    Default SDA 1C's - Will I like them?

    Hang on...this could be wordy!
    I have been following you guys for awhile now. Have done a ton of research (this site and many others). Listening sessions for the speakers I have been considering aren't really possible anyway, so I have to rely on places such as this. My budget is limited to under $1000. I think I have drawn to the conclusion that my next speaker is going to be the 1C's. I have always liked a wide soundstage, in fact, always thought most systems lacked in it - even ones at the old Stereophile Shows with jaw-dropping budgets. I have never heard SDA's, but sounds like they're up my alley. I have been keeping an eye out and have found a pair in pretty good shape in my state (though haven't seen them yet) and a halfway decent price, but......will they work for me?

    - My room size: 14x20
    - Powering them (for now): B&K 125.7 S2 amp (bi-amp?), Cary SLP30 tube Pre, Pioneer Elite PD-65, Audioquest GR8 speaker cables
    - I listen to Rock/Metal/Pop mostly (concerned there might be too much processing in the engineering?)
    - I mainly listen at low to moderate volumes
    - I currently have Boston Acoustics previous flagship VRM-90 (picked them out mainly for HT)
    - I've also owned Legacy Signature II's (definitely better than the BA's, but wife didn't like looks for new home at the time....now that doesn't matter - going into man cave)

    PS: They are missing the stock IC cord, but sounds like I can purchase a better one from Ben anyway.

    Opinions welcome...

    I had never heard and SDA speakers until I purchased a set of completely modified SDA 1C's for $625. That was without any reservations the best money I've ever spent on audio. If you like wide soundstage then these are your speakers. The room size is perfect for them. You will need the IC cable to get the full wide soundstage though. Listening to them without it will seriously cripple the experience. I think your current setup will work nicely with them provided it's a common ground amp. The 1C's love power and with a ss amp with big power they really come alive. I use a Carver TFM-45 which is rated at about 375 wpc. I listen at low to moderate levels and am blown away daily by how great it sounds. I say if you can get the 1C's for a reasonable price go for it. Enjoy.

    Go for it, make sure your amp is common ground, you can't bi-wire, you won;t need a sub if you set the 1C's up correctly, they need high quality amplification not quantity. If you have high quality and quantity, great, but don;t skimp on the high quality. I run a 30 wpc single ended pure class A amp. Haven't run out of reserves yet.

    I'd also say replace the stock sl2000 tweeter with the RD0194-1 silk dome replacements, as they are sooooooooooooooo much better sounding.

    Did I say go for it!!!

    Very glad to hear that my room might be perfect for these.
    I would not use them without the IC, though the owner said he was just using speaker wire to connect them....don't know if that's possible with these though?
    Guess I need to do the compression test (reminds me of buying an old muscle car) by pushing in the passive radiator, and should have a 4-5 second delay, at least, correct?

    Question: If I push on the passive radiator, and the drivers DO come back almost instantly (meaning there is a leak) do I buy them, or run away???

    Here is the specs on my amp:

    Damping Factor (50 Hz) 180 / 180
    Frequency Response 5 Hz - 45 kHz
    Slew Rate 14 V / μsec
    Input Sensitivity RCA Unbalanced 1.0 Volt
    Input Sensitivity XLR Balanced 2.0 Volts | Pin 1 = Gnd, Pin 2 = In +, Pin 3 = In -

    With that budget you could do big things with some SDA-1C speakers.

    You really think the 1C's perform well with that much seperation, and shooting shallow - that could put 9'-10' between 'em? I'm sure you know from experience, it's just a different combo than I'm used to.
    Would it mess the left soundstage up since my ceiling is cathedral and goes from 8' to 9.5' in height? Might have to try it both ways I guess? Though the first way would be more WAF...and she is pretty important in my life (in case she ever accesses this website :D).

    BTW, I do plan to upgrade these at some point. That's one of the attractive things about these. Pretty strange when you want to upgrade something before you have even heard it? You guys are good salesman...and I'm in sales. I know your just speaking from the heart...errr, I mean the ears. And I have grown to trust your ears.

    Who said anything about more separation, you still want to keep them about 6 feet apart. Do the math and it comes out to requiring a 15 foot wall at the minimum, hence the long wall in your case. Now, the ceiling factor may change everything, but I can't say as I've never had to deal with that issue.

    You might want to look for something with a bit more current. Mine is 160 amps, peak to peak.

    How do I know if my amp is a common ground? I've looked through the whole owner's manual...which I didn't find anything?
    It has one plug!

    I tried to look at your history to find out what you have exactly, but this website makes it so hard, I gave up, so what do you have?

    I have been seriously considering a tube amp for my future, and know some have liked it on their SDA's, but what to get (tube or SS) that would be an even trade for what mine would sell for (bluebook on A'gon is $1160)? I'm cool with used, and don't need multi-channel anymore.

    Never toe them in. But I guess if you have absolutely no other option. Toe in ruins the SDA properties.
