Recommend a 20A power cord?

I have the Rowland Model 10 (which employs the digital switch mode power supply) and use the Model 11 from the Custom Power Chord Company (CPCC). It's reasonably priced ($300? for 4 feet) considering the state of high end audio. Check out the reviews in TAS of the Rowland Model 8Ti.

My response does not address any qualitatve differences between the Jeff Rowland Model 10 and Model 8T. I was pointing out that the TAS reviewer suggested that the Model 8T greatly benefited from the use of CPCC's after-market power cord. If we accept that observation- then by extension other Rowland power amplifiers may similarly benefit. As an owner of a Model 10, I have found this to be the case. In my experience, CPCC's Model 11 (20AMP-IEC) power cord provided a significant performance upgrade. Please consult TAS Issue No. 121 (p. 123) for a review of Rowland's Model 8T.
