selling my GW Labs DSP.
price new was 400$ asking 275$ obo. now 250 $ !!!!!!
OR trade for a Tact Dac card for 2.2x .
you could use this unit as anti jitter / to upsample / to convert from different digital formats / to add more digital inputs / etc.
lots of options . i remember reading some reviews a while ago that were very favourable.
buy with confidence , check my audiogon feedback under the same name .
here is some information from the centasound web page:
The DSP is a digital-to-digital upsample processor that converses the PCM (Pulse Code Modulation) digital signal with sampling frequencies ranging from 32-96kHz to 44.1 or 96kHz. It is used between a CD/DVD transport and a DAC (digital to analog converter). It enhances digital signal from a CD/DVD transport and output cleaner digital signal to a DAC. The enhancing process will result in better sound.
Marked sonic improvement is attainable with ANY DAC. Although not all DACs have the capability to accept an upsampled 96kHz frequency, a DAC operates at the standard S/PDIF (Sony/Philips Digital Interface) 44.1kHz sampling frequency will sound better when partnered with the DSP. Of course, greater improvement is possible with 96kHz capable DACs.
The DSP has the following features :
Signal Conditioning (jitter reduction)
Signal Boosting (10 times higher)
Signal Isolation (cleaner signal transfer)
Sampling Frequency Conversion (from 32 to 96 KHz) to 44.1kHz or 96 kHz (user selectable)
Precise Clock Generation. It does NOT use the recovered clock from your transport.
Bit Extension (from 16 to 24 Bits)
Dual Choked-filtered Power Supplies
It has 3 input and 2 output modes :
