SDA2b's

BRBest

I am a very old (66-year-old) newbie. Please forgive any previously asked or stupid questions. I have just acquired a very nice set of SDA2b's and don't have any idea of what amplifier brands are out there that are common ground. Any known amp suggestions would truly be appreciated!
I am going to run these off of a Pioneer SC-LX704 AVR for now, as Pioneer has responded with the following: "Regarding your product inquiry, the SC-LX704 is a known model to be a common ground unit system, and due to that it should shake hands or communicate with the set of Polk SDA2b speakers you have setup".
I am not sure if the wattage from this AVR unit is enough to drive these speakers, or if I need an amplifier.
All thoughts and insight will be appreciated!

Parasound, Sunfire, Rotel, B&K, early Adcom in the 5xx series. If the Amp is dual mono it can be a problem. Any monobloc is a problem. Some Amps use an inverted channel and those are problematic, some early Carvers come to mind, that being said the Carver TFM series is ok.

Thank you Pitdogg2, I do appreciate the response. When searching for these brands, is there a way to tell what I am looking at? Because I don't really know what you mean by monobloc or dual mono. I have never even bought an amp before in my life. This is all for my home theater system, and I am just venturing into this arena.

Monoblocs are seperate amps for each channel in other words one channel amps that take two to make stereo. here is an example

Dual mono amps are two seperate amps in one case Aragon which I own is one. Some dual mono amps are in fact common ground so you must ask questions or if you're able to, test the speaker ouputs to see the reading of the ohm factor.

If you stick with the first 5 you'll be okay.

Perfect Sir! Thank you!

I buy used most of the time. The Parasound HCA 1500 plays well with my 2Bs.
