Rega Brio R bright???

I just have to speak up here....the BRIO R IS NOT BRIGHT! I have no idea what you are doing to it, but I've heard it with various speakers, Regas, Totems, Harbeths, and it is not bright......and I'd also say it is lunacy to pair it with Magnepans, for any serious listening. And even though it will relax after break in, it is not even bright straight out of the box. I have not heard it with the Dynaudios. Dynaudios pair well with the new Hagel gear....

I like how you say the voices are strange, and ask if perhaps it's the rega or arc am....maybe it's just the Dynaudios are a bad match.....

You have to understand something.....what you are describing with some of these amps is only when you are trying to combine them with the Dynaudios....if you heard them with other brands of speakers you might be surprised....why not go for what Dynaudio people use, or some of them anyway....I'm sure if you ask you'll still get a thousand different answers, just from them....I can offer no other advice, since I am not a fan of Dynaudio speakers...drivers yes, speakers no.....good luck....
