Any comments on TA-2020 versus 2021?
Also, any observations on whether a big linear PSU sounds better than, say, a 5A switched mode PSU?

Wow, I thought I did well for £17! Don't bother with the tone controls, good job there is a defeat button.Quote:

Thanks, Paul. I know of old that your PSUs are excellent for low power duties and indeed have PH supplies for my Technics SL-1210, Logitech Touch and Beresford Bushmaster, all of which significantly enhance SQ over the original PSU.
I would be very interested in evaluating a PR3i 14V module and reporting back here on its performance. Shall we continue by PM?
A good linear supply made all the difference to the Golds Martin, well worth doing IMHO.
maplins linear psu made a noticeable improvement to my original bantum..... couldn't tell you which one though....
Ah, that's good to hear chaps. I'll start planning a brute 14.5V 5A linear PSU build, then (the max recommended operating conditions for the TA-2021).
I use a good linear power supply really makes a difference but so does using a really good pre too on the Bantam I am now at the point where it be hard to go back to anything else

I'm running the Mini-T on a 12V SMPS right now. I have a 14V one arriving tomorrow. Soon I'll start building a 14.5V linear PSU. I'll be able to compare and report on them in due course.
