whats the best pre amp to pair with Bryston 4b cubed? A

Long time Bryston owner of multiple iterations of their amps.Tube pre amp is essential to flesh out the linear presentation and provide that deeper richer musical presentation.Always used Audio Research tube pre amps,well documented history between that marriage.Of course there are other accomplished pre tube pre amps which will meet your needs.

So you have not bought the Bryston amp yet?

I’m going to assume we can pretty much start off fresh. Keep the Arcam integrated and...this is going to sound like a broken record but get a set of Triangle Deltas ( or better). The Triangles will give you what the Arcam doesn’t with the Totems. Tons of imaging and deep deep sound stage. A huge step up and well within the budget. Better electronics WILL get you more from the Totems but for the same money you can have your bucket list system that is way above a change in just the electronics.

yes well if the bryston amp is not a done deal, my no-brainer suggestion is get a hegel h190 and be done... superb amp, sweet combo with totems

The Arcam is a nice amp. I'm not convinced it's going to make a huge jump.
