Maggie 1.7i's lack detail. Ideas?


Hi,
In about 1979 I had a roommate who had a pair of Magnapan's, an amp, pre-amp (at least one of which was NAD, and a fairly high quality turntable.  I was shocked and amazed about the feeling the singers were present in the room with me.   The accuracy and detail of the sound.

Fast forward 40 years and I purchase a barely used 1.7is.   I have a new Marantz NR1200.  A 15 yo BK EX-440 Sonata (350WPC @ 4 ohms), and optical bit stream out Sony DVD player.  I use optical cable between the DVD player and NR1200.   I have fairly high quality cables between the pre-out of the NR1200 and the EX-440.  I have somewhat high gauge copper stranded cable, about 6', between the EX-440 and the speakers.

The sound is not bad but very much lacking the detail and immediacy I remember in the highs and mid-range.  A great disappointment. My question is what the most likely culprit?

Some possibilities:
1. My hearing has declined.
2. I've a romanticized memory of the sound quality.
3. What I was hearing was the mushrooms.
4. The speakers my roommate had were a bit wider.  Maybe more like the 3.7s.  Maybe 40 year old 3.7s are just that much better than current 1.7is.
5. Stranded wire cables.
6. Turntable that much better than CD.
7. ????

Stereo spread is over rated for I think it discombobulates the sound to some degree.  Try listening with tweeters 4 feet apart and tow slightly inside of straight toward you.  The purpose is to get the ambient field focused.  You get richer timbre and hall sound and less need for a sweet spot;  more like live music at 10 to 14 feet away.  One holistic sound.

@jros , probably a combination of all those factors especially the mushrooms.

The speakers should be three feet off the wall and the wall behind them needs to be completely deadened. I would use acoustic tile. 

Maggies do best with powerful class A amps. 200 watts/ channel RMS into 4 ohms is the real minimum. The 3.7i's are a much better speaker and one of the best values in a high performance speaker out there. For the best bass below 100 Hz you still need a subwoofer but otherwise they are brilliant. It is the real ribbon tweeter that makes the difference. It is arguably the best tweeter made.  It you want detail almost at the level of and ESL the 3.7i is the way to go.

I have a B&K EX-442 Sonata (it's "442", not "440", btw) running from a Parasound P5 preamp into a pair of Maggie MMGs (precursor to the LRS).  My system sounds outstanding (I run CDs through either a Denon DVD-2900 or OPPO BDP-95) both connected via RCAs.

I can tell you that as long as the 442 is functioning as it should, your issue is not with it (or likely with the Maggies either, for that matter).  While more is better, that amp should have plenty of good, clean power and high current for those speakers, IMO.

The first thing you should do is upgrade the fuse and jumper with a silver fuse and jumper. I did this to my 1.7i's and it made a very noticeable difference. And it will cost you less than $100. Start there.
