    1.2tl's are my favorites mostly because it's the only pair of sda's I currently own. Had the 2.3s non tl and a pair of the crs's. They were excellent sounding speakers but to me there's nothing like the big guys.

    I own both CRS+ and 2B SDA speakers. My favorite is the 2Bs. The TL upgrade and new inductors makes them sound amazing. The 2Bs are all I listen to. The CRS+ are packed away in the closet in case I ever need them.

    Thanks for the offer but it's better to have them an not need them than to need them an not have them. Who knows? I might want to use them in a home theater setup someday. I think it would be a good match to have my 2Bs in the front and the CRS+ in the rear. I don't have any plans for that right now but...

    My 2ATLs amaze me every time I listen, I also have the 87 CRS+s which have also been Upgraded and TL'd. They don't go as low as the 2As, but none-the-less are equally impressive. I'd love a pair of SRSs some day, but my room is too small. Either the 2As or CRSs can fill the room to deafening levels. boston1450, the invite is always open, if your hauling in this direction.

    The room size has been key for me. Having the 1.2TLs, they shine when you juice them and my room is frankly too small to fully let them breath. The 1C has been awesome as have the 2Bs. I recently picked up both RTA11 Monitors and the 11ts and though they are not SDA, sound great too in an average sized room.

    my favorite pair are the ones that best fit the room they are in. I have had many different models and I cannot stress room size. Yes, they will sound fine even if they are technically too big for the room but properly set up, they will amaze you.

    With that said, my fathers 1.2TL's are my favorite. He has room to let them breath. I just got married and the wife has been amazing with letting me bring two pairs of SDA's into the marriage, what a woman! She even gave me the OK to dedicate the largest upstairs bedroom for an "entertainment" room where my 1C's will be going. She also let me park my 2A's downstairs in the family room. The room is too small for them but they still sound great.

    I have found that my CRS+ have a much larger soundstage image than my 1Cs in the same room. I believe that this is due to the mid-driver horizontal distance being larger on the CRS+ than the touching side by side placement of the 1Cs. I have heard the same imaging characteristics on SRS 2s in similar sized room, they simply image better. I am also continually pleased at the amount and quality of bass response out of the rear radiators on my CRS+. There is something about the way they load bass into the solid wall behind them. They really respond to placement adjustments better than the 1Cs too.

    I am wondering which SDA I would like. I currently do not have any Polks but always on the lookout at GW and CL.
    My listening room is a small 10x10 and will be for the foreseeable future. As much as I would like SDA speakers I don't think they would work to good in a near field environment .

    Any ideas, suggestions or comments?

    CRS+s could work, but you're correct, that room won't let them breath at all. A pair of Monitor 7s would be better suited, and will put you on the road to classic Polks.

    Agree with westmassguy. I've got my CRS+'s in a 12x12 room, and that's very tight. I can't imagine being happy dealing with taking 2 feet away from the length and width.
    Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

    Yes I was thinking Monitor 7. Less power hungry so easier to amp. Also my room is actually a bit bigger. I didn't count the space my desk takes up, so it is more like 10x12.

    I think the 7s with proper stands will be perfect. The CRSs would work as I said, but you're doing them an injustice in a cramped space.

    Hunting for/lusting after CRS+ to dip my toe in the SDA water. There is the complicating factor that my new amp is not common-grounded

    What new amp isn't common ground....? Tubes, mono blocks...?

    That was a question I posted yesterday as I was looking a picking up a pr of SDA 3.1TL's which I did pick up today, they Aldo came with the manual and cable pin/blade upon reading the manual Polk says that most Recievers and higher end amps are common ground..

    NO monoblocs are common-ground, although a pair of them can SOMETIMES be made common-ground by installing a jumper wire between the negative terminals, one on each amp.

    ALL bridged/balanced amplifiers are NOT common-ground. This includes some monoblocs, and some 2-channel, and multi-channel amps. A common-ground stereo amplifier such as an Adcom GFA555, when bridged, becomes a NON-common-ground amp. Do not, EVER, try to install a jumper wire between the negative terminals of a pair of bridged/balanced amps.

    SOME stereo amplifiers have an inverted channel, such as early-production Carver M1.0, and every version of the Carver M500/500T. Any amp with inverted channels cannot be common-ground.

    SOME "Dual-Mono" amps are separated on the positive side, but are common-ground on the negative side where it matters for Polk SDA use. Other "Dual-Mono" amps, like Aragon 8000 series, or some newer Adcoms have resistors built into the negative side that produce excess resistance between the negative terminals, leading to horrible sound quality, or outright shutdown of the amp--or even amp and speaker damage. If the resistors are bypassed with a jumper wire, sound quality cleans-up.

    DO NOT rely on assumptions or the advice that "most of them are OK".

    To quote from the Polk SDA SRS Instruction manual..
    " All Major brands of receivers are common grounded and are virtually all integrated and separate amplifiers are common grounded."
    "Very Few amplifiers are not common grounded and are usually marked with some warning near the output terminals"
