Hey Kew would these speaker be in your top five? DCM killer? I’d like to see your top 10 one day. I know the Cantons would be at least in your top 3 position. Tempting at that price of 160/180 prices. Did the center with midrange ever go on sale? If they did how low were they?
For value, I think the DCM is easily the best speaker I have ever encountered. I mean the Pioneer BS-22 went for about the same price (when on sale) and was the best deal for that price for a long time, but the DCM clearly blows the Pioneer out of the water! It easily beats the Sony Core and it beats the Philharmonic AA's (Dayton Audio - which has beat several $200-$500 speakers I have compared it to).
If I were in your shoes, I would not get the infinities because they are too close to buying another pair of the DCM's. That is the problem with such a deal it takes a good bit more money to buy something better.
In my hierarchy (IOW, my subjective opinion), you have two options:
1) Save up for the Studio 530's at $300/pr - IMHO, they are not that big of a step up, but I do like them better than the Infinities (especially when HT is part of the package)! Not that big of a step up ... but a different presentation of sound. IMHO, if you will have two pairs of speakers (say, one in LR and one in BR) it is better to have two different (but neither is "wrong") sounds, so I recommend the 530's to fit this objective!
2) Save up for the Canton Chrono SL with the ceramic tweeter (currently $600 is the best price to get you there-I think I got a pair for $500 or less at one point). This is a speaker that gets a decisive step up from the DCM (or Infinity or 530), IMHO.
Over the next month or so, we should be seeing in-depth measurements/reviews from Erin H. on the BMR (which he recently did), the Focal Twin6Be, and the Canton Vento 830.2 which I dropped off at his house early this month. I really feel that the Canton manages to be fair competition among these three speakers. I prefer the BMR and Focal, but given the Canton's price, it should not even belong in the same pack! But my point is you might wait on Erin's review of the Canton Vento before you decide. I should add taht I took a single Chrono Chrono SL to him as well. I only had room for one, but he was okay with a "quick and dirty" measurement of the Chrono to see how it compared to the Vento. I think the only differences are cosmetic and the rounded vs square cabinet, but would like to see measurements to confirm/refute that!
Oh, the center with mid-range does go on sale! Seems like it sits somewhere between $250 and $300. It would be a good sonic match for your DCM's and is an outstanding center design. Obviously it is not a good color match, but I generally go black for my center even if I have white mains because the black disappears under the screen and the white calls attention to itself. I suppose you could make the same argument against Cherry finish, to a lesser extent.
