NAC282 Dual Hicaps

That is a very informational thread! Thank you.

Olive SC arrived a bit after lunch, replaced the HC-DR on my Olive 82. Only managed to listen for about 5 min before jumping onto a conf call. Now I don’t have the golden ear like some of the members here who can hear nigh/day difference by simply re-arranging stacking order of their gears, but even to me the SC is a huge improvement over the HC-DR on the 82: sound stage width/depth increased, music is more relaxed but at the same time more impactful when called for, but what impressed me most is the organic, analogue like sound! Very happy with the upgrade.

Glad to hear your report. I’m always wondering if a supercap olive will provide better result than a modest hicap dr. Thank you,

Conscious bias is always at play. You like what you have spent money on. But if you like it, so what?
I’m sure if I had a 555psu or SCDR it would be better than my xpsdr or dual HC. Proper blind testing would perhaps give us a different answer. Being an engineer I always want to know why something sounds better. As you’d expect, the designer would want to know too.

Works both ways, if you really don’t want to spend the extra dollar, surely you can convince yourself the uplift isn’t worth it, you cannot hear an uplift, or you look for others opinions that concur with you.

Very difficult and I suppose the only real way to make a decision is to listen yourself in your own listening room👍

Has just arrived and plugged in to warm up. Can’t wait a full 24hrs for warm up time but 4 hours should suffice. I will start doing the comparison tonight. While I was waiting for an SC2 to arrive for a loaned test, an SCDR came up on a popular auction site for 60% off, and the seller had 100% positive feedback since 2004. I made an offer and DONE! Great seller, and shipped to me in 2 days! Will post opinion tomorrow.

I really wouldn’t post the serial number or some clown will be reselling it tomorrow.

Please let us know your findings, it will be very interesting.

Hmmm

As usual - all this talk about amplifiers without context to which sources being used

A 282 with a Supercap fronted by a chord mojo will sound inferior than a 282 with a single Hicap fronted with a chord Dave

It’s more useful (to my wallet) to mention sources used and also to think of the money used as a amount taken away from a source improvement in my humble opinion

I have to agree but the gentleman concerned has a similar front end to mine that is why I am interested in his opinion.

Recently I had the pleasure to hear a top maxed out source with Naim 552/500dr

No further upgrades possible ? Right ?

Welll… actually not…

The interconnects from source to preamp !

One of them sounded broken, one of them was fantastic.

I won’t get into which cable sounded better and which one worse but only to illustrate my earlier point of Context

The source to preamp interconnect is quite crucial to hearing that all important, source !

I agree that everything is subjective.

I discussed this very issue on another forum, with a source that I respect. The answer (from his extensive experience with the kit) is “no difference”.

From my own experience with the 82: moving from 1xHC to either 2xHC or 1xSC gives an obvious uplift in SQ because there are more 24V rails in play. The only contention is whether moving from 2xHC to 1xSC is beneficial.

I am assuming you are responding to my post…

I posted on the other thread…last bit of hear you bought, ahould have updated all of you. I will say for me, as I have tinnitus, it toned down the highs and gives a deeper, and more refined sound stage.

So to explain a little. Prior to adding the SCDR, my voicing was central, but came from a focal point of 0.5 square meters(just a reference number for explanation purposes), very focused. Now it seems that the voicing comes from a 1.0 square meter area, if that makes sense. Instruments, seem to be the same now, which creates more of a 3-D and full(er)sound, a little further into the room. My listening position triangle is 11.5ft from speaker centers to sitting position and 11.5ft between speakers.

What I do enjoy now, is that when I am awake at 6am with my coffee and the rest of the house sleeps, I enjoy my jazz, vocal and some folk music (Gilberto, Tord Gustafson, etc) at lower listening volumes. It seems as if the lower listening volume has a little more even delivery in frequencies. Bass, mids, treble are delivered evenly. That’s the best I can explain it. Hope that helps, and yea, it is subjective but I did do a comparison for hours. I prefer the prefix plugged into Aux2 over hicap DR alone with SCDR on 282. To keep box count down the HCDR will gone.
