I bought an Aura AV50 integrated amp 2nd hand a few years ago. It has worked perfectly well, but does get hot. I'm now looking to upgrade my system. Have already bought some dynaudio 72 4 ohm l/r speakers (which the Aura drives for audio and l/r in AV system). The Aura worked well with these speakers in the shop. However, i hear that these dyns need lots of amp to drive them. But i don't even know the wattage on the amp. In fact, I'm completely lacking in any info on the Aura (it was popular in the mid-90s apparently). Has anybody got any data/opinion on the Aura amp. Is it going to be enough to drive these speakers? What other amp would anybody recommend? Thanks
