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.

Thankyou all for your invaluable comments. I will take the time to read your suggestions. I have approx 60-80 hours run time on the system to date, more burn in time seems to be required. A combination of room treatment, speaker positioning, cables, AC circuit improvements are the consistant message. Good news for me is that I should not jump too quickly and start changing out components.

The Pass X350.5 Amp would have been a great choice, though significantly more expensive than the Plinius Amps.
Jon47, I have a Plinius Tautoro pre-amp and plinius sb301. This is a great combo. Please do not change pre-amp. I tried several tube pre-amps (Antique Sound Labs Arc Ref 3 and CJ) none of them was giving me dynamics, air and depths of soundstage as Tautoro does. Also I had a Plinius cd-101 player. It was ok but I was missing the space and air around instruments and sound was a laid back, even so very musical. I changed it to esoteric x-03se. Much better player. Air, dynamics and musicality in spades. But you should start from room treatments first as other suggesting. Cables may help but the effect may be minor.
Dear Pdrehar,

Thanks for you comments.

I have followed your thread regarding your system with great interest, as we had the same speakers and amp. Shame that you did not get a chance to go with 2 x SA102's in bridged mono vs. one in stereo, the improvement was startling in my system when I added the second amp.

Interestingly, I also auditioned the Harbeth M40.1's and Spendor SP100R's, as well as a long list of other brands prior to the decision to go with the C4's. I completely understand the appeal of the Harbeth M40.1's...very musical indeed and easy to drive well.
