Bi amping SDA 3.1 speakers?

I've had my SRS 3.1 speakers since I bought them new back in day. I'm looking at some things to spice them up a little (tweeter, crossover mods) . One thing on my mind is bi amping them. I have a Adcom GFA-545 amp 100 watts, I have access to another one. Is there noticeable benefit to bi amping? I thought I would get some opinions before buying a bunch of speaker wire.

    OH you are about to open a can of worms style debate!! :D:D
    (meaning it depends on with whom you talk. Also please remember you need an isolation transformer in your crossfeed cable. I.E. an AI-1 OR a dreadnaught if you're doing upgrades)
    I STRONGLY recommend either having @vr3 do your crossovers or talking to @westmassguy if what Trey charges is a bit steep.
    I have heard biamping to good effect and to no effect myself btw.
    It depends a LOT on the speakers and equipment.

    Seems like a lot of effort to separate two tweeters from the rest of the drivers. If you have an amplifier that can power the speakers as-is...I'm not sure you're really gaining anything but expense and complexity.

    I hear you on a better amp, I'm just trying to use what I have available to improve the sound with as little additional $$ as possible outside of improving the speakers. The additional Adcom amp is a freebie. I have RD0 198 tweeters on the way and installing them is about it it for my tech abilities. Woodworking is my forte, I can build a nice chair to sit and listen to them, that's about it.

    I don't think Bi-Amping the 3.1TL's, with only one tweeter per cabinet, would be very beneficial. Bi-Wiring "might" be a better option.

    Or, get some better quality jumpers on the Binding Posts and a better Amplifier as Jesse has recommended.

    The 3.1's are VERY easy to drive, Bi-Amping would be a waste of time/money IMHO.

    Well strike one on that idea. I'm trying figure out best bang for the buck, so let me toss this out there. I'm running the amp off an Adcom GTP-500 preamp. It had good reviews when I bought it (1990ish) but probably not the best these days. What effect does the preamp have on the overall sound and is that something worth looking into as a way to improve the sound?

    There certainly are better preamps. Even so, I bet that Adcom is no slouch.

    I admit that I never had an interest in the Tuner/Preamps. I had a GFP-565 for a couple years, liked it a lot. It went away when I went multi-channel with a preamp/processor.

    As much as I’ve enjoyed the perks of NO passive filters* in my system, unless you have a thorough understanding of those XOs, I believe going active would likely be a step back.
