I’ve had the Cyrus CDi for 2 years before a serious upgrade recently. Highly recommended, it has the PRAT of Cyrus but is not as forward as the separate DACs from Cyrus. Highly musical and punches way above its weight. I had used it for a long time as a CD Transport and never had even tried it with its internal DAC. I only recently used it as an integrated CD player. And was very positively suprised and used it since as a stand alone CD player until my upgrade.
And just FYI, I have tried it with the PSX-R2 power supply of my Cyrus Phono Signature, I heard no discernable improvement over the stock unit. However, the addition of an Audioquest NRG-Z3 and then Audioquest Monsoon power cable hugely improved its sound. It’s a CD player that is very sensitive to it, I would recommend trying an aftermarket power cord or two if you pull the trigger.
