Dear friend from Australia

I am having the Audio Alchemy DDS PRO DTI PRO 32 AND V. 3. Every time I turn on the dti it does not recognize the dds pro. So I must turn down the dti disconnect the dds pro and turn ii on alone.
have you any idea of how to solve this problem. My email is crisage@msn.com

DDS Pro, DTI PRO 32 with AD chip upgrade and PS2, DDE 3.0 with 89C51 microprocessor and RW1 (recently replaced with Camelot Uther 2.0), all connected with Camelot Excalibur III I2S buses, DLC & RW1 have been replaced with the Legacy High Current Pre-amp (which can be completely bypassed for less sound degradation owing to Uther's analog domain volume control), AA OM90.1 pure class A balanced monoblocs, Legacy Whisper speakers with Steradian, Nordost SPM and Red Dawn interconnects, and Nordost SPM biwire speaker cables. The PRO 32 is an excellent sounding unit capable of providing outstanding resolution enhancement. Bass became tighter and had more snap. Highs were cleaner and much more accurate; cymbals had more shimmer and better decay characteristics, without any of that sizzling bacon effect. Imaging was greatly improved, with a deeper and wider soundstage, and more air between individual instruments and voices. Vocals became more fluid and lifelike. Interestingly, direct AB comparisons of the PRO 32 with the Genesis Digital Lens while the DDE 3.0 was still in my system, revealed a marked superiority of the Lens over the PRO 32, primarily in improved bass control, which was faster and more detailed, and in improved imaging. The PRO 32 was flatter in comparison. However, with the Uther 2.0 in place of the DDE 3.0, the PRO 32 faired much better in otherwise indentical AB testing, becoming almost the sonic equal to the Genesis, with only slightly less refined bass control, and a barely less layered soundstage, and at a lower price. I highly recomend the use of I2S buses where possible. Additionally, there appears to be no loss of component "synergy" when substituting the non-AA equipment I've listed, including the Legacy pre-amp, and especially and for obvious reasons, the Camelot Uther 2.0. My DDE 3.0 and DLC & RW1, as well as my previous transport/player and power amp (DDS III and AA OM150) have found their way into a very nice sounding, smaller, second stereo system, along with a pair of System Audio 950 speakers, and Legacy and Nordost Blue Heaven interconnects.

5 stars if it wasn't for the price. This device works quite well with Camelot DACs. Better soundstage, detail, and overall transparency without the dryness. It's simply an irreplaceable component in my system.

I have listened to many so called high end systems (I work in Hi-Fi industry),I think with many brands you are just paying for the name.Anyway I digress, the DTI Pro 32 makes a great improvement to just about any CD system,especially if you can use the I2s inputs/outputs.
It seems to bring out every little detail.Super dynamics,the best sounstaging I've heard (check out Patricia Barber's album Modern Cool).If you can find one now (used)get it,I don't think you will regret it.

The DTI Pro 32 is an already excellent product, as anyone who has integrated it into their system will tell you. More good news is that you can take your system's digital to analog conversion performance up to a completely new level by daisy-chaining a second DTI Pro 32 between your current DTI Pro 32 and your converter (preferably the DDE 3.0 with it's I2S input). With both DTIs set to the appropriate dither settings and connected via their I2S inputs/outputs you will find that the real limitation to your system's resolution will be the quality of the CD's master and/or it's transfer to CD (very real concerns). I run the (variable) output of my DDE 3.0 directly to my amp. The transparency of this setup is unrivalled for the package price.Tweaks- the DTI Pro 32's resolution enhancement "engine" can be upgraded with their adaptive dither chip upgrade. Another enhancement is to toss the stock I2S cables and use a higher quality shielded I2S cable (another benefit here is less interference with your TV signal). And yet another enhancement that becomes even more important when you daisy-chain the Pro 32s is to use the upgraded/regulated power supplies (e.g., Power Station 2). These regulated supplies allow the Pro 32's voltage regulation dept. to loaf, providing better sound and a cooler unit. The result of all these upgrades is a verrrrrry relaxed yet highly propulsive holographic soundstage. Image placement is very 3-D (3.5-D?).

Tried several times to submit this review under the exisitng category and post but no luck. So here goes anyway. These little black boxes are available on the used market for $500-600. Try to verify B4 you buy which chip is resident. You need version 3 or 4 to work properly and I would not recommend buying one of these without first making sure of the availability of a replacement chip (HCM, Music Direct or Channel Island Audio). As a jitter reduction box, it has no peer except for maybe the Genesis Lens. As an adjustable word length, Digital signal processor and HDCD decoder, it can't be beat at the current price point. Where this little box shines is extrapolating 24 bit word length from 16 bit cd's and sending it virtually jitter free to the dac of your choice via Aes/ebu, I2S or coax. 20bit dacs work great with this unit, 24 will work better. Set at the 24 bit word length, going thru a high quality 20 bit dac, you can hear more detail, air and extended highs and lows. Cymbals on some recording seem to shimmer thru the Pro32 where without they are meerly there. The 32 does not alway s work magic on recordings. Higher bit mastering seems to work especially well; Mofi, the New Blue Note RVG 24bit masters and other premium discs. It only makes since that if 20 or 24 bit mastering is used and then down sampled that the DSP extrapolation software in the pro 32 "could" reproduce those same bits. It may not do it bit for bit but it does do something that sounds incredibly right. The 32 also does HDCD, that is it passes the HDCD code intact to an HDCD capable outboard dac if you set the mode buttons to HDCD. Maybe soemday there will be a box that you can select GAIN, GAINII, Superbit Mapping, etc. to decode the way HDCD works now. Until then there is the 32 or the $5000 dCS Purcel or $7500dCS 972 which upsamples with a more extravagant algorithem than possible for $500.

Transparency, tightness of bass, airyness of highs, overall incredibly smooth sound.

None.

This machine is magnificent. Since it is available so cheap you can pair it with a relatively inexpensive cd-player with HDCD capability and then you will be getting sound that in my opinion approaches the sound of systems costing thousands more...

I use high end dynamic headphones (HD600's) for my listening. Using headphones gives me an advantage in perception of details and extreme subtlety of the music. The effect of the Dti Pro 32 in my experience was simply all around improvement. The first thing you may notice is an increase in the overall smoothness of the music. Just behind that I noticed the control it exerted on the bass. Bass that might have previously bleed into other frequencies is brought back under control yet still has a sense of being powerfull. The treble is the most subtle and in the long term pleasing refinement. The treble is put into greater focus yet remains calm and un-fatiguing. The effect is perfection of treble, detailed yet unfatiguing it is perfect, perfect, perfect....

I use the Dti with the MSB Link Dac 3 and find the combo to be good together, but the Dti pro 32 easily out performs this Dac so if you can afford it go for something a little closer to top of the line. Or you can try upgrading the Link Dac to HDCD compatibility. Something I haven't done yet but plan to very soon.

things to look out for:
Be aware that performance is dependent on the chip installed in the unit. you should get the very latest upgrade chip which adds HDCD functionality and improves the overall sound. I got mine from channel Island Audio. if you need the number to order one email me...

In the end I must say I expected alot from this unit and got more than I could have hoped... It does those things that are barely measurable exactly right.

My dig front end: Theta Pro Basic II and an EAD T-7000 transport.I just wanted to concur with above reviews in my enthusiasm (of course who takes the time to submit bad reviews??). I picked up a DTI Pro (not 32) for $399, although it is essentially identical to a 32 per Rob Harley, which is a steal considering the great benefit it has on digital separates. My only twist to add to the techy talk above is, you an try to save money also by connecting your drive to processor with Rad. Shack rca connectors. I had great results with this after trying some expensivo cables -- unless you like to spend bucks for ultra audiophile cables. This jitter redux device really does work. It improves virtually EVERY aspect of the music, and you don't have to sacrifice a bit of dynamics, aliveness, etc. -- it improves those too. So if you've already spent far too much on a digital front end but hear harshness, look for one of these in the used classifieds. They ARE going for great bargain prices and are worth the investment.

Teac T1 transport trichord clock 2 modified, seperate PSU,silver AC chord connected to Audio Alchemy DTI PRO 32PS2 via I2S bus cable made possible by the
Audio Alchemy EDI v1.0 . The DTI PRO 32 is connected to Audio Alchemy DDE V3
DACPS3 via I2s bus Cable.
This has to be a match made in heaven. The 3 components work extremely well togeter, very neutral and without the digital nasties that so often plague the medium. Compared to vinal it still has something to aspire to ,but this is compared to turntables costing twice the price. I have herd only one better digital front end. That being the Mighty Levinson transport-Genisis Digital Lens-Timbre T1 DAC, weighing in at the price of a small house!. I2s cables are
Audio Magic 'Mystic Reference'. dont tale my word for it, check it out for yourself!.

System:DTI pro32, DDS Pro, DDEV3.0, all by Audio Alchemy, all connected by Camelot Audio Excalibur III I2S bus cables; YBA Integre integrated amplifier;
Merlin Music Systems TSM RC speakers; JPS Superconductor interconnects and
biwire speaker cables.

Comments: Both the DTI Pro32 and DDS Pro are worthy of accolades (as are JPS and Merlin products, even more so!). The effects a DTI Pro32 will have will differ
from system to system, but when a good match is found, the effects are staggering -- better pace and rythym, better definition, a more visceral conection to the music. With the demise (or at best long hiatus) of Audio Alchemy, some of these units are available at tremendous bargain prices. Repair
work can be done at Channel Islands Audio (I do not have the tel.# currently, but received it via Music Direct at 1-800-449-8333 when I purchased my unit).

Note: For those not yet aware, the I2S hookup has tremendous benefits--
fortunately, Audio Alchemy was not the only cost-conscious cutting-edge
manufacturer to employ that technology: Camelot Audio products use two different
types of I2S cables (including a proprietary 6-pinform). They offer similar
products, in a similar price range, but of different design (and in many cases newer generation technology). In the not too distant future I will be replacing the DDEv3.0 with a Camelot Audio Arthur 3.0--similar list price, amazing sonic improvement.

Rating for DTI PRO32: 5 OUT OF 5.
