Blimey, the 272 is even better than I thought it was...

Posted by: hungryhalibut on 19 October 2017

I’ve been using my beloved 272 since June 2015, with the addition of an XPSDR in autumn that year. Yesterday I installed a brand new 555 PS DR, with a new S-XPS Burndy. Rather like when I bought the XPS two years ago I didn’t try the 555 first, and when I picked it up from the shop Dan from Naim was there for a Uniti open day. All Dan said was ‘you’ll love it, even straight out of the box’. And he was right, and then some. I thought the system was sounding great before, but the 555 has moved it to a different level. The music is so much more real, leaping out of the speakers in a much more lifelike way. Everything is clearer, so you get more into the music. The speakers sound a lot bigger too, which I imagine is the impact of the power supply on the preamp. Five hours later to was sounding better still, and of course things will improve further over the coming weeks.

It’s bloody expensive, it weighs a ton, but blimey it’s good. The idea of a £6,500 power supply on a £3,500 streaming preamp is perhaps bit odd, but the combination is just incredible. I know there are a few others using this combination, and that they have said how much better the 555 makes the 272, and perhaps I underestimated how much difference it would make: now I have one at home I am very much over rather than underwhelmed, which is always good.

I've been to Milano loadza times, & I mean years of loadza times,  I love all things diesel, including jeans,  I even been a member of the labour party during my misguided & very misspent yoof,  I grow my own & love any & all veggies, but not exclusively, my own slow-slow roasted garlic infused shoulder of lamb can turn any veggie carnivorous & I too have wrapped chips in The Guardian;   but I draw the line at The Smiths,  I can't risk another manic depression  ..............  I'll get me coat on the way out  ...............

Sadly (or happily?) I don't meet these criteria. Perhaps being a gender fluid Robert Mugabe supporter will improve my chances of selection?

PS I admire your non-PC style. Ever thought of running for President?

It’s a joke at my own expense, based on topics from earlier in the thread and the fact that I am a pretty stereotypical Guardian reader. If I selected out friends based on wanting then to only like what I like, I’d have no friends. Let’s move on.

Moderator,

Whilst we are happy to put up with he ramblings of an old man. We should be subjected to his Political persuasion.

I imagine it might be a very challenging get together if everyone attending ticked all of HH's boxes!

Despite being a Guardian reader (a subscriber even) and an occasional visitor to Milan, I do not own any Diesel jeans and anyway I was working yesterday evening and so missed the invitation window.  So even though I would like to have joined in, I will just wait to hear report-backs in due course. I hope it all goes well.

best

Yes, let's move on. I am looking forward to seeing Rhiannon Giddens performing in Manchester tonight - highly recommended if you've not heard her. This is much more interesting and enjoyable than watching black boxes being assembled. Albeit I have been a Guardian reader for 40+ years..........

David, you are already on the list, should it actually go ahead.

Good grief, can’t you just take it as a joke? There are people on here who like Emerson, Lake and Palmer, and I don’t call for moderation when they are mentioned. And as for ‘he ramblings of an old man’ (sic), that’s just bloody rude and rather offensive. Shall I call for the Moderator?

When a list of inclusion criteria are provided, there's always the question of how the list is is to be applied...

Any Criterion (OR operator)
All Criteria (AND operator)

Or to be perverse:  One and only one criterion (Exclusive OR operator)

This seems to be way over subscribed and as I said in my post above I would be willing to step down for a more deserving forumite (hating prog and Smiths is the real reason). 

So in spite of being to the left of Jeremy Corbin  and a vegetarian I hereby relinquish my place and will undertake to organise some type of Forum gathering in Bristol at around the time of the Show in February and will endeavour to involve Naim as they are always there in force. I'll start a thread nearer the time.

I'm here. I'm not quite sure what is meant by "he ramblings" or why we should be subjected to political persuasion but I'm generally working on the assumption that all is being said on here currently as  excited "banter" in a light hearted manner.

hows that list coming along?

Anyway, back on a subject at least related to of the quality of the 272/555DR + 300DR:  I've just replaced my interconnect cables with a pair of cables made from Mogami W2497...

The new ones are a considerable upgrade on the stock cables, quite a few "I never heard that before." moments.  Compared to the stock cables, I'd rate the upgrade as about 1/3 to 1/2 of the upgrade from a bare 272 to the 272/555DR.  Not bad for £23.35!

Ok, that’s more than enough. The list is closed. I’ll stop there and work it all out with Trevor. Please don’t expect to hear anything for a while!! I may have to resort to the ‘anyone who likes prog or dislikes The Smiths’ sorting system. 

I was just writing in an email to my friend Trickydickie that the new system is just so much better than the previous one. It’s just so much more musical, it’s like it isn’t there anymore. That may sound silly, but I can’t think of a better description. 

I really like the idea of a demonstration that goes from 272/555/300 to NDS/552/500 to NDS/Statement. I’ve not heard Statement before to that would be really interesting, so long as Naim are willing to use decent speakers, and not Sopras. 

I’m on the case. 

They are decent speakers - I live with Sopra 2s every day and can vouch that but of course you are entitled to your opinion -  but only if you've given them a fair audition as I did before buying. They obviously need a reasonably sized room to work at their best.

Of course if they still have a pair in the factory, the Ovator S800s could be interesting with the Statements. My dealer has the same setup at home and got one of the last pairs out of the factory - lucky man!

That would not be bad at all, especially if one could say that the XPS does about half what the 555 achieves. I’m not sure how I’d rank what the SL achieves in terms of proportions, in fact I find it really hard to objectivise the subjective in this way. Whatever, they certainly seem most successful. Bargain!

Posted on: 23 November 2017 by Huge

Yes comparison to the SL would be interesting; I strongly suspect the SL would win, but not in ratio to the price difference!


In respect of providing ratiometric assessment of subjective differences, yes it's not an easy thing and very variable person to person, so individual opinions are of very limited value.

The only way to get truly reliable results is to use a large panel of people (>10), get them to undergo a set of calibration exercises first (using fixed comparison points) then repeat the assessment of the unknowns multiple times.

Far too much pfaf for HiFi, at least outside of dedicated companies like Naim!

Might I suggest that, whatever efforts you make to put these comparisons onto a pseudo-scientific basis, the moment you transfer from the listening room to the individual's home all bets are off!

I worked in market research for 12 years, mostly in the field of customer satisfaction. Quantitative research techniques are applied to the objective assessments of subjective topics as a matter of course and this provides reliable comparative assessments as long as certain statistical rules are obeyed, particularly the randomness, representivity and size of your sample.

Not sure any hifi manufacturer would be prepared to pay for the rather expensive quantitative research projects I used to run.

Geez, it has all come flooding back.

I have just realised I am again guilty of perpetuating thread diversion - apologies.

As punishment, I will report back on my findings from the home demo of the 555DR I have lined up.

Posted on: 23 November 2017 by Huge

Relying on randomization requires very much larger numbers of test subjects.

Posted on: 23 November 2017 by hungryhalibut

This all reminds me of my PhD, doing seemingly endless repetitions of foraging tests, sitting in near darkness watching fish under infra red light. Then there was the analysis, mainly regression and correlation, which seemed to take ages back then, when jobs were submitted and ran overnight, coming back on yards of green and white printout. Tonight I’m off to a talk by the captain of the Sir David Attenborough, the Antarctic research vessel that nearly got called Boaty McBoatface. And there is a beer break halfway through.

In my case it was counting barnacles on rocks to asses the spread of Elminius modestus.

I quit master of musicology after half a year because of these kind of assignments and even more because of the boring fellow students. Total absense of humour, way too serious. Certain people really take these scientific assignments serious.

Returned to my job.

Fascinating. Another zoologist, and a fellow 272/555/300 owner as well. Australia to Britain is a long way for a little crustacean.
