I have nac82 & 2 hicaps & 2 tpx1, apx3, whest custom p/s for nac72 & a dual Teddy Pardo.
I have tried all & the Teddy Pardo rules the roost.
Less wiring showing & all in one neat box.
Now use hicap or tpx1 to power CD5.
The others are shared on a second system via NAC72 with Avondale 821 boards driving SBL,s
rest of sad collection, 135,s 2 x250, 180, collection of 32.5,s.
Avondale Monoblocks driven by Linn Kairn, source LP12. via rega xel,s
Main system CD based Pioneer PD75 with seperate DAC, IPL Transmission lines Bi-Amped with 135,s & 250 driven by NAC82 with 15db attenuated leads.
Summary. The Naim power supplies are overrated & expensive, plus,very old fashioned design. Stick with Les & Teddy p/s for value & sound. imo.
