Elac DBR62 amplifier recommendation

Thanks! I will
I have the Elac Uni-Fi Reference UBR62 speakers paired with an Adcom GFA-5802 and Velodyne HGS18B6 subwoofer, crossed over at 100 Hz. Although my UBR62 speakers have great sound staging and imaging, and good detail, they lack dynamics, which I suspect you may be hearing in your Elac speakers. It certainly is not for lack of power, though - my GFA-5802 has 300 W/ch into 8 ohms and 450 W/ch into 4 ohms, and it had loads of dynamics when paired with custom speakers using Focal drivers I used to have.

Wonderful amplifier for sure but your power ratings are not to spec.

The amp switched to protective mode after some listening at high volumes. Doesn’t that happen if the amp is overloded?

I think you transposed 8ohm vs 4ohm power in your post. That said, I’m not even sure how you could be in the same room with them to have engaged protective mode. It must have been deafening.

Protective mode can be engaged due to a fault in a driver. ie. Intermittently shorting voice coil. Have you frequency swept the speakers lately?

That has never happened to me. It could be the amp got too hot, or perhaps something wrong with a speaker. Check the speakers as Doodski suggested. If they are fine, then probably it is that the amp got too hot. If that is the case, you may want an amp more suitable for those listening levels. My GFA-5802 doesn't get abnormally warm at my listening levels. Indeed, the chassis of my miniDSP SHD pre-amp/DSP runs hotter than my amp, which I do find strange.

Yeah I just got a good deal on a Yamaha A-S1100. It should deliver enough power, or there has to be something wrong with the speakers/subs.

Are you connecting the subs via high level connections? That could be a problem - and maybe even more so if you connect it that way to a class D amp.

Yeah. The subs are made to be connected that way.. They only differentiate on balanced/unbalanced/mono-blocks i believe, not amplifier-class
