桑多杂志的这些大佬们,他们没有一人是混进来的,都是靠真本事堂堂正正地端着这个饭碗,几十年如一日白天守着来自全世界的顶级器材,一个电话一个email就能得到想听的任何录音,晚上可能和这一行顶尖的工程师一起喝着小酒儿。。。什么好?什么糟?这个有可能听不明白吗? 如果他们指着一个器材,对我傲慢地说一耳朵听下来如何如何,我是质疑呢还是宁可相信他的话呢?所谓观千剑始知剑,我选择相信。

Hello Michael,
Thanks for the note on the coming upgrades for the Ayre USB D/A converters, the DX-5-DSD and the QB-9-DSD. In the mad rush of CES, you swapped the photos and posted the picture of the DX-5-DSD that was in our active system. (The only facelift is the addition of the "DSD" logo below the Ayre logo.)
On the DX-5 we made improvements to both the analog output stage and its power supply. We also replaced the Burr-Brown DAC chip with an ESS Sabre and the clocks with some lower jitter modules. The DSD logo is because we have also added the "DSD over PCM" (DoP) capability so that one can stream downloaded DSD files from your computer to the DX-5-DSD. The sound from the analog outputs is significantly improved, but there are no improvements to any other part of the player. Therefore it only makes sense to purchase the upgrade if you are using the analog outputs. We are going to try one other change to see how much improvement it makes (we didn't have time before CES) and then release the new version by the end of January. The expected US retail price increase will be in the range of 5% to 10%, and older units will be fully upgradable for around the same price.
We will apply many of the same upgrades to the QB-9, to be called the QB-9 DSD. In this case we want to keep the US retail below a certain price point, so we don't know haw many of the changes we will be able to include.That unit should be shipping in mid-February. Again the sonic improvement will be substantial, and the price increase and also the upgrade cost will be very reasonable.
Best regards,
Charles Hansen
