My bet is YES...you will surely hear an improvement, and I have never even heard the Orchid; but I say so after owning 2 non oversampling DACs, which I consider to be far more natural sounding than other good DACs I owned previously. It's hard It's hard to explain the difference until you hear it, but when you do hear it, it's obvious.
Will I notice a difference?
I currently have an Exemplar/Denon 3910 CD player ( a Denon unit modified at great cost by John Tucker) and a Cambridge Audio CXN streamer. I'm thinking of getting an Mhdt Orchid dac but will I hear a difference or rather improvement ? I've tried sub $1000 dacs like Topping D50 and heard no difference at all. Guess I'm tending to be cynical about external dacs but would appreciate some informed opinions.
