Accuphase DC-1000 Processor/DAC


After a recent thread on streamers I decided to look into DACs, particularly the Accuphase DC-1000.  Currently own an Accuphase DC-37 Processor/DAC . My Innuos Pulsar feeds the DC-37  via Innuos Phoenix USB out. The DC-37 feeds my Accuphase C2300 preamplifier via XLR.  Seeing that streaming is my only source for music,  I'm considering upgrading my DAC to the Accuphase DC-1000 and I'm wondering if this is an actual and noteworthy upgrade.

@audiopacer well I did it! I bought an Accuphase DC-1000. As soon as I have it plugged in and running I'll report back.  I can't tell you how excited I am.  

Congratulations!

Just a warning to all Accuphase dac users (applies to CD/SACD players as well):

avoid hot swapping the USB cable, there's a risk it could damage the USB receiver.. Just turn off the dac first. 

Thx @donquichotte ! I’ll keep that in mind. That is an unexpected failure mechanism- usb interfaces are usually highly resilient to ESD and live insertion by design. Accuphase is also super conservative with their design execution. If you don’t mind my asking, what did you experience that led to this warning?

Thank you

@audiopacer : I asked an allegedly knowledgeable Accuphase service man in Poland about a USB input glitch in an Accuphase SACD player and he said it's the USB receiver that has been (slightly) damaged most likely due to hot insertion.

Also, I have read that at least the Accuphase DC37's USB input is prone to being damaged by quick power on/off cycling and such. Maybe other Accuphase machines are just as sensitive. Better safe than sorry. More details at the links below:
