Supercap and 62/72

Hi-Fi Corner
22

I compared a 82 using just a SINGLE Snaic from the SC (so really a Hicap configuration) to a Hicap.
Even when using only half of the voltage rails that the 82 could access within the SC, it was still comfortably ahead of the Hicap. Indeed there was a bigger difference between the Hicap and 82/Single rail SC, than between the single rail/SC and the dual rail SC after the 2nd Snaic was added to the mix.

And I would almost bet (although I have not tried it) that a single Snaic/SC to the 82 would outdo the 82 with 2 Hicaps.
One quiet voltage rail is better than 2 noisy ones!

Apart from the 52 (with internal phono boards), the component that accesses the most voltage rails inside the SC is the Snaxo36(2) which I believe taps into 8 of voltage rails. Which is why a SC on the 362 is a bigger boost than a Snaxo on the 24(2) which uses fewer rails.

Was this a ā€˜board-pulledā€™ 72, which maximizes its raw performance (at the expense of having no phono inputs, or buffered tape outputs).

Hello,
I have an Urika 1. I removed the phono cards and replaced them with two 326 signal bridge cards, in case I want to use a line source on the RCA WBT Nextgen 110 connectors . I also use NA 729 synchronised input buffer modules, NA 324 modules for output to Headline, NA 321 gain modules and NA 325 delay circuit module.
The best results are obtained with the Din input. I use a Qed Reference Audio 40 balanced cable, modified to semi-balanced with the shielding on the negative terminals of the WBT Nextgen Arg plugs connected to the Urika pre-phono outputs, and on the 72 side the cable shielding is disabled without shielding. on the 180Ā° 5-pin DIN plug. Semi-balanced wiring allows two identical wires for the + and - of the signal.
