Bjorn-- I don't know if this will help, but my Zone Alarm firewall was preventing 9z-4 from working-

    symptoms were very similar to what you were experiencing.  Shut down Zone Alarm and

    9z-4 played fine

Hmmm...everybody seems pretty quite on this one, so I'll throw my  two cents in.

I'm listening on a pair of AVI ADM9.1's, a Veleodyne MicroVee sub with a DSPeaker anti-mode 8033 to tame the bass a bit(and it does a very good job), and a Prodigy HD2 audio card with the Toslink feeding the ADM9.1's digital input. This resides on my desk(sub is under desk), so my listening is definitely near-field.

 With that out of the way, I've been enjoying  9y-4 with arc prediction and 2x upsampling. I know, the Adm9.1's already upsample-but it sounded very good.

 Now, last night I tried 9y-5 with Engine 4 and arc prediction and 2x upsampling. Guess what, it just didn't sound right. Actually bothered my ears a bit.

 This morning I tried Engine 4 without arc prediction and 2x upsampling. WOW! Sounds REALLY good!

 Right now I'm listening to Chick Corea Akoustic Band and it has never sounded so good! My ears are smiling.

  Excellent job Peter!

 whoops..almost forgot-using Windows 7 RC.

Hi Peter-  I reinstalled Win 7 RC on the same machine but xx won't activate.
              By the way, 0.9y-4 is brilliant!

Hi Y'all- I just registered-my girlfriend said that I shouldn't check the box that says I'm over 10 years old.

  Anyway, I often read that toslink is NOT a good way to go-but right now I'm listening to
a pair of AVI ADM9.1's using the toslink connection(and XXHighEnd-of course!)-and it sounds pretty damn good.
Any opinions?
