Hello Golfrok,
I assume the Metronome player you are referring to is the CD2v Signature. I’ve owned this player now for a year and I’m very happy with it. It is very smooth and detailed in the mids and gives a good amount of extension on both the high and low ends. The one issue I've had until very recently is the tubes. Since I purchased this player, I've wanted to find the best tubes for it. I've gone through many, Mullard 6dj8, Tesla, Amperex, Amperex Bugle Boy, Philips, Jadis, Nationals and finally the tubes that I have in now, the West German Telefunkin 6dj8. These tubes are by far the best of the lot and they have helped solidify my opinion of this player. Not to say that I did not hear the sound qualities I mentioned above from this player with the other tubes in it, I'm just hearing them much better with the Telefunkin tubes. I highly recommend this player although I've heard some very nice things about the Audio Aero Prima but I have not heard the Prima personally. Good luck with your search and happy hunting.......John
