Processor DACs

First of all, I too am considering the purchase of the Anedio U2 for use in my PC-based 2 channel system, so I need to tag this thread. Second of all, the advantages of an outboard DAC over the DACs in a processor include the following:
Better output stage
Better power regulation
Better shielding from RFI and ground loop hum
I should note these comments are specific to 2-channel music. I run two systems, one Denon-based HT system, and one component system for 2-channel music only. My 2-channel setup mops the floor with the HT system when playing redbook audio. Another big difference is the pre-amp and volume pot in a component system, HT processors cannot compete with these IMHO, but YMMV etc.

I have a similar question. Currently have a Mac Mini as a source and an Anthem AVM 50v processor. All of my sources (Mac Mini, Oppo BDP 93, and DirecTV) are hooked up to the Anthem via HDMI only, and I am using the DACs in the Anthem for all sources. I have wondered whether it would be worth it to use an outboard DAC for my 2-channel music. I use the Mac running PureMusic almost exclusively for 2-channel music. How expensive of a DAC would I need to noticeably improve upon the Anthem? Opinions welcome.

I am interested in hearing people's opinions as well.

After much research trying to fix my own issues in my basement office's 2-channel setup, I recommend a DAC or a USB-SPDIF converter that has a specific clock for 44.1 kHz music (anything ripped from normal CDs). All of my music is Redbook. Most DACs/converters out there only have one clock, and that clock upsamples 44.1kHz music to 48kHz. This is called "clock synthesis," and obviously the math will produce rounding errors. The DACs and converters out there with 44.1 kHz clocks will brag about it, because very few pieces of gear have two clocks. The Schiit Bifrost's USB board has two clocks, the Anedio U2 converter and D2 DAC have two clocks, the Audiophilleo 2 has two clocks. Those are the cheapest ones I have seen that specifically say there is a clock meant to handle 44.1kHz data, and another clock to handle 48kHz data. april Music's Stello U3 is another converter that might have two clocks, cannot remember. If you are going from a laptop, a USB-SPDIF converter like this will improve your sound.
And Hifiguy5, if you buy a WFS DAC 2, skip your processor altogether and go right into an outboard amp. The DAC 2 has volume control. At least consider that as an upgrade path Maybe the processor you are looking for has inputs that go right to the amp section, bypassing the processor's volume pot?
