Hi GoodSound!,
I am from India. I have B&W 683 floorstanding speakers. I want to match an amplifier to these speakers. Can you help me out? Two amplifiers are on my mind: the Cayin 265Ai (pure class A) and the Sugden A21a (pure class A). Will these amps match with my speakers or are there other amplifiers you would suggest?
Thank you,
Kaushik
Although I've owned a number of B&W speakers in my lifetime, I'm not familiar with the 683s, so I looked up the B&W-supplied specs to gather a little more information. Their sensitivity is rated as 90dB, which is a little bit above average, and the impedance is rated as 8 ohms, but with a 3-ohm minimum. That 3-ohm spec indicates that they should be used with an amplifier with good current capability, although the highish sensitivity indicates that it doesn't need to deliver all that many watts of power.
Overall, that bodes well for the amps you've chosen -- their manufacturer-supplied specs indicate power output of less than 50Wpc for both (into 8 ohms), and, from what I can tell, the dip to 3 ohms shouldn't be an issue with either amp. But will the 683s play loud enough for you with these amps? There's no easy way to say because it will depend on your room size and, also, how loud is loud enough for your tastes. I hope that helps. . . . Doug Schneider
