I just installed the Aberdeen upgraded power supply and if you own a TacT preamp, you should RUN to the phone and order one!!
This is not a minor tweak or upgrade, this is a change on par with or better than a component swap.
As Alex mentioned above, the new ps turns the TacT into an excellent preamp/dac. There is a marked improvement in dynamics, clarity, focus, and air.
I would write more, but I simply just want to get back to my system and put cd after cd in and listen. That line should mean more than any audiphile terms and banter I could type.
Thanks again for a great product Anthony.
