My New Magnepan 1.7i's sound dull and lifeless on the top end...why?

-PrimaLuna EVO 400 Monos

WOW those monos are some power pack amplifiers, 
Built in same factor as Cayin, Spark Audio, High quality, 
Very surprised you are not getting higher fidelity in all ranges..
hummmm,. 
I was close to buying the LRS, until my tech geek stepped in to cancel the project, 
Said the LRS has 4 phms impedence, 86 db, not friendly to the Defy7,,**ok for string quartet**, well the purpose was for big full orchestra symphony,,
Tech: *Not going to happen,**.

Not sure if what he is hinting at has anything to do with your issues of faulty highs, no sparkle, shimmerings, dynamics in upper fq's..
Sorry to hear of  this venture into Magnepan. 

There  is a big faithful magnepan group here,,maybe one these Magnepan-ians
can *chime* in here and give us some  solutions to this roll off issues.
Good Luck

~~~~~~~~~~~~~~~~~~~

You are NOT offering anything substantive to help resolve his issues...


You should, we all should re-read exactly what the OP post is saying, He never siad *8I am not sure if I have them puled in correctly**
He states,, why is the highs sounding rather crappy?**

I think he deserves a solid truthful answer from The Magnepanian Club
as to why the magnepan’s are not performing up to the reputation.
Do we have a case here of hype and snakeoil..or what ..........
You tell me,,I was just days from orderinga pair....
My tech screamed at me

**NO*
Just in the nick of time....

Seems to me, this type of speaker requires a  specific amplifier in order to achieve maximum performance..
Or a I wrong?

Maggies like high power

~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now we are getting somewhere, which may lead us to the resolution of the OP,,,wait a minute,
Nayls02 has a massive SS amplifier,, and still he can not get the Magnepans to perform as high fidelity speakers...
......

Sure glad my tech geek screamed at me..
***NO***
wow, would have been yet another speaker project disaster.
The Voxativ Project set me back $900.
Good Luck to Nayls02
I’m outta here

If damaged it's unusual that both speakers would have the same fault.

Not a clue as to what the "add-ons" mentioned by the OP are, but suggest hooking them up stock (nasty jumper plate and all).

I responded to another Maggie owner here with similar complaints and the HF problem was resolved with proper hookup (poor electrical contact was the culprit I think, but too lazy to look back through my posts).

I aint buying in.
No evidence his hookups are faulty.

 amp, or a modern parasound amp.  Needs an amp that can deliver fast settling amperage


~~~~~~~~~~~~~~~~~~~~~
This is what my tech was getting at. 
~~Requires high(er) current~~ than what the Defy7 can deliver = Not a  match made in heaven.
Is what he was trying to express.
He suggests , sure for string quartet, the Magnepan + Defy marraige would be excellent..
Well thats not what was the intention. The magnepan was for voicing full slam orchestra, in super high definition rock solid bass, rich detailed perfect voiced midrange, and the most glorious highs ever heard by the human ear..
Is what I had set my hopes on for the Defy7.

Magnepan is quite magical, we all know this based on countless testimonials. 
The caveat is a  amplification current that can deliver the goods.
Lets stay focused. 

As I  now recall was often mentioned when discussing panels wayyy back in my Topic, ShootOut at the OK Corral...
How could i foget,,,which is why i never reconsidered going anything **panel*

Are you sure there is not some snakeoil selling going  here?
