Integrated Amplifier for Bowers & Wilkins 702 S2

BAT VK-300SE or VK-3000SE (both used). Excellence.

Based on the impedance measurements at Stereophile, it is worth considering amps with high current drive.  The Luxman 507s may work but the 509s would be better.

Thanks for your comments. All of them are precious. I checked Hegel, It's looks perfect. I guess in such case I don't need to add a different Dac. I can drive with just a Music streamer. So, I'm between Hegel H390 and Michi X3 what would you say about the Michi X3 with B&W 702 S2 ?

I can only tell you I drove my B&W CM10s with a Rogue Pharaoh with great results. I found a pair of 804D3s I couldn't pass up and they are spectacular with the Pharaoh . You see used Pharaohs selling for less than 2500 and Rogue also has very good customer service! 

I ran Tube pre and class D amp for years.  Only went to class A/B amp cause I never had a good one.  Would consider tube/class D again without hesitation.
