Any comments about my earlier suggestion:

Speaking about that: the USB board also has a SPDIF output. Would it be smart to link that to the new Wolfson SPDIF receiver, let it decently reclock there, and then let the data go to the DAC from there, in stead of directly linking the USB receiver to the DAC? My guess is that jitter might be reduced even further (the PCM2707 doesn't really say a lot about that though).

An added bonus might be that switching the SPDIF signal might be a lot easier that switching I2S.

What would you recc. for high quality (type of wire and gauge) to use as wiring between the:

cd-player and receiver
receiver and DAC
DAC and Balanced Output Sockets
power supply (yours) and components

Thank you
Darren

Here's what I use...

cd-player and receiver
Generic RCA cable that came with a receiver (rca to rca), then a small single pair from CAT5 cable (just cause I have a bunch)

receiver and DAC
some 24ga PVC wire I picked up (stranded)

DAC and Balanced Output Sockets
pairs from CAT5, re-wound into three wire sets instead of pairs (see reason above)
can be see here used with an embedded BETA Opus

power supply (yours) and components
some 24ga PVC wire I picked up (stranded)

I am building a Cd player from scratch, but am new to this.
I wanted to know where you think I should install the power switch.

Should I have it switch the HV before the transformers?
Have it Switch after the Transformers but before the PS?
Have it switch after the ps (before the DAC)?

Thank you
Darren

I've finally gotten around to doing some comparisons with the Opus. Against my Zhaolu D2.5a with a Zapfilter installed, I prefer the Opus in most cases, with the most common edge to the Zapfiltered Zhaolu being bass volume (not necesarrily quality). The Zhaolu might also do sax a little bit better, as well.

I don't have any buffer installed in my Opus at the moment...would adding something like the Zapfilter make the bass more present? My guess is that it would, but I'm relatively new to this

Are you using it with single-ended outputs?

Balanced outs. The bass is there and is pretty good...I'm just a bit of a basshead

Huh?

Does anyone know where to source TORX? I need to add an optical input to my DAC but can't seem to find one of these anywhere. Also, can a simple DPDT switch be used to switch back and forth between coax and optical, or will I need a more complex circuit. Thanks, guys
