有在備份發燒母片的朋友, AMQR 真的好用,
昨天先用 EAC rip 蔡琴SACD之 CD層, 在用我的 Plextor Premium-2 (YAMAHA CD_RW also supports AMQR)上啟動AMQR 4x燒入太陽誘電的CD-R空片
母片和備份片分別用Pioneer989 via iLink 撥放, No Difference At all, 聲音乾淨低頻一樣渾厚~~~真滿意

小弟分別 enable/Disable AMQR 各燒一張, 光肉眼就看的出燒錄軌跡之不同, AMQR enable 時, CD-R光環又滿又深色...爽度100

With Yamaha's Audio Master Quality Recording (AMQR) you have the power to create studio-quality audio masters that not only sound better, but can also increase the life span of your valuable recordings.
Key Benifits of Audio Master Quality Recording:

[size=-1]Significantly Reduce Jitter by up to 30%
Improve Playback Compatibility
Long-term Readability
Reduce the Possibility of Skips and Pops During Playback

[size=-1]Significantly Reduce Jitter by up to 30%
Audio CDs burned using conventional methods display considerably higher jitter values (audible playback errors) than pressed CDs. The Advanced Audio Master Quality Recording feature reduces jitter values by up to 30% in order to achieve the best possible sound quality from your recorded audio discs. Enjoy improved audible clarity, fuller bass reproduction and improved stereo sound separation.

[size=-1]What is Jitter?
[size=-1]ACD-R/RW drive writes audio in the form of pits and lands on the recordable layer of the disc. The digital information in the pits and lands is decoded by the scanning unit in the CD player and played. Various factors (e.g. component tolerances, ripple voltage, electromagnetic fields, the inconsistency of the lands and pits—their length or width and the uneven gaps between them) can prevent these signals from reaching the CD-player's scanning unit at exactly the intended time. This timing inaccuracy is what is known as "jitter".
[size=-1]High jitter values are responsible for inaccurate sound positioning, poor bass frequency and unclear sound.

[size=-1]Improve Playback Compatibility
Not all standalone CD players are designed to play recordable media. Audio Master Quality Recording can help ensure maximum compatibility on the widest range of players. You can also experience less skips on your car or portable CD player.
[size=-1]Long-term readability
[size=-1]Because pits and lands are wider, data integrity is more easily secured, helping to maintain readability under conditions where conventional CDs can become corrupted. Rest assured, audio CDs recorded with Yamaha’s Audio Master Quality Recording can keep your valuable disc safer for years to come.
[size=-1]Reduce the Possibility of Skips and Pops during Players
Now you can go for a jog confidently with an audio discs created with Yamaha’s Audio Master Quality Recording with minimal worries of Irregular skips and pops. The elongated pits and lands makes reliable audible play a breeze even on poorly manufactured mobile CD players.
[size=-1]How does Audio Master Quality Recording work?
[size=-1]Yamaha's Audio Master Quality Recording dramatically reduces jitter. Using this feature, the recorder will write longer pits and lands than when in standard mode. Thanks to a variable linear speed, CD-players will read CDs created with the feature at the same speed even though pits and lands are considerably longer. The difference is not only technical, but audible as well. This unique recording feature succeeds in a way that traditional CD recording methods have always failed. It brings true-to-press quality to newly created CD-R or CD-RW music discs.

[size=-3]Yamaha's Audio Master Quality Recording mode widens pits and lands, significantly reducing jitter during playback. In test after test, listeners proclaim they will never go back to the old way of writing audio CDs again. The results, they say, are astonishing.

[size=-1]While the CD player's laser unit reads the data, the photo detector covers a wider area per pit or land. The jitter factor remains under 20ns, or a reduction of up to 30%.

[size=-1]The result: A CD recorded using Audio Master Quality Recording is noticeably better sounding than one recorded using conventional methods. In fact, the quality of audio is nearly equivalent to that of a pressed audio CD. In addition, it is easier for CD-players, including older CD-players and car hi-fi systems, to read music that was recorded using Yamaha's Audio Master Quality Recording mode, resulting in greater compatiblity and fewer skips.
