My PerfectWave dac is working!

have you tried another digital source into the dac besides the CA Transport? A streamer, or a CD Player, or even a television?

The first step would be to see if the DAC works with other digital sources. If it does then the issue must be the CA transport, or the handshake between the transport and the DAC.

If other digital sources fail to produce sound via the DAC then the problem is potentially the DAC or the Preamp. Does your preamp have an included DAC?

From what I can tell it doesnt, but if so, then...

You could be connecting one DAC to another, and then you wont get sound

Have you actualy produced sound before from the seperate pre and power amp with any other component?  If you haven't then look there first

I think that you are wasting time and money by trying different tubes

No, I recently purchased the pre and the monoblocks. Right now I’ve no sound with them with either the dac or the phono pre. So I’m wondering if the problem is with the pre or the monoblocks. 
 

Initially I thought the issue was with the dac. I had no idea I had no sound between the pre and monoblocks. I’m going to see if I can connect the pre to an integrated later today to see if it works. I’ve no other digital source. 

No, I’m not saying the amps and pre aren’t working. But currently I’ve no sound with either the dac directly connected to the amps, or the dac connected to the preamp, or the phono preamp connected to the preamp and monoblocks. It’s a dilemma I know. Thanks anyway.
