272 finally arrived

Doh! photo won't appear.

Thanks James

Not sure why I couldn't do this. Not sure which link to have used from Photobucket.

Just awaiting the abuse for sitting 272 on a rocking coffee table. 

Hi Dougie - In Photobucket, copy the IMG text (from the share section) and you have this -

Select the text i've highlighted in bold (between the IMG tags) and put that into the source section in the insert image pop up (click on the little mountain range photo to get this).

No worries - lightweight coffee tables are good 

Looks like a fantastic one box solution to me. Congrats and well done.

So frustrated that I ordered a new 272 and 250DR way before christmas and it arrived last week whilst my HiFi is packed away as building work is being done and the house is full of brick dust. I couldn't resist and leave the 272 in its box so I'm using it with headphones. I then decided and surprised myself that the headphone amp within the 272 is good enough for me so I sold the Headline & NASPC which gave me a spare shelf on the Fraim. To add to the frustration I then went out and bought (gulp) an XPS DR this weekend to fill that empty shelf. The new 250DR and XPS DR are still in boxes until building work finished. 

So up to now I have spent loads and still have never heard a 272, 250, XPS.

Looks like an ideal rack to rock, the Fraim on statement level.....

Really liking the headphone amp in the 272. I wonder if the XPS will make it sound even better?

Patience is a virtue.

Think of it this way, the new kit WILL be great and will sound even better in your newly refurbished room. Now chill with the 272 and the 'phones and don't be tempted to unbox anything else until the dust has settled. 

Dougie,

I did this recently with 272, xps dr, 2x 250DR biamped, all stacked in a pile on a rather fragile coffee table. While waiting for the HIFiRacks made to measure podium slimline on order I lay awake at night every night waiting for the crash as gravity grabbed all that weight. The crash never came but the rack eventually did praise the lord :-)  Philip

555dr is not making is sound better! Mojo is ten times better if not 25 times!

Wow! Only 25 times better? I had a Mojo on loan and was disappointed. But then I also had a Hugo on loan and was not overly impressed with that either. Maybe I'm missing something but I'm happy enough. 

The XPS DR makes my 272 sound very significantly better, with a wider and more detailed soundstage. Wondering whether to get the 555ps which, on paper, has a significantly bigger transformer and other say brings further tangible improvement.

Are you the guy with two 250dr's running off a 272?I asked you on another thread about it,but you probably never saw it...anyway,did you compare two 250's to a 300dr,which most people here seem to recommend?.Are your speakers bi-wireable,and you just have them hooked up directly,or is there some kind of crossover you use.I am sure other 272 owners would be interested in your setup/thoughts.

No Quarter - sorry didnt see the other post. Yes, I am. I am a rock/electronic/general fan enjoying the hifi ride. Had Naim for 30 years - most of that time with RP3/Nait2/Rega Ela (wrong speakers for rock lol). Embraced the digital revolution.  Ripped all CDs to Wav/QNAP NAS (make sure you have two in different places for security) and selling them on E**y.  Loving my 272/XPS DR with quite lovely Proac D30r, that also please the wife in their excellent finish and classic looks. They were designed for proper bi amping with twin posts (not biwiring), as are all Proac Response floorstanders. Very convincing bass extension here, and am interested in pursuing this further. I bought 2 x 250DR as I wanted the power and they sell well later. It wasnt my last amp. I dont want to mess about with lots of upgrades so have bought an older 500 which is in the DR queue at the moment. Cannot afford a Statement.  

My Taksims have dual posts too,i am not really sure if they are bi-wireable or bi-ampable,or what the difference is.It just seems to be frowned upon here.Right now i use Naca5 with an "F" connection on the speaker end,and this sounds really good to me,also my speakers are 92 db's efficient,so one 250 is probably plenty,i was just curious about your connections,thanks.

The Proac D30rs are 89db and with vol on '55' (which I use quite a lot) the 250s are in total control and the speakers clearly will take much more. Twin posts, (connecting bars removed) twin NACA5.

The following is an extract from audioholics -

Bi-wiring

In order to bi-wire a speaker, you need 2 separate lengths of 2 conductor cable. Both cables are connected to a single pair of terminals at the amplifier, while at the speaker end you remove the jumper straps and connect one cable to each pair of binding posts. So what difference does it make? In short: “not much”

Bi-amping

Bi-amping involves the use of two separate amplifier channels per speaker, one to connect to each pair of binding posts. From there, we get a few subdivisions: active vs passive, and horizontal vs vertical.

Passive Bi-amping

Passive bi-amping utilizes the passive crossovers built into the speakers, with each amplifier channel reproducing a full range signal to drive separate high and low frequency networks. Relative to active bi-amping, the benefits of passive bi-amping are much less pronounced (you might hear the derogatory term of “fool’s bi-amping” applied). Nonetheless, splitting the high and low frequency networks does have some effect, as the amplifiers each now see a different load than one would under normal circumstances when individually driving the entire speaker. Generally speaking, the individual networks are designed such that “out of band” frequencies will have a very high impedance relative to the expected pass band of the driver(s), and consequently will demand significantly less actual power from the amplifier at those out of band frequencies.

This is what I am currently and temporarily doing

Because of this split, there are a couple practical advantages. Potential output ability is increased as there is little power wasted reproducing those aforementioned “out of band” frequencies. As with active bi-amping, the possibility of tweeter burnout due to amplifier overload is also reduced. However, in terms of basic audible differences, there’s not much to write home about, and what improvements do exist could typically be gained by simply utilizing a single more powerful amplifier with similar or better performance metrics than the two smaller amplifiers.

So are you saying the XPS DR  improves the headphone amp within the 272?

they had a particular sound, sharp on Hugo littler less in mojo but the detail is there.. maybe best selling headphone amps of all times

compare 272 is very 2 dimensional and flat... i tried with hd800, Elear, Fostex th00... all 3 different animals

272 headphone amp is a " free feature " on the main feature and any headphone good dedicated headphone amp will be better in my opinion

believe me i did blind tests with my wife 272 vs creek headphone amp, every time we identify the 272 vs creek, it is that clear even with a easy to drive fostex th00 ( the mass drop one ) 

a 555DR powered 272 by the way
