Up for sale is a used and slightly modded Entech "Number Cruncher 203.2" 20-Bit Stereo DAC w/ original power supply.
I made a few changes to the DAC.....
OPA2134PA swapped out for LME49860.
Panasonic FC in place of the old Nichicon VX main supply caps.
600R output resistors changed to 100R Dale.
CS8412 filter mod.
I also installed a relay that disconnects and shorts the output when there is no signal locked. I did this because the DAC produces a "hisssssss" sound when it is not locked on a signal which can be very annoying if the amp stays on but the source is turned off.
Also included is a Tripath TA2021B based amplifier housed in an old 203.2 case. There is an ALPS 10K log pot installed as a volume control that also has a switch that controls a power relay for the amp board. I will also include a 14V 3.21A "line lump" power supply.
The price for the pair is $120 shipped (US only).

Two of these DACs sold on eb*y recently, one for $76 + shipping and the other for $89 + shipping. A T-Amp in a case will run you around ~$40, and this one even matches the DAC.
