Wow, I didn't expect the thread to get this big! I just read it all in one go lol!
Okay the PMC IB2's were being powered from a Bryston 4B SST. The Desk was an SSL AWS 900 and the CD player, as said, was a Alesis thing which looked a lot like an ADAT!
There was a room resonance in the low mid range, I think around 200-350Hz. It made the sound pretty muddled around here but the same was evident in the IB2's as well so it was a fair demo.
In my opinion the MEG's were indeed a better monitor than the IB2's and Bryston combo. On switching from the MEG's to the IB2's and back it was quite evident that the MEG's had more detail in the midrange. Despite the IB2's being louder for the same level setting on the desk, they sounded more shut in.
It's surprising I say this really because I am a great fan of PMC and Bryston. I have heard a fair number of systems and until the MEG's, I had not ever thought of them as sounding 'compressed'ââ'¬Â¦ but in comparison, they do. I didn't really understand how Thorsten could say speakers sounded 'compressed' because I have not heard it before. It's not compression like an electronic compressor in a studio. Its like the MEG's had a bigger pair of lungs on them. They had more scale, consistency in tracking instruments and were simply more involving.
In the large room, the AML1's did sound quite smallââ'¬Â¦ and they are! But I do in fact rate them as sounding more accurate and more like the MEG's than the IB2's.
The accuracy of the MEG's really stood out when I played my own recording's / performance's that I mixed in my home studio on AML1's where I have extensive room treatment and some digital room correction as well.
Now you would think that as I made the music on a pair of PMC speakers that are closely related in design to the IB2's that the music would sound more as intended on the IB2's than on the MEG's, but it didn't. The recordings came across much closer to what I heard in my studio on the MEG's than on the IB2's!! The IB2's sounded like they had a more tizzy, thin trebley reproduction. They missed some of the guts of the MEG's. I think for one, this shows that my system is pretty damn accurate

but also that the MEG's are able to be more accurate than the IB2's even in a non-treated room.
I came away from this demo very impressed with the MEG's ability to resolve detail and reproduce large dynamic range / scale. I also feel very happy with my own system. Although the AML1's sounded 'little' in the demo room, in a small room like mine, they actually sound very close to the MEG's. They have a good balance and only miss the very last word in detail and dynamics. I Think while the soundstage on the MEG's is large, the imaging on the PMC's is better.
Paul, I find it surprising you say speakers with a flat response sound dull too you. You own IB2's, which in comparison to many speakers, are flat, but also the MEG's which are flatter still, sounded far more involving and alive than the IB2. This is probably more due to dynamics than the response though.
The cardioid response of the MEG's was very impressive. If you walked behind the speakers the entire music got quieter, including the bass! It was like shutting a door between you and them. This would no doubt do wonders for room interaction from the rear wall and also stop your neighbours complaining as much!
On a final note, I liked the MEG's a lot. I think with a valve pre-amp they would sound perfect for both use in a home and studio. If my room were bigger I would be saving up for a pair, but as it is, my AML1's do the job nearly as well for my small space. The PMC IB2's are indeed great speakers but I find their response slightly off in the high frequency. No speaker I have heard has sounded as dynamic and resolving as the MEG's so its no insult to say they IB2's didn't do as well here.
P.S. Titian, I would be happy to demo the MEG's with you, I only hope KMR wont think its too cheeky to keep listening too them when I have no intention of buying them.
