Hi Mike and Bonzo,
Thanks for the input.
I was recommended by my friend to listen Devialet + Vivid combination which occasionally listened to it during some shows.
The more I read on Devialet design gave me a feeling it's a Class D amp, I may be wrong on it. However, I would prefer Class A amp but with limited budget, I have to manage with RI-100, a Class AB amp and hope the RI-100 and Vivid B1 will have warm, neutrality and transparency.
Coming back to speaker cable, Mike, which range of Kimber and Siltech cable you have on your system?
Have any Vitus owners try out Cardas and MIT speaker cable?
The Devialet is a great all-in-one box solution. Sonically, to my ears, it sounds more Class A, than Class D, but it's a hybrid of both as you know. A D400 is not going to beat a $20,000 amp in most cases. People need to keep in mind that the Devialet gives you an amp, preamp, DAC, phonostage, and much more. If you break out each component, than maybe the amp/preamp section is in the $10-12K range (in terms of competition). It's a great value for sure.
If you're doing Vitus, try to save up for the Class A. You say you're a Class A kind of guy, than why would you settle for AB?
