Thank you. excellent answer. I like the B&W's. I think the 703 will give a little more brightness and bass. The B&W 603 sounded excellent. . I guess the 703 will improve the sound?
Sounds to me like you have your eyes set on the B&W. I don't doubt that they are great speakers, but speakers are a very personal choice, and you really should try to audition and let your ears decide. I used to do this when I first joined the forum - I had my mind set on a Rotel amp with my old B&W DM602 S3, and all I was looking for (subconciously) was confirmation that it will be the amp to get. The people here suggested all kinds of stuff, but I just ended up auditioning an older gen Rega Brio and a Yamaha AS 500 - both of which were a bad match for my tastes - but I was EXPECTING not to like them when I went out auditioning. Then, convinced that Rotel was the way to go, I skipped on auditioning great amps from Arcam, Naim and Musical Fidelity. So I ended up getting a Rotel RA 1520, and when I was still unsatisfied, I got the B&W CM5, which were better, but still let down by the amplification (imo). In the end, I sold them one by one and replaced the lot with more expensive stuff, but stuff I AUDITIONED first.
Moral of the story is that, the collective hive-mind will yield great suggestions, all you have to do is keep an open mind. Millenia_one's list is a great starting point, imo, and gives you some speakers with different presentations so you have a varied pallette from where to choose. I'm not the biggest fan of Monitor Audio and Kef, but love the Revels and some Focals, for instance.
I also agree that B&W like a lot of current. so Musical Fidelity is a great suggestions (even their entry M2si can give something like 25 amp peak current, which is quite a lot), so if the linked one is too dear, something like a Musical Fidelity M5si might be just what the doctor ordered. If you wanna stick with Roksan, a 2nd hand Roksan Caspian might be better suited.
But if you don't have the new speakers yet, do try some other amp/speaker combinations, like a Naim Atom + Wharfedale Linton, or Cyrus One HD + Fyne Audio F501 (or 502), or Acoustic Energy and Spendor speakers with whatever amp the dealer suggests.
