Have you heard of Direct Digital Amplifiers? Yes? No? What about Power DACs? They're pretty much the same animal so if you've heard of one then you've heard of the other too. In a nutshell, a DDA or PWR DAC is a small, integrated style, unit that does away with an actual DAC chip and uses the digital stream (via a pure digital DSP chip) to directly drive a switching (or class D) amp. It is an interesting idea that was fairly low key until NAD brought out its C390DD. Now the NAD C390DD is circa $3K aussie and making some serious waves in audio circles, but what DDA or PWR DAC offerings do we have from other manufacturers? Well, nothing from most of them (the tech has yet to catch on in a big way.), but there are a few budget offerings available. Wadia have an offering in the 151 PowerDAC mini which until recently retailed at $1200 but can now be had for under $800. http://www.wadia.com/products/amplifiers/151/ NuForce have two budget offerings in their “Digital Input Ampsâ€, the DDA-100 ($650) and the Dia ($250 to $300). http://www.nuforce.com/index.php?option=com_k2&view=itemlist&layout=category&task=category&id=48&Itemid=339 Chinese company QLS have their QA100 “Full Digital Stereo Amplifierâ€. RRP $380 purchased direct from QLS and delivered to your door in Oz. http://www.qlshifi.com/en/wzcapi/qa100.htm And Hlly, another Chinese company, have their D3 and D5 amps which they (for whatever reason) choose to list with their gainclone amplifiers. A D5 will cost $380 delivered to your door from China. http://www.hllyhifi.com/index.php?main_page=product_info&cPath=66&products_id=281 And the big question on everyone’s lips is: “Do they sound good?†Well, as I have discovered, the answer is “Yes.†This all started when I read a snippet of news on John Darkos DAR website announcing the release of the QLS QA100. How dare he announce news that is this addictive! Anyway, wether it’s JDs fault or not, over the last 12 months I have managed to collect one example from each manufacturer, a Wadia 151, NuForce DDA-100, QLS QA100 and Hlly D5 so, let’s see how they compare shall we? I'll start with a pic or three. From top to bottom, Wadia, NuForce, Hlly and QLS. In the past I have had a few issues with these DDA units dropping channels and cutting out so I thought I would give them a bit more of a workout than usual so I came up with a test just for them, I called it a Power Delivery test. I stuck Dire Straits Heavy Fuel on the player and jacked up the volume until something gave in, the results are rather interesting. The rest of the test system details are as follows. Source is a Consonance cd120 via digital out through a $20 Crest cable into the amp and then via Lenehan speaker cables to my Lenehan S2s. The S2s, while easy to drive are not very efficient, 86db*, so they take a bit of grunt to get them to puch the volume up. Wadia 151. 25W into 8Ohms. $750-ish. John Darko has beat me to this one, he has an excellent review of the amp here: http://www.digitalaudioreview.net/2013/03/wadia-151powerdac-mini-amplifier-review/ So I won't go into too much detail except to say that this little thing sounds superb, its strengths are clarity and detail but it does an excellent job on everything really. The only criticism I have is that the bass could be a little deeper but that's being extremely picky. When it comes to micro detail and sweetness to the ear the Wadia is hands down the winner of the pack, it does seem to be a little low in the power department but as long as you are not into heavy rock or metal that is really not an issue. On the Heavy Fuel test I maxed out the volume (80 on the screen) and that translated into 97.2db on my SPL meter. Not bad at all! NuForce DDA-100. 50W into 8Ohms. $650-ish I was expecting good things from NuForce as they have a reputation similar to Wadia and class D amps are their speciality but I'm afraid this amp was a bit of a let down. Yes it has a good amount of power and it certainly shows no breakup on the highs but it is just a bit too neutral for my taste. I would call it accurately neutral but bland, it needs a little more zing and a fair bit more soul. Certainly not a bad piece of kit but just not emotional. I have had a channel drop out on this amp in the past but in this test, no matter what I did I could not get it to misbehave. On the Heavy Fuel test I pushed it up to 98db and held it there until my ears gave out, that 98db was reached with a few more numbers left to go, 4 from memory, on the screen. At this volume level it was pretty hard to handle the NuForce, but the Wadia maxed out was actually OK to listen to. Hlly D-5 110W into 8Ohms. $380. This puppy has an attitude, it sounds good, nice and strong and clear (not in the Wadias league but more enticing than the NuForce) but a bit agro. Almost like it was born wanting to sing for Def Leppard. I have to say I liked the sound of this amp, it wasn't going to be everybodies cup of tea because it was obviously intended for rock and metal music but I have to say it did better than I thought it would on lighter vocals and metallic highs and it kept the edgy sound throughout. It delivers nice deep and strong bass and has a more focussed attack than any of the other 4. But there is a background story to this one, the amp on Hlly's website is listed as 80W per channel so this one is either the updated version or an experimental one. When it arrived and I went over the invoice it stated the value as $30 and that it was a pre-production model for demonstration use only. I decided to fire off an email and ask what the go was but the website I bought it from has ceased to be (bye, bye HiEndKing), it has a completely different power supply to the 80W unit shown on the website, that unit has a torroidal transformer and this one has what I am guessing is a switching power supply with a similar design to the other units. I am hoping that this unit is a prototype because on the Heavy Fuel test it started to cut out and cut back in at a mere 86.4db, there is no volume display so I don't know how far along the "dial" this was but it was reached very quickly. A very disappointing result! There is no way I could possibly recommend this amp if there is something obviously wrong with it. QLS QA100 60W into 8Ohms. $380. I've had this one the longest, long enough that I covered it in my "Addicts Guide" thread back when I was using my Osborn Eclipse speakers. I liked it then and I have to say it sounds a bit more capable through the S2s, the Eclipse were a fussy speaker in the highs where the QA100 showed a little bit of standard class D behaviour but the S2s are not so fussy and that class D behaviour is completely absent from the QA100 I am listening to now. It doesn't have the clarity of the Wadia but it does have far more soul and body than the NuForce and it has a nice deep but smooth bass that beats out both of them. There is also one little handy function it has which is that it remembers the volume settings of each of the imputs, I found that very useful when moving from music to TV. The Heavy Fuel test produced a 98db result very quickly with more room on the dial to go, it did get a little tinny above about 92db but that's fairly normal. So from loser to winner we have: 4. Hlly D5 Can't get to 87db! And you call yourself a rock amplifier! Hang your head in shame! 3. NuForce DDA-100 Not a bad amp, but just not anything special. The base model Camry of the PWR DAC world. 2. Wadia 151 (For those of us that like rock.) or QLS QA100 (For those of us that like vocals, Norah, Dianna, Peggy, etc.) 1. Wadia 151 (For those of us that like vocals, Norah, Dianna, Peggy, etc.) or QLS QA100 (For those of us that like rock.) If I was rating things purely on a value scale I would have the Wadia 2nd and the QLS 1st but really, it depends almost completely on your intended musical target range. If you are after a small form factor and good quality sound the Wadia and QLS units will not disappoint, the NuForce amp may be what you are after if neutral is your thing but on the subject of the Hlly, I would wait for the next model before I tried again. Remember the * next to the 86db way back above the Wadia section? Well it was there to remind me of the reason I started this whole thing. Everyone is talking about the Usher S520 as being a kick arse bookshelf speaker at a rock bottom price but it (like the S2s) has a low efficiency and so needs an amp that can deliver some grunt to make it get up and really sing at volume. The Redgum SG5500 is a popular choice but is now only available second hand and if you want a cheap amp with grunt then your choices are pretty limited, hence my investigation of the Hlly, NuForce and QLS amps above. At $380 bucks the QA100 still breaks the '50% budget on speakers and 30% budget on amp' rule but it is the cheapest candidate I can find that I think will really work. I'll have to investigate the matter further when my S520s arrive. Cheers folks!

Location: Mosman 2088 Price:$350 Payment: PayPal+3%, Paypal as friend, COD RFS: Surplus, not being used. Description: The DDA-100 represents one of the best and most uncluttered audiophile stereo set up in today's digital world. It will accept sources from 3 digital input sources and can act as a USB-SPDIF converter to another system. If your main music source is from a streamer like Apple Air Express, or even Sonos Connect, then this amp will deliver non fatigue sound with aplomb The most surprising part of this amp was how effortlessly it was able to drive my Vienna Acoustics Hayden's, which at 4ohm impedance, is no small feat.
