Audio Alchemy DTI Pro32 DSP Settings

Dave Hi.
Very nice ,detailed instructions on the use of the
AA DTI Pro-32.What do you think of the Digital lens?How does it compare to the Pro-32?
Thanks
George

Dave,
THANK YOU! You are a great help!

Roy...my pleasure, any other questions, drop me a line. You can also use (2) DTI PRO 32 strapped together for even more fun.

Yioryos...the Genesis Digital lens and the Meridian 518 are a level above the AA stuff. They have more robust power supplies and higher quailty internal parts (premium grade) than the AA equipment, which was built to a price point geared for high value.

With the Genesis and Meridian pieces retailing at nearly $2000 in their day, the $700 DTI PRO 32 filled a certain gap for those who believe that Dejittering had it's benefits.

The Genesis won't perform the dithering, I think the Meridian does, and calls it noise shaping. If you are using a older DAC which only operates at 16/44/48 there will be little or no value to dirthering. If you have a later model 24 bit capable DAC you could always use a outboard UPSAMPLER after your Lens.

I've never care for UPSAMPLING as to my ears it "Minuterizes" not "Shrinks" the sound stage, and seems to take something away from the leading edge of the "note". I also am not a fan of 1 bit Delta Sigma DAC's.

Give me a good old fashion 8 times oversampling, multi bit ladder DAC. They tend to have a slightly more forward balance (not bright), That seems to add speed and excitement to the presentation.

A 44.1 eight times oversampling DAC will operate at 352.8 (8x44.1) a 1 bit upsampling DAC operates at 192.

If you can find a Digital Lens or a Meridian 518 on A/gon for about $500 or less buy it. Make sure you get the remote with the Genesis piece.

Two other interesting pieces in the Jitterbug arena are the Monarchy 24/96 ($150 used) and the Camelot Dragon Pro MKII.($800 used with AC3/DTS chip) Both these pieces will handle 24/96 data streams and pass a AC3/DTS signal. Nice if your HT is intergrated with your 2 channel.

Both these pieces have transformer coupled output stages which tend to be quieter, than the typical (price point) capacitor coupled output stages of the AA equipment.

The Camelot piece will also do Resolution Enhancement (dirthing), the Monarchy will not.

I use 2 (double jitter) Camelot Dragons Pro MKII in my HT set up.

Dave,

There are some errors in the information above that need to be corrected. I suspect your comments concern the original Dti Pro, and not the Dti Pro 32, which is the subject of the thread.

The Dti Pro 32 retailed for $1595.00 not $700, and it is a much more sophisticated beast than the original Pro. It is also capable of 16,18, 20,22 and 24 bit resolution, not just up to 20 bit, as you mentioned.

Also, the resolution settings that you list are incorrect. The correct settings are as follows:

HDCD off off off
16 bit off off on
18 bit off on off
20 bit off on on
22 bit on off off
24 bit on off on
none on on off

The method of toggling the LED's is as you described.

This unit competes favorably with the Genesis Digital Lens, but works best in an all AA system using the proprietary I2s bus between DDS Pro Transport, Dti Pro32 and DDE V3.0 Dac. The V3.0 is HDCD capable and the Pro32 can pass HDCD.

Gentlemen,
Your input is greatly appreciated! Thank you to all of you.
