I recently purchased an Arcam irdac which I think sounds very good in my system. I am looking to improve it's performance further by replacing cheap switching power supply with an aftermarket linear supply.
There are positive reviews on various sites for Teddy Pardo Linear PS, Main Cables R Us advertises their irdac solution extensively on eBay, Custom Hifi Cables makes an interesting looking 12VAC unit, and Paul Hynes who designed the regulator for the Empirical Audio Overdrive SE makes a stand alone power supply for the irdac as well. I have also been approached by a vendor for Best of Two Worlds Power and Precision - ECO linear supply system (built by Sbooster). All are in the same ball park in terms of cost (~$400 USD delivered), and all have champions on the Internet that swear these custom power supplies noticably improve performance of small DACs over stock wall warts.
One further consideration. Teddy Pardo claims that his supplies are super quiet. I find this compelling, but am thinking that current deliver may be just as or more important for DAC audio performance.
In terms of a linear supply to improve performance of my irdac, do you have experience and a specific recommendation?
I have a dedicated 10 gauge AC supply line on it's own breaker with good outlet In residential neighborhood, so power to system is decent.
