I recently picked up the Sim Audio Eclipse used from another A'gon member. It was an older Eclipse (3 years old) w/ the separate power supply. For me it was a huge upgrade from my prior CD player, a consumer quality/lo-fi Yamaha 5 disc changer. I have not heard the Audio Mecca so I unfortunately can't do the A-B comparison you want. The sound quality is astounding w/ the Eclipse. Caveat: as all the Eclipse reviews have stated, you need to "bridge" the BNC to BNKC - SPDIF in/out digital gap to really get what you paid for. & my what a difference in sound quality when the gap is bridged. The sound just jumps out at you in a 3-D fashion, with amazing micro-detail. I finally got the sound I was looking for: getting lost in the music, to the point where you can feel you're at a live musical venue when you listen. For people upgrading their sources, the Eclipse is an impact product: it will make an audible difference for the better in sound quality.
