I went with the Teddy Pardo one. It is more expensive than any of the PSUs listed (I believe it is ~$400 or thereabouts) but it is the only one based on a superior superregulator design, giving superior results. I can't recommend it highly enough.
Ordered a CIAUDIO VDC5 MKII for my SB Touch and should arrive this week. I only use Touch for internet radio directly connected to mysqueezebox.net account bypassing my computer.
I'm using all unshielded ICs and SCs so want SPS out of the system and if VDC5 improves the sound, all the better.
CIAUDIO VDC5 MKII arrived for Touch (ONLY use digital out to DAC) this week and it made a HUGE improvement.
Typical improvements with higher quality PS. Quieter, image more stable, sharper and control, more transparent, more detail especially the bass ... should improve further with more hours.
I went for the CI VDC12 kit and am very impressed too
The build quality is excellent and was just what I wanted.
Hooked it up to my QuteHD, and wow, it really does unlock the full potential of this DAC. It has definitely "smoothed" things out taking out some high frequency harshness which brings out more sharpness and details.
Even though everyone swears by these linear PSU' I did not want to believe it but now I am a believer.
Another great bang for the buck product right there with my lightspeed attenuator :)
