goob et al- thanks for generous offering of opinions. Its great that you have such strong views. You inspired me to purchase my ciaudio dac and revelation power cable. I've purchased and received the a cambridge azur 640p phono pre, I'm using the Bolder power supply with it (from my old Art DI/O dac), it works and 'seems' to deepen the base end? The 640p plays through tubed rogue preamp. It doesn't hide bad recordings and great ones like (i'm listening to now) p. methany's 'as falls wichita, so falls wichita falls' sound great!
