I have a SUT that has been built for me using Cinemag 1254's, I also have Hashimoto SUT produced by the same person.
I most enjoy the presentation of the Cinemag, they are less rich than the Hashimoto, but it is difficult to describe the Hashimoto as rich, it the only SUT in use. For the delicacy and refined presentation, the Hashimoto nails it.
Both the above SUT's can be said to have a variance of rich hue in their presentation when compared to a Head Amp.
