Dynaudio C4 speaker equipment matching


My first post, looking for advise.

My system includes:

Plinius CD101 CDP
Plinius Tautoro Pre Amp
Two Plinius SA-103's running in bridged mono configuration
Nordost Frey interconects(2m) and speaker cables(4m) Nordost Thor power conditioner and Brahma power cords (2m) attached to all equipment
Finite Element Signiture racks
Ceraballs and Cerabases
Dynaudio C4 speakers on spikes

The room is untreated and large, 12ft ceilings, 23ft long and 28ft wide. Speakers are 4ft from the wall rear wall. Listening is normally at moderate levels.

I listen to rock, male and female voices, acoustic guitar, a little RAP and techno. Broad taste.

I have a very large sound stage, which I love, though sound is to forward for my liking.

I am looking for more dynamic's, increased depth in the sound stage and greater bass control. I was thinking of starting with the CDP, was thinking of WADIA 861SE, Esoteric SA60/UX-01 or similar and was also thinking of going to Nordost Valhalla cables, though the pair I tried did not make a significant difference, to my suprise.

I was told that changing to a copper power cord on my preamp might help with depth of sound stage. Would appreciate any advise as to the weak links in my system and upgrade opportunities, biggest impact first. I want to keep the SA-103's amps.

On thing I noticed when I demoed the C2's in my home is when I had them toed in they did sound a little too forward compared to my C1's. Then Mick from Dynaudio suggested not toeing them in at all because the the wide dispersion tweeters. That helped the forwardness and widened the sound stage.

That being said I will admit my room setup is not a good match for the C2's. My room is very strange 14' X 26' but the system is on the long wall (and has to be). For me I also had to move them to 2' from the rear wall and that's when I really lost the depth.

I know I didn't answer your question about the equipment but try not toeing them in and see if that helps.
Xtil6, thanks for the advise. I do have toe in on the C4's, I will try some diferent placement scenario's, I am no expert in speaker positioning.
Without question, the first thing I would do is address treating your room. Room treatments gave me the biggest bang for the buck when I had my C4's. I found GIK Acoustics to be very helpful and cost effective. You could probably treat your room for $1,000 or less.

The second thing I would do is replace your preamp with a tubed preamp... as you can tailor the sound of your system by tube rolling.

The third thing I would change is your CDP.

I don't think changing a powercord will transform your system.

Nice amps by the way.
Room treatment a must!!!!..Im not a fan of Plinius with the C4s..Pass labs is the ticket if your set on solid state IMO(x250.5 or better x350.5)..I would also dump the Nordost cables,I ran them with my C4s for about a week .Hated them..A nice tube preamp will help some,I dont totally agree with the tube rolling theory as far as a drastic system change..I find a great tube pre will not drastically change its character by simply changing tubes(if it did it would be long gone from my system)...The room treatment will set you in the right direction
Dear Jon47: My friend Alan has the C4 running through the JC1 monoblocks and the quality performance is just great.

Regards and enjoy the music.
