from what i have personally heard
1. Jadis JA30 + B&W Signature 805: emotional, refined, heavenly (i believe any Jadis integrated would produce a similar sound with B&W 805S)
2. Jeff Rowland Concerto + B&W 804S: powerful, clear, detailed, refined, exciting
3. McIntosh MA6500 + B&W Signature 805: easy to listen to, relaxed, enjoyable
hope this helps and best of luck!
