I agree with the thoughts of the others, in as that the Opus 21 is an excellent CD player. Another good aspect of buying one is that the customer service is second to none. (Dealing with the owner, Jeff Kalt, is a pleasure.)
The sonics of the Opus 21 are more analog like than most other CD players I have heard, and since I love analog first and foremost, that is a big plus to me. (Now, to be perfectly honest, I still prefer my analog source to this CD player, but then again, I have put quite a lot of money into it to acheive such sonics.)
I like this CD player so much that I have had virtualy no desire to upgrade it since I purchased it six years ago, and it is one of the oldest pieces of equipment I own. Highly Recommended.
