As a current U16 owner, and the starter of this thread...the DI20 is on my radar for sure. I would like to ask collectively to those who KNOW: I currently have all my gear plugged into a PS Audio P20 Power regenerator...so is it overkill, not necessary, waste of money, silly...you fill in the blank...for me to consider the HE version over the standard version??? If I was to purchase the HE version and plug it into my P-20, would that be detrimental? My gut says: get the better power supply, but considering the extra costs of the HE, I could definitely use the savings for cable upgrades, etc. I am asking for some concrete advise, as opposed to "wild-ass-guesses", which I already have plenty of. Thanks in advance, Y'all!
