Another zener follower ? for anyone who can answer..

Based upon the one answer i got on the zener emitter follower regulator question i had i decided to keep it as is except for changing the power transistor to the mje3055 and 2955 10a max current npn and pnp..These are to220 with heatsinks that i attached, replaced solely because the original to92 sanyo versions were getting way too hot for my liking..I have been doing alot of listwning and noticed one thing, the opa627 ops being powered sound so damn good and revealing and liquid with absolutely no grain and deep bass that seemed to be slightly MIA till now.. I would just like to know from anyone who can tell me what is the deal here, the datasheet only really states these as being general purpose...How have these made such a drastic difference in sound??..I also have noticed my rails being dead stable at 15.5 +/-, my only guess is because of the added heat sink and better dissapation being to220 is causing the better stability, but soundwise , its just bliss.

You've reduced the efficiency of the regulator. - Mark Kelly 22:42:40 10/02/05 (3)

Efficacy not efficiency - Mark Kelly 03:46:38 10/03/05 (0)

so how does that explain the positive changes?? - Vynuhl.Addict 23:11:24 10/02/05 (1)
