Phoenix Gold Phorum

I am trying to decide if I should use a 2125 or a 2125TA to power my midbass drivers. I am using four 4-ohm Image Dynamics 6.5", two per door. I know the 2125 put out more power at 4 ohms, but at two ohms stereo, which is what I will be using, the power output looks about even. So assuming that is the case, is there any sq difference between the two? My first thought is to use the TA, but then I remembered that the TA I have only has 6800uf rail caps, while my original 2125s have 10,000uf rail caps. Fortunately the rail caps on both of my original 2125s look pretty good still, so I don't think I will need to replace them any time soon, and if I did, I hope to be able to source some properly sized 10,000uf caps by then. Other than the rail caps, I can't think of anything to differentiate the two in this application.

Thoughts?

This is a matter of taste I guess; I prefer the first series MS amps because of the greater amount of craftmanship displayed in them [every device having it's own screw to hold it down].
As far as SQ....I've had so much MS amps through my hands already, and never noticed any substancial difference in sound between them.
Only time I experienced that, when listening in A-B config. is that the early grey amps tend to sound "punchier" in bass/midbass use, where there is no difference IMO in highs.
So choosing between a NORMAL, or TA version, I'd say you won't be able to tell the difference.
If you would choose between a GREY MS amp, or NORMAL/ TA I'd defenately go for the GREY series [B-BOARD].
