Customer Reviews

This is a great product. No hum Finally brought back life to my old Turntable that has not been used in 10 years. This is a great product. No hum, No noise, Ground works great, Gain control is fantastic. Volume out of this unit matches my other equipment that is also plugged into the same receiver/powered speakers. Extremely happy with this purchase. I m using a powerstrip to act as the ON/OFF button so that does not bother me. The audio quality out of the unit made my previous setup sound like complete garbage previously using a mixer with built in preamp . One of the first tracks I played was Radiohead Sit down, Stand up and the vocals instantly gave me chills. Sounded rich and alive. Side effect of this sounding so good is that I bought $200 in vinyl the next day so yea. :-/ 5Deal of the century...before you go plunk down $300-600 for a high-falutin' "audiophile" phono preamp...consider this: Remarkably clean sounding for the money--rivaling phono preamps I have heard in the $400-700 range. This has to be the phone preamp deal of the century. Runs quiet with tons of musical definition, detail, and soundstage. I do not have any problems with hum as mentioned by another reviewer. Things improved further in terms of transparency and sound stage when I switched to 12v DC battery power using a small rechargeable lead acid battery, splicing in the provided plug to battery lugs. The 5AH battery lasts around 40 hours of listening between re charges but makes a nice difference--worth the extra $12 for improving this little preamp. The sound became more detailed and warm when I then added an inexpensive Little Bear tube preamp inserted after the aforementioned Pro Audio preamp. This rig now plays vinyl like gangbusters with my Pioneer P-L7 turntable, Nagaoka cartridge, and 1958 Eico 6L6 monoblock amps. You can add the 12V battery and Little Bear tube preamp for around $65 extra--then you really have a super smooth system. Total analogue fun! 5Million $$$ Sound if you... I've been using the ART DJPRE II for about four months. Now that I have everything configured, the sound is breathtaking. It rivals other phono preamps costing thousands of dollars. NOTE: Be sure to connect the DJPRE GROUND terminal to your phonograph GROUND terminal via a separate grounding wire (spade lug terminals recommended). Also, be certain your phono is connected to a good earth GROUND. It DOES matter!The real trick to get exceptional sound out of this little gem is to feed it what it likes best... that is a diet of PURE 12 volt DC. For a cost of about $30 you can build your own 12 volt PURE DC power supply. I've posted a picture that shows the details about how to do this. This little simple DIY project also gives you the ability to conveniently turn the unit on/off from the front. This is a feature other reviewers have noticed the DJPRE II is missing and would sure be nice to have.UPDATE Nov 2, 2013: Amazon moved the picture(s) I posted. To see picture(s) click on hyperlink of my reviewer name, then select the tab for "Images," and on that page scroll down and select hyperlink for "Image Gallery." You will find picture(s) and DIY instructions there.Initially, I'll admit I was a little disappointed. While the sound was very good, there was a subtle but yet unmistakable 60 Hz hum that I just couldn't get rid of. All the grounding tricks in the world, and believe me, as a retired military electronics engineer, I know MANY grounding and RF/EMI shielding techniques, I could not eliminate the hum. I just couldn't live with the unwanted noise. The unit's only drawback turns out to be its own supplied power adapter/converter. The unit's operating voltage is spec'd at 9 to 12 volts (AC or DC). The DJPRE II that I received from Amazon was supplied with a 120V AC to 9V AC adapter. NOTE: As of the writing of this review Amazon Product Features says "12V DC (Adapter included)" - a little discrepancy, but no big deal.I tried using other power adapters (I have many). I tried 12V DC, 9V AC (supplied with unit), and just to see how rugged this little dude is, I even tried a 15V DC adapter. The DJPRE II performed about the same, regardless of the power adapter used. That low level but annoying 60Hz hum was there in every instance.I began researching the high end audiophile grade phono preamps costing between $2000 to $7000. Being a technical engineer, I check out the spec's very diligently. I noticed that some of the high-end preamps, although connected to a regular 120V AC wall outlet, actually use an internal relay switch that switches to internal "battery power when operating" and then when not in use, the internal battery is charged by the standard line voltage (converted and rectified to DC of course).After a trip to my local electronics retailer, about $30 in miscellaneous parts, and a little creative ingenuity along with a can of spray paint and my prototype build time, I was ready to try out my theory. I plugged my custom built PURE 12V DC power supply into the DJPRE II and I was instantly transported to musical nirvana (and NO 60 Hz hum)!FURTHER INSIGHT: If you check out the photos I posted, you will see that my system uses a non-resonant Sumiko HS12 headshell mounted with a Lyra Delos MC (moving coil) cartridge, that is fed to an Ortofon Verto step-up transformer where it is converted to the MM (moving magnet) output level required as input for the ART DJPRE II. The ART DJPRE II is NOT able to use a high-end, low voltage (typically .5 mV or less) MC cartridge output directly. The ART DJPRE II is designed for use with MM cartridges, output loading: 47 kOhm / 100 to 200 pF. The output range for MM cartridges is usually somewhere between 4 to 9 mV.I highly recommend this product if you are willing to build a very simple 12V DC power supply. I guarantee you will be amazed at the sound quality that fully complies with RIAA standards. Happy listening to all. 5The Wicked Witch is dead! All I can say is wow! I have A LOT of money (5-10 grand) tied up in my audio system including a sweet Denon S930 HEOS receiver. The weak link has always been that turntable. Although my really nice Ortofon cartridge cost almost as the turntable, I could only turn it up to maybe 40% before the hum/buzzing in the speaker's drivers caused me extreme pain.... This little wonder has completely eliminated all of that. I can still hear every high and low, pop and crackle but none of the annoying background noise. The capacitance switch doesn't make much of a difference in my system, the adjustable pre-amp gain control works best at -1 (my normal listening level) but is easily adjusted so as not clip at higher power levels, and has a helpful green to red LED indicating clipping (if you can't hear it). I use the low-pass filter turned on. As others have said, the blue LED is too bright but i can live with it. For the price and what it accomplishes, I'd buy it again without any hesitation. My vinyl finally sounds like it should at the appropriate power level it deserves! If you are experiencing the same issues, buy it..I'm guessing you won't find a better product for a better price. 5Sounds great but needs a power switch! I have it set up between an old Harmon-Kardon turntable and a new Yamaha receiver. This sounds so much better than any receiver with a built-in preamp in the sub-$1000s range. Those preamps are put in as afterthoughts or gimmicks. It's much wiser to spend your money on a separate, solid preamp like this. It would be hard to do better than without spending several hundred. Make sure you connect it to your turntable with a fairly short cable (mine is about 3 feet). Cable length to the receiver doesn't matter as much.My only complaints with it were that it has no on-off switch and that the power indicator is incredibly bright. Not wanting to stare at this glaring miniature sun at all hours and finding plugging/unplugging the unit more than a little inconvenient, I went and bought a $3 in-line switch from a hardware store and wired it into the power cord. Both problems solved! 4Easy Bridge Between Analog and Digital Looking for a pre-amp to connect your 20th century turntable to your 21st century amp/receiver? This one does the job with a minimum of fuss.The DJPRE offers a quality, unfussy build that's a plug-and-play (with a little adjustment) proposition. It's a small footprint, employs one level setting knob, and doesn't require any further skill save for plugging it in.The only annoying thing is that once plugged in, this is an "always on" proposition. There's no on/off switch, and I'm not a fan of powering components I'm not using at the time. So just unplug the power connection to the back and plug it in when using the turntable. Just position it where you can do so easily! Don't like yet another power light shining on the rack? A small square of electrical tape will fix that. At the very least, the blue light on this will remind you it's powered on.There are so many choices out there. This does exactly what you want it to do. 4Clean sound This thing fantastic. Added a good bit of clarity and stereo separation.The gain control with clipping indication is pretty neat,green LED blinks red if signal clips.The wallwart that came with the preamp has some heft to it (unlike the switching phone chargers). So I assume there is a transformer in there which is always a good thing. I don't hear any power supply noise coming through. Clean sound.As others have said, the power on LED (blue) is way too bright. I had to cover it with electrical tape.The capacitive coupling (100pF, 200pF) adjustment and low-cut filter are transparent buttons with an amber glow when depressed.In the attached video, the line out of the DJPRE II is connected directly to the camera mic input.I definitely recommend getting this. 5Works great After my trusty (40 year-old) Denon receiver coughed up a hairball, I found myself in the market for a phono preamp for the first time. I figured a phono preamp is a simple device -- how can anyone screw this up? Well, some did, big time. Before I purchased the ART DJ PREEII, I tried one that cost about half as much. I would be kind if I said the cheap one made my records sound like crap -- it was truly awful. By contrast, this unit works just fine. I know there are cork-sniffing hi-fi enthusiasts who believe you need to spend major $$$ on every component in order to squeeze out every last drop of fidelity.This is not true. As a guy who spent a lot of time in studios and mastering labs doing critical listening to master tapes and test pressings, I can assure you this little guy gets the job done.The gain control is particularly handy, as you will soon discover the wide range of signal presented by different recordings. Don't be afraid to let the gain run into red-light flicker territory, as long as it is just happening on the loudest transients...it won't affect fidelity. 5Awesome little gadget! This was my first preamp phono amp. It works great as far as I can tell, my 40 yr old TT was punched up, it didn't have a preamp. So I went one step further and purchased a new TT that had a preamp. Audiophiles will tell you to rip out the old preamp for this particular TT and use a separate preamp. Not wanting to void the waranty, I left the preamp in. The ART pre STILL works terrific! Sound stage opened up, clarity improved using the same Ortofon cartridge. And I could not believe the price on this full range product! When most good preamps cost hundreds up to one thousand, I really don't know what they could possibly do that this one does not. Pay close attention to the instructions on WHERE to plug in the preamp to the receiver/integrated amp inputs, DO NOT PLUG INTO THE PHONO JACKS. Find an open Aux or Tape jack to plug into. Happy listening! 5Doubles as a nightlight The sound quality is good on my setup without the use of either the low cut rumble filter or the selectable cartridge loading. The gain switch isn't in a constant/fixed position because, ideally, it has to be adjusted for optimum results with each record.I think that it's a very good value for the money but there are two issues with it that bother me. 1) the blue LED light on the front is ridiculously bright and obnoxious. They need to tone that way down or switch to a dimmer color altogether. 2) there is no power switch on the device so it is on all the time.It definitely sounds better than the built-in preamps on turntables so equipped.I would recommend it for the modest investment but I'd also suggest that you look into the rolls VP29 Phono Preamp or the TCC TC-750LC BLACK Professional Moving Magnet Preamp as these are all in the same price range. 3
