Confused...not satisfy with my system :

I don't think I be able to do some extreme changes like bypass the Crossover and add a external crossover... or make any physical change to the speakers itself ,I trust SF and far as i understand the crossover in the Extrema is well design .
I just read in the forum that the MV60 is not recommeneded for hard speakers.
The feeling I get from the 557 (or maybe it's the PRE ...)
that it's not that romantic sound ,not sure the AMP not have sufficient power it just "not it".

The cable speaker I use is Audioquest, don't remember the specific model but I checked with SF before and the recommendation I got that Audioquest one of the Not flexable cable should be good enough.
I'm not that big fan of Cable ,I believe it should be good but really don't think it must be pricey.

Right now I don't have a CD , I sold the Arcam (and I regret),the Alpha9 is awesome cd,
In general I a big fan of the Arcam sound - in particular the old Alpha ones....funny that Arcam i had is 10 times cheaper than amplification im having now , But really feel It's not it.
I tried meridian 508 , 506, sorry but I something in Meiridan are not my taste ... It's "Fat" sound and very detailed but NOT exciting with warm and sweetness .

Sorry buddy but for my ears power cable is not making any difference,

So frustrated:(...I spent a lot if money and time but feel like I can't enjoy my Stereo system.
I thought about starting from scratch...
but it such wasted of money,I thought maybe changing the PRE ,people always telling me the things that bothers me is in the PRE.

If you don't have a CD player now, what source are you comparing against your old system with Arcam CD player?

FWIW, Meridian is famous for its DAC and CD player, not for the amps. I used to own G68XXV and it was fabulous.

It takes a lot of time and effort to get the system to the level one can enjoy. All the components in the chain will affect the sound. You should really change one component at a time, otherwise you won't know what positive effects came from which component.

Is there a reason you didn't get a CD player? To me it looks rather obvious that what you are missing is a good CD player, not a replacement amp.

I have a client who has the Sonus Faber EXTREMA and I set him up with a DeHavilland UltraVerve Preamp and NuFORCE Ref 9v2 monobloc and he is in heaven.

Avico,
I didn't want to mention this and confuse things further but I am one of those "Pre people", that is in my opinion nothing influences a stereo's sound like a preamp. I can still remember my first tubed preamp years ago, an Air Tight ATC-1, it was a revelation, the sound just opened up, becoming warmer and more detailed at the same time. I've since moved on but I will always used a tubed preamp. Perhaps you can borrow one from a friend/dealer to try in your system? You may be amazed and find the rest of your gear is suddenly satisfying.

I agree with Jond.I feel a preamp is a "must" and it should always be "tubed"
