the bass is compelling. I have found the german Harmonia Mundi recordings of Bach works overwhelming in the way the clarity and sweetness chorus is revealed. I owned a 150 lb. a piece hybrid electrostatric and thought I could nev er replace them as they failed. These are infinitly better even with a vintage solid state amp.
