Supercap DR losing vs Hi Cap DR

Agreed. If the HCDR is making your ears bleed there is an underlying issue that the SCDR won't solve in the long term. The SC is a short term bandage that won't ultimately resolve the issue.

In fact, spend some time with the SCDR and I suspect the same issues you have with the HCDR will manifest themselves, albeit to a lesser degree.

Eagle, Burn in of new kit can take months. The last thing to "come right" I find is the top end. If the system is burning in then it should get much better over the first six weeks. The problem you have with top end may well be effected also by the mains. When I first connected my system to a dedicated radial the effect was massive. One of the first things I noticed was that the top end shreik had disappeared. By far, the worst my system ever sounded was when it was plugged into a trailing multi socket extension lead. Food for thought!

John just sumed it up, if things havn't settled in, within a reasonable period, have the dealer drop bye, and analyze your listening enviroment.

That is what I am finding out with my new 250 DR. The top end is taking time.... bass has been ok from day 1.

And I agree this seems to be a slow and gradual process over months.

Dare I suggest a non-DS Supercap might just give you the balance you desire?

G - this had occurred to me to!!!! Has the DR upgrade made the sound a bit harder? However : UPDATE :

In desperation, I put the A5 cable back in and gave it more than a cursory 5 minutes trial. Holy cow - the overly bright top end obvious in the HC and detectable in the SC left the building. Thank gawd for that. I was on the brink of selling-up and moving. HC is now like the sound I'm used to, but more revealing. SC is still super extended in mid range and bass but vocals are a bit less recessed; jolly good. Biggest change, though, is the SC sound has taken on a gorgeous rhythm. It doesn't quite have the pace and excitement of the HC - Rodrigo & Gabriel's tortured, raucous guitars are rendered warm and sensible - but it has something that makes the sound kind of calming. Beethoven's 14th slow piano movement is luxurious and liquid. Tightness of detail in P Gabriel's San Jacinto is incredible. Must be the warmth the SC brings. Almost analogue - exactly as someone else above said. 

I could, now, happily live with both, for different reasons. The HC maximises the thrill/speed factor; the SC is a bit calmer - more 'grown up', also exactly as someone else above very well put it. It also feels like the SC sound has got a lot more to give whereas the HC sound feels like it's gone as far as it can go. (This might be complete cobblers, of course.) 

Verdict: I'm now going to stick with the SC. After listening for a while and going back to HC, I missed the giant soundstage even if it was at the cost of some attack and thrill factor. (Bummer about Rod' & Gab' though!) I'll spend time luxuriating in its super smooth rhythms and, if I still feel the same in a few months, look to inject some of that missing pace without losing the huge stage.

Thanks to everyone who has contributed help and advice. I reached a point where I didn't think I'd be writing the happy ending that many people manage to reach! You've all been a great support. What a difference a bit of old wire can make!

Curios, what Speaker Cable were you before the switch?

I couldn't find it in the post, getting old!

It was 25 yr old Linn. Very big, black, heavy, plugged for bi wire. Looks like K400.. Old - me too; thinking of a hearing test next!

You're ok, funny thing, I just sold a 8 ft pair of Linn K 600.  Very rare bird, Tri Wire application I used to use with my Full Blown Linn Aktiv System. Lp 12 > Karin > Linn XO with Bingo Card and Dirak PS > 3 x LK 282's > Briks! Brings Back memories!

Glad you got things sorted out, Keeps me on the right track, Thanks.

It just seemed so natural and logical for the 282 to benefit from the dual railings, allowing for two HC's or  an SC. 

Enjoy your Music! 

Out! 

The Armchair QB!!!!!!!

I started out with Linn 30 years ago but never to that level! Stunning. Happy days nonetheless! Cheers and same to all! 

All the best!

Music is what all this is about 

Especially the clean VW diesels

Another thing to consider when upping the detail-recovery with better supplies is making sure you have them on good supporting HiFi shelves, such as Fraim.
The Supercap should end-up being a lot better than the HiCap, but sometimes less can be more when there is an issue elsewhere in the system. The more I have spent on expensive supplies over the years, the more they demand being installed well to really give their best.

Good that you are having success now though!

Hmm - this isn't over. On describing the dropped pace/excitement but otherwise contentment and final decision to stay with his ex-demo' SC and send him the HC in p/ex', my absolutely brilliant dealer told me he'd prefer to have the SC collected and check it before we go any further. In this often dodgy world, I'm deeply impressed. I'll report back once he's checked it over..

Impressive indeed. All Naim dealers should check their kit out if there is some doubt it is performing correctly.

What's in it for the dealer? Well presumably this dealer will ultimately provide you with a power supply you are happy with. You will be delighted and the dealer will have you as a customer for life. 

That is how it should work. Certainly how it works with me and my excellent Naim dealer (Tom Tom Audio).

For what it is worth I went from a Hicap (non DR) to a SupercapDR and loved this upgrade with the 282. I can't comment on how a SupercapDR compares with a HicapDR with a 282 as I have never owned a HicapDR.

Good luck, I think you will (eventually) be delighted with either of these fine power supplies.
