Out of the box the io is well built and heavy.I connected it to my CA651 CD player (it has similar specs to the Rega Saturn with 2 X 8742 Dacs) and to Dali Oberon 1 speakers.Initially the sound is bright and cold.But after using it for a few days and leaving it switched on all day the sound is warmer richer and more enjoyable.The amp at a quarter volume is just right for me. Turned to about 11 o’clock it becomes quite loud.It drives the speakers really well. The sound is beautiful, from good solid bass right through to an almost hypnotic mid to treble highs. A very clean and neutral sound.I played the sound track to the Gladiator and when I closed my eyes I thought I was actually there.The io can sound extremely subtle with quiet details and it can also play hard without distortion with drums and cymbals etc.It doesn’t quite drive my AE floor standing speakers as well as my 50w/ch Arcam Alpha. But the midrange on the io is sharper/clear. So the Brio might be a better option for certain speakers.Two months on and I listen to it nearly everyday. The sound with the Oberon 1 is clear and spacious but a bit too clear/bright. So I added a Rel T-Zero sub and the sound is better, fuller and more rounded on some music.3 Months on I play the album Surrender by the Chemical Brothers and Ghosts by Coldplay. With out the sub woofer the sound was fantastic but with the sub it was hello night club.I added a good quality turntable and the sound is superb. The Oberon 1’s really suit vinyl with this amp. A perfect match. Clear open, smooth and detailed. Vocals are good.I could easily live with this amp, (paired with good input sources and good speakers) at the expense of any other system.Listen to something you really like and the sound draws you in. The midrange is particularly good.

I'm sure you'll have already seen the many glowing reviews of this "entry level" Rega amp. I certainly agree with them - it sounds awesome, and is (unsurprisingly) a great partner for my Planar 2 deck.It's also paired with an Azur 851N from a price bracket or two higher, and performs brilliantly with that too. There's tons of detail, and for anyone with a 'normal' sized room you really don't need to worry about the quoted output wattage - it drives at a good volume without any signs of strain or stress.There's a real flow and dancing quality to the sound which is a delight.Why only 4 stars then? The volume control is infuriating! It's massively over-sensitive - at sensible listening volumes for a smaller room it's barely off the zero mark, and the smallest of adjustments makes a huge difference in output.Listening quietly at night is out of the question, it's daytime volumes or silence... The same is true no matter what source I connect. It's made worse by the remote, which can only adjust the volume in large increments.If you love to blast your music out and/or live in a detached house then great - but if you're in a flat and/or aren't a complete volume monster then this is a serious limitation. Such a shame, as it's an annoyance every time I use it, and it's otherwise pretty much perfect.
