282 with two Hi-caps?

Yes Ktmax - I know it is not the common opinion but I bought a second hand SuperCap and I found the presentation dull and uninteresting. Then my dealer persuaded me to try with 2 Hicaps and it made all the difference but I guess it is a matter of taste

Henrik,

it sounds to me like that secondhand Supercap was possibly in need of some attention. You should try another one, or  perhaps you already did?

Yes Richard,

Though I was extremely pleased with my 282 with 2 Hicaps I received

an offer for an almost new 252 with a SuperCap DR so I had to go for that.

Henrik

i have two Hicaps and tried using both on my 282. like others, i found no real difference -- so i stuck the second Hicap on my CD5, for the odd occasion when i use it.

I am hoping to join the significant number of people who recommend dedicated mains having had the work done over the weekend. That is seperate consumer unit, 10mm cable to double unswitched sockets. Plaster should be dry enough to start reassembling in a few days. Not sure what to expect so wish me luck.

Just so as not to completly highjack the thread I only had one hc on my 282 but I can very strongly endorse the view that the sc takes everything to a very different place. Picked mine up second hand.

You should be in for a treat!

But do keep in mind that it takes a long time for a spur to break in and sound good. You'll notice the most change and improvement during the first 4/5 days. Then things start to settle down and the changes will be more subtle. So don't be disappointed if it doesn't sound great from the first time you hit the Play button. 

The power draw from a typical hifi system is very low at idle and at normal listening levels. If you want you can speed up the cable break in considerably by running a high power device from the spur. Things like a watercooker (10 runs or so) or an electrical heater for a day. Anything that draws a lot of power really. 

Thanks for the tip. It's that odd combination of excitment and trepidation. Will it be great? Will it be terrible. There have been occasional posts from people who have gone to the trouble to have the work uninstalled for various reasons such as it sounding "too hifi" or it just killed the music. They do seem a minority though. For most it seems the step to take before even contemplating a new black box. I am still going to have my fingers crossed though!

You'll not regret it. When I did mine I was hoping to reduce the various 'pops' and 'clicks' that could be heard through the system from the various switches etc on the household circuit. I got that - completely eliminated them.  What I hadn't expected was an improvement in system performance but it delivered that too. While doing this can be domestically disruptive, in cost terms I think it the best VFM upgrade you can make.

My new room where my setup will be moving to has just been plastered. Will be having a dedicated supply hooked up very soon. I'm looking forward to hearing the improvement this will bring. All nice and ready for a 282 at some point this year! 

I'm currently running a single HC DR on my 282, so will likely eventually swap to a SC DR.  What I'm wondering is what technically makes the SCDR so much better then 2 HCDR's?  We know how much Naim likes to put things in separate boxes, & when comparing cap & transformer size, they look basically the same between the two, so one would think 2 HC's would have the advantage of two boxes, looks about twice the capacitor & transformer size?   The DR boards look basically the same (just the SC having many more, which I would assume would be due to it having additional voltage outputs), though one would guess the SC must use better quality components on these boards/more advanced circuit design? 

I wondered the same thing Daren! 

I think you'll find with two HiCaps the pure star earthing is broken, but is maintained with the SuperCapDR or a single HiCap... therefore the lowlevel noise floor is likely to be increased with the two HiCaps

I also wonder the same thing.

Being an active fan, Im in a perfect situation to evaluate the difference between the HCDR, and the SC or the SCDR.

Of course, the Snaxo could be powered by an HCDR, but to utilize the Burndy a SC would be mandatory!

Hence, my next Black Box upgrade will be a SC, and I can switch monthly within my listening environment to see if I can detect a noticeable difference between the HCDR and SC/SCDR.

Sounds great Simon, I don't know the technical jargon, but two noisey black boxes vs one, I'll take the latter.

Could you comit on the difference between the HCDR and the SC.

For the sake of the Forum,  I already know which one you favor, and the marginal difference.

Now 252/SC vs 252/SCDR that's another story!

But repeat 282/HCDR vs 282/SC

Engineer language please! LOL.....

So with the SuperCap and a single HiCap for a 282, the key difference is that the HiCap shares the positive and negative power supply rails for both channels, with the SuperCap the positive and negative power supply rails are separated for both channels.

Thanks Simon!

I bought a new 282 and 2 x HiCapsDR, the cost was cheaper than a SuperCap by around $3K as I recall. Using my horn speakers I found a real improvement over just  the one, my wife concurred. I have no doubt however the new SuperCap would be even greater, albeit at quite an additional cost. My advice mate, take time, consider what you wish to achieve in the long run. If you visualize yourself upgrading to a 252 down the track, get a S/C so as to avoid $$$ loss later when you desire a 252.

I agree Aussie, and if I recall, Simon agrees.

In fact , para-phrasing " with the 282, I think, the HCDR, is All you need." if I recall correctly.

I remember this vividly, like the OP, I was torn between the SC and HCDR. 

But to your point Aussie, you tried 2 HCDRs, and found an improvement in SQ, despite the pure star earthing being broken.

But with no intention of upgrading to an 252, and a Great DEAL on a HCDR with less than 6 months of use I chose the HCDR.

Mind you, down the road I knew I would have the opportunity to A-B both PSs, being an Active Fan.

But when it's all said, and done:

We spend thousands of dollars for subtle gains, that aren't detectable by the norm.

But Remember, we aren't the Norm LOL!
