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?

Hi Martin,
A big linear PSU like the SR5 or the SR7 does work very well with class T amps like the DIY Paradise Charlise and Virtue Audio amps that use these chips, as the supply line rejection is not usually that good on these designs. I see no reason why your amp should not see a benefit also. If you have time for a DIY project I can send you a high power PR3iEHD-12/14 linear regulator for R&D purposes.
Regards,
Paul

High Performance Power Supply upgrades

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).

Would be interested in your findings Martin, for what it is worth, l have three T-amps and the PSU is so important and they do make a difference- big time, my battery powered Virtue Audio Sensation M451 sounds quite awesome frankly...
System; Michell Gyrodec SE/ Orbe Clamp/ Gert Pedersen armboard mod/ HR PSU/ SME V / J7 Tonearm cable/Ortofon Cadenza Black// Jez Arkless Turbo nutter B------ /Trichord Dino+
Amplification and loudspeaker set up is at the moment being split into two groups, comprising the following;
1. Same sources as above; SONY TAF-770ES/SONY CDP761E/Cable Talk 3.1 loudspeakercable/ Harbeth Compact7ES2/ Stands
2. Virtue Audio Sensation M451battery PSU, ClarityCaps upgrade/ Sensation M901/Russian PIO caps with Teflon bypass caps upgrade/ JT Dynamic PSU with various tweaks/ Connex Audio 5N Litz loudspeaker cable, Impulse H6 Loudspeakers.

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.
