To dac or not to dac - that is the question.

Posted by: church warden on 23 June 2009

My current set up comprises:

cdx2/xps2/hiline/202/150/fc2/Neat Motive 2. The Motive 2s are a fairly recent addition (replacing longstanding IBLs) with Chord Epic subsequently replacing NACA5, and 2 powerlines being added from a one off addition to my funds. I am not a regular, or big upgrader. I know my system has its limitations but I enjoy listening to the music it produces and affording the next significant level up is not a realistic prospect.

Having too much time on my hands, gradually I have been building up a lossless (EAC FLAC) back-up of all of my cds (in fact, two back-ups stored on separate portable drives). Irked by a comment from my partner about how much nicer it would be if she could just use Songbird to select and control the music going to the Naim, I am wondering whether the time has yet arrived when a computer/DAC combination can truly, significantly out-perform my cdx2/xps2 combination at a similar or lesser cost.

I don't wish to stir up the fundamentalists of which, from a study of other postings on this forum, there are clearly a few. I am seeking some reasoned, considered thoughts on what, if any, DAC options there may be which would warrant my consideration/auditioning for replacing the CDP end of my system to give a genuine improvement in the musicality/quality and provide my partner her "user friendly" interface.

Very similar to my own experience. I ripped using ALAC (controversial) and am using Apple TV with TOSLINK into the cheap but decent Beresford. The rest of the kit is 252/140/pro-ac 1SC. Comparison is vs CDS2 with recapped PS. I don't ask the Apple TV to do anything else except this.

It is very hard to tell them apart, really very hard. The one thing I notice is that on a long listen the apple tv/Beresford DAC combo is a bit more fatiguing. I think this is some treble hash. It may be because I ripped using a not very good portable bay. Am going to buy a better one and rip all over again.

For me the work of ripping is worth the ease of playing. I use a remote application on the ipod touch to control the apple tv. So, I sit in the kitchen flipping through the library, pick my music and then head into the living room to listen. I even use it to control volume (the equipment is all hidden behind large doors. I have also been surprised by how much I like Genius and how this brings songs together in a way that is fresh and makes me listen to stuff I forgot I had. I know there is lots to be said against Apple but they make somethings very easy and for me that is worth a lot.

Cheers

555ps changes the game again for all the Naim bits and I suspect also for the DAC though it will have to be great on it's own to really become a force. I suspect a 555ps may have helped the earlier comparison but there's certainly no comparison in price. The Weiss is definitely cost effective until something better comes along. Winker Good to do these things for yourself and decide. Smile The only other I'd currently try in that range is the Nagra LB as a DAC with a TC interface. Not as easy to use or setup but I like it. Of course the similarly priced Naim DAC isn't far off either.

Nice to hear that Amarra seems to be the real deal.

Yes I've heard others make mention of it and Daniel Weiss obviously endorses it.

I see you can 30 day trial it - what does it actually do? Anything that Apple themselves won't do or some open source geeks at some point?

All,

The free trial only lets you listen to a part of a song.

The 30 day "Full" trial eliminates the silence, but costs $50 and is only refundable with the full purchase.

There is a "mini" version now as well. Not sure about anything concering it.

Joe,

Apparently standard iTunes on a non-Snow Leopard OS is extremely compromised. It could be buckets full of jitter, non-bit transparent, resampled, EQ'd or something. But there MUST be something really wrong with it.

If Amarra and Snow Leopard can bring HUGE, and i mean HUUUUGE improvements to what was already considered perfect replay, there must be something seriously wrong with bare iTunes on a OS X Mac.

If we are not to attribute these improvements to placebo/imagination, the ONLY answer is that the old OS and the ways iTunes is output were laden with jitter. It is the only explanation.

That being said, they must reduce jitter somehow.

Patrick,

I know what you are saying, but PCs (with appropriate cards or bypass software) and Intel OSX Macs have moved enough people away from CD already. Not everyone but the numbers are very significant.

The fact that improvements continue to be made should be no real surprise - presumably that's what advances in CDPs were sold on too. Nobody used to moan that their previous player was not as good as it should have been. Winker They just accept the progress - or not. After all if we get hung up on the 'perfect' bit - that was CD's slogan in the early 80's - "perfect sound forever" - yeah right. Big Grin

I think the jitter thing may be part of it but the encouraging thing is that my computer audio was already ahead of where my CDP had been, for much less. So if there is more to be had....no problem.

I interviewed a former record company senior exec today. We got onto the subject of sound quality "so do you notice a difference with MP3" really??!! well you must be in the .0001% minority then... arrrg this is the head of a record label Eek

Patrick, you are forgetting that Amarra is NOT bit perfect so any "superiority" is subjective. Acc to Benchmark, QuickTime resamples so the new version with snow leopard might do that better.

Or it might just be placebo.

Where did you get that info ?

I used to be an analogue junkie before but after playing around with Mac/Dac, I think that there is no way for me to go back. Sonically, I think that there is nothing that can beat a good vinyl setup but the conveniences and potentials of a PC/Mac+DAC are so great that I am prepared to sacrifice some losses in the music reproduction.
