Who Has A BHK 250 & How Do You Like It?

That is a no brainer buy the BHK the Bryston sound tends to be a bit thread bare, clean, tight bass but not a particularly warm sound.

Good luck.

I have a BHK 250 and I too have wondered what it would sound like with Maggie 1.7i's. Unless someone has actual experience with this combination, opinions on how this amp sounds with one speaker don't necessarily correlate with other speakers. I've no experience with Bryston. In my system, I don't find the BHK amp to be "warm" at all and would characterize it as neutral. I had to do a bit of tweaking with different power cords, tubes, and interconnects to get it's tonality to suit me. Once I did, I love it and find it competitive with equipment at a much higher price point. Don't feel like you have to rush to jump on the amp for $4,800. PS Audio equipment is available at a discount from more than one retailer. 

Great info! Thanks photon46

Magnepan demonstrates with Bryston, designs with, and works very well together.
I have heard the whole Bryston stack Dac/ CDplayer Pre and 4B Cubed amp perform with Magnepans with musically engaging and effortless results.

I actually have the BHK Pre and BHK-250 combo with the 1.7s (not i). 
I think the MGs and the power amp mate very well together. Lots and lots of headroom and velvety sound with great soundstage. I did change the tubes to Tungsram tube for both the pre and power. At this price I would most highly recommend it.
