Hello, I enjoy all of the information on this forum regarding the wonderful SDA line.

I was wondering if anyone had some information of whether or not the NAD 2400 or 2700 two channel amps would A: be a good match for my sda 2b's? and B: are they common ground so as to actually work with them at all?

I am also considering the Adcom GFA 545.

Any advice would be greatly appreciated
Thanks!

    I dont think the 545 is common ground and if not you can tie the neg posts to make it so

    I have the Adcom 555, 545 and 5400, all are common ground.

    I also have the NAD 3400PE integrated, which uses the same 2400 amp. This NAD is also common ground. I have driven a pair of SDA 1Bs with the Adcom 555, but have since moved them to a room of their own driven with the NAD 3400 which really opens them up. The Adcom sounded great, but I do like the NAD much better.

    I currently run the SDA's off a Sonny 555es which I love. I think its around 110 wpc, but I am assuming the NAD 2400 would be a significant improvement.
    any thoughts?

    I am positive the Adcom 5400 is NOT common ground.
