Looking for a new amp setup for my 3.1TLs and need assistance

I found some 3.1TLs last summer and they have been awesome. The guy I purchased them from was bi-amping them with a Pioneer VSX-80TXV that he threw in for free. This is my first HiFi setup, so I figured bi-amping was the way to go per the SRS instructions recommending it. I ended up piecing together the following system:
Marantz SR6001 AVR powering high frequencies
Arcam P85 amplifier powering low frequencies
As I've been continuing to learn more, I've come to understand that bi-amping is not beneficial in my current set up and that I'd be better off getting rid of bi-amping and powering with a beefier amp. I thought I found a great option with a Fosgate Audionics 4125 (220 WPC x 2 in bridged mode), but it turns out that it is not designed to handle such low impedance as seen with the Polks (had to reach out to the guy who built them to be sure).
So now I am back to looking for a better amp setup.
I have found some used Marantz MA-700 monoblock amps for sale, locally.
My question for the group is whether I could use these to power each 3.1TL? Would I be able to just feed input for left channel into amp powering left speaker and same for the right channel? Or would they have to be bridged (BTL-ready, whatever that means)?
Happy to clarify anything,
Cheers!

You will need a dreadnought or AI-1 cable to use monoblocs or non-common ground amplifiers. Forget anything bridged, they do not like less than 8ohms and you also raise the noise floor of the amp. Look for a good Parasound amp.

The more I read, the more out of my depth I feel lol. I feel I should continue to search for a common ground amp that can offer more than my current setup just to build a bit of confidence before pursuing a dreadnought setupYou will need a dreadnought or AI-1 cable to use monoblocs or non-common ground amplifiers.

Hello Mr. President. Can you advise if a PS Audio Delta 200 would be appropriate in this setting? I can't find anywhere whether it is a common ground amp or not. -
Best bet is to call PS Audio about that.Political Correctness'.........defined

A Phase Linear 700 that’s been WOPL upgraded would make them sing.
It originally was a 360w per channel amp but once WOPL’d they now put out right at 500w per. -
Of course you should check with PS Audio, however the schematic seems to indicate that the negative speaker terminal is connected to ground:
Point A is the positive terminal and the terminal below is the grounded negative terminal. -

I bought a used Parasound Halo A23+ a few years ago. Excellent amp. Highly recommended. -

Cheers, thanks for interpreting that for a newbie.
