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.

From a logistics perspective (room treatments in parallel) I borrowed some MIT MA interconnects and Cardas Golden Reference speaker cables (only had one Golden Reference interconnect in stock to lend me) After many hours of changing and listening, the combination that worked best was the Cardas Golden Reference speaker cables and MIT interconnects. WOW, what a difference! Much better control and realism. The harshness of the Nordost is gone (so is some of the air arounf voices and intruments unfortunately) I will borrow another Cardas interconnect and some MA speaker cables and continue listening. Will let you know the outcome...but going in the right direction now. I have been searching for decent looking and effective room treatments, in parallel...still looking...suggestions most welcome! Also, placed cerabases under the speakers...made a noticable improvement to the base control. Also moved the speakers out from the wall another foot and spent some time on placement...I had too much toe in and speakers a little to close together...depth of soundstage is improving.
I would suggest you try the MIT products together for best results, with the best IC at the source and so on down the chain. The speaker cables from MIT are phenomenal, but will only pass on what get's to them. You might want to try the Oracle DOT 2 cables, namely the V1.2 series...they were the former top of the line and may give you what your looking for at a lower price point:O) Have you contacted Joe Abrams at Equus Audio? He is THEE MIT guy to talk with and also offers new MIT product at 50% off retail (not the MA however). I have heard that the MA series is different sounding from previous offerings and may not be as sublimely musical as the Oracle stuff.
Well after a full weekend of testing high end MIT and Cardas cables, I finally found what sounds best to me in my room with my music tastes and equipemt. Best results for me were achieved with Golden Presence from CD to Pre (XLR) Golden Reference from Pre to Amps (XLR) and Golden Reference spreaker cables. I can listen to this combination for hours on end, without fatigue. Also tried Nordost Valhalla and all sorts of combinations.

Now for treatments!
