I am thinking of getting a quality, no-nonsense, single-disc CD player for my second system. By no-nonsense, I mean no DVD, no DVD-Audio, and no SACD. My use of the term "no-nonsense" is meant as sarcasm because I do enjoy those other formats, and I have them in the system already. I would like to see if a single-disc CD player at or below $1000 would provide better CD playback than the Sony SCD-C555ES that I consider to be the best CD player in the system. A local dealer has the Rotel RCD-1072 for $700, and it looks to be a strong candidate. However, a dealer about an hour from me has the Rotel and also the Arcam CD73 for around the same price. So I plan to compare the two players. One thing that intrigues me about the CD73 is that it can be upgraded to the Arcam CD192 by swapping out one DAC board for another. This upgrade gets you upsampling, and that might be nice down the road. I know that Arcam has been offering CD player options for awhile. Has anyone performed one of these upgrades? Are they easy to do? (I should note that I owned an Ah! Njoe Tjoeb 4000 tube player for awhile, so I have played around under the hood, so to speak, before.) Also, are these Arcam upgrades expensive? Is the cost of the upgrade from the CD73 to the CD192 simply the price difference between the two players or does Arcam give you a price break? I don't know what the CD192 goes for, so I don't know how big a jump we're talking about here. Any experiences you can share would be greatly appreciated. Thanks!
