Naim NAC-N 272 with 555 PS DR

Happy  New Year friends!

Finally added today a 555 PS DR to 272. As it was stated by some here, it is just another level of everything.

Sure it is the way to go if you can.  Big difference on the streaming side, less on the preamp.

Hope this helps. Enjoy!

It's funny...only a few days ago I tried my 272 with out its xpsdr ... for the first time!

Upon first listening I thought...so what exactly was the xpsdr doing ??? But after a while I realized what I was missing...just a fuller rounder more musical sound...but the bare 272 still sounded nice ...

It is all about more details, bigger and deeper stage, better controlled and faster bass, more natural voices etc, it is hard to define at the end but really easy to hear and feel...

its like with cars - first you buy a car, then you buy a good car, then a nice car, after a fantastic car and you end up buying Ferrari...voila

Congratulations @Tesilk

I’m sat here listening to my bare 272 and it’s sounding fantastic. I’m sure adding a 555 would blow my mind! 

It would / will

I’ve just been listening to Finkfans system and have to agree it’s sounding superb, the newly added GIK panels are worth their weight in gold, amazing what a difference they make, adding the 555 would certainly mean having to invite me round again....

I swapped my XPS DR for a pre-loved 555 PS (non DR) less than a week ago to pair with my 272. This is my first 500 series anything. At first, although I could sense and hear a difference, it took a while for me to truly appreciate just how much better it is in everything. Everything just sounds more relaxed, natural, no hint of any edge and dare I say, in strange way, more analogue. 

Almost a week in and I'm glad I went for it.  Perhaps I just got a glimpse of what a 500 series kit is all about!

Good to hear guys,although one guy that posts here(GRAEMH) went from bare 272,to adding a non DR 555,to an XPSDR...but we have not heard much from him about the XPS.The 555 is a lot of money here in Canada,and I struggle with the decision whether or not to save up for the 555,or for around the same price...a Chord Dave.I can get a demo with the Dave,but not the 555.

I added the 555Dr to my bare272/250DR 6 months ago and it continues to improve even now. I agree with the various descriptions of the music above, and would also add it makes the music more.... translucent. You can really get an appreciation of how the various instruments and voices interplay, the sound-stage is more explicit. It  is almost like you can get up and walk amongst the various performers, the various musical strands  are that clear. It is no longer hifi, it is just music, and I have difficulty walking away from it whenI go to work.

And I am still at work and not smoking any electric puha!

That’s because I’m listening listening listening! Very happy with the new XPSDR over the (2006) 555PS I tried.

Nice to hear,pretty good isn’t it,GRAEMH,I just find it odd that so many people say the 555 is so much better...maybe they are trying to justify the unnecessary money they put out.Keep in mind,I have the XPSDR,but have not heard the 555,I guess it could be speaker dependant,but my special 40s really work well with just the XPS.I bought my new XPS(dealer demo) for 4K (Canadian),and my dealer wants around 14k for the 555DR,so quite a streeeetch.

Huge,that sounds like a really good deal,but that is still over 7 thousand Canadian dollars.Lucky for me,I was the only one to demo the XPSDR  that I have,so really,it was brand new.Over here in Canada,apparently once a year,the dealers are offered a huge discount on Naim gear,so my dealer grabbed a 250DR,and XPSDR...knowing I wanted them.

Okay, here's where I'm at.  I have a 272/250DR combo.  Sounds great.  Knowing that there's always another level of "more" with Naim products, I'm thinking of adding a power supply, either the XPSDR or 555DR.  Or, I might get a new DAC - the Chord Dave.  Which way should I go - power supply or new DAC?  I'd like to do both, but realistically, I'll have to stick with one upgrade at a time.

Getting a new Dac would presumably mean changing pre amps too unless of course you use the Dave as a pre also.  I do understand that you can use a seperate Dac with the 272 but to get the very best from that very expensive Dac I would think that a 282/HCDR would be a minimum and of course you would need to add a streamer.

Why would a separate preamp be required?  I'd connect my Core to the Dave, then RCA output from the Dave into the 272 analogue input.  Shouldn't that work for playback from the Core?

It would work fine. I think the point is more about redundancy - or choosing the most appropriate gear for the job. Going for Core - DAC - 272 makes it nothing more than an analogue preamp, with the entire streamer - DAC section unused, so it might be logical to put your resources into a dedicated preamp instead of the 272. Of course, if you already have the 272......

Am I right that you have the 272 sitting on the 250? If so where would the extra boxes go. I’d get the existing kit set up properly first. And if I’m wrong, please ignore that question. 

Hi HH - yes, I have my 272 sitting on top of the 250DR.  No other place to put it.  Due to space constraints I can't fit in a Fraim.  However, I have placed 4 Silent Feet (made in Germany by a company called Thixar) between the two boxes in an effort to isolate them.  If I get a PSU I will get 4 more of the feet.

Have you thought about some shelves to put on the wall? I’d suggest that the negative impact of having the boxes really close together won’t be overcome by fancy feet. You’d be much better getting the best from what you have, rather than spending even more. Wise man builds his house on rock and all that.

Quite - sticking a 555PS into that pile (with its honking great transformer) certainly won't get the best from the kit.

Sticks of rock as piles for the foundations, gingerbread walls... etc.?

Unfortunately there is a window behind my setup - can’t do shelves.  So, it’s stack them or nothing.  The only thing that I can do is isolate all of them from each other.  At least I’m going to try.

My perception of this issue (which could be entirely incorrect!!) is that there are two issues to consider:

1) Physical decoupling of each component from any source of (microphonic?) vibration from speakers, other black boxes, etc. A good rack should help, but if you can't accommodate one, Fraim style glass on ball bearings/cups might still help.

2) Distance between sensitive source components and powerful electrical currents, such as AC supply cables and large transformers. The latter become bigger, and potentially more problematic, as on progresses up the Naim ladder, so a preamp might suffer more from being close to a 555 than an XPS, and more from being close to a NAP300 than a NAP200, for example. 

Can anybody think of a shelf or component stand/device that would provide isolation from the transformer in the 555?  Or is this something that can be achieved only through physical distance between the two, e.g., the 555 and a 250DR, or the 555 and 272?

My Naim equipment is on a computer desk in my kitchen.  My main system is in my living room and consists of an audio rack on which sit a Burmester 082 integrated amp, an EMM Labs CD/SACD player, and soon to be an NDX.  I have Proac Response D80 speakers. Lately I spend a lot of my time at the computer.  I wanted a high-end system in the room, hence the Naim Gear.  I have Burmester B10 speakers.  I want to have even better sound than I'm getting, so I'm looking at a power supply upgrade.  I simply cannot fit in a stack of Fraim, as much as I'd like to.  Unless I completely move everything, which I don't want to do, I'm stuck with this limited space.  If I can't stack them, then perhaps I should just get rid of everything and try another manufacturer.  However, I'd much rather stick with Naim...  .  ,. .

I don't want a headphone rig, and wouldn't consider it unless I did a lot of computer audiophile stuff.  I don't.  I have over 2500 CDs & downloads on my Core, which I play back through the 272.  My Burmester speakers sound wonderful and as far as I know are better than a set of active speakers, no offence.  I want my system to stay as it is, i.e., a Naim system, but want to improve on it.  My dealer doesn't think stacking Naim boxes is quite as horrible a thing to do as others - then again, he IS trying to sell me a 555PS.  I will do my best to physically isolate the components.  The Silent Feet (Thixar) should help to mechanically decouple them and prevent vibration.  The 272 will sit at least 7-8 inches away from the massive transformer in the 555.  We'll see how things will sound.

Hi No Quarter - no, I haven't given it up entirely yet.  I'm still trying to sort through what my next move should be.  I can't do both at once. It sounds like the power supply could be a problem, especially given the size of the 555 transformer & the proximity of the 272.  Maybe I should go for the Dave. I can always get a PSU when I have more room to work with.
