Another option, which I am in home auditioning right now, is the PS Audio Stellar Gain Cell DAC/Preamp and M700 monoblock ensemble, which can be purchased new for $2799 with a $1200 trade-in against the $3999 package price. I already have the Preamp and have been running it for a week through balanced inputs on my Manley NEO250 monoblocks. This preamp lives up to its name and sounds wonderful. My Wyred4Sound DAC2SE with femto clock is being traded in against this combo. The amps will arrive Tuesday and I can’t wait to try them out. I have been holding off on Class D amplification for the system for years but from what I’ve read recently it seems the implementation may have crossed the sonic threshold of my requirements. We’ll see. 30 day in-home trial can’t be beat; trade in shipment not expected until after the trial has completed. This is the way it should be done these days.
