Sun Audio sounds like Air Tight or AN?

I own a lovely pair of Air Tight 211 monoblocs. But, I enjoy kit building too, so I was thinking of building some Audio Note 300b or 2a3 kit. Then, I came across the Sun Audio and see that they use the Tamura transformers.

I'd love to hear the impressions of any goners who have experience comparing these three makers. Specifically, a) does the Sun Audio sound like Air Tight, and b) how does the Sun Audio compare to the Audio Note?

Thanks for giving it a go. Jeff
