Proac owners......advice please


I am runinng an all solid state Electrocompaniet system; DMB 120, 4.7 Pre & EMC MKII. I recently purchased a pair of Proac 2.5's.

I will tell you that the speakers now have about fifty hours on them. Cabling is all Nordost Red Dawn at this time. The room size is approx 17'x 24', with a 12' cathedral ceiling. The good; we have big sound stage, we have wonderful mid range with very good rhythm & pace. Please play the Dixie Chicks again!
The not so good; The bass gets dominant from time to time. I won't say that it's boomy; it's like blowing a low note through an empty paper towel holder. The highs or vocals during the playback are just not on the same level when this happens, & my ear goes straight to the bass. I might add that the vocals could be a little smoother. Maybe my room is the problem? Maybe the speakers need more break-in time?
Before I consider room treatments & the likem,has anyone experienced a similar situation or could you suggest a different cabling option? I am fairly new at high end passion...so I really need someone that is famliar with these speakers or has owned solid state with the Proac's- what have you done to get the best possible sound out of them?
I know many of many of you state that Proac's sound is the best with tubes --and ARC is also a great match. I did try an ARC LS 16 pre this week with my amp, but the match wasn't that great. I do think that I would like to stay with solid state for a while, but I am hoping that you can make suggestions about how to achieve a better sound quality with my current components or alternatives that will enhance it. Thanks!

These are all good responses. You may find that serious room treatment is what you need. ASC products are not cheap, but they were worth every nickel to me and my room boom problem. There are also some DIY knockoffs if you're inclined that way. I also suggest upgrading the speaker stand. Proac uses that wide plinth and meager spikes. Check out the thread on Sistrum platforms. I also looked into Mana Acoustics, which has a reputation for tightening loose bass.
This is great information, but a little disappointing. I'm shopping for speakers and really like the Proac 2.5, but am now concerned about the booming bass issue. It's so hard to get an accurate evaluation in the dealers demo room since everything is optimized and nothing like an environment *most* of us live in. Should I be concerned about the bass issue with the 2.5? Will the 2.5s require painstaking amp, pre and cable matching? I'm not looking for a fulltime tweaking job, just some honest music.
Best,

2.5's are very nice speakers, but do have plummy bass, which is not the bass you describe. That said, something may be amplifiying that quality. If not a break in situation, room treatmnet sounds best, although I would never reach a conclusion on a ProAc 2.5 using Nordost Red Dawn. Don't give up on the speaker.
Rg I tried to mate the Ls 16 with the Electro amp. I was very curious as to how it would sound. I really did not add much but, took away a lot. I am sure that mated with the AR 100.2 would be ideal.
Drubin...thanks for the response & yes the spikes are in. I will heed your advice concerning chasing cables but, I am in need of a balanced pair of interconnects from the Electo EMC cdp player to pre. I am running single ended now & balanced makes a big difference (for the better) with these components.
