Till yesterday afternoon, I was really wondering if I needed an amp change to better the sound of the PMC's. Everything was there except a slight loss of clarity. Like the sound was a bit muddy. So decided to check the polarity of the drivers, and dismantled all the drivers yesterday. And luckily found that I had mounted the left tweeter out of phase. After correcting it, iam finally in audio bliss. The inversion of the tweeter has removed the 2 complaints I had left with the speakers :
1. Vocals are now exactly as they should be . I found them to be in the background and not in the front before. This has been corrected now.
2. The boxiness to the sound that I mentioned in the past is completely gone.
Now I have absolutely no complaints with how it all sounds . And till yesterday I was not certain if I should sell the concept 40's. But now I can say, that the PMC's are in a different league and it is now a no contest between these two. I've never heard sound this good. And IAM sure that upgrading the amp will make things better. But as we speak , the parasound is at 10 o'clock position, and not breaking a sweat as it drives the PMC's clean and loud. I've tested some audiophile HD tracks in my room, and it goes down to 15 Hz super loud and clean. The loudest I have gone is 12 o'clock and it gets disco loud, and absolutely no distortion or muddiness. Everything stays clear, focused and locked in place. The parasound is absolutely not short of power for the time being. A better and more expensive amp will certainly better things, but Iam afraid the law of diminishing returns is already stepping in. In my humble opinion the same money spent on a better good quality source will give me better results. IAM thinking of either the Linn majik DS (95%) or Naim nd5xs (5%) or continue to use the wxc-50 as a digital renderer and add an external dac like schiit yggdrassil and Dirac live ddrc for room correction. I think it would cost less to implement this and will give me better sonic gains.
Secondly, when I dismantled all the drivers yesterday, I noticed that the drivers are mounted directly on the cabinet without any isolation gaskets. Is it normal for PMC speakers . And will I get better sound by adding a rubber gasket for better insulating the drivers.
Thirdly, iam presently using the supplied spikes on my hard tiled flooring. Iam not worried about flooring damage. But will the sound get better if I use rubber caps on the spikes.
Thanks
