Апгрейд CD-плеера CEC-2100

Оригинальное состояние:

"...Most audiophiles think of Sanyo as a company you might buy a refrigerator from, but not a high-end audio product. So when you find out that the CEC CD-2100 CD player is manufactured by the Optronics division of Sanyo, that's likely to be a turn-off. But this is a CD player you shouldn't dismiss just based on a brand name. CEC was an independent company with a quite successful business making CD transports before they were purchased by Sanyo. While not as familiar as companies like Sony or Pioneer, you'll find CEC parts inside a number of products well known to audiophiles. The Parasound C/DC-1500 I own (and its single-disc cousin the C/DC-1000) are both based on CEC transport units. The CEC CD-2100 certainly has a lot more in common with those units than it does with the kind of products you'd normally associate the Sanyo name with.

When you look at it from a distance, the CD-2100 looks like it's made of fancy machined metal. It's quite an impressive illusion; it's not until you get very close that you see it's actually all just plastic. While the overall construction quality seems fitting for the modest retail cost, some parts really stand out as exceptional. The RCA jacks are easily the best I've ever seen on any component that's under $500. It wasn't until I stacked the CEC and Parasound players on top of one another that I realized the jacks are actually the same ones used on the $650 C/DC-1500. Along with the coax digital output, the CEC CD-2100 has a detachable IEC power cord, so it has excellent upgrade potential. I found the actual disc tray a little on the flimsy side, even compared with the less expensive AMC CD9. But there doesn't seem to be anything that's easily breakable on it, so I'll chalk that up to a look and feel issue rather than a performance one.

A prominent label on the front of the player alludes to improved performance from a "3rd overtone oscillation" circuit. CEC uses a quartz oscillator that's been tuned to cut the fundamental to 1/10th of its normal value. The 3rd overtone harmonic is used instead for the system clock, a change that they claim significantly reduces jitter in the DAC section and allows mating with a broader selection of digital chipsets...."
