Bi-amp Revel F208s using Denon 8500HA?

[pmar4015]

I realize the following is controversial (in terms of efficacy (or lack thereof)) but I can’t help but think there may be some benefit in bi-amping my front Left and Right Revel F208 speakers in my current 7.1.2 setup. To complicate matters, I am running Three Outlaw 2220s to power my FRONT Left, Center, and Right speakers (center speaker is a Klipsch R-5800 W II (behind an acoustically transparent projection screen)).

I am thinking that if I repurpose two of the three Outlaw 2220s for use as external amplification to power my two main surrounds (keeping one Outlaw 2220 powering my Center Channel (as I am doing now)) and then bi-amping my Revels via the onboard 8500HA amplifiers I ‘may’ receive some benefit considering the 8500HA has 13 on-board amplifiers and I am currently only using 6 on-board amplifiers (understanding the Outlaw 2220 is rated for 200 watts into 8 ohms but maybe if I bi-amp (thus using 8 on-board amplifiers) I can squeeze out maybe 250 watts per Left/Right channel?). My goal is to put as much power as I can into the Revels (given they are rated for up to 300 watts) using my current set-up.

Here is my current setup -

Receiver: Denon 8500HA (powering L/R Main Surround speakers; Top Middle Ceiling Atmos Speakers; Back surround Left/Right speakers)
External Amps: Three Outlaw Audio 2220 monoblocks (powering Main L/R/C speakers)
Speakers: (A) Bed Layer (7 spkrs) - (i) Front L/R: Revel Proforma3 F208; (ii) Center: Klipsch R-5800-W II (behind an acoustically transparent projection screen); (iii) Main Surround L/R: ELAC Debut 2.0 OW4.2; (iv) Rear Surround L/R: ELAC Debut 2.0 OW4.2 ; (B) Height Layer (2 speakers) (i) Top Middle L/R: Revel IW65; (C) Subwoofers (5 spkrs) - SVS PB-1000 (4 subs)/Monoprice Monolith M-215 (1 sub)
Gaming Console: XBOX Series X; Blu-ray Player: Sony UBP- X700(M); Projector: Sony VPL-VW325ES; Streaming Device: Apple TV (2021 gen)/Hardware DSP: MiniDSP 2X4 HD (Managing 3 subs (4 SVS PB-1000 co-located; collapsing into 2 subs)/Software DSP: MultEQ-X

Or maybe I just buy two more Outlaws 2220s to bi-amp the Revels (or just do nothing at all)?

Thoughts?

It won't cost anything to try it with the 8500, so I'd start there.

I'm with Wayne... try the 8500 and see if you notice any difference. Chances are pretty good you are not anywhere close to maxing out the 2220s as it is, so you might gain a little headroom, but I'm not sure it would ever be needed, unless you are pushing insanely loud levels.

Thanks to both!
