Vitus Ri100 with Dyns Good Combo?

Thanks spinaker01, yes I agree with you on the A21 is the weak link. It doesn't have the control on the lower register. Mids is not quite there. Have a chance to pick up a used Ri100. But there isn't a chance to listen the amp on the Contours, hence the question.  Am afraid the newer model Ri101 is out of the budget. 

Could go to the new JC5, but the owner of the above systems have tried his speakers with Gryphon Diablo 300 with DAC module installed. The differences are quite stark. From top to bottom everything opened up substantially. The whole systems just come alive. Not sure the JC5 can keep up.  Btw, I am in Australia :)

Thanks for the insight regarding the Ri100 melbguyone. Will check out your suggestions. 

Thanks @audiotroy . The systems above are not mine, it belongs to my mate. After hearing the Contour 5.4 driven by the Gryphon Diablo, he wanted to try something else. At this stage a new  Vitus/T+A/Gryphon is out of his budget, well....atm. :)
