Octave Mini Projects

Digital Signal Processing Projects is a vital branch for electronics students. Also, it is evolving on other streams of students. Digital signal processing can just refer to as DSP. It is a central area in digital technology, such as wireless and digital communication. DSP is an arithmetical operation for signals at fixed time intervals. It can run any task on a signal such as Hardware and Software.

Product: Octave DAC
Manufacturer: Metrum Acoustics - The Netherlands
Cost: 795 Euros, factory direct
Reviewer: Maarten van Casteren - TNT UK

Some products are more inspiring than others and for non-audiophilesit can be a little bit difficult to understand our enthusiasm forequipment that only looks just like a box to anybody else. DACs areparticularly uninteresting to most people, even if they look expensivewith buttons and little shiny lights at the front. Even messages thatjitter has been reduced to the absolute minimum through innovativereclocking, or that some kind of special filter has been applied arenow so commonplace that you don't really score many brownie pointswith them anymore. For that reason I was very interested in the MetrumAcoustics Octave DAC, as that really does use some new technology.

At first sight there's nothing special about the Octave DAC, exceptfor the fact that it is very small, and consists of two boxes. One boxcontains the actual DAC, and the other one houses the power supply.Even together these are much smaller than most other dacs on themarket and very easy to accommodate. The casing is fairly standard andthe connections at the back are limited to optical or coaxial spdifinput and phono output. There's no USB input, no balanced output andno settings for sample rate or filters at all. The only switches arethe on/off switch and the one that selects optical or coaxial input.That's it.

The interesting story starts inside. This DAC doesn't do any upsamplingor oversampling, hence the NOS in its name for Non Over Sampling, and noanti-alias filtering either which is not that unusual, to be honest.But it also doesn't have an output stage, which is quite unique as faras I know. Basically, the digital signal goes straight into the DAC chips,and then from there straight to the output connectors. No messing aboutwith sample rate converters, complicated filters and fancy output stageshere. If you like your DACs straight and simple, then nothing will beat this.

There's a little more to it, obviously. You cannot do this with anyold DAC chip, and the ones used in the Octave are completely unique,for audio applications that is. The DAC chips are actually notintended for audio at all, but for much higher frequency applications.Metrum Acoustics uses this in more DACs, with the simplest version,the miniDAC Duo, using one DAC chip per channel. Then there's a betterversion, the Quad, which uses 2 chips per channel, and finally there'sthe Octave, with 4 DAC chips per channel. There's also a progressionof power supplies, with the simpler models using basic wall mountedpower supplies and the Octave using a more powerful and higher qualitysolution in a separate case.

In use, I had no issues with the Octave at all. It always behaveditself, whatever the source or the circumstances. It's simple, butalso extremely reliable and robust. I have to admit that my firstimpression was that it was perhaps a bit too basic, but Isoon learned to appreciate the qualities of the Octave as it's such asolid performer. There's something to be said for keeping thingssimple, after all, and DACs rarely come in a more simple form than theOctave.

The sound

This DAC immediately makes a good impression. The sound is warm,focussed, clean and basically without any obvious flaws. It's a veryeasy DAC to listen to, and also one that never pushes you in one oranother musical direction: it works very well with all sorts of music,and is even relatively easy on lesser recordings. When fed the digitalsignal from my Astin Trew AT3500+ CDplayer it sounds very much likethe analogue output of that player: switching from one to the other isalmost undetectable at first listen, except for a slightly morefriendly top end with the DAC, perhaps.

After a bit more listening it becomes clear that the Octave indeed hasa slightly less bright top end than the Astin Trew, but shows a vituallyidentical tonal balance over the rest of the spectrum. Perhaps this isalso the reason that the Astin Trew seems to reproduce slightly moredetail than the Octave, although I have to say that the difference issmall and only detectable with very good recordings and in directcomparisons. The Astin Trew also produces a little bit more air aroundinstruments.

Having said that, the Octave certainly doesn't seem to leave anythingout, even at the top end. If anything, this slight softness seems tohave more to do with the absence of distortion or digital 'edge' thanwith the absence of actual signal. Other players might show a bit moreextension at the top end, the Octave scores bonus points with itsextremely clean presentation and lack of smear.

Compared to the Astin Trew the sound is ever so slightly more detachedfrom the speakers, with a nice and relaxed character. The soundstageis a little bit more towards the front, but there's nothing 'forward'to it. The CD player simply projects a little bit further to the back.There's no difference in width, layering or focus, with both sourcesdoing a fine job.

It is certainly not the case that the warm overall character of theOctave is caused by an emphasis on the bass, but rather by this slightsoftness at the top end. The bass is actually well controlled and onlythe midrange shows a hint of added richness.

The Octave does hold the sound together exceptionally well when thegoing gets tough, even better than the Astin Trew, probably because ofthat friendly top end and the appealing richness to the sound.Whatever the reason, this DAC really sounds rock solid and totallycomposed without any edge, aggression or other nastiness. Pretty muchperfect, I'd say, but if your taste is more for ultimate detail andabsolute neutrality then the Tentlabs b-DAC I reviewed earlier would be the better choice,being a DAC that is pretty much perfect too, but in a different way.

I also took the Octave to a friend with a Naim CD5 CD player, withflatcap power supply upgrade. He uses a squeezebox with a BenchMarkDAC as well. I've used his setup to assess other DACs before and theOctave turned out to be one of the best ever. It basically matched theNaim player and the BenchMark DAC quite easily and did feel completelyat home in this company. The Naim is obviously strong with rhythm andpace, but the Octave had no problems keeping up and showed noweaknesses at all. In the end we couldn't really agree on which one ofthese three sources was the best, but I strongly suspect that, givenenough time, we could well have chosen the Octave. Given the naturaladvantage of the Naim player, working in an all Naim system throughthe preferred DIN connection, this is high praise indeed, certainly ifyou take into account that this player is over twice the price of theOctave.

I then took it to another friend to be compared to his new Rega DAC.The Rega is somewhat more affordable than the Octave, by a smallmargin, but a very impressive dac for the price. Definitely arecommendation, but I still thought the Octave sounded more naturaland coherent. The Rega had a bigger soundstage and deeper bass, butalso sounded more mechanical and artificial. It left a bit of a gap inthe middle of the stage and was less at ease with good liverecordings. The Octave was slightly dryer, but more refined andconvincing in its presentation. With more processed recordings theRega seems to do a bit better, but with more listening the innerqualities of the Octave will shine through, and the Rega can evenbecome a little bit tiring.

Both of these comparisons have been made on digital transports ofperhaps less than optimal quality: a Squeezebox and a PC. It was fairin the sense that the other DACs used the same source, but unfair inthe sense that the Octave definitely deserves a top quality transport.I couldn't do the direct comparison, but I'm absolutely convinced thatit sounded much better at the end of my Astin Trew than being fed byeither the Squeezebox or the PC. It was fine with the lesser sources,but only when it was being fed the digital signal by the Astin Trewdid it sound really exceptional. Make sure you audition it with a gooddigital source!

What is very clear is that this is a DAC that is more focussed onpreventing any nasty digital additions to the sound than to make sureevery last bit of information is reproduced. Not that it leaves outmuch, but its main mission is clearly not to irritate or distract andto communicate the music in the most natural way. It succeedsbrilliantly at this.

Conclusion

Physics Mini Projects

I suspect the Octave will appeal very much to people with preferencesthat go in the direction of vinyl rather than digital, as this is oneof the most 'analogue' sounding DACs I know. Not that it sounds likevinyl, of course, but it certainly lacks everything that vinyl loversdislike in digital, while still possessing virtually everything thatdigital has to offer.
Virtually? Does that suggest that it doesn't offer everything that digital is capable of? If that is supposed tomean that there's no better digital source available, then no, because I know there are CD players and DACs that are even better. But for the asking price, the Octave is quite amazing and if you like itspersonality then I don't think you will be able to better it at doubleor perhaps even triple the money. Very highly recommended.
