Difference between Croft Transvale Integrated (CGI and Syntegra) and Integrated R?

[ElTwang]

Hi Croft experts,

I'm currently running an Integrated R and am very happy with it.
But I kind of like the looks of old TransValve boxes better.

Can anyone tell me about the differences soundwise between the Croft Transvale Integrated (CGI and Syntegra) and Integrated R?

Ask Glenn - He designed them!

I don't think he made them though.

According to Glenn, his latest products are the best he has ever done.
