555PS DR upgrade have bitten bullet

Richieroo posted:

Hi all have just taken my PSU for a mega upgrade ......... I hope ... It will deliver ..... 

Itchy fingers aka upgradis? It is often accompanied by the immediate depletion of funds for an often short-lived 'high' before another 'hit' is required to satiate another 'curiosity'. Welcome to upgradis 'anonymous': one may 'leave' whenever one chooses but one is always welcome 'back'.

Richie - having just pressed go for a SC and having the HC for my SL DR’d the “final piece” will be sourcing a 555DR for my CDS3.   

All the best - enjoy the music when it comes back.

Lindsay ......... when I fitted the 555ps to the 272 it made an enormous improvement - I think my words were 'Holy Bleep' .... followed by a huge grin ...... and a mammoth listening session........ I would think the already excellent CDS3 would be lifted by a very satisfying amount ........ there are SH 555 psu's around for some reasonable money....

its certainly on my list for my NDX, might be alone but thought XPSDR was not a huge improvement over the bare NDX -

add in a 555 totally different matter,  but just my budget has been spent this year on my LP12 upgrade

One or two Hicaps on the 282 and sc on the superline?. I know that’s not your plan but if you’re tempted to give this a try borrow the right Burndy as a Snaic just doesn’t do it justice. Supercap and Snaxo use the same I believe.

No I’m having a HCDR on the SL and SC on the 282 - that way all 3 source components benefit.

I had the same idea but when I transfered the supercap to the superline I realised what I’d been missing. I didn’t do this until after the 552 however.

Anyway this is a 555ps thread, I also have a pre DR one which is around 9 years old. I thought I’d wait and compare it to a DR one when the 555 streamer comes out. At 3 1/2k for a service and doctoring it might have to wait anyway.

I have a non DR 555PS powering digital side on NDS. Contemplating benefit of DR ing this and service as it’s 10yr old. I have 555PSDR powering  analogue side of NDS. 

I always assumed the double 5555 on NDS had to be matched I.e. both Dr or not - is that not the case?

What is the current cost for DR & service  for a 555?

Same here but only 6yr old. Wondering if there is any reasonable benefit to change it to DR version?

Hi all thanks for comments........

Just  a question Ayisgroovy .......... if the NDS can be powered by an XPS and a single burndy ........ it leads me to think that there is some form of common connection between the 2 power sockets on the NDS .......... this being the case .... when you use 2 x 555 ps .......... what is happening??? in particular in your case do you end up with a DR supply being buddied up and electrically connected to a non  DR supply???? Obviously you appear to have done the logical thing regarding the supplying the analogue side with the DR 555. .... and you can obviously hear an improvement ........ I just wondered what the psu pathways are........... can anyone clarify this...........

That's why you have a link plug into Burndy Input 2 on the NDS when using a single supply - some of the power supply rails are shared.  When you use the full fat, 2 burndy supply , the rails are fully split.

PS - See the NDS white paper here - it shows how the rails are split when using an XPS and a 555PS supply.

Thanks James ........ now I understand ........ cheers. 

The upgraded 555psdr has landed! (hopefully without nerve agent contamination ..... ulp ) I will let it bake for a while and feed back ..... I don't know if my nerves will stand it......

Hi Richieroo - fabulous, please do post your findings on the DR upgrade compared to before!

Congratulations, let’s hope it delivers....

All installed .... however whole system stone cold.....even so I can detect more detail....and a wider sound stage......but early days yet will feed back in around a week....

That’s good to hear, I’m sure it will just get better and better.... enjoy 

Everything has been powered up now for around 5 days ...... so far more:-  detail, openness,  apparent and top end even more refined.... the effect is like a relaxed effortlessness.....  The above is not an epic difference over the 555ps .... but so far a worthwhile improvement is definitely there ..... and will possibly improve yet more.... I am very pleased so far.... will keep you posted in  a couple of weeks....

Nice one Richieroo. I borrowed a 555DR and 552DR supply for my 555CD and 552 and was very impressed with that new level of realism I gained! This prompted me to think about the best DR step and decided that I had to have my 500 done first. Now I'm eagerly awaiting it's return!

Oooh...I've just noticed on 'Hi-fi for Sale' that there's a full Statement up for grabs! Maybe I shouldn't have been so hasty! That looks to be a saving of £50k off the new price! Some lucky blighter's going to get a bargain!

Drool...

Cripes your not kidding!!!!!????????.....i am afraid that's a lottery ticket job.....holy smoke.... The guy I bought the 552 from bought an S1 preamp .... he reckoned that was the most influential part of that kit.....a big improvement on 552....

I've been lucky enough to hear a Statement in a domestic setting with 800's and it completely changed my perception of recorded music. There was information that was being reproduced that the 552 completely misses. The system not only reproduces music it seemed to reveal the micro acoustics of the recorded venue. This is to such a degree that you'd swear you were there, right down to the seat and row number!

Stop it.... this is too much????????!!!

Wouldn’t it be cheaper to buy an orchestra/string quartet/jazz band or rock group? 

Actually you are not far off the truth there!!!!!!
