NBS Classic vs. Monitor vs Omega Series

Hi, Has any one here ever listened to and compared the differences among NBS's Classic line versus its Monitor and Omega lines at the same price levels? For example, how does a Master 2 compare to a Monitor 2 or an Omega 2? This applies to interconnects, speaker cables and power cords.

Also, any knowlege of differences among Classic I, Classic II and Classic III products will be greatly appreciated. For example, is a Master III better than a Master II? If so, is its performance closer to a Professional II or Statement II?

The NBS website provides very little information, so it has been difficult to do much research on these topics. Thank you in advance for sharing your knowlege and experience.
That's very useful information, guys. Now that we have a comparison between the Monitor and the Omega series, I hope someone can provide a referece with the Classic series too!
I have used all the cables, I have 3 different systems 3 floors. I have the Omega 0's the professional 3's and monitors 1's. I have switched back and forth. I find the monitors to extend more than the pros but had an analytic sound. The pro's were warmer and fatter which makes them sound slower but they arn't. The omega's provide the best of both cables. What must be done is getting the right cable for your system and personal preferance. I like the warm sound. I have the omega's on the Vtl/Cat/Vkd5se. I like the pros on the Plinius 8200/Sony Cd/. I like the pros/omega combination on the Bat500/dk5se/Herron system which i hope to get omega's eventually
Thanks a million Jazzhelp!!! This is most helpful. Based on you input and what I have heard, I think I have a better feel for the differences now.
Walter is a great guy, very cooperative and understanding he may be willing to let you swap and audition cables give him a call you properly can work something out.
