If you can, contact Upscale Audio. I bought one of them there...I won't say which...because you should decide for yourself what is good for your system.
The Musical Fidelity is smoother, the Cary has more difference from loud to soft. For someone with a system that struggles to get top end response, the Cary will be a better choice. If someone has way too much top end the MF may be best.
I spent some time with both. But I have been a customer at Upscale for a while and bought my other gear there. If you know Kevin, he will let you stay there for an extended time and has good advice.
You may get more info from upscaleaudio.com too..that's a good start. I think they sell a lot of both
