Well - I was planning to go with 3 x InRoom Silver LCRs and 4 x In Wall Silver Surrounds for my upcoming theater build. However, I've decided to step up to Gold LCRs instead. Because of the increased cost, I'm looking for places to offset. Ideally, I would be purchasing a Parasound Halo A31 to power the Gold LCRs. However, I can get two A23s for ~ 2/3 the cost of the A31. Would the 225 wpc @ 4 Ω of the A23 be sufficient, or will I need the extra power of the A31?
