I've been offered 2 very interesting tube amps, along with good discount and free of charge installment.
Cary CAD 300 SEI $ 3900 and'
 Manley Stingray $ 1650,
the problem is i have a B&W 683, i wonder if either of them have enough power to drive my speakers,
because i've tested them at the dealer with B&W 685 & B&W 684, and it sounded they're lack of bass (unfortunately the dealer didn't have a 683 stock) specially the [B]Cary CAD 300 SEI [B], but the depth and the mid & high are superb.
Should i take any of them?
