Ayre's new Minimum Phase filter


Has anyone heard Ayre's new CD players or its new DAC with the Minimum Phase filter or has anyone returned his or her C-5xe for upgrade with the new MP filter? If so, what do you think of the sound?

I think their new USB QB-9 DAC with MP filter is the most exciting new product of 2009, although I haven't heard it yet.
That is what I am trying to find out from Michael at Ayre. Left a voice mail with him on Mar. 18, a second voice on Mar. 23, never get a response from him.

Is that the service level we expect from a company with a top tier customer service? Can't imagine how long does it take to do the MP upgrade.
Finally get a response from Michael at Ayre today. The owner of the C5XE need to go thru your local Ayre dealer to arrange with Ayre for the upgrade. The cost is about US$200 plus shipping.

Michael indicated that the earliest upgrade appointment available is early June, 2009.
i upgraded mine and noise i used to hear on some SACDs (in back ground during quiet classical music) is gone. a year ago charles hansen and i e-mailed each other back and forth many times as i was shocked that there would be this much noise on certain cds. there was some denial on their part in regards to this noise (the dealer heard it). customer service is a bit slow at Ayre, but they do come through in the end. can't beat this machine at even 10k. it's amazingly good for the redbook and hi rez formats digital world. compared to my 30k analog rig, it does well, and it's beauty and costs very little. i do like the upgrade. backgrounds disappear even more, music seems to slow down ( always a good sign in my ear to brain connection and processing centers). the flow seems more natural (hate to say analog, but u get my drift). that Ayre would do this for 200 plus shipping is a gift. they may be slow to answer the phone (they were for me), but they are a small company. but geez, see what they gave us. i have never hung on to one cd player longer than this. i may have had my differences with charles hansen, but it's all good with the C5XE. they could easily have built and sold us a new player rather than upgrade the C5xe. kudos ayre
