Thanks for the info , tbh I'm bit undecided if I should go for Paradise or SUT , hearing Paradise would be of great help , anyone with one in Essex please let me know.
Only available Paradise at the moment is fully populated one , I PM'd Joachim from Diyaudio (might have odd boards laying around) and posted wanted add there , so there is a chance .
Have you applied any tweaks/changes to R2 boards apart from better components matching?
Correct me if I'm wrong , main boards require something betweem 26.5-27.5 VDC , positive and negative rails obviously , what's the current requiremnt?
Regards

You could also ask whether anyone has moved from SUT's to Paradise.

The psu is 25-26.5v +/- at 300mA per rail.

I built misterdogs boards. Upgraded opamp in servo, lower dc offset. Transistors matched to better than 1%, riaa matched to 0.1%, 2sk170 on the back end of the current mirrors, j113s on the stunts, matched output stage. Shunt stability mod is added, with extra hf decoupling of the first stage of the shunt.

There component cost for a pair of paradise main boards is over 400. You'll need to buy parts from eight different vendors and if you can match a full set of transistors from fewer than 500 parts you'll be doing well. Total build time for a pair of main boards is close to 50 hours and that's not including the hunting the parts out at various suppliers.

If I was selling misterdogs boards I'd be asking twice as much.

No, no one has moved to suts.

I might be lucky to audition Paradise in couple of weeks , there is one not far from me.
