My superline is powered from the 282. Which is itself powered from a Supercap DR.
I currently have a spare Hicap DR and a 4-5 din lead.
Is there any benefit in powering the SL from the Hicap rather than from the 282?
You’ll need to try it. Some prefer one, some prefer the other.

With a SCdr on a 252 you’d get a dedicated DR rail from the SCdr just for the powered Aux input on the 252 so in that scenario, using the powered aux would be better but with a 282 it’s different.
The 282 takes two feeds from the SCdr. One for the left channel, the other for the right. When you use the powered Aux, one channel in the 282 is on a dedicated DC rail, the other is shared with powered Aux. So it might not be best for either the Superline or the 282.
I run my SCdr into the 282, and use a separate HCdr to power my Stageline.

As HH has said,I’ll just have to try it.
With the 282 still on holiday to Sheffield and the 72 standing in, ill have to get the Hicap out and power the SL. I tried a pair of serviced 323k cards last weekend in the 72, and whilst initially ok, they were limited.
I really need the 282 back for a fair test, but i can see the benefit of the Hicap. Less so if i had a 252.

You might even prefer 282/Hicap with Superline/Supercap.

Absolutely. Does the OP have a SuperLine Burndy?

No SL Burndy. (Un) fortunately.
I was trying to avoid that SC/SL rabbit hole!
What rabbit hole is that? I don’t understand. It’s all pretty straightforward. Same as connecting to a HCdr in fact except with a fatter cable.
I run my 282 with a pair of HiCap’s and my Superline with a HiCap (all DR’s), sounds stunning!
I’m trying to keep to what ive got rather than buy a burndy. I can see that to get the best from a SC you need to use a burndy.
I sold one of my Hicap DRs, so just down to one, plus the Supercap DR.
I’d definitely give that HiCap a go at powering your SL, mines doing a lovely job of that right now…

Maybe a dealer can lend you one over a weekend?
I might try that. Not this w/e as i’m off to Warsaw early tomorrow.
I think I’ve tried a few ps options for my superline. Top is the supercap via a Burndy, which is the same as a Snaxo Burndy if you end up looking for a used one. After that my preference is for powering from a pre amp, though which pre amp has quite an effect they tend to give a more fluid result, if a bit less detailed. This even includes using the supercap via a Snaic, when I first got my 552 it freed up the supercap from my 282 but I didn’t have the Burndy, it didn’t take long to decide on AUX power instead until the Burndy arrived.
I revisited the 282 recently but kept the supercap on the superline and powered it from a Hicap and I think I missed a trick the first time round in putting my supercap on the 282 rather than the superline.

I’ll be honest Yeti, I prefer my twin HiCap’s to the SuperCap option.
I did try both and at first thought the SC was the business, but when I went back to 2x HC I found the overall tone and presentation more enjoyable

I’ve only ever had one Hicap but I did try both halves of a Flatcap 2x on my 282 as that’s the ps I had when I bought it but I preferred the more diffuse but larger scale effect from just half of it. A whole FC was a bit too Stonehenge, as realised by Spinal Tap.
I bought my superline before the Hicap, though I’d intended to get a Hicap when I went into the shop. AUX power still won out even from half a FC powering the pre, though I only compared it to the other half of the FC.

The likelihood is that it is just fine as it is. The SL is being powered by the Supercap all-be-it via the 282.
The Superline does not take much power so I think the SC is not going to notice.
Powering the SL via a Hicap will make it sound a bit different as it has different characteristics to the SC but whether that is better to your ears is another matter. I think it will come down to personal taste.
For what it is worth I tried a Stageline being powered by a 202 which was powered by a hicap. Which was nice. I tried a separate power supply for the Stageline using a Flatcap XS and Hicap but in that case it made no real difference and no better than getting the power via the preamp and Hicap.

Dug out the Hicap DR, 4-5 cable and 5 pin snaic. It is certainly better than a set of serviced 323k cards in the 72.
Im unable to comment on my own question as the 282 is still away. But once back, ill have a play.
