Integrated Amplifier for Bowers & Wilkins 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.

Really depends on what sound characteristics and improvements you’re looking for. 

The X3 is great but the 390 has a better DAC and has a streamer module so you don't need to buy a separate streamer

+1 on BAT hybrid integrated can be found used for $5K

CODA CSIB is a US-made SS integrated, very smooth and pure sound, and can be found used for $4K

BTW the Gold Note is decent but for that money you can do better, get a Holo Audio Spring 3 and Red streamer combo instead, or Gustard R26 for even less $

Definitely need a high current amp......Musical Fidelity works great with B&W 702’s. Also Audio GD tube pre w/ Peachtree GaN 400 amp is detailed and sweet with an enormous soundstage that goes Way beyond the speakers for a Very Live sound. good luck.
