Need help for B W speaker and CJ Amp

I wanted to also add that my plans are to go with tube preamp. I know that will make it warm.

Cable would depend on what type of sound you want to achieve. Do you want to warm the sound or brighten it up. I am curious as to how the B&W sounds with the CJ. I have the N803 B&W; and the CJ 2500 is a consideration for me with possibly the CJ 17LS preamp.

I am using Marantz MA 700 mono's. There ok but not great. I have those until I can upgrade. I did bring home Jeff Rowland 112. It was close to perfect for me. I immediately heard how much better the Jeff Row was. I wanted just a little more warmth and perhaps with with cardas cables and a better pre it would be just right. Right now using Yamaha pre outs on receiver. Also demoed at the store an Ayre V-1 amp. Wow! Nothing could be harsh with that amp. When the time is right I'll bring that one home to try.
Audioquest ruby IE. Don't know what on speaker cable.

I am using audioquest but wouldn't recommend it. If you want to go warmer I would suggest Cardas golden cross. There is a lot of cardas for sell here at audiogon.
