If your system gets along well with the TQ Black you may not so much be the target audience for the Green, which - like the Blue - is forgiving for systems that need forgiving. I have the feeling your system is in the Black-Ultra arena, where the slightly softening aspect of the Blue-Green is not so important. I perceive, rightly or wrongly, that my Rega Brio-R-Apollo-R system is in the Blue-Green arena - but if I had I had a Cyrus 8A and equivalent CD player, I would be in Black-Ultra.
As far as i understand it, the TQ range is akin to Intel's microprocessor “tick” and "tock" stages - (roughly) the "tick" a stage of technology, the "tock" a stage of microarchitecture. In the TQ world, the Black has the technology of the Blue but a stage further in audio "microarchitecture" - a "tock". The Green incorporates the "microarchitecture" of the Black but in a new technology - a "tick". The Ultras have the technology of the Green plus a new "microarchitecture" - another "tock".
TQ do not disclose materials or structure, but I think of the Blue and Green as being "copper" sounding, and the Black and Ultra a "silver' sound, if "copper" is dark and tolerant; "silver" as bright and intolerant. In looks the Blue and Black are "thin", the Green and Ultra are "thick". So the Blue is "copper" and thin, the Black silver and thin, the Green copper and thick, the Ultra silver and thick.......(no relationship to real materials!) In practice I am just suggesting one's system may most suited to a "tick" (Blue and Green), or a "tock" (Black and Ultra) - it is not just a problem of price...
