Hi. I have two Parasound DAC 2000 Ultras for sale. It's a balanced dac made during the period of 1998-1999 by Parasound. It is based on the Ultra Analog discrete ladder dac chip the legendary UltraAnalog D20400A. Ultra Analogue has since been acquired by Wadia. It was originally priced at I believe 2000 US dollars.
It also uses the Pacific Microsonics digital filter the PMD100 which is considered one of the greatest digital filters ever created. This allows it to decode HDCD.
It also has a custom input receiver created by Ultra Analog.
It accepts tos link/coax/st optical/aes ebu as inputs (4x digital inputs) and has balanced xlr output as well as single ended rca output.
I am liquidating these two dacs as I now have a much better balanced dac based on the same two aforementioned parts (UltraAnalog Chips and PMD100) aka my Spectral SDR-2000 Pro which was originaly 9k and now can be found used for ~3k.
So I have two of these. One is 9/10 audiogon condition as you can see from the pictures posted below. The other is 10/10 as it is essentially new in box. I only opened it briefly to test it upon receiving it and then repacked it.
I am looking for SOLD shipped in the US (Fees/Shipping covered by me) for the 9/10 one. It does not come with original packaging or a manual. I will include a computer power cord
The manual is located here online:

I am looking for SOLD shipped for the 10/10 one. This of course comes in all original packaging with manual and everything else.
Specs copied and pasted from the website:
The D/AC-2000 features a state-of-the-art 20 bit D20400A dual digital to analog converter and custom AES 21 digital interface receiver designed and manufactured by UltraAnalog, Inc. The D/AC-2000 also incorporates the High Definition Compatible Digital®PMD-100 HDCD®process decoder developed by Pacific Microsonics. This decoder performs precise decoding of HDCD encoded recordings and also functions as a superb digital filter that will enhance the sonic quality of non-HDCD encoded recordings

Here are pictures of the 9/10 unit. As you can see it is in flawless condition, but due to age/use by audiogon standards it must be considered a 9:

Feel free to PM me if you have any questions or interest. I believe one of these was listed on audiogon a couple weeks back for $725. I didn't check to see if it sold or not, but the listing is gone.
NOTE: It does not do USB input. I used a hagusb usb -> coax converter and I would offer to sell that too, but I'm using it in my office rig now.
