Audio Research Ref 3 Opinions

How about Ref 3 vs. Ref 2 (MK1)? Any one has the experience? Is that true Ref 3 is not as warmer and sweeter as Ref 2 MK1? Thanks!

Now spent a few hours with the REF 3, it is a revelation.
Anyone knows which manufacturer or which kind of caps the four golden caps are? Teflon? oil impregnated?

Soundoc, please elaborate on your Ref 3 experience!

to my thought he Ref 3 is quieter, had greater dynamic range, and is more transparent. the noise floor is very low . the sound is extremely focused, clean, and transparent. the soundstage dimensions as with the former Ref 2 wide. tight bass and clean top. very good low level detail information. bass articuliation is in a class for itself. very holographic.

Soundoc:

Those are technical attributes that you have described.
Is it more musical than the Ref 2?

Thanks
