HDX/DAC/555PS - I'm exhausted!

Posted by: gone on 09 February 2010

A furtive meeting at Rothersthorpe Services bagged me a DAC on Friday night - couldn't wait to get it home. A bit of cable reorganisation and it's ready to go - couldn't resist a quick listen before bed. Blimey, a very different presentation - even Signora Nero commented on the striking difference. Went to bed with the same excitement as a child on Christmas Eve.
Had some time on Saturday for a good session and also rearranged and optimised the cables - note to Naim - there's only a very small clearance between the Burndy and the Fraim with the DAC. Getting the HiLine and Burndy to relax and forget their last comfortable shapes is a pain but worth it.
Spent the next few hours deciding if this was a step forward. Not at all sure. Loads of detail, more bass than I'm used to, but an amazing imaging - not used to that either. More hi-fi?
But slowly I realised what was happening - the old cliche of 'hearing things I've not heard before' came to mind but there was more to it than that. It was the interest factor - my attention was drawn to things happening way down in the mix, and presenting things with a different balance.
But above all, it was the speed things were happening. Graceland was coming at me like Paul Simon had been drinking Red Bull, Modern Times made me want to dance and sing along with Bob - never done that before.
Came back to it on Sunday night - different again. Is this what people mean by 'burn-in'? Not been convinced about that before, but here was proof? Much more laid-back presentation today, but still the way my attention was grabbed is remarkable. For example, on Wish You Were Here, at the end of track 1 when the manic saxophone fades away in the background, I found myself hooked and following the sax playing, rather than noticing the crescendo of the machine throbbing.
Last night, much more settled - I'm really loving this, and tonight, it's truly excellent. <hyperbole alert> Streets ahead of HDX/555PS - this is way out there as a digital source. I've no idea if it's better than a CD555, as mine left home some time ago, but I've got a good feeling. Goosebumps on music where it's never happened before, and the timing is brilliant - I can hear backing musicians having fun.
Exhausted? I'll say. I've just been dragged around the floor by Steve Hackett.
Tried some hi-def tonight - stop press, Robert Plant can actually sing.
I have a feeling more is to come, but so far the results are, shall we say, positive.
Summary - great imaging (ooer), very detailed, very linear (digs out stuff in the background), very tight and well-timed (I guess that's the 555PS). But I reckon it keeps you fitter than a Wii

Dear Nero,

Enjoy, it will get better - I've had mine for a month and it gets better. Its a pretty serious device. Mine is powered by a XPS2 and fed by a CDX2.2. I'm thinking of getting a 555PS. I have powerlines in the CDX.2 and XPS2 but not on the DAC, how do you have yours set up. Also if you don't mind me asking how have you set yours up on your rack - near brain or brawn stack?

Enjoy.

Dev

Hi Dev
I read your earlier posts with interest - made me feel better about taking a punt on the DAC, despite the puzzling demo I had.
I have PLs on everything - I suspect it's not so important on the HDX (CDX2.2 in your case), why don't you try it and report back?
I have two stacks, with the brawn on the right, with the HDX on top. On the left working up is Radikal, Superline, 552 and LP12 - squeezed the DAC in between the SL and 552, but moved the SL to the left, so it's away from the DAC transformer. It's a rats nest of cabling - I'm sure getting that right pays dividends big time. But it seems right enough at the moment!
One day I'll post a system pic.
If it gets better than this, I can't wait
Cheers

Many thanks for the report. Still waiting for mine but hopefully not too long now. My CDX2 is being modified and I have a Power Line waiting to go on the DAC. I’ll be using the XPS2 off the CDX2. To while away the wait I’ve been thinking about what to play first. The Yes Album was in pole position, but Steve Hackett? Yeah, that’s a good idea. I’m getting all excited now. I hope you’ll continue to give us updates, assuming you can drag yourself away.

We've been playing with computer sources most of the day and nothing we do approaches the HDX as the front man. Best we got from the computer was Wavelab PRO 6/ASIO via a TC+Naim PSC. Wavelab is still clearly better than the free players but once you play the HDX with rips, you can't go back. At this point, you might as well stream with a Sonos as it's a lot closer to a computer with MM/Foobar even in Kernel or ASIO etc. than a computer is to an HDX. I'm actually getting tired of screwing around with computers for playback. Some of the results are OK but it's overall been a losing battle. Frown

Well done Nero! There will be more goosebumps. Big Grin

Thanks for the report John.
I hope HDX + DAC + 555 PS will sound good with a 282/200 as well.
I really can´t wait hearing the goosebumps. Smile

Where did the high res Plant come from?

You can download a 24/96 version of Raising Sand at HDtracks. It's supposed to be for USA only, but paying by Paypal seemed to fix that Cool
It's much better than the 16bit version

Nice. Thank you.

Thanks John ... Think my DAC is now just two days away!

I'm sure it will, and as an aside, we were already using a PC/Wavelab/TC/ASIO combo 2 years ago. Good things stay good and preferences for specific kit aside, much of what I've said from day one on this board about computer configurations has proven true. You can probably substitute MAC/Amarra for PC/Wavelab in the above configuration but at the end of the day, they're not substitutes for an HDX in this arrangement.

We were just comparing the American and German ECM releases of some Garbarek rips (have to change the title on one to get the second in)and it was like the good old days of vinyl where differences were quite large and you'd source from the origins country for the best rendition. Smile

It does and my reference is to HDX dig out into this DAC only. Glad your's finally showed up and is working so well for you. Smile We have been doing all our listening via the 555ps and through 500 kit so yes, we're cheating. Big Grin

IMO neither HDX nor PC/Mac based solutions are the ideal partners for the Naim DAC. Sure the former can output great bits but I think you are paying too much only for using it as a transport. Computers are also capable of being excellent transports but it is a pain to mess with them and the vast amount of devices and setups. That's my conclusion after nearly two years testing different setups. I currently use a heavily tweaked silent PC (windows 7/wasapi/lynx AES16/JRMC14) and I would say it gives me top convenience and excellent digital output but I still believe a pure high end streamer could easily beat that.
I agree with those who think the ideal setup would be an air streamer + Nas/Server/Computer for ripping and storing libraries. This approach has the main advantage of isolating completely the player from the noisy (acoustically and electrically) computer-ripper.

I'm with you Goldfinch except that the internal HDX drive is tops of any method tried. We haven't ripped to a closed NAS setup yet so maybe that will be there or close. As I stated earlier, the streamers (so far)were closer to a well setup computer arrangement then they were to the HDX. Streaming through an HDX has been better than the PC outs also but not as good as it's internal drive. I beginning to think there was a method to this madness. I also want to reiterate that better doesn't mean another method isn't worthwhile. Far from it. Price, use and whatever brings you pleasure are strong factors when deciding what to buy. Forums tend to be about all or nothing and there isn't enough room for preference. When I post as with others it's always an opinion regardless of how informed.

Isn't the HDX based on PC architecture (itx motherboard)? Assuming that's true, thus Naim made and excellent job making a noisy computer environment sound so well. I don't doubt it but I still wonder if a streamer device without moving parts, EMI/RFI free would offer better performance.
See for instance the CMP2 proyect people, such a big effort for transforming a computer in a top digital transport, hundreds of software and hardware mods... wouldn't a transporter or the forthcoming Touch plus a Nas offer better digital output potential and a more elegant solution? Just a thought,

Well, lots of things are very similar in bits but quite different in quality of performance. Cost effective varies for the individual. I've still not heard a stream or attached storage sound as good as the inboard drive. Differences may not be huge though can be significant depending on associated setup but if we're going here, those are my observations so far. We'll set up a more dedicated NAS at some point to see if that helps.

I just listened to "Two Against Nature". I'll have to go and have a little lie-down now. This gets better and better

My DAC is at the dealers but my modified CXD2 isn't. Oh the agony.
Posted on: 12 February 2010 by Harry
Looks like I'll be up and running on Tuesday. I won't post a review in your thread but it will be interesting to read your accounts of where I am likely to be a week hence. If that makes sense.

Hola Jose

I have had this argument many times. The HDX/NS servers are NOT computers. The disk drives they use are NOT available through computer stores, they are specific models for this type of application, quieter, slower spin speed etc.

I had a guy here who told me his local computer store sourced all the Naim HDX components, including the drive ans CD ROM and put them into a fancy expensive computer box. How wrong he was when he told me the component model numbers, completely wrong!

You know what? He now phones me asking if I can install the Naim ripping software on his machine so it can be an " HDX ".

Now how stupid is that? This why the HDX/NS is a product NOT a computer. Also, try placing a computer on your hifi rack.

Not everbody is comfortable using a computer for CD storage, navigation and playback. The Naim solution does it all for you and they support the product not some small computer store who will probably be out of business when you really need support.

Everybody has a choice but make no mistake, the Naim solution is first class

Un saludo

Gordon

Yes it is. Smile Some of us are comfortable using computers but came to the same conclusion as Gordon after trying LOTS of variables comparing dig out. Computer results can get good but never as good and for it to get good, the convenience factor low. Unlike most, I could live with that if the performance was matched but it isn't. Streaming seems a better and more user friendly option for consumers but nothing has streamed as well as our HDX either and even that hasn't been as good as rips via it's own internal drive. You need a good 24/96 file to beat an internal 16 bit rip.
Posted on: 12 February 2010 by Joe Bibb
js,

What evidence is there for the HDX performing better rips than you can achieve with a computer (which is all the HDX is)?

Other than your subjective opinion and commercial incentive, that is.

You keep repeating this, obviously hoping that it will become accepted as fact, which it most certainly is not.

It is not in Raid.

The main drive's content is copied to the back-up drive but the drives are not in traditional Raid 1 configuration.
