Integrated Amplifier for Bowers & Wilkins 702 S2

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.

I tested both the Michi X3 and Hegel H390 using their internal DACs from a music streamer and settled on the H390. Both are good, but the overall sound of the Hegel was more refined where it made listening more relaxing, the Michi had a slight edginess by comparison. I don’t think you can go wrong with either, but my summation was the dac in the Hegel was the reason it sounded better to me. If you plan to ever get an external dac I recommend trying them with one, it might make your mind up. I own Spendor speakers, so different sound to your B&Ws.

Are you in USA? If you are call John Rutan at Audio Connection. You need a Belles American made integrated amp. They are under 5k but compete with amps over 10-20k.
