Totem and Bel Canto?

The Bel Canto should very easily beat the NAD. Haven't heard Bel Canto with Totems, so I'm not implying that it'll have a better (or even a good) synergy; just stating Bel Canto is far better overall IMO. Not bashing NAD at all. I've owned a few NAD integrateds over the years and really liked their performance for the dollar. However, Bel Canto is easily a step or two up.

Doesn't mean you'll prefer Bel Canto to NAD either. But I think you'd agree it's better if you heard them both.

Naim and Totem pair up quite well. I've heard many combos of them and never heard anything less than stellar.

Bryston also pairs up equally well IMO. A bit different, but equally well. Simaudio is another great match.

Bryston B60s go for under $1k here, depending on age and features (remote, DAC, phono). I like Bryston a bit better than Naim, as it's more 3D and a tad more relaxed sound.

The Arros aren't impossible to drive, but I wouldn't call them easy by any means. They've got an odd impedence load that requires a stable power supply. You don't need kilowatts to open them up, but you do need an amp that doesn't have difficulty delivering current into 4 ohms and less. Not sure what they actually dip down to, but I'm pretty sure it's less than 4 ohms. If impedence isn't the issue, phase angle may very well be.

A Nait 5i has a power supply that'll take care of them.

The Rainmakers and Arros are pretty similar. Totem doesn't design lines per se (as in B&W 683, 684, 685). Every speaker is it's own individual speaker. However, the Arros and Rainmakers are quite often paired up together in surround applications. Same can be said for the Sttaf and Mites. I think the Arros and Rainmakers use the same driver, but different tweeter. Sttaf and Mite is most likely the same thing.

Just a heads up on Totem in general.
